Your hair may be damaged if it has been colored; permed; styled with heat; gunked up with styling products; or exposed to sun, wind or chlorine. If your hair has become dry, dull, limp and feels sticky when wet, it's at risk for breakage. To stop hair breakage, pick an arsenal of deep conditioning and moisturizing products, and style your hair as gently as possible.
Wash your hair less. Although it feels nice to have squeaky clean locks, the less often you wash your hair, the less hair breakage will occur. If you have greasy hair, use a dry shampoo or baby powder to help suck up the oil at your roots.
Brush your hair only when it's dry. Brushing wet hair, particularly when it is damaged, can cause additional breakage. If your hair breaks even when it is dry, use a wide-toothed comb instead of a brush.
Add 2 tbsp. of olive oil to your conditioner. Shake the bottle well, and then apply it to your hair after shampooing to help prevent breakage, suggests stylist Adir Abergel in "Cosmopolitan."
Deep condition your hair once a week with mayonnaise, suggests Steven Docherty, senior art director at Vidal Sassoon Salon. Mayonnaise contains fats and oils that help deep condition the hair to strengthen it and prevent breakage. Apply the mayo to dry hair; leave in for up to an hour, and then wash it out.
Stop coloring your hair. Even if it's been such a long time since you went au naturel that you don't remember what your natural hair color is, put down the dye bottle if you want to prevent breakage. Most hair colors contain ammonia, peroxide, alcohol and other chemicals that dry out the hair and cause breakage.
Wear a bathing cap when swimming in chlorinated water.
Consult a doctor if your hair breakage is severe, because it may be due to a medical condition.
