Tip 2: Don't over-wash your hair

The natural oils that linger on your scalp are great for your hair and washing them out too frequently can cause serious damage.  “I always recommend for my clients to wash their hair twice a week,” says Enegd. When you do shampoo, consider using a product that will help protect against hair fall, like L’Oréal Paris ELVIVE Arginine Resist X3 Anti Hair Fall Shampoo, $5.95, You may also switch your shampoo to an anti-thinning formula like Joico Cliniscalp Cleanse for Natural Hair, $32.95, Gently massage it in for a minute or two, pushing and moving the skin around your head to stimulate blood flow around the hair cells. And instead of relying on dry shampoo in between washes, Enegd recommends rinsing your hair with vinegar.
