I found Serge Normant last year, while looking for a new shampoo/conditioner that was sulfate-free so it wouldn't strip my red color. I had been using Fekkai for years, but they changed their formula to include sulfate in it, and I could tell exactly when they made the change. I don't have to use very much shampoo, I've always had to wash 2x due to amount of hair I have, but only need to wash 1x with Serge. The conditioner is absolutely fantastic, I think due to the Keravis. It goes on thick, but conditions deeply, detangles, and leaves my hair lightweight but with body. I bought this set to travel for work with, haven't tried the hairspray yet, but am sure it will be just as fantastic as the other Serge Normant products!
