Folliculitis:
Teen information

The most common locations for folliculitis include:

• Scalp
• Beard area in males who shave
• Underarms, groin, or legs in females who shave 
• Buttocks
• Thighs

Individual lesions of folliculitis include pus-filled bumps (pustules) centered on hair follicles. These pustules may be pierced by an ingrown hair, can vary in size from 2–5 mm, and are often surrounded by a rim of pink to red, inflamed skin. Occasionally, a folliculitis lesion can rupture to form a scab on the surface of the skin.

Mild and moderate cases of folliculitis are often tender or itchy. More severe cases of folliculitis, which may be deeper and may affect the entire hair follicle, may be painful.

Mild and moderate cases of folliculitis usually clear quickly with treatment and leave no scars. However, more severe cases of folliculitis may lead to complications such as cellulitis (an infection of the deeper skin tissue), scarring, or permanent hair loss.
