What Causes Folliculitis?

Folliculitis is a skin condition in which hair follicles are irritated or inflamed. These irritated follicles can be isolated to only a small area of the body or can be generalized to large body surface areas. There are multiple causes of folliculitis which include:
- Infection (bacterial, fungal, viral, or parasitic)
- Using hot tubs
- Hair removal (shaving, plucking, or waxing)
- Wearing tight clothing
- Topical or oral medication-related side effects
- Weight gain
- Frequently touching or rubbing the skin
- Skin rubbing against skin
Who Gets Folliculitis?
Virtually any patient of any age can get folliculitis. You may be more likely to have folliculitis if you are prone to ingrown hairs or irritation when shaving or otherwise removing hair, if you frequently use hot tubs, or if you are overweight among other factors.
Why Treat Folliculitis?
For many, folliculitis subsides without medical treatment as the immune system naturally fights the infection. However, you may require treatment to address persistent, recurrent, or disabling folliculitis. This condition can be painful or uncomfortable, and you may face difficulty treating it at home if you are unsure whether you have folliculitis or another condition, such as acne.
How Can I Prevent Folliculitis?
It is usually possible to prevent folliculitis by avoiding or modifying the triggers for the condition. For example, you can help prevent folliculitis by:
- Wearing loose clothing, especially when it is humid or while exercising
- Avoiding the use of hot tubs and/or ensuring your hot tub is properly maintained
- Thoroughly washing all clothing, including bathing suits, and allowing them to fully dry before each wear
- Shaving carefully or trying a new hair removal method
How Can I Treat Folliculitis?

At home, for mild cases, you can initially attempt treatment by using a warm compress about 3-4 times daily and avoiding shaving over the affected areas. If the condition persists or worsens, it is important to pursue a professional evaluation by a board-certified dermatologist to determine whether your condition is folliculitis and, if so, what is the specific cause for your folliculitis. Once the cause for your condition is determined, your dermatologist can establish a personalized treatment plan to address your condition and strategies to prevent future recurrence. Some common treatment options include:
- Benzoyl peroxide
- Glycolic acid
- Salicylic acid
- Topical antiseptics and antibiotics
- Oral antibiotics
- Isotretinoin (Accutane)

Folliculitis FAQs
Can folliculitis cause bald spots?If left untreated, severe cases of folliculitis can cause bald spots, particularly if the condition persists or recurs. Prolonged inflammation of the hair follicle can destroy the hair follicle, causing permanent hair loss and scarring in that area. If your condition persists for over 1-2 weeks, it is important to seek medical advice from a board-certified dermatologist to prevent hair loss as a result of folliculitis. Can hormonal imbalance cause folliculitis?Folliculitis is not typically caused by hormonal imbalances. Hormone imbalances more commonly cause acne rather than folliculitis. Folliculitis is caused by: infection (bacterial, fungal, viral, or parasitic), using hot tubs, hair removal (shaving, plucking, or waxing), wearing tight clothing, weight gain, frequently touching or rubbing the skin, and skin rubbing against the skin Can you have folliculitis for years?Yes, folliculitis can either be a mild and short-lived or a severe, recurrent, and chronic (long term) condition. It is important to seek professional medical treatment if your condition is chronic, as more persistent or recurrent folliculitis can be painful, uncomfortable, and disrupt everyday life. Severe, chronic infections may also cause permanent scarring and hair loss if left untreated. How can you tell if folliculitis is bacterial or fungal?Visually, it can be difficult to tell if folliculitis is bacterial or fungal. However, a board-certified dermatologist can take a swab of an active pustule and perform lab tests to diagnose if the infection is bacterial or fungal. How do you get rid of folliculitis?Mild cases of folliculitis can be treated at home. You should avoid shaving over the affected area and can trial applying a warm compress about 3-4 times a day. However, if the condition persists for 1-2 weeks or worsens, it is important to seek professional medical advice from a board-certified dermatologist. Your dermatologist can evaluate if your condition is folliculitis and create a personalized treatment plan that may include common treatment options, such as: benzoyl peroxide, glycolic acid, salicylic acid, topical antibiotics, oral antibiotics, isotretinoin (Accutane), and laser hair removal. Is folliculitis the same as acne?No, folliculitis is not the same as acne, although they can look similar. Acne is caused by hair follicles or pores clogged with dead skin cells, oil accumulation triggered by hormones, bacterial proliferation, and inflammation. Folliculitis is caused by irritated or inflamed hair follicles due to factors such as infections, hot tubs, hair removal, wearing tight clothing, weight gain, and skin rubbing against skin. While folliculitis can occur on any area of the body with hair follicles, acne mostly affects the face and sometimes the back, chest, shoulders, and buttocks. Should I pop folliculitis bumps?No, avoid picking at or popping folliculitis bumps. Picking or popping lesions can spread infection, cause scarring, and cause more folliculitis flares. What aggravates folliculitis?Folliculitis is aggravated by heat and humidity, sweat, hot tubs, wet clothing, friction, frequently rubbing or touching the skin, and hair removal (shaving, plucking, or waxing). What happens if folliculitis goes untreated?For many, mild folliculitis subsides in a few days without any medical treatment, as the immune system naturally fights off the infection. However, more persistent, recurrent, disabling cases may require medical treatment. Left untreated, folliculitis can be painful or uncomfortable and can be difficult to treat at home if it is confused with another condition, such as acne. Severe infections that are left untreated can possibly lead to scarring and permanent hair loss. |
