An SPF for the hair is a product that is applied before going to the sun for protection from damage and discoloration of the hair. Its also important to use before going into the ocean water or the pool.
This product is very important if the hair is chemically treated, colored or highlighted.
An SPF for the hair does not exist alone as an SPF for the hair but as another hair product with an SPF. It may come in a spray, lotion and sometimes in a form of leave in conditioner. Some shampoos can claim the same results but its better to apply the sun protection after the shampoo.This product can be applied on wet hair or dry hair.
