Hair Type: NATURAL

Your Goal: Protect the Hairline

Braiding your hair too tightly and twirling locks and two-strand twists can compromise the hairline, leaving bald patches behind. “Think of your hair as a delicate piece of thread, not as a rope that can be knotted and twisted,” advises Dallas-based trichologist Rodney Barnett. He suggests products with essential oils such as rosemary or peppermint to stimulate hair follicles and promote growth around the hairline.

Your Goal: Prevent Dry Scalp Concerned about a dry or an itchy scalp? Increase lubrication, especially if you use dandruff shampoos, says Barnett, because “they’re detergent-based and remove natural oils.” Try a supplement such as flaxseed oil. And drink more water, an essential for a healthy scalp. To find the right amount for daily intake, divide your weight by two and drink that number in ounces.
