Sometimes, as is the case with natural ingredients, a product needs to be used more than once in order to see some effect. We recommend waiting 24-48 hours between uses and leaving the Curl Power on for 2 hours or more if necessary. It's also important not to use a chemical shampoo, which contains Sodium Lauryl Sulfate, SLS, when washing the curl power out as it'll strip everything from your hair. Curl Power coats the hair and nourishes it, similar to a protein treatment. If you find that our shampoo is too clarifying, rinse the Curl Power out first thoroughly and see if that helps. Curl Power is so natural and gentle you do not have to fear any damage if you happen to leave a small amount behind!
