I've been using this shampoo for over a year now! I used to have dry, flaky skin on my scalp which I wasn't sure was dandruff or psoriasis. Nearly immediately after starting to use this shampoo, the itch, bumps, and flakes on my scalp went away. My scalp is so much healthier! I use this as a base in my shampoo routine in the shower, rub it into my scalp as round 1 and then follow with another all natural shampoo. This shampoo has no odor and has cleared up any past irritations. Note this shampoo...
