I loved this mask, which is really fast (in general it is better to let the masks in place a good time, which implies a moment of relaxation in the bath). The hair is very soft, soft, easy disentangling, feeding side is credible. The four testers were convinced.
In practice I do not see how a mask could repair the forks; may hide by encouraging hair scales cleanly to fall back on each other, but the only real enemy forks and rest ... the scissors!
However, in a preventive mode, to prevent lassèchement related to the length, the drying, repeated washing, I think that the regular use of this mask has a good chance to keep its promises.
Only downside, the different members of the family (well, the cat has not pronounced) found the smell of some strong mask.
Not unpleasant (a caramel candy fragrance that reminds me the hairdresser) but a bit too heady for our taste (well, smell ^ - ^)
(Ouhh I forgot Claudia Schiffer signed on each of our pots, she developed the product it seems, this is too much! * - *)
