Curly Hair Basics
Curly hair (Type 3) forms visible spirals or ringlets that hold their shape even without product — the defining line between it and wavy hair, which only ever forms loose S-bends. Within Type 3, there's a wide range: some curls are loose and springy, others are tight corkscrews closer in diameter to a pencil. Knowing which sub-type you have changes almost every product and technique decision you'll make.
3B: Tighter, springier corkscrews roughly the width of a marker. Curls have more volume and a coarser feel than 3A, and clump more readily with the right products. See the full 3B curly hair routine.
3C: Tight, densely packed corkscrews about the width of a pencil or a drinking straw. Has the most shrinkage of the curly types and, because of how far moisture has to travel down each tightly wound strand, tends to run the driest. See the full 3C curly hair routine.
Curly hair is drier and more fragile than straight or wavy hair by design, not by bad luck. Every technique in this guide exists to solve one problem: getting moisture in and keeping it there, while giving individual curls enough structure to clump together instead of frizzing apart.
Curl pattern isn't fixed across your whole head. Many curlies have 3A curls at the crown, 3B through the mid-lengths, and looser or tighter patterns at the nape or hairline. Building a routine around your most common pattern — and adjusting product amount by section — works better than assuming your whole head is a single type.
Why Curly Hair Runs Dry
If you've ever wondered why your curly hair is always dry no matter how much conditioner you use, the answer starts at your scalp. Your scalp produces sebum, a natural oil meant to coat and protect each strand as it travels from root to tip. On straight hair, that trip is a straight line, and sebum makes it the whole way with little resistance.
Curly hair changes the geometry of that trip entirely. Every bend and twist in a curly strand is a place where sebum has to change direction, and it simply doesn't travel well around corners. By the time it would reach the ends of a tightly coiled 3C strand, sebum has navigated dozens of bends — and very little of it actually gets there. The tighter the curl, the more bends per inch, and the drier the hair tends to run, which is why 3C hair is typically drier than 3A hair even on the same head.
This is a structural reality of curl geometry, not a sign that your scalp is unhealthy or that you're doing something wrong. It just means curly hair needs more deliberate, externally replenished moisture than straighter textures — which is exactly what the wash day routine below is built around.
Porosity — how easily your hair's outer cuticle lets moisture in and out — compounds this further. High-porosity curls absorb water quickly but lose it just as fast, while low-porosity curls resist moisture getting in at all. Understanding your porosity helps explain why the same products work beautifully for one curly friend and do nothing for another. For a deeper breakdown, see our hair porosity guide.

3.1Wash Day Steps
A complete beginner wash day routine for curly hair
Step 1: Detangle before you wash
Curly hair tangles more easily than straight or wavy hair because the bends in each strand catch on each other. Finger-detangle or use a wide-tooth comb on dry or conditioner-soaked hair before you even turn on the water, working in small sections from ends to roots. Skipping this step is how a five-minute wash turns into a fight.
Step 2: Cleanse the scalp, not the whole strand
Sebum barely makes it past the first bend in a curl, so your scalp can be oily while your lengths stay dry — cleansing every strand top to bottom the way straight hair does will strip curls that are already starving for moisture. Focus a sulfate-free shampoo or cleansing conditioner on the scalp, massage with your fingertips, and let the lather rinse through the lengths on its way out.
Step 3: Condition generously with squish to condish
Curly hair typically needs more conditioner than any other hair type. Apply a rich conditioner section by section, then use the squish to condish method — cup your hair underneath and squeeze upward, alternating with cold water — to help the cuticle close around the moisture and encourage curl clumping.
Step 4: Apply styling products to soaking wet hair
Curls should be dripping wet, not towel-dried, when you apply leave-in conditioner, cream, and gel. Work in sections, applying each product with a raking or scrunching motion so it coats the hair evenly and encourages clumps to form before the hair starts to dry.
Step 5: Plop or diffuse, then scrunch out the crunch
Either plop your hair in a microfiber towel or t-shirt for 10-20 minutes to absorb excess water without disrupting curl clumps, then air dry or diffuse on low heat. Once hair is 100% dry and the gel has formed a hard cast, scrunch gently with a small amount of oil on your palms to break the cast and reveal soft, defined curls.
If your curls clump beautifully but fall by midday, the culprit is usually too little product rather than too much. Curly hair almost always needs more leave-in, cream, and gel than a beginner instinctively wants to use.
Match Product Amount to Your Curl Type
3A: Lighter cream or a soft-hold gel. Too much product can weigh loose curls into waves — start with a walnut-sized amount and build up.
3B: Medium curl cream layered under a medium-hold gel. Most 3B curls do best with a leave-in, cream, and gel — the full "LCG" stack.
3C: Rich leave-in and curl cream, then a strong-hold gel on top. 3C curls can typically handle — and need — the most product of any curly sub-type.

Understanding the gel cast and how to break it
Gel is the single most misunderstood product in a curly hair routine. Beginners often avoid it because they picture crunchy, helmet-like hair — but that crunch is a temporary stage, not the final result. As gel dries, it forms a stiff cast around each curl clump. That cast acts as a scaffold, holding curls in place and protecting them from frizz while the rest of the hair finishes drying underneath it.
Plopping to Protect Your Clumps
Immediately after applying your styling products, plopping — flipping your hair into a microfiber towel or t-shirt and tying it up for 10-20 minutes — absorbs excess water without disturbing the curl clumps you just formed. It also cuts total drying time, which means less time for frizz-causing friction or gravity to pull curls out of shape.
Don't Touch It While It Dries
Every touch during drying breaks curl clumps apart and introduces frizz. This is the hardest rule for beginners to follow, but it matters more for curly hair than almost any other technique. Let it air dry or diffuse undisturbed until the gel cast has fully hardened.
Scrunching Out the Crunch
Once hair is completely dry — not just dry to the touch on the surface — cup sections in your palms with a small amount of oil or serum and scrunch upward gently. The hardened cast breaks apart, the crunch disappears, and soft, defined curl clumps are left behind. Scrunching too early, while hair is still damp, will undo your clumping instead of finishing it.
Common Mistakes
These are the mistakes that come up over and over with new curlies. If you're battling frizzy hair more than defined clumps, you're probably making at least one of these.
- Not using enough product: This is the #1 curly hair mistake. Beginners under-apply out of fear of crunch or weight, then wonder why their curls fell apart by noon. Curly hair generally needs a generous, confident amount of product.
- Applying product to hair that isn't wet enough: Product needs water to distribute and to help curls clump. Hair that's only towel-dried or damp gives uneven, stringy results instead of defined ringlets.
- Touching or scrunching too early: Disturbing curls before the gel cast has fully hardened breaks up clumps and creates frizz — the opposite of the intended effect.
- Brushing dry curls: Brushing dry curly hair separates every clump into a frizzy halo. Only detangle when hair is wet and coated with conditioner or slip.
- Cleansing the whole strand like straight hair: Scrubbing shampoo down the full length strips curls that are already moisture-starved. Focus cleansing on the scalp and let the rinse handle the rest.
- Skipping protein and moisture balance: Curly hair needs both structural protein and ongoing moisture. Leaning too far in either direction — all moisture with no protein, or vice versa — tends to show up as limp, gummy, or straw-like strands over time.
When CGM Fits (and When It Doesn't)
The Curly Girl Method (CGM) was created with curly and coily hair specifically in mind, which makes it a much more natural starting point here than it is for looser wave patterns. Sulfate-free cleansing, co-washing between shampoos, avoiding heavy silicones, and gel casting all tend to serve 3A-3C curls well — most of this guide's wash day routine lines up closely with core CGM principles.
CGM for Curly Hair: The Honest Assessment
What Works for Curlies
- +Sulfate-free cleansing protects moisture that's already hard to hold onto
- +Co-washing between shampoos suits scalps that don't need daily deep cleansing
- +Gel casting and scrunching out the crunch give real, lasting curl definition
- +Discourages heat styling and brushing dry hair, both of which damage curl pattern over time
- +Encourages working with your natural texture instead of fighting it
Where It Needs Adjusting
- -Strict co-washing only can leave fine or low-porosity curls with buildup
- -Silicone avoidance isn't necessary for everyone — some curlies do fine with certain silicones
- -Very tight schedules (wash days, refresh days) can feel rigid for beginners still learning their hair
- -Not every curl pattern needs the heaviest end of CGM-approved products
The honest takeaway: CGM is a strong framework for curly hair, not a strict requirement. If a rule is producing buildup, dryness, or frustration instead of better curls, it's worth adjusting rather than forcing it. Treat CGM as a set of proven starting principles you can fine-tune once you understand your own curl pattern and porosity.
- 13A curls are loosest and lightest; 3C curls are tightest, driest, and typically need the most product.
- 2Curly hair runs dry because sebum can't travel efficiently around tight bends — it's structural, not a mistake.
- 3Apply styling products to soaking wet hair, not towel-dried or damp hair.
- 4The gel cast is a temporary scaffold — scrunch it out only once hair is completely dry.
- 5CGM is a strong starting framework for curly hair, but adjust rules that create buildup or dryness for your specific curls.
