OGX Volume and Strength + Biotin and Collagen Shampoo (40 Fluid Ounce)

I had to switch up my shampoo bc my hair was becoming too flat! This Shampoo does add some volume, I've used it before, but not sure if it may just be the winter that my hair is on the flat side.

I bought this shampoo because of a letter to a doctor I read in out local paper. She like me was diagnosed with psoriasis and used this shampoo and in 2 days it disappeared. In 1995 I was diagnosed with psoriasis by 3 specialists. It ended up as soon as I used this shampoo and went to plant detergent it went away in 2 days. I by mistake used my old detergent also in a white bottle on my sheets and was still double rinsing my clothes at that time and the next morning I had what I was told was psoriasis on my scalp and my body that was in contact with the sheets. Later that day I saw the wrong bottle of detergent on the floor by the washing machine and took the sheets off and used the plant detergent and in 2 days I again was fine. It has been almost 3 years now and I will continue to use this shampoo. Same with the plant detergent.
