Folliculitis is a health condition that involves the swelling of one or more follicles of the hair. The disease may strike any part of the skin. It commonly affects areas of the body like scalp, face, cheeks, neck, arms, armpits, chest, back, groin, genital region and legs. One can also have Folliculitis on buttocks. The only areas that remain unaffected by Folliculitis are the palms and soles of the body.

Types of Folliculitis

Depending on the intensity of symptoms, Folliculitis is classified into two types :

Superficial Folliculitis

It affects the external surface of the body. In Superficial Folliculitis, rashes and papules develop on the skin surface in any area of the body except the palms and soles.

Superficial Folliculitis itself can be of different subtypes, such as :

Bacterial Folliculitis

It results from a bacterial infection, mainly of the Staphylococcus bacteria variety. A Staphylococcal Folliculitis arises due to infection from a blunt blade while shaving. An infection by the Pseudomonas bacteria can lead to Pseudomonas Folliculitis, also known as Hot Tub Folliculitis. A person usually gets it from hot wooden tubs and develops red itchy lumps within a day after exposure.

Fungal Folliculitis

It arises when fungus or yeast infects the deeper layers of the hair follicles or the skin. Tinea barbae is a well known Fungal Folliculitis. Tinea Folliculitis Barbae can result in pus-filled, deep red bumps on any part of the body.

Viral Folliculitis

It is caused by a viral infection, mainly by the Herpes Simplex Virus (HSV).

Parasitic Folliculitis

This occurs when small, parasitic micro-organisms nest themselves into the hair follicle and lay eggs there.

Deep Folliculitis

In this condition, the infection extends deep into the hair follicle and affects either the entire follicle or a deeper area of the follicle.

Deep Folliculitis can also be subdivided into various subtypes like :

Gram Negative Folliculitis

This happens in people who use antibiotics for a long time for acne treatment. Antibiotics disrupt the normal bacterial balance in the body and result in profusion of harmful organisms.

Eosinophilic Folliculitis

It is generally visible in people who are affected by HIV infection. It is also known as Eosinophilic Pustular Folliculitis.

Deep Bacterial Folliculitis

This occurs when there is deep infection of the hair follicles by the Staphylococcus bacteria. It leads to boils and carbuncles on various regions of the skin surface.

Folliculitis Symptoms

The main symptoms of Folliculitis are :

Itchiness

People affected with Folliculitis commonly suffer from itchiness in one or more parts of the body. Folliculitis on penis is especially discomforting.

Rashes

Folliculitis sufferers are often seen to suffer from rashes. Rashes may arise on any part of the body covered with skin, except the palms and soles.

Pimples

Small reddish pimples or pustules can arise close to hair follicle in regions like face, neck, groin and genital. Pustular Folliculitis can be very discomforting for affected people.

Swollen Bumps

Inflamed lumps can arise on the skin of Folliculitis patients. These can be hot and painful to touch. In later stages, a head is formed over these boils and can burst to release pus from within.

Folliculitis Causes

Some of the main causes of Folliculitis are :

Damage of Hair Follicles

Folliculitis can arise if one or more hair follicles suffer damage during shaving, due to friction with a piece of clothing or due to obstruction because of a skin trauma or some other reason. If people with curly hairs trim their scalp hair or beard too short, the hair may curve and grow into the skin causing inflammation and Folliculitis.

Bacterial Infection

Infection by the Staphylococcus Aureus bacteria or overgrowth of the Gram-negative bacteria can be a major reason behind Folliculitis.

Fungal Infection

An infection by the Malassezia furfur fungus gives rise to Pityrosporum Folliculitis, a kind of Superficial Folliculitis.

Viral Infection

An infection by the Herpes Simplex Virus (HSV) can cause Herpetic Folliculitis, a type of Superficial Folliculitis.

Parasitic Infection

Parasite infection is a main cause of Deep Folliculitis. It happens when parasites infect and lay eggs at the hair follicles.

Folliculitis Treatment

Folliculitis usually goes away within a week. However, infectious cases of this condition can be really painful and discomforting for the sufferer. Mild cases can be treated at home with antibacterial mouthwash, soaps, antibiotic ointments and over the counter medicines. For serious cases, oral antibiotic drugs and Laser Hair Removal Method are used for Folliculitis treatment.
