Folliculitis

Folliculitis is an inflammation of the hair follicles that can occur due to various factors, including bacteria, fungi, or irritation. It may result in red bumps or pustules around hair follicles and can affect any area of the body with hair. Understanding its causes and effects can help in managing and addressing concerns related to skin health.

  • What causes folliculitis in my hair follicles?
    MedlinePlusMay 2026

    Folliculitis happens when bacteria, fungi, or viruses get into your hair follicles and cause an infection. This can happen from shaving, friction from tight clothes, or small cuts in the skin around the hair.

  • Can I get folliculitis anywhere on my body?
    MedlinePlusMay 2026

    Yes, folliculitis can develop anywhere on your body where you have hair, including your scalp, face, chest, back, and legs. It's most common in areas that get shaved, rubbed by clothing, or stay warm and moist.

  • Will folliculitis affect the normal growth cycle of my hair?
    MedlinePlusMay 2026

    Folliculitis usually doesn't permanently damage your hair growth cycle, but severe infections might temporarily slow down hair growth in that area. Once the infection clears up, hair typically grows back normally.

  • Why do some people get more infections than others?
    MedlinePlusMay 2026

    Some people get more infections because of differences in their skin bacteria, immune system strength, or habits like shaving closely or wearing tight clothes. Certain skin conditions and medical treatments can also make infections more likely.

  • How long does it usually take for hair to grow back after an infection?
    MedlinePlusMay 2026

    Hair normally takes about a month to grow half an inch, so it can take several weeks to months for hair to fully regrow after an infection clears. The exact time depends on how severe the infection was and how quickly your skin heals.
