I am looking for a sulfate free shampoo for my hair, which could make them manageable. I have already tried S factor, but didnât find it effective for myself, as it could not rinse off the grease without making my hair a bit dry. Although it well suited my best friend, so I gave it to her. I want to know if there is another effective sulfate free shampoo, which can make my dry hair, look manageable, along with its direction to use. Thanks.
