TOKIO products are great for those with split ends, so I recommend this product to females. It is the treatment that would overturn the male stylists opinions, which is to “cut to make it longer”. I always tell my customers to cut once in every two visits, and use treatment every time to make the tip of the hair much stronger. There is no heaviness that comes with using treatment, so I think this is the treatment that can be used for people with fine hair. Once they try it, they will be able to experience the great result, so it is a treatment that is easy to repeat.
