One hard truth: Hair loss is mostly out of your control. “Baldness comes down to your genes,” says Frederick Joyce, M.D., founder of Rejuvenate! Med Spa and a member of the International Society for Hair Restoration Surgery. “If you have the baldness gene, there are some natural remedies that may make your hair stronger and healthier to slow your hair loss slightly—but they won’t prevent you from going bald. Still, maintaining hair health by eating well and using the right products—combined with medical-grade treatments—can really work all together to help you have a fuller, thicker head of hair.”
Skeptics (among them, Dr. Wesley) are starting to come around after a 2014 randomized double-blind study published in the American Journal of Clinical Dermatology found a “statistically significant” difference in hair density for women who used a laser comb compared with those who used a sham device. (“Comb” is something of a misnomer. The device looks like a hairbrush crossed with a cordless phone; it is glided back and forth across the scalp, roughly a half-inch at a time, usually about 15 minutes three times a week.)
The other main hair-loss treatment that was recommended by all four dermatologists I interviewed is finasteride, often called by its brand name Propecia. This FDA-approved medication is only available with a prescription, but these days, it’s found as a generic and ordered online after a virtual consultation, through start-ups like Hims, Keeps, and Lemonaid.
