### Infections That Cause Hair Loss and Their Treatments Hair loss can be caused by various infections, including ringworm, folliculitis, and others. Here’s a brief overview of these infections and how they can be treated: #### Ringworm - **Cause**: A fungal infection that spreads easily from person to person. - **Symptoms**: Round, bald patches that are scaly, red, and itchy. Fever may also occur. - **Treatment**: Oral antifungal medication for about 6 weeks and possibly a medicated shampoo. #### Folliculitis - **Cause**: Infection of hair follicles, often by staph bacteria, but also by other bacteria, parasites, or fungi. - **Symptoms**: Red, inflamed bumps that may become painful or itchy. - **Treatment**: Depends on the cause; may include antibiotic lotions, pills, antifungal creams, shampoos, or steroids. #### Seborrheic Dermatitis - **Cause**: Linked to a type of yeast; not technically an infection but can cause temporary hair loss. - **Symptoms**: Oily, irritated, and itchy skin, often in areas like the scalp, eyebrows, and beard. - **Treatment**: Over-the-counter or prescription medicines, including dandruff shampoos and medicated shampoos. #### Piedra - **Cause**: Fungal infection affecting the hair shaft, causing hard, stone-like bumps. - **Symptoms**: Bumps on hair shafts, which can weaken hair and cause it to break off. - **Treatment**: Shaving or clipping off the hair and antifungal treatments. Most of these infections are treatable, and hair usually grows back once the infection is under control. However, in some cases, infections can lead to permanent hair loss if not treated properly.
