try shampoos that do not contain sulfates or parabens. Sulfates are the chemicals that make shampoos lather up. Parabens are preservatives that cause irritation and eye problems after prolonged use. Both of these chemicals aren't healthy for you or the environment so try to use shampoos with natural cleansers---
arnica gold shampoo (bakson) this shampoo do not contain parabens and sulphates, so will not cause allergy
in your hairs. Use shampoo twice a week.
