I had bought so many shampoo for my daughter that have psoriasis. I when to the dermatologist and he recommended shampoo with tar in it. That was so strong it was making itch more. So I order on the vichy site a think was last year for the first time. I had heard of the dandruff shampoo was really good. Had a visit with the dermatologist after that and I show him what I purchased and told him from all the shampoo I tried for my daughter, spends so much money on medical products to finally the itching stop, her psoriasis is less and I use a rubber little brush to make sure the product goes everywhere on her scalp., it works amazingly good!! You don't see no more flakes on her hair.. this time i purchased two bottles! Thank you Vichy for putting pumps applicators on these shampoo bottles!! I will continue to purchase them!! I wil be making a reel on social media if some wants too see how good it works. dianecomeau12345 on IG. Her hair are so soft, less dull and more shiny then ever! This shampoo my her hair less tangle also cause the flakes used to stuck in her hair. The shampoo has a silky texture that not sticky or oily to the touch and really hydrate the scalp i recommend!
