Acid Perm An acid perm is a type of hair permanent that uses acid. Acid is a liquid that is quite corrosive, and has a pH that is lower than pH 7. Acid perms are the opposite of alkaline perms. Acid perms have a pH that ranges from 6.5 to 8.0. Permanents create a permanent curl or wave in the hair. If a permanent takes well, the hair will stay curly or wavy until it grows out. An acid perm creates a softer curl than an alkaline perm. If you are considering a permanent treatment for your hair, it is a good idea to talk to your hair care professional about which type of permanent, alkaline or acid, would work best with your hair. Make sure you ask about what could go wrong, and what damage the permanent could possibly do to your hair. With that information, you can make an informed decision about getting an acid perm or an alkaline perm. more terms explained here |
