If you just like me are struggling with a very sensitive scalp, then I can't recommend enough Vichy Decros anti-dandruff shampoo. I have had dandruff for as long as I remember and my mom would try various natural remedies (rye bread, egg, stinging nettle, onions...) and then when I was able to make the purchase decisions for myself I embarked on a journey to find something that worked for me. Luckily I found Vichy Decros which at that time and back in the country I come from is sold only in pharmacies.
This shampoo is a life saver and is pretty much the only remedy I can rely on.
