#6 – Beware of Chemicals
You need to change your shampoo if it is meant to treat your oily hair. Detergent shampoos and those designed to strip lipids and other natural oils from the scalp eventually dry your nails. Also, refrain from over washing your hands as this action weakens your nails. Dish-washing and other house-hold detergents play havoc with your hands and nails; hence, use gloves to avoid contact with these silent enemies.
