Understanding tinea capitis
When talking about tinea capitis, a common fungal infection of the scalp that mostly affects children. Also known as scalp ringworm, it shows up as itchy patches, hair loss, and sometimes swollen lymph nodes. The condition is driven by dermatophyte, a group of fungi that feed on keratin in skin, hair, and nails ringworm fungi. Knowing the culprit helps you target treatment and stop the spread.
How it spreads and who gets it
Transmission of tinea capitis typically happens through direct contact, like sharing hats, combs, or pillows with an infected person. The spores can also linger on surfaces, making schools and daycare centers hot spots. Kids are most vulnerable because they play closely together and may not practice good hygiene. Adults can catch it too, especially if they have close contact with an infected child or a pet carrying the fungus.
Symptoms start as small, scaly patches that enlarge and form bald spots. The hair in the affected area may break off near the scalp, creating a “black dot” look. Inflammation can cause redness and tenderness, and sometimes a mild fever accompanies a severe infection. Doctors usually confirm the diagnosis with a Wood’s lamp exam or by taking a skin scraping for lab analysis.
Because the infection lives in the hair shaft, topical creams alone often aren’t enough. Systemic antifungal treatment, medications taken by mouth that reach the fungus through the bloodstream oral antifungals are the gold standard. Common options include griseofulvin, terbinafine, and itraconazole, each with a specific dosing schedule that depends on the child’s age and infection severity.
While the medication does the heavy lifting, supportive care makes a big difference. Gentle shampooing with medicated shampoos can reduce spore load on the scalp and lower the risk of spreading to others. Keeping hair trimmed, washing bedding weekly, and avoiding sharing personal items are simple steps that reinforce the prescription’s effect.
If left untreated, tinea capitis can lead to permanent hair loss, scarring, or secondary bacterial infection. In rare cases, the fungus can spread to other body parts, causing ringworm elsewhere. Prompt treatment usually clears the infection within weeks, but it may take several months for hair to grow back fully.
Preventing future episodes starts with education. Teach kids to avoid borrowing hats or hair accessories, to wash their hands after playing, and to tell an adult if they notice an itchy scalp. Regular checks in schools can catch early signs before the infection spreads widely.
