Believe it or not, not ALL ALCOHOLS are bad (drying/damaging) to your hair.
There are alcohols that DON’T dry out and damage your hair. These alcohols are knows as FATTY ALCOHOLS. The most common Fatty Alcohols that you will find in your hair products are, Lauryl alcohol, Cetyl alcohol, Myristyl alcohol, Stearyl alcohol, Cetearyl alcohol and Behenyl alcohol.
Fatty alcohols are typically derived from natural sources and they are often used as an emollient in skin and hair care products. They give a smooth, soft feeling to the hair shaft by helping the cuticle to lie flat on the surface of the hair. However, if used in excess, fatty alcohols can combine with the natural sebum found on the scalp and form a sticky substance that makes the hair look greasy.
The alcohols that are drying/damaging to your hair are known as SHORT CHAIN ALCOHOLS. The most common Short Chain Alcohols that you will find in your hair products are ethanol, SD alcohol, SD alcohol 40, Alcohol denat, Propanol, Propyl alcohol and Isopropyl alcohol.
