Liquid Keratin promises to deliver smoother, straighter, stronger hair for 60 days with continued smoothness and silkiness with consistent use of the product. Unlike some other treatments promising silky hair, this product is formaldehyde and aldehyde free and it contains shea butter. I usually shy away from straightening my natural hair in general especially using straightening agents because I do not want to change the texture of my hair. However, I have heard so much about Liquid Keratin’s line, I decided to give it a try.
