This shampoo leaves my locs squeaky clean! It smells really good and lathers up nicely. My roots are especially happy after a wash with the rosemary shampoo because it doesn't over dry them. It's a great clarifying shampoo to use in tandem with an apple cider vinegar cleanse (look up the proper recipe so you don't damage your hair). Effectiveness Love that squeaky clean feeling! Scent Lovely mint and botanical scent. Compliments my peppermint Castille soap.
