I have purchased this product from Germany because my boyfriend has dandruff issues and my hair tends to be quite oily. I cannot evaluate it with certainty because we have only been using it for two weeks. However, I have noticed that the skin on his scalp is noticeably cleaner (although the dandruff has not completely disappeared) and the product has not caused any side effects for him (itchiness, irritation, etc.). As for me, the tendency for oiliness has improved, perhaps because it contains menthol and alcohol in its ingredients(?).

Its texture is like water, resulting in the hair not sticking at all after use! Everything is fine so far, but I have one objection... its smell. It is terribly (in my opinion) intense and overpowering. It is indescribable and easily- something between moldy forest foliage with a hint of mint and eucalyptus? Expired old spice fragrance? I don't know, it doesn't seem to bother my boyfriend (maybe because he is tall and it doesn't bother the others either :-P) I only use it at night because, due to my job, I wouldn't want to smell like the aforementioned description...

Its use is simple: we apply a small amount to the scalp and gently massage with the fingertips (not rubbing, it evaporates in seconds). In a forum, I have read that some people pour it into a small dish to facilitate application... I think it depends on how much each person wants to use in the end.

As for the quantity (2 people, 3ml per person, once a day), I estimate it will last 3-4 weeks. Its price is "good" compared to other hair tonic products on the market. I think it suits men more than women (scent-wise). For now, we will continue using it until the end.
