Tested on long hair, fine, colorful and quickly damaged. I am very happy with this mask! My hair is very soft after the 1st use. They unravel faster. Like all masks, you have to wring out his hair after shampooing, using a towel before applying. The recommended exposure time is short: 1 minute. The texture and smell are very pleasant. The price seems very reasonable to me, especially since three pots will hold a while, even if used 2-3 times a week as recommended! (Personally, once a week, that's enough!)
