Keeping your scalp stimulated and free of buildup is essential for healthy hair. Shampoos and conditioners that contain a long list of chemicals can leave layers of gunk that clog the pores of your scalp. This accumulation may cause hair growth to slow, texture of the hair may become dull, over oily or brittle, and the skin underneath your hair may become itchy and irritated. That is why it is important to find a pure shampoo and conditioner that can clean and moisturize without the toxic ingredients.
