How to Read Hair Product Labels Without Getting Fooled

Ignore the front of the bottle

Marketing copy ("hydrating," "repairing," "salon-quality") is regulated loosely in most markets. What matters is the INCI list on the back — the International Nomenclature of Cosmetic Ingredients.

INCI is required by law in EU, UK, UAE, most of Asia, and loosely in US. Ingredients are listed by weight, from highest to lowest.

The first five ingredients matter most

The first five usually make up 70–90% of the formula. Everything after 1–2% is mostly "fairy dust" — there for marketing.

Quick read:

1. Usually water (Aqua)
2. Main surfactant (shampoo) or main conditioning agent
3. Secondary surfactants or emulsifiers
4. Texture/slip agents (fatty alcohols)
5. First "actives" or thickeners

If the hero ingredient they market is at position 10+, it's barely there.

Key surfactant types (shampoo)

Harsh (strip hard):

• Sodium Lauryl Sulfate (SLS)
• Ammonium Lauryl Sulfate

Moderate:

• Sodium Laureth Sulfate (SLES) — milder than SLS
• Cocamidopropyl Betaine (common mild secondary)

Gentle:

• Sodium Cocoyl Isethionate
• Decyl Glucoside
• Coco Glucoside
• Sodium Lauroyl Methyl Isethionate

Conditioning agents

Light:

• Behentrimonium Methosulfate
• Cetrimonium Chloride

Medium:

• Fatty alcohol, conditioning. NOT drying.">Cetearyl Alcohol (not drying — fatty)
• Stearyl Alcohol

Rich:

• Butyrospermum Parkii (Shea Butter)
• Theobroma Cacao (Cocoa) Seed Butter

Silicones — the good and the bad

Water-soluble (wash out):

• Dimethicone Copolyol
• PEG-modified names
• Amodimethicone (ish — partly)

Non-soluble (build up):

• Dimethicone (unless prefix is water-soluble)
• Cyclomethicone
• Cyclopentasiloxane

Not all silicones are bad. Water-soluble versions are fine.

Red flags

Avoid or limit:

• Formaldehyde-releasers: DMDM Hydantoin, Quaternium-15, Imidazolidinyl Urea (leave-ins)
• MI/MCI in leave-in products (EU banned)
• Lilial (Butylphenyl Methylpropional) — EU banned
• Lyral — EU banned
• Alcohol denat. high in INCI (drying)
• Parfum high in INCI for sensitive scalps

Pro claims decoded

• "Natural" = meaningless; legally vague
• "Organic" = may contain 1% organic; check certification
• "Clean" = no legal definition
• "Dermatologist tested" = doesn't mean approved; just means tested
• "Hypoallergenic" = unregulated claim
• "pH balanced" = meaningful (target 4.5–5.5 for shampoo)

When to trust a claim

• "No parabens" + shows preservatives you can read = verifiable
• "Sulfate-free" + no sulfates in INCI = true
• Certifications (EcoCert, COSMOS, USDA Organic) = standards-based
• Full INCI on website = transparency signal

What Mutaly checks

Every product in Mutaly's recommendations is INCI-vetted — we exclude EU-banned ingredients and flag harsh surfactants or silicone-heavy formulas.
