Razor bumps and ingrown hairs on the bikini line are both common after shaving. Both are uncomfortable and embarrassing, and can cause scarring or severe infection. To prevent complications after hair removal, adhere to proper shaving techniques. Razor bumps and ingrown hairs will typically resolve on their own, but in severe cases, you may need to see a medical professional.
About Razor Bumps
Razor bumps are the result of bacteria that has infected the hair follicles. The bikini area naturally contains a lot of bacteria, according to Allison Vidimos, M.D., a staff dermatologist at the Cleveland Clinic Foundation. As you drag your razor across your skin, it can pick up bacteria and drag it into hair follicles. The infected follicles become red and inflamed, a condition known as folliculitis.
About Ingrown Hairs
Unlike razor bumps, ingrown hairs are not related to bacteria. After hair is removed through shaving, waxing or tweezing, it often grows back at an angle and becomes trapped underneath the skin. The hair continues to grow and coils beneath the surface of the skin, causing painful bumps. According to MayoClinic.com, chronic ingrown hairs can lead to infection and scarring.
Prevention
To prevent razor bumps and ingrown hairs, wash the area with an antibacterial soap before shaving to reduce the amount of bacteria. Always shave in the direction of the hair growth. Shaving against the hair growth can obstruct the hair follicles and cause hairs to grow in at an angle. Manhattan cosmetic dermatologist Howard Sobel recommends using a shave gel instead of a cream to avoid clogging pores. Use single-blade razors, as double-edged razors can shave too closely and nick the edge of the hair follicle.
Treatment for Razor Bumps
For razor bumps, wash the area twice a day and apply a hydrocortisone cream to relieve redness and irritation. You may also apply an astringent or an antibacterial ointment. Wash washcloths, towels and clothes after one use to avoid spreading bacteria. Avoid shaving the affected area, which can further irritate skin and spread bacteria.
Treatment for Ingrown Hairs
For ingrown hairs, apply a warm compress several times a day to soften the skin and bring hairs to the surface. MayoClinic.com recommends washing the area in a circular motion with a washcloth or soft brush, but do not scrub the skin. If you can see the hair underneath the surface of the skin, use a sterile needle or tweezers to gently extract it and apply an antiseptic. If you have a bump but no visible hair, do not try to dig it out, as it may not actually be an ingrown hair. Continue using a warm compress until the hair is visible.
