Ingrown hair, also known as "razor bumps," are a common skin condition, particularly in people whose hair has the tendency to curl back or grow sideways in a hair follicle. The result often looks like acne, consisting of tiny round bumps, some of which have a visible hair trapped inside them. They also can be accompanied by pustules and skin discoloration. Furthermore, they can be painful and itchy as well as cosmetically disfiguring.
Women and men with coarse and/or curly hair are more prone to developing this condition, and it is more commonly seen in the African and African-American population, according to Nada Elbuluk, MD, MSc, assistant professor in the Ronald O. Perelman Department of Dermatology at NYU Langone Medical Center, who also practices at NYU's Joan H. Tisch Center for Women's Health.
Dr. Elbuluk also points out that various types of hair removal -- waxing, shaving, plucking and threading -- can lead to ingrown hairs.
Coaxing hair out of the "bump" at home by poking or tweezing should be avoided, as this can potentially introduce new bacteria into the follicle and worsen the problem. Ingrown hairs that are seriously irritated and/or infected are best treated by a board-certified dermatologist. A dermatologist can also recommend a regimen of anti-bacterial washes and creams as well as topical retinoids that can help treat the area and prevent future ingrown hairs.
Over the counter products containing benzoyl peroxide, as well as exfoliating ingredients such as glycolic acid and salicylic acid, also can help in the treatment and prevention of ingrown hairs.
"Keeping skin moisturized and exfoliated not only makes it easier to shave, but it can help remove dead skin and hairs that may clog the hair follicles, as well as promote hair growth in the right direction," says Dr. Elbuluk.
Letting hair grow is one option for avoiding the issue of razor bumps. However, if letting hair grow is not an option, Dr. Elbuluk offers some practical tips for dealing with ingrown hairs or razor bumps:
•Shave in the direction of the hair growth
•Avoid shaving over the same area multiple times
•Avoid shaving the hair too close to the skin
•Shave less often
•When using a razor blade, make sure the skin is wet before shaving and use a moisturizing shaving cream, gel, or foam while shaving
•Use of hair-removing creams or clippers instead of blade razors can sometimes help decrease the occurrence of ingrown hairs
"One of the worst things to do when having ingrown hair is to continue to shave and remove hair in the affected region," Dr. Elbuluk advises. "It is best to wait until razor bumps have resolved before going back to shaving or engaging in further hair removal at the site."
If a person is prone to developing ingrown hairs, Dr. Elbuluk suggests consulting a dermatologist about other options such as laser hair removal or use of a cream which can slow down hair growth.
