Folliculitis

What is Folliculitis?

Folliculitis is a common and usually harmless skin condition involving inflammation or infection of the hair follicles. Most cases are mild and resolve with simple self-care measures. Individuals with a more severe form and recurring folliculitis, however, may require medical help.

What Causes Folliculitis?

The condition is most often caused by a bacterial infection of hair follicles; bacterium Staphylococcus aureus is responsible for most cases of folliculitis. The inflammation, however, can also be caused by fungal and viral infection, while hair follicles can also get inflamed from ingrown hair.

Types of Folliculitis

Based on the extent of inflammation (the amount of hair follicle that is affected), folliculitis can be divided into superficial and deep with both being further divided.

Types of superficial folliculitis are:

Folliculitis Treatments

Most cases of folliculitis are mild and can easily be managed with self-care measures such as applying warm compress on the affected areas to sooth the irritation/discomfort, keeping the affected skin clean and applying a soothing cream/lotion. More severe cases may require antibiotic or antifungal treatment.
