Tinea capitis, commonly known as scalp ringworm, is a fungal infection that affects the scalp and hair follicles. This condition particularly impacts children but can occur at any age. Understanding its symptoms, diagnosis, and treatment options is crucial for effective management and prevention of complications.
While this infection is highly treatable, early recognition and proper medical intervention are essential for optimal outcomes. Let's explore everything you need to know about tinea capitis, from identifying its symptoms to understanding treatment approaches.
Key Signs and Symptoms of Tinea Capitis
Recognizing the symptoms of tinea capitis is crucial for early intervention. Common signs include:
- Circular patches of scaly, red skin on the scalp
- Brittle or broken hair that breaks off at the scalp
- Black dots where hair has broken off at the scalp surface
- Tender or painful areas on the scalp
- Itching and inflammation
- Small areas of hair loss or bald patches
In some cases, more severe symptoms may develop, including:
- Swollen lymph nodes in the neck
- Fever in severe cases
- Kerion formation (painful, inflamed masses on the scalp)
Diagnostic Process
Healthcare providers use several methods to diagnose tinea capitis accurately. The diagnostic process typically includes:
Physical Examination
The doctor will carefully examine the scalp, looking for characteristic signs of the infection, including scaling, hair loss patterns, and inflammation.
Laboratory Testing
Definitive diagnosis often requires:
- Wood's lamp examination
- Microscopic examination of hair samples
- Fungal culture to identify the specific organism
- Scalp scrapings for detailed analysis
Treatment Approaches
Treating tinea capitis requires a comprehensive approach, primarily focusing on oral antifungal medications. The standard treatment protocol includes:
Oral Antifungal Medications
Common prescriptions include:
- Griseofulvin (most commonly prescribed)
- Terbinafine
- Itraconazole
- Fluconazole
Treatment typically continues for 6-8 weeks, though duration may vary based on response and severity.
Supportive Treatments
Additional measures often include:
- Antifungal shampoos to prevent spread
- Anti-inflammatory medications if needed
- Regular scalp cleaning and hygiene maintenance
Prevention Strategies
Preventing tinea capitis involves several key practices:
- Avoid sharing personal items like combs, brushes, or hats
- Maintain good personal hygiene
- Regular washing of bedding and clothing
- Prompt treatment of infected family members or close contacts
- Regular inspection of children's scalps, especially in school settings
Potential Complications
If left untreated, tinea capitis can lead to several complications:
- Permanent hair loss or scarring
- Secondary bacterial infections
- Psychological impact, especially in children
- Spread of infection to other body areas or individuals
Frequently Asked Questions
What are the common symptoms and signs of tinea capitis (scalp ringworm)?

Some people may experience tenderness or painful areas on the scalp.
How is tinea capitis diagnosed by a healthcare provider? Healthcare providers diagnose tinea capitis through physical examination of the scalp and laboratory tests, including Wood's lamp examination, microscopic analysis of hair samples, and fungal cultures to identify the specific fungal species causing the infection.
What oral medications are used to effectively treat tinea capitis, and how long does treatment usually last? The main treatment involves oral antifungal medications such as griseofulvin, terbinafine, itraconazole, or fluconazole. Treatment typically lasts 6-8 weeks, depending on the severity of the infection and response to treatment.
Can tinea capitis be prevented, and what steps help reduce the risk of spreading the infection?
