A person claims they cured their psoriasis by stopping the use of all shampoos and soaps, and instead rinsing excess oils from their hair with grapefruit or orange juice when needed. They advise against using any special shampoos or soaps, saying these products do not cure psoriasis and just get people hooked on buying them. The technique is free and saves money compared to purchasing shampoos, as soaps harm the skin's pH balance while allowing nature to restore it to normal.
