The science

Cetostearyl alcohol helps to stabilize oil-water mixes (emulsions). It’s a fatty alcohol and a mix of cetyl and stearyl alcohol (other emollient fatty alcohols). Fatty alcohols have a long oil-soluble (and thus emollient) tail part that makes them absolutely non-drying and non-irritating, hence they are totally ok for the skin.

Benefits for your hair

Prevents dryness

As an emollient, cetostearyl alcohol is considered an effective ingredient for soothing and healing dry skin. It's great at hydrating and moisturizing, too which helps to soften the hair.

Prevents tangles 

As it's hydrating, it provides slip to help detangle hair better.
