Ingrown hair is a condition where hair curls back or grows sideways into the skin. The condition is most prevalent among people who have coarse or curly hair. It may or may not be accompanied by an infection of the hair follicle (folliculitis) or "razor bumps" (pseudofolliculitis barbae), which vary in size.
Small, solid, rounded bumps (papules),Small, pus-filled, blister-like lesions (pustules),Skin darkening (hyperpigmentation)
Steroid medicine that you rub on your skin to bring down the swelling and irritation, Retinoids (Retin A) to remove dead skin cells and reduce the skin pigment changes that can occur from ingrown hairs, Antibiotic that you take by mouth or rub onto your skin to treat an ingrown hair infection
The simplest way to prevent ingrowing hairs is to let your hair grow freely without shaving it. You may want to try this for a brief period, for relief from particularly bad spots. If you don't want to stop shaving, try the following shaving tips:use a sharp, single-bladed razor,wet your skin with warm water and use a gel,shave in the direction the hairs are growing,use as few strokes of the razor as possible,rinse the razor after every stroke,try not to shave too closely – leave a bit of stubble if you can (as bacteria can enter the tiny openings of freshly shaved skin)
