An excellent product. Of course, I didn't expect anything less from this particular company. From the third wash onwards, the reduction of dandruff and dryness is noticeable, and the itching that someone might have on their scalp is also greatly reduced. It is good to shampoo at least twice. At least for me, this worked. I am buying this product again and I recommend it. Also, it is good to leave the shampoo on for a few minutes before rinsing. This is a pharmaceutical product. It has nothing to do with those from the supermarket, which personally did not help me and actually worsened the routine I had with dryness.
Finally, I noticed a difference in the hair. It is somewhat harder and stronger after washing. Overall, I am very satisfied and of course, I will buy it again!
