I bought this out of curiosity. Recently my scalp was itchy and I felt that it's not clean enough and while shopping here I discovered this product. I'm still not sure what it is supposed to do and how much I should put on my scalp :D one tube last for 3~4 uses(?) in my case and I was using this every third day. For sure I felt that my scalp is more fresh and it's not so itchy. The smell is nice, but I think that you can't smell it after washing your hair (I'm using a "natural" shampoo without additional fragrance). Would I recommend? I'm not sure, but I think it's worth trying.
