Also known as folliculitis, it refers to the infection or inflammation affecting your hair follicles; it could target a single or more of the follicles. The hair follicles, in this case, are the small cavities that are surrounding your hair roots. The condition can take root in any part of your body, provided that hair grows in that area e.g. the scalp.

In many cases, folliculitis will occur in your armpits, buttocks, thighs, and neck—all of these are places where friction is likely to occur at any given moment. It comes in the form of small bumps and may take the appearance of a rash or acne. There are cases where it could be isolated to a single follicle, and there are times when it may affect multiple follicles. Folliculitis can either acute or chronic, with acute cases only occurring for a short duration, while the chronic cases tend to be ongoing.

Causes of swollen hair follicles?

The primary causes of folliculitis are fungi or bacteria. It is possible for a person to contract staph fungi or bacteria by coming into direct contact with someone who is already infected. Additionally, it can also be contracted by sharing personal items e.g. soap, clothing, or towels, with people who already have the folliculitis infection. The staph bacteria can be picked from using unclean spas and public pools.

Folliculitis risk factors are:

  1. Having a weak immune system
  2. Failure to shower after excessive sweating
  3. Wearing clothing that is too tight, which then ends up irritating your skin surface.
  4. Skin injuries e.g. those sustained when a person is shaving


For a physician to make a folliculitis diagnosis, the doctor will need to examine the surface areas that are either irritated or inflamed. You have to tell your medical professional:

  • The length of time you have had the bumps
  • Any other symptoms that you could be experiencing since the appearance of the inflammation
  • If you have a history of getting this condition

Apart from listening to what you have to say, a good physician can be able to tell whether a person is suffering from folliculitis by looking at the skin appearance alone. But, for the physician to be able to tell what is causing the folliculitis, a bump will have to be removed for testing purposes.

The only place that is immune from this condition is the palm of your hand.


Inflamed hair follicles appearing in the groin area are often caused by genital folliculitis. It is the swelling of hair follicles around your genital area, including the scrotum. Staphylococcus aureus is the causative factor for genital folliculitis, which mainly targets your groin area, and nowhere else. Typically, it is caused by a viral or bacterial factor, even though it can also come about when a hair follicle gets damaged leading to an infection, which then causes genital folliculitis.


The scalp is not spared as well, with inflamed follicles in this area being as a result of scalp folliculitis. The condition, which appears as small itchy pustules located in the scalp area is an inflammatory disorder targeting the hair follicles that are in this region.

Pubic area

An inflamed hair follicle appearing in your pubic area is mainly caused by the presence of ingrown hairs. These are hairs that have curled back after shaving and have begun to grow back into your skin. The result of this is the emergence of raised red spots that can easily become infected. Upon infection, they are likely to become pus-filled sores, which tend to be very painful.

Apart from being painful, an ingrown hair can also be very itchy as well as embarrassing. The good news is that with time, they can go away, without you being required to take any action at all. With ingrown hairs, there is always the possibility that your hair follicles could become infected, which may then lead to inflammation and the development of hair follicles that are pus-filled.

Folliculitis: the various types available

Folliculitis can be categorized into:

  1. Superficial folliculitis
  2. Deep folliculitis

1.     Superficial folliculitis

Its various forms are:

  1. Pseudomonas folliculitis (hot tub folliculitis)—Pseudomonas bacteria is the primary cause. You can become exposed to this bacterium in a broad range of places e.g. heated pools and hot tubs. Hot tubs and heated pools have one thing in common: chlorine and pH levels in the water are not properly When exposed, you are likely to develop itchy bumps and a red rash between one and four days after initial exposure. With time, the round bumps could develop into pustules.
  2. Bacterial folliculitis—it is very common and is characterized by appearance of white, itchy, pustules (pus-filled blisters). If this type affects your beard region, it is called as a barber’s itch, and it happens when you are exposed to the staph bacteria.
  3. Barber’s itch—it is a swelling, which is caused by the ingrown hairs in your beard region. Often, the condition affects black men who frequently shave their faces. It can also affect any person who normally gets a bikini wax on a regular basis.

2.     Deep folliculitis

It comes in the following forms:

  1. Sycosis barbae—it is common among men who have just started shaving their beards. Initially, it is characterized by the emergence of pus-filled blisters on the jaw, chin, and upper lip. As you continue shaving, these bumps could become more common.
  2. Boils—they are likely to emerge when the hair follicles have a deep staph bacterial infection. Boils are known to appear all of a sudden in the form of a red or painful pink bump. Surrounding skin could also become red, and swollen. With time, this bump could become filled with pus and may start to grow much larger, and as this happens, the amount of pain being experienced will also start to increase.
  3. Gram negative folliculitis—it is a type that can at times appear, when you are or have been receiving long-term antibiotic treatment targeting acne.

The treatment option chosen when dealing with an infected hair follicle depends on the extent of the fungal or bacterial infection. You can treat the infected or swollen hair follicles using:

1.     Topical ointments

You can also apply these ointments on your skin to reduce inflammation and swelling that may have been caused by the affected hair follicles.

Even though you can access most topical ointments over the counter, you should consider asking for a prescription from your doctor. The prescription will be provided after a diagnosis has been made to establish the causes.

But, the use of antibiotic pills has recently been limited due to the emergence of infections resisting antibacterial treatment. Often, pills are only prescribed when dealing with very severe cases.

3.     Corticosteroids

Corticosteroids can be made synthetically, but they can also be produced by your adrenal cortex, as they are a group of steroidal hormones. They are anti-inflammatories, which function by altering mediators that cause inflammation, which is one of the symptoms of an ingrown hair or an agitated hair follicle.

To use garlic in treating folliculitis, you should ingest garlic cloves at least three times each day. You can also opt for the supplement tablets, but only after consulting your physician.

It comes with curcumin—an anti-inflammatory property, that is known to cure a broad range of skin related disorders. If you want to use this particular home remedy, you will need to add a single teaspoon of turmeric powder into on cup of water. Ensure you take this solution at least two times each day to get the best results.
