This is my favorite produce and has done the most to change my hair. First of all, there are almost no nother leave in conditioners that are scent free and essential oil free. I am highly allergic and have very sensitive skin, so this is a huge deal for me. It also has changed my curly hair, making it possible not to style it and just let dry. It now feels soft, not coarse and curls in nicer way. Gets rid of some of the frizz by weighing down the hair but not making it greasy.
