At a GHD straighteners you also need the appropriate heat protection, right? Nonsense, I thought in the past, one of the drug store serves the same purpose. Far from it. There is a difference like night and day. Compared I have with almost all drugstore products: hot got2be, Loreal, Dove, Syoss and how it all. Then I decided to take me but a little more money into their own hands and try this here. It can be spread perfectly with a very fine spray, and is thus economical. I even twice a week and had the bottle already more than a month. My hair has considerably less hair breakage and split ends. I think heat protection and straighteners are simply tuned somehow perfectly. The iron glides effortlessly and "bucking" without going through the hair, a shine spray I do not need a finish well. Strong buy recommendation and a perfect score - here it really worth it to spend more money.
