I'm very pleased with all the Liquid Keratin products started out with the Shampoo and Conditioner which is also excellent than went to 30 day straight smooth strong and long treatment, and Keratin filling leave in conditioner. I also purchased the Keratin Sealing Shine Serum which is excellent and a little goes a long way.
Just have my Brazilian blowout treatment done about 3 months ago, bought this shampoo and hope it can help to maintain it. Well, hair is soften after wash but not much of a "De-Frizz" action.
Will re-purchase only if I buy the Liquid Keratin 30 Day Straight Smooth Strong and Long Treatment in the future.
