It is my favorite scalp product. I use it after the shampoo and left on my scalp for a few minutes. It has a mild cooling effect and it is really easy to wash out. After drying my hair my scalp is really clean for few days, I dont need to wash my hair so often. In a long term there are some kind of positive effect as well, e.g. my hair is growing so fast, it becames soft, and the end of my hair is not so dry. I love it! :)
