How to Read Ingredient Lists
Pro Tip
Beneficial Ingredients to Look For
2.1Humectants (Moisture Attractors)
Draw moisture from the air into your hair
Common humectants include glycerin, aloe vera, honey, panthenol (Pro-Vitamin B5), hyaluronic acid, and propylene glycol. Each works differently — explore our ingredient encyclopedia for detailed guides on how each one benefits your hair.
Climate Note
2.2Emollients (Softeners & Smoothers)
Coat the hair shaft to smooth cuticles and add shine
Natural oils like coconut oil, argan oil, and jojoba oil penetrate or coat the hair shaft, while butters like shea butter provide heavier sealing. The key difference is molecular weight — lighter oils penetrate, heavier ones seal.
2.3Proteins (Strengtheners)
Fill gaps in damaged hair and improve elasticity
Key proteins include keratin (mimics your hair's natural structure), collagen (strengthening), and rice water (gentle protein boost). They come in different sizes — smaller (hydrolyzed) proteins penetrate deeper, while larger ones coat the surface.
Caution
Ingredients to Avoid (or Use Carefully)
Sulfates (Harsh Cleansers)
Strip natural oils, cause dryness and frizz. Especially harsh on curly, colored, or damaged hair.
- Sodium Lauryl Sulfate (SLS)
- Sodium Laureth Sulfate (SLES)
- Ammonium Lauryl Sulfate
Exception: Use sulfate shampoos for clarifying (once a month) to remove buildup.
Silicones (Coating Agents)
Create a smooth coating on hair. Can cause buildup and require sulfates to remove. Not inherently bad, but incompatible with CGM.
Non-water-soluble (avoid with CGM):
- Dimethicone
- Cyclomethicone
- Amodimethicone
Water-soluble (CGM-friendly):
- Dimethicone Copolyol
- PEG-modified silicones
Drying Alcohols
Evaporate quickly and can dry out hair. Problematic in high concentrations.
Avoid:
- Alcohol Denat
- SD Alcohol 40
- Isopropyl Alcohol
- Ethanol
Fatty alcohols (safe):
- Cetyl Alcohol
- Cetearyl Alcohol
- Stearyl Alcohol
- Behenyl Alcohol
Styling & Hold Ingredients
Create hold and definition in gels, mousses, and styling creams.
- • PVP (Polyvinylpyrrolidone) — Strong hold, creates "crunch"
- • Carbomer — Gel thickener
- • Acrylates Copolymer — Flexible hold
- • Flax Seed Extract — Natural hold and shine
- • Pectin — Natural styling agent
What to Look For & What to Avoid
Use this quick-reference table when shopping. Scan the first 5-7 ingredients against these lists based on your hair concerns.
| Concern | Look For | Avoid |
|---|---|---|
| Dry Hair | Glycerin, Shea Butter, Argan Oil, Hyaluronic Acid, Aloe Vera | SLS, SLES, Alcohol Denat, SD Alcohol 40 |
| Frizzy Hair | Coconut Oil, Dimethicone, Argan Oil, Panthenol, Flax Seed | Humectants in high humidity, Sulfates, Drying Alcohols |
| Damaged Hair | Keratin, Hydrolyzed Collagen, Ceramides, Rice Protein, Panthenol | Sulfates, Non-water-soluble Silicones, Drying Alcohols, Heat without protectant |
| Oily Scalp | Tea Tree Oil, Salicylic Acid, Zinc Pyrithione, Charcoal, Niacinamide | Heavy Butters, Coconut Oil, Mineral Oil, Petrolatum |
| Thinning Hair | Biotin, Caffeine, Saw Palmetto, Peptides, Niacinamide, Rosemary Oil | Heavy Silicones, Waxes, Heavy Oils (can weigh down fine hair) |
| Color-Treated | Sulfate-Free Surfactants, UV Filters, Antioxidants, Ceramides | SLS, SLES, Clarifying Agents, High-pH formulas |
No single ingredient is universally "good" or "bad" — context matters. Coconut oil is excellent for high-porosity damaged hair but can cause buildup on low-porosity hair. Always consider your specific hair type, porosity, and concerns.
Matching Ingredients to Your Hair
- Low Porosity Hair
- Best: Lightweight humectants (glycerin, aloe), liquid oils (argan, grapeseed). Avoid: Heavy butters, coconut oil, protein (unless heat-damaged).
- High Porosity Hair
- Best: Proteins, heavy oils and butters, anti-humectants in humidity. Avoid: Lightweight products that won't seal moisture.
- Fine Hair
- Best: Lightweight proteins, volumizing polymers, panthenol. Avoid: Heavy oils, butters, silicones (can weigh down).
- Damaged/Color-Treated Hair
- Best: Proteins, ceramides, sulfate-free cleansers, UV protectants. Avoid: Harsh sulfates, drying alcohols.
Hair Care Ingredient Glossary A-Z
A quick-reference glossary of the most common ingredients you will encounter on hair product labels. Click any linked ingredient for a detailed guide.
- Aloe Vera
- A natural humectant and anti-inflammatory. Soothes the scalp, adds lightweight moisture, and improves hair elasticity without weighing hair down.
- Argan Oil
- Rich in vitamin E and fatty acids. Smooths frizz, adds shine, and penetrates the hair shaft to moisturize from within. Lightweight enough for most hair types.
- Biotin
- Also known as Vitamin B7. Supports keratin production and is associated with stronger, thicker hair. Most effective as a supplement; topical benefits are debated.
- Ceramides
- Lipids naturally found in hair that act as the "glue" holding cuticle cells together. Topical ceramides repair damage, reduce breakage, and restore the protective barrier of the hair shaft.
- Cetearyl Alcohol
- A fatty alcohol (not a drying alcohol). Used as an emollient and thickener. Softens and conditions hair. Safe for all hair types including CGM routines.
- Coconut Oil
- One of the few oils that penetrates the hair shaft due to its small molecular size. Reduces protein loss during washing. Best for high-porosity hair; can cause buildup on low-porosity hair.
- Dimethicone
- A non-water-soluble silicone that coats hair for smoothness and shine. Provides excellent heat protection and frizz control. Requires sulfate shampoo to remove; not CGM-compatible.
- Glycerin
- The most common humectant in hair care. Draws moisture from the air into hair. Works best in moderate humidity; can cause frizz in very humid or very dry climates.
- Hyaluronic Acid
- Can hold up to 1,000 times its weight in water. Provides deep hydration without heaviness. Excellent for fine hair that needs moisture without being weighed down.
- Jojoba Oil
- Technically a liquid wax that closely mimics the scalp's natural sebum. Regulates oil production, moisturizes without greasiness, and is suitable for all hair types including oily scalps.
- Keratin
- The structural protein that makes up 85-90% of your hair. Hydrolyzed keratin in products fills gaps in damaged cuticles, improving strength and reducing breakage. Use sparingly to avoid protein overload.
- Niacinamide
- Vitamin B3. Improves scalp circulation, strengthens the hair barrier, and helps regulate sebum production. Increasingly popular in scalp serums and treatments for thinning hair.
- Panthenol
- Pro-Vitamin B5. Penetrates the hair shaft to moisturize from within, improves elasticity, and adds volume and shine. One of the most versatile and universally beneficial hair ingredients.
- Rice Water / Rice Protein
- Contains amino acids and inositol that strengthen hair and improve elasticity. A gentler protein source than keratin. Popular in Asian hair care traditions and gaining widespread adoption.
- Shea Butter
- A rich emollient that seals moisture, softens, and protects hair from environmental damage. Best for thick, coarse, or coily hair types. Can be too heavy for fine hair.
- SLS / SLES
- Sodium Lauryl Sulfate and Sodium Laureth Sulfate. Harsh surfactants that create lather but strip natural oils. Avoid for daily use on curly, dry, colored, or sensitive hair. See our sulfate-free guide.
