Deep Folliculitis

There are various types of deep folliculitis, including the following:

Sycosis Barbae

This is caused in men by shaving, which can result in inflammation of the entire hair follicle. Initially, tiny pustules arise on the chin ,upper lip and jaw, becoming more widespread as shaving progresses. If the problem becomes severe, then scarring may be the unwanted result.

Gram-Negative Folliculitis

This type can occur as a by-product of long lasting antibiotic care for acne. The normal balance of nose bacteria is altered by taking these antibiotics, which can promote the growth of harmful bacteria, such as gram-negative bacteria. In most people, once the antibiotic treatment ceases, the balance is restored to normal. This is not the case for some however, as in some people the gram-negative bacteria may spread and give rise to new and sometimes severe acne attacks.

Boils and Carbuncles

When hair follicles become profoundly infected by Staph bacteria, the result can often be the growth of boils and carbuncles. A boil can swiftly appear as  a pinkish or red bump, with swollen surrounding skin. These bumps grow larger and more painful as they fill with pus, eventually bursting. Larger boils may also leave a scar. A carbuncle consists of a group of boils. As a group, it obviously will result in a much more severe infection than that of a single boil, frequently healing a lot slower and much more likely to leave unsightly scars.

Eosinophilic Folliculitis

This type is principally found in HIV sufferers, manifesting as persistent areas of pus-filled sores, mainly on the face but occasionally on the upper arms or back. The inflammation usually spreads and increase in itchiness, and frequently leaves patches of darker than normal skin.
