Pureology Hydrate vs Kérastase Nutritive Bain Satin Shampoo

Pureology and Kérastase are two of the most popular salon haircare brands. Here we compare each brand's hydrating shampoo for dry hair: Pureology Hydrate Shampoo and Kérastase Nutritive Bain Satin. The biggest difference is in the cleansing agents.

At a glance

Pureology Hydrate Shampoo

Ulta's page describes Hydrate as "a sulfate free, rich formula to hydrate normal to thick dry, color treated hair", "100% vegan" and concentrated enough for "75+ shampoos in a single bottle". It lists jojoba, green tea and sage as key ingredients. The ingredient list starts with mild synthetic cleansers (sodium cocoyl isethionate, disodium laureth sulfosuccinate) and includes silicones (amodimethicone, divinyldimethicone/dimethicone copolymer) and polyquaterniums for conditioning.

Kérastase Nutritive Bain Satin

Kérastase describes Bain Satin as a hydrating shampoo "rich in plant proteins" that "gently cleanse[s]" and restores "silky softness" to dry hair. Its full ingredient list starts with sodium laureth sulfate and sodium lauryl sulfate, and includes dimethicone, niacinamide, panthenol and hydrolyzed wheat, corn and soy proteins.

Key differences

• Sulfates. Pureology Hydrate is sulfate-free. Bain Satin uses SLES and SLS. If you specifically want a sulfate-free shampoo for color-treated hair, that settles it.
• Hair type. Pureology positions Hydrate for normal to thick, dry, color-treated hair. Kérastase positions Bain Satin for dry hair.
• Both contain silicones and fragrance.

Verdict: which should you choose?

Choose Pureology Hydrate if you want a sulfate-free, vegan shampoo for dry, color-treated hair. Choose Kérastase Nutritive Bain Satin if a sulfate-based formula is fine for you and you want a hydrating shampoo with niacinamide and plant proteins.
