Common Causes Of Folliculitis
Here are the main causes of folliculitis: (3)
- Bacterial infections: The most common cause of folliculitis is bacterial infection, particularly with Staphylococcus aureus bacteria. These bacteria can invade hair follicles and cause infection and inflammation.
- Fungal infections: Another common cause of folliculitis is fungal infection, particularly with yeast or dermatophyte fungi. These fungi can infect hair follicles and cause inflammation.
- Viral infections: Some viral infections, such as herpes simplex virus and varicella-zoster virus, can cause folliculitis.
- Blocked follicles: Hair follicles can become blocked due to excess oil, dead skin cells, or other debris. This can lead to folliculitis, particularly in areas where the skin is covered by tight clothing or where hair removal techniques have been used.
- Irritation: Folliculitis can also be caused by irritation from chemicals or other irritants, such as chlorine in swimming pools.
- Trauma: Trauma to the skin, such as from shaving or friction, can also cause folliculitis.
- Weakened immune system: Immunocompromised people, such as those with diabetes, HIV/AIDS or who are undergoing chemotherapy, are more susceptible to folliculitis.
- Certain medications: Some medications, such as corticosteroids or antibiotics, can increase the risk of folliculitis.
- Ingrown hairs: Ingrown hairs occur when hair curls back into the skin, causing inflammation and infection.
- Hot tub folliculitis: This type of folliculitis is caused by bacteria in poorly maintained hot tubs or spas.
It’s important to note that different types of folliculitis have different causes, and proper diagnosis by a medical professional is necessary to determine the specific cause and appropriate treatment.
