Why Does Hair Gray—And How to Cover It – OWNSKIN

Let’s get into the science behind it: “As hair is being formed, melanocytes inject pigment into keratinocytes—the cells containing keratin—which is the protein making up hair, skin and nails,” says Wayne, NJ plastic surgeon and hair specialist Jeffrey B. Wise, MD. “Over time, melanocytes continue to inject pigment into the hair’s keratin, which is where hair gets its color. In the aging process, melanocytes slow down and eventually stop secreting melanin, which causes a lack of pigment, and the hair turns gray.”

According to Chicago dermatologist Dr. Quenby Erickson, going gray is programmed in our genetic code, which means we can get clues as to how extensively and when it will happen by looking at our parents. However, a 2020 study published in Science Daily shows there may also be a link between stress and gray hair. When testing on mice, researchers found that the type of nerve involved in the fight-or-flight response causes permanent damage to the pigment-regenerating stem cells in the hair follicle. “The study makes perfect sense,” says Dr. Wise. “Stress is a huge factor in premature aging, as well as hair thinning. Naturally, it should also affect hair graying as well. There is also a lot of evidence that shows smoking cigarettes plays a role in making hair go gray earlier.”

Color isn’t always the only factor either; textural changes can ensue as well. “Some people are blessed with gorgeous gray hair, but for most of us, the gray is accompanied with thinning and rougher texture that leave our hair finer and harder to style,” Dr. Erickson says. There are no proven ways to prevent hair from turning gray, but both Drs. Erickson and Wise have seen some promising results from platelet-rich plasma (PRP) injections. “Because these treatments are aimed at ‘waking up’ your own stem cells, they could potentially reinvigorate melanocyte production as well,” explains Dr. Wise. “We have seen growth of darker, thicker hairs on some of our stem cell therapy patients, even though the original goal was to combat thinning. Treatment results are dependent on the patient’s individual conditions, so realistic expectations should be set by your doctor.”

Color Code

Celebrity colorists Chad Kenyon and Rita Hazan say none of their clients embraced their grays during quarantine, or they tried, but caved eventually. For those in camp “cover them up,” topical dyes and root concealers can help camouflage. “The process to cover gray hair is the same on both blonds and darker shades, but my clients with lighter hair can go longer in between touch-ups because gray hairs blend with blond hairs more easily,” says Kenyon. Celebrity colorist Aura Friedman often suggests adding a darker pepper tone to silver hair for people who feel more comfortable being darker, but don’t want the two-, three- or four-week regrowth touch-up that’s needed.

For those who want to permanently cover their grays at home, Nikki Lee, celebrity colorist and cofounder of Nine Zero One Salon, recommends Garnier Nutrisse Nourishing Color Creme ($8). “There are more than 75 shades and you can easily find your match using a virtual shade selector,” she says. “If DIY color makes you nervous, temporary root sprays are great to use in between salon appointments.
