It smells bitter, without being intrusive and can be foam well. It is recommended to leave for 2 minutes. At first I was very excited about this shampoo in fact. My hair felt well cleaned, got after a few washes before restores the luster, hardly more fat and look very much more powerful. Subjectively, I can also confirm more volume, which I attribute to the rather that my hair gradually freed from silicone.
In the meantime, I have colored my hair, which goes well with the shampoo.
Unfortunately, this shampoo a sticking point: It contains benzophenones. These are chemical UV filters are considered to be very problematic. It is to be suspected hormonal effects, as well as the reviews judging by many women resort to this shampoo, this substance can be detected by applying also in breast milk. The BUND warns explicitly against and it is also on the priority list of the EU for endocrine disrupters. As a rule, I am not a person that can be impressed by something, but this substance is absorbed through the skin and it is the shampoo so allow sufficient cleaning time. Somehow I think that's pretty uncool and also do not understand why Schauma has not waived - finally in this product it is only that the dye is not decomposed in the shampoo, so it has no bearing on the effect itself. In Schaumas Ladies Caffeine Shampoo can not find this stuff, why here?
Although I like the shampoo and its effect in itself, remains with me a bad feeling because of the benzophenone-1 and has ultimately led me to me but continue to look. Caffeine Shampoos are finally no earth-shaking innovation and this is also free of silicone oils and endocrine disrupters - all in all, but I would advise against Schaumas Hair Activator Caffeine Shampoo and inclined buyers advised to look for alternatives.
Addendum: On the day when I published this review I researched alternatives and have become aware of Balea. Their men Caffeine Shampoo is completely free from questionable substances.
Addendum Addendum: In the long run even the Balea shampoo made for my needs out as a flop. Nevertheless, who has basically uncomplicated hair / scalp and just looking for a caffeine shampoo is advised better with Balea. I unfortunately had to look further, but have now (I hope) with Wella Nioxin Starter Set System3 3-piece found the riddle.
