An inflammation or infection of the hair follicles, called folliculitis, can occur anywhere on the skin or scalp. Folliculitis, also known as ingrown hairs, resembles pimple-like eruptions or crusty sores.
Folliculitis occurs when the hair follicles are damaged by shaving, waxing or hair plucking, or by friction from clothing, according to the American Osteopathic College of Dermatology (AOCD).
The inflammation can be acute or chronic. The acute infection usually is caused by bacteria and can be treated with antibiotics. Recurring folliculitis is not as responsive to antibiotics. Instead, dermatologists usually recommend stopping shaving, waxing or plucking for three months, to allow healthy hair to grow in.
To prevent folliculitis, dermatology experts offer these suggestions:
When shaving legs, use a moisturizing shave cream or gel for a smoother, less aggressive shave.
Exfoliate skin regularly. Dry, dead skin build-up can impede the outward growth of the hair. Glycolic body washes are great for preventing impacted hairs.
If you are prone to ingrown hairs, use a depilatory or razor to remove hairs at the surface. Waxing pulls hairs from the root and the new hair that arises will be more susceptible to becoming ingrown.
Change razors frequently. An old razor is a breeding ground for bacteria that can cause folliculitis.
If you have an ingrown hair, do not pick at it with a pin, needle or finger. That will make the condition worse and can lead to infection. If it does not go away with simple exfoliation or it seems to get worse, see your health care provider.
