I have never written about products before, but this made me write; at least for me it made an impression from the first wash. It left me with soft hair with just one blow-dry, as if I had come out of a hair salon. I have been blonde for many years and have tried many products, brands, and very expensive ones. I bought this from a neighborhood hair salon to try it, and I was very satisfied. Not everything works for everyone!!!!!

Not effective at all. It makes excessive foam without cleaning the hair well. Confirmed after I straightened my hair, it always left traces of oiliness on the straightener from the scalp, which means it didn't clean it well. I wonder how they rated it as a professional shampoo.
