To prevent hair damage that may cause hair loss, follow these tips:
Go natural: Leave your hair its natural color and texture. If that is not an option for you, give hair time to recover between blowouts and chemical treatments.
Choose products wisely: Use a basic shampoo designed for your hair type. When curling your hair, choose less-damaging sponge rollers. Also, brush using a moderately stiff, natural-bristle brush, which is less likely to tear your hair.
