Curly Girl Method (CGM): Complete Guide

Chapter 01

What is the Curly Girl Method?

Curly Girl Method (CGM)

A hair care approach developed by Lorraine Massey in "Curly Girl: The Handbook" that focuses on eliminating damaging ingredients and techniques that disrupt curl patterns, causing frizz and dryness.

CGM emphasizes gentle cleansing, intense moisture, and protective styling. The method has transformed millions of people's relationships with their natural texture by helping them understand what their curls actually need.

Did You Know

The CGM has been around since 2001 and has evolved with input from the curly community. Many people follow a "modified CGM" that adapts the rules to their specific hair needs.

Chapter 02

Core CGM Rules

Look For These

+Gentle cleansers (sulfate-free shampoos, co-wash)
+Water-soluble ingredients (easy to rinse)
+Natural oils & butters (coconut, shea, argan)
+Humectants (glycerin, aloe vera)

Avoid These

-Sulfates (harsh cleansers that strip oils)
-Silicones (create buildup requiring sulfates)
-Drying alcohols (denat alcohol, SD alcohol)
-Waxes (mineral oil, petrolatum)

Other Key CGM Rules

No heat styling — Air dry or use a diffuser on low/cool
No brushing when dry — Only detangle when wet with conditioner
Use a microfiber towel or t-shirt — Regular towels cause frizz
Sleep on silk/satin — Protects curls while you sleep

How to Start the Curly Girl Method: 6 Steps

The Curly Girl Method is a sequence, not a list of products. Each step depends on getting the previous one right — people who say "CGM didn't work for me" often mis-timed the styling step, kept touching their hair while it dried, or started over leftover silicone or wax buildup. Here is the sequence.

Step 1: Clarify only if you have silicone or wax buildup

A clarifying wash is optional and contextual — not a Massey handbook mandate, and not required for every starter. If leftover non-water-soluble silicones or waxes are coating the hair, a gentle clarifying or chelating wash can help those residues rinse out so conditioner can reach the cuticle. If you already use water-soluble products, skip this and start with sulfate-free cleansing. A harsh sulfate "final wash" is community lore, not canonical CGM, and can be drying. If you do clarify, follow with a deep conditioner.

Step 2: Cleanse with sulfate-free shampoo or co-wash

Going forward, cleanse with a sulfate-free shampoo or a conditioner wash (co-wash). Focus the product on your scalp, not the lengths. Massage in circular motions for 60 seconds to lift sweat, sebum, and product residue. Most CGM beginners cleanse 1 to 3 times per week — wavy hair more often, coily hair less often. If your scalp gets itchy or flaky on co-wash alone, alternate with a gentle sulfate-free shampoo weekly.

Find a CGM-approved shampoo for your hair

Step 3: Condition and squish to condish

Apply a generous amount of silicone-free conditioner from mid-length to ends, then work some up to your scalp. Detangle with your fingers or a wide-tooth comb while the conditioner is in. Cup sections of hair in your hands and squeeze upward toward your scalp — this is squish to condish (S2C), and it forces water and conditioner into the cuticle. You should hear a wet squelching sound when your hair is fully hydrated. Rinse with cool water if you can tolerate it.

Find a CGM conditioner that works for you

Step 4: Style on soaking-wet hair

Do not towel dry. With hair still dripping, apply a leave-in conditioner first using the praying-hands method (smooth between flat palms from root to tip), then a curl cream and a curl gel. Scrunch upward in handfuls to encourage clumping. The single biggest mistake CGM beginners make is applying styling products to damp hair instead of soaking-wet hair — water is the carrier that distributes everything evenly.

Find leave-ins and gels for your curl pattern

Step 5: Plop and dry

Lay a microfiber towel or cotton t-shirt flat on a surface, flip your head forward into the center, gather the fabric around your hair, and tie it at the nape of your neck. Plop for 10 to 30 minutes to remove excess water without disrupting curl clumps. Then air-dry, or diffuse on low heat and low speed by cupping sections of curls into the diffuser bowl and holding them close to your scalp without moving them. Do not touch your hair while it dries.

Step 6: Scrunch out the crunch (SOTC)

Once your hair is completely dry, your gel will form a hard cast — this is good and means the gel is doing its job. Put a tiny pea-sized drop of light oil (argan, jojoba, or grapeseed) on your palms, rub them together, and gently scrunch your hair from ends toward scalp. The gel cast cracks and breaks, leaving soft, defined, frizz-free curls underneath. Skipping SOTC is the second most common reason CGM looks crunchy instead of bouncy.

Clarifying is optional, and contextual

Lorraine Massey, quoted in a Newsweek interview, says a sulfate "final wash" is "NOT part of the Curly Girl Method—this a myth and can be damaging to curls." She also describes sudsy, sulfate-filled shampoos as "super drying." Community guides often recommend clarifying when leftover silicones or waxes are blocking moisture. If you have that kind of buildup, a gentle clarifying or chelating wash can help. If you don't, start with sulfate-free cleansing. Hard water mineral film is a different problem — see the troubleshooting section, not a one-time sulfate reset.

The first few weeks can feel awkward. Some people notice oilier roots or flatter lengths while they change how they cleanse, how much product they use, and what residue is still rinsing out — that is habit and product-load change, not a mandatory biological "sebum recalibration" clock. Give it a few wash days to learn your pattern before you overhaul everything. There is no universal 2–4 or 4-week wait you must complete.

Chapter 04

Essential CGM Styling Techniques

How you apply products and dry your hair matters as much as which products you use. These techniques are the building blocks of defined, frizz-free curls.

Squish to Condish (S2C)

Cup sections of your hair in your hands and squeeze upward while rinsing conditioner. The squishing motion forces water and conditioner into the cuticle. You should hear a "squelching" sound when your hair is fully hydrated.

Praying Hands

Place product between your palms and smooth it over sections of hair from root to tip, as if your hair is between praying hands. This distributes product evenly without disrupting curl clumps. Best for creams and leave-ins.

Plopping

Lay a microfiber towel or cotton t-shirt flat, flip your head forward onto it, and wrap it around your hair. This removes excess water without disturbing curl formation. Leave for 10-30 minutes. Learn more in our plopping guide.

Diffusing

Use a diffuser attachment on low heat and low speed. Cup sections of curls in the diffuser bowl and hold them close to your head without moving. This dries curls faster while preserving definition. Start at the roots for volume, ends for definition.

Scrunch Out the Crunch (SOTC)

Once your gel cast is completely dry and hard, scrunch your hair with a tiny drop of oil on your palms. The cast breaks down, revealing soft, defined curls underneath. This final step is essential—never skip it.

Shingling

Apply product to very small sections and smooth from root to tip with your fingers. This defines each individual curl for maximum definition—especially effective for type 3C and type 4 hair. Learn more in our shingling guide.

Chapter 05

CGM by Hair Type

The Curly Girl Method is not one-size-fits-all. Here is how to adapt CGM for your specific hair type:

CGM for Wavy Hair (Type 2A-2C)

Wavy hair is the most prone to being weighed down by heavy CGM products. Use lightweight gels and mousses instead of heavy creams. You may need to wash more frequently (every 2-3 days) with a gentle sulfate-free shampoo rather than co-washing. Skip heavy butters and oils at the roots.See 2C wavy routine →

CGM for Curly Hair (Type 3A-3C)

This is the sweet spot for classic CGM. Use the LOC or LCO method to layer moisture. Rich creams and strong-hold gels work best. Co-washing can work for most Type 3 hair, but alternate with a sulfate-free shampoo weekly for scalp health. Deep condition every 1-2 weeks.

CGM for Coily Hair (Type 4A-4C)

Coily hair needs maximum moisture. Heavy butters (shea, mango), thick creams, and sealing oils are your friends. The LOC method is essential. Wash less frequently (once a week or less) and co-wash between shampoo days. Protective styling is a key part of CGM for Type 4 hair. Refresh with water and leave-in conditioner.

Not Sure About Your Hair Type?

Understanding your specific curl pattern makes CGM much more effective. Check our hair type chart (1A-4C) to identify yours, or take our quiz for personalized CGM product recommendations.

Chapter 06

Modified CGM: When to Adapt the Rules

Strict CGM doesn't work for everyone. Here's when you might need to modify:

Low Porosity Hair: You might need lightweight products and occasional clarifying washes. Heavy butters and oils can weigh down low porosity hair.
Fine or Thin Hair: Skip heavy creams and butters. Stick to lightweight gels and mousses. You may need to wash more frequently.
Scalp Issues: If you have dandruff, seborrheic dermatitis, or buildup, you may need to use a gentle sulfate shampoo occasionally or add a clarifying wash to your routine.

CGM vs. Modified CGM vs. Wavy Girl Method: side-by-side

The same Lorraine-Massey rulebook gets adapted three different ways depending on who's using it. Here's how the three variants actually diverge in practice — most people land on either modified CGM or wavy CGM after a few months.

Rule	Strict CGM	Modified CGM	Wavy Girl Method
Sulfates	Never after you start (clarifying is optional)	Monthly clarifying with sodium myreth sulfate is fine	Sulfate-free shampoo every wash; clarify monthly if hard water
Silicones	All silicones banned	Water-soluble silicones (PEG-, -PG-) allowed	Light water-soluble silicones for serum/heat-protect only
Cleansing	Co-wash often, sulfate-free shampoo rare	Mostly co-wash, sulfate-free shampoo as needed	Sulfate-free shampoo every wash; co-washing weighs waves down
Heat	No heat at all	Diffuser on low heat OK; flat irons / curling irons rare	Cool air diffusing or air-dry; occasional low-heat blow dry OK
Product weight	Heavy creams + butters layered	Match weight to porosity (light for low, rich for high)	Light gels and mousses; curl creams only for 2C
Best for	3A-4C, high porosity	Most people after 6-12 months — adapts to porosity, climate, hard water	2A, 2B, 2C waves — often loses pattern under strict CGM

Your CGM transition timeline: what to expect, week by week

People who quit CGM often quit in the first several weeks, when hair can look different while products, cleansing, and leftover residue change. That awkward stretch is common community lore, not a proven biological clock you have to endure. Use these checkpoints as practical wash-day notes — not follicle-cycle biology, and not a rule that you must wait a fixed number of weeks.

Week 1

First CGM wash day

If you clarified leftover silicone or wax, the first CGM wash can feel like conditioner finally reaches the hair. If you skipped clarifying because you already used water-soluble products, that is fine — just note how your hair responds. One wash day is not a verdict.

Weeks 2–4

Awkward weeks for some people

Some people notice oilier roots or limp lengths while they change cleansers, product amount, and leftover residue. That is not a proven, universal sebum-recalibration clock — sebum is largely endocrine and metabolic. If roots feel greasy, try less product on the lengths and a lighter refresh rather than assuming you must wait a fixed 2–4 weeks. Learn your pattern over a few wash days.

Month 2

Practical checkpoint — weeks 6–8

By weeks 6–8, some people notice a clearer curl or wave pattern, or a bit less frizz, as products and technique settle. That is a useful observation, not a guaranteed frizz drop or a universal timeline. Keep collecting wash-day notes — the next checkpoint is a better time to decide strict vs modified.

Month 3

Practical checkpoint — enough wash-day data

By about three months of consistent practice, many people have enough wash-day data to judge whether to stay on strict CGM or switch to modified CGM. If pattern, moisture, and shine still feel off, try one change at a time (for example, more sulfate-free shampoo and less co-wash, or a protein–moisture rebalance). Three months is a practice checkpoint, not a hair cycle — full scalp follicle cycles are measured in years (anagen), not months.

Months 4–6

Refresh + maintenance dialed in

Most people settle into a stable rhythm by month 4: a wash day every 3–5 days, a refresh routine for in-between days, and a known good product roster. Long-term hair quality keeps improving for another 6–12 months as damaged lengths grow out and are replaced by healthier new growth.

CGM acronym cheat sheet

Curl forums use a dense acronym vocabulary that shuts beginners out. Here's the working set:

Acronym	Meaning	In one sentence
CGM	Curly Girl Method	The Massey rulebook (no sulfates, no silicones, no heat).
CG	Curly Girl	Same thing, shorter.
S2C	Squish to Condish	Cup water in your hands and squish conditioner up into the hair to maximize cuticle contact.
SOTC	Scrunch Out the Crunch	After hair dries with a gel cast, scrunch with a drop of oil to break the cast into soft curls.
LOC	Liquid · Oil · Cream	Layering order for high porosity; oil seals before the cream.
LCO	Liquid · Cream · Oil	Layering order for low porosity; cream goes in first, oil seals on top.
DT	Deep Treatment / Deep Conditioner	A high-protein or high-moisture mask left on for 15+ minutes, often under heat.
ACV	Apple Cider Vinegar (rinse)	Diluted ACV used to lower scalp/hair pH, close the cuticle, and add shine.
Plopping	(not an acronym)	Wrapping wet styled hair in a microfiber towel or cotton t-shirt for 10–30 minutes to encourage curl pattern.
Praying hands	(technique)	Smoothing styling product down each hair section with flat palms before scrunching upward.
Pineapple	(overnight technique)	Loose high ponytail at the very crown of the head, on a silk pillowcase, to preserve curls overnight.
CGF	CGM Friendly / CG Friendly	Product label shorthand: complies with the no-sulfate, no- silicone rules.

Chapter 07

CGM Troubleshooting

Common issues people encounter when starting or following CGM, and how to fix them:

Hair feels waxy or weighed down

This usually means product buildup. Do a clarifying wash with a gentle sulfate shampoo or an apple cider vinegar rinse. Then switch to lighter products. You may be using too much or too heavy a conditioner.

Curls are limp and undefined

Try adding a protein treatment—your hair may be over-moisturized (hygral fatigue). Alternate between protein-rich and moisture-rich products. Also ensure you are applying styling products to soaking wet hair, not damp hair.

Scalp is itchy or flaky

Co-washing alone may not be cleansing your scalp thoroughly. Alternate with a gentle sulfate-free shampoo. Add scalp exfoliation once a week. If dandruff persists, see our dandruff guide.

Too much frizz despite following CGM

Check your porosity. High porosity hair needs more sealing (oil-based products). Also avoid touching your hair while drying, use a gel with strong hold, and try plopping instead of air drying loose. See our frizz guide.

Day 2+ curls look terrible

Sleep on a silk or satin pillowcase, or pineapple your curls (loose ponytail on top of your head). In the morning, dampen curls with a spray bottle of water mixed with a little conditioner, scrunch, and let dry. A refresh gel can also help revive definition.

CGM works in winter but stops working in summer (or vice versa)

Glycerin is a humectant that pulls moisture from wherever it's most concentrated. In high humidity it pulls water out of the air into your hair (frizz). In dry air it pulls water out of your hair into the room (dryness). Switch between glycerin-heavy products and glycerin-free / anti-humectant products seasonally — same routine, two product roster.

CGM doesn't work because you have hard water

Hard water deposits calcium, magnesium, and iron on the cuticle after every wash, which mimics the silicone-buildup symptoms CGM is supposed to eliminate. Co-washing makes it worse. Use a chelating shampoo (look for EDTA or sodium gluconate) every 2–3 weeks, and consider a shower-head water filter. See our hard water hair guide for the full protocol.

Chapter 08

Curly Girl Method FAQ

What is the Curly Girl Method in simple terms?

The Curly Girl Method (CGM) is a hair-care system created by stylist Lorraine Massey in 2001 for wavy, curly, and coily hair. The core idea is to remove the things that flatten or damage your natural pattern — sulfate shampoos, non-water-soluble silicones, drying alcohols, heat styling, and rough towels — and replace them with gentle cleansing, deep moisture, and styling on soaking-wet hair. CGM is not a single product line; it's a set of rules you can apply to any hair routine.

How long does it take to see results from the Curly Girl Method?

Some people notice a change within a few wash days; others need more time while they learn new products and techniques. There is no universal sebum-recalibration clock after you stop sulfates — oily roots or awkward weeks, when they happen, are more often about cleansing habits, product load, and leftover residue than a mandatory biological reset. By about three months of consistent practice, many people have enough wash-day data to decide whether to stay on strict CGM or switch to modified CGM. That three-month mark is a practical checkpoint, not a hair cycle.

How do I start the Curly Girl Method as a beginner?

If your current products leave non-water-soluble silicone or wax on the hair, a gentle clarifying or chelating wash can help those residues rinse out. It is optional and contextual — not a Massey handbook mandate, and not required if you already use water-soluble products. Then move to a sulfate-free shampoo or co-wash, a silicone-free conditioner, a leave-in, and a curl gel or cream. Apply styling products to soaking-wet hair, plop with a microfiber towel or cotton t-shirt for 10 to 30 minutes, air-dry or diffuse on cool, and scrunch out the gel cast once fully dry. Sleep on silk or satin and refresh between wash days with water.

What is the difference between CGM and Modified CGM?

Strict CGM bans all sulfates, all non-water-soluble silicones, all drying alcohols, all waxes, and all heat. Modified CGM keeps the spirit of the method but allows targeted exceptions — for example, water-soluble silicones (look for ingredients ending in PEG- or with -PG- in the name), occasional sulfate clarifying for hard water or buildup, low-heat diffusing, or a lightweight serum on the ends. Most long-term curlies land on modified CGM because it accommodates their porosity, climate, water hardness, and lifestyle.

Is the Curly Girl Method good for wavy hair?

Yes, but type 2 wavy hair almost always needs the wavy girl method, which is a lighter version of CGM. Heavy creams, butters, and frequent co-washing weigh waves down and flatten the pattern. Wavy CGM uses a gentle sulfate-free shampoo (not just co-wash), light gels and mousses, less product overall, and more frequent clarifying. 2A and 2B benefit most from mousse plus a soft-hold gel; 2C sits on the curly border and can usually handle a curl cream.

Is the Curly Girl Method good for low porosity hair?

Low porosity hair pairs well with CGM but needs lighter, water-based products and warmth to open the cuticle. Skip heavy butters and oils at the roots, focus on humectants like glycerin and aloe, and deep condition with gentle heat (a warm towel or shower steam). Low porosity hair builds up faster, so a monthly clarifying step is essential. Avoid protein-heavy products unless you've confirmed a protein deficiency — low porosity is more often moisture-balanced than protein-deficient.

Is the Curly Girl Method good for high porosity hair?

Yes — high porosity hair benefits from the moisture-locking principles of CGM. Use the LOC or LCO method (liquid, oil, cream layered in order) to seal the open cuticle. Deep condition weekly, add regular protein treatments to fill cuticle gaps, and finish with an oil or butter to slow moisture loss. High porosity hair often does best with cooler rinses and pH-balanced or apple cider vinegar rinses to help close the cuticle.

Can the Curly Girl Method work with hard water?

Hard water is the most common reason CGM stops working. Calcium and magnesium in hard water bind to hair, block moisture absorption, and leave a waxy residue that feels like product buildup but isn't. If you have hard water, install a shower filter, add a chelating shampoo (with EDTA or sodium gluconate) every 2 to 4 weeks, and rinse with bottled, filtered, or distilled water before styling on tough days. See our hard water hair guide for the full protocol.

What ingredients do you avoid on the Curly Girl Method?

The four banned ingredient categories are: (1) sulfates — sodium lauryl sulfate (SLS), sodium laureth sulfate (SLES), ammonium lauryl sulfate; (2) non-water-soluble silicones — dimethicone, cyclopentasiloxane, amodimethicone (anything ending in -cone, -conol, -xane, or -silane that doesn't start with PEG-); (3) drying alcohols — SD alcohol, alcohol denat, isopropyl alcohol, propanol; (4) waxes and occlusives — mineral oil, petrolatum, paraffin. Long-chain fatty alcohols (cetyl, stearyl, cetearyl) are fine — they moisturize.

Are water-soluble silicones CGM-approved?

Most CGM communities accept water-soluble silicones because they rinse out cleanly with sulfate-free shampoo or even co-wash, so they don't build up. Look for silicones with PEG- prefixes (PEG-8 dimethicone, PEG-12 dimethicone), dimethicone copolyol, or silicones with -PG- in the name. Strict CGM still avoids them; modified CGM uses them freely. They're useful for slip during detangling, frizz control on high porosity hair, and shine on type 3 curls.

Why isn't the Curly Girl Method working for me?

The five most common reasons CGM fails: (1) hard water mineral buildup — install a filter and chelate; (2) protein-moisture imbalance — alternate protein treatments and deep conditioners until your hair feels balanced; (3) using products too heavy or too light for your porosity — match weight to porosity, not type; (4) not applying styling products to soaking-wet hair; (5) co-washing alone when your scalp needs a real cleanser. Switch to modified CGM and adjust one variable at a time.

How do I do a CGM reset wash or final clarifying wash?

Only if you have silicone or wax buildup: use a gentle clarifying or chelating shampoo from scalp to ends, then follow with a deep conditioner. A harsh sulfate "final wash" is not required and is not part of Massey's method. Detangle gently, condition with a CGM-approved conditioner, and style as usual. Strict CGM avoids sulfates going forward; modified CGM may add occasional clarifying when buildup or hard water returns.

Can men do the Curly Girl Method?

Absolutely. CGM for men works on any wavy, curly, or coily texture regardless of length. The method is identical: sulfate-free cleanse, silicone-free condition, leave-in, light gel or cream, no rough towel, no heat. Shorter hair simplifies the routine — one product (a leave-in plus light gel hybrid) often replaces the leave-in/cream/gel stack. Beard hair is curly too and benefits from the same gentle cleansing principles.

What is the CGM transition period and why does my hair look worse?

Some people notice a few awkward wash days after they change products — frizzier, stringier, or limper hair while leftover residue rinses out and they learn new amounts and techniques. That is not a proven 2-to-6-week biological sebum reset you must wait out. Give it a few wash days to learn your pattern, adjust product load, and skip adding extra heavy products just to mask the awkward stage. If things still feel off after you have a few data points, try modified CGM rather than assuming you failed a clock.

How do I refresh my curls on day 2 and day 3?

On day 2 or day 3, dampen your curls with a spray bottle of water mixed with a small amount of leave-in conditioner. Scrunch upward to reactivate clumps, add a tiny bit of curl cream or gel only where needed, and let air-dry or diffuse briefly. Pineapple your curls overnight with a silk or satin scrunchie, sleep on a silk pillowcase, and avoid touching your hair when dry. Refresh sprays and foams are designed exactly for this — they extend wash days and reduce manipulation.

What is the difference between CGM and the LOC method?

CGM is a complete hair-care philosophy covering cleansing, conditioning, styling, and ingredient rules. The LOC method (liquid, oil, cream) is a single styling and moisturizing technique within CGM, used after wash day to layer moisture in a specific order. LOC is most popular for type 3C and type 4 hair, where high porosity and density demand maximum sealing. You can use LOC inside a CGM routine, inside a modified CGM routine, or inside a non-CGM routine — they're not mutually exclusive.
