The Too-Pooped-to-Party Hair

A social calendar full of celebration has given your hair major burnout.

Whip up a nourishing hair mask using antioxidant-rich coconut oil and avocado. "Coconut oil is one of the few natural oils proven to penetrate the hair shaft, so it can help strengthen from within," says Francesca Fusco, MD, assistant clinical professor of dermatology at the Icahn School of Medicine. "Plus, it can protect against heat damage." To make your mask, mix a mashed avocado with a teaspoon of the oil. (If you've noticed increased hair shedding, you can add a couple of drops of rosemary oil, which, one study suggests, can act similarly to the hair loss medicine minoxidil.) Apply from roots to ends, leave on for ten minutes, and shampoo and condition with products labeled FOR DRY SCALP. "When the scalp is healthy, your hair follicles produce stronger, thicker strands," says Fusco.
