I use a third package of three times. It is difficult to distribute on the scalp. Another drawback - the hair quickly began to become dirty, my usually twice a week, after the tools and shampoo in this series have to be washed three times. But! the effect is - much less hair falls out, the scalp does not itch, no dandruff, hair began to look healthier. Seasonal hair loss is almost stopped, I'm happy. It may take more time, but just two vials supplied to shampoo.
