An excellent product that put an end to my frizzy, damaged hair thanks to its heat activation. I ran several tests before reviewing it: on damp, wet and dry hair at various styling stages, and always before using a heat tool (dryer, straightener, hot-air brush, curling iron). I always got exceptional and, above all, long-lasting results. Definitely don't use it on dry hair if you're not going to use a straightener or similar afterwards, first because it won't serve its heat-activation purpose and second because the hair will turn sticky, which isn't the correct way to use the product. In the video you can see how frizzy and dehydrated the hair is before and how soft it looks afterwards. Five well-deserved stars.
