Tinea Capitis (Scalp Fungal Infection) – Diagnosis and Treatment Guide
📌 Patient Information Section: What Does This Condition Mean?
Tinea capitis is a scalp disease caused by a contagious fungal infection, often incorrectly referred to by the public as "ringworm" (confused with Alopecia areata).
- Who is Affected?: It is most commonly seen in school-age children; however, it can also be transmitted to adults. It spreads very easily in schools, nurseries, or through the shared use of combs, towels, and hats. Transmission can also occur from cats, dogs, or farm animals (zoophilic species).
- What are the Symptoms?: It may start as slightly scaly, mildly erythematous (reddened) circular areas on the scalp. Over time, the hair in these areas weakens and breaks off at the skin level (black dot appearance). In some types, it can form inflammatory, soft, raised swellings that ooze pus upon pressure (honeycomb appearance), known as "Kerion."
- What Should be Done?: It never resolves with homemade oils or dandruff shampoos. Because it is contagious and can lead to permanent hair loss if left untreated, a specialist physician should be consulted immediately, and family members should also be screened.
🩺 Clinical & Medical Guide for Physicians
- Etiology and Pathophysiology: Dermatophyte species (Microsporum canis, Trichophyton mentagrophytes, Trichophyton tonsurans, etc.) are the causative agents. Fungal spores invade the stratum corneum and the hair shaft (with endothrix or ectothrix localization).
- Diagnostic Criteria and Clinical Findings: Scaly, grayish patch areas where hair breaks off close to the skin. In severe cases, Kerion Celsi (developing as a result of secondary bacterial infection and excessive immune response), characterized by deep, painful, purulent abscess formation, and cervical lymphadenopathy.
- Dermoscopy (Trichoscopy) Findings: "Comma hairs" formed by the breaking of the hair shaft at the skin level, "corkscrew hairs," "zigzag hairs," and gray-white scale accumulations in the follicular ostia.
- Histopathological Diagnosis and Microbiological Confirmation:
- Diagnostic Methods: Obtaining a scalp scraping or epilation sample for culture is the gold standard. Direct visualization of fungal spores (arthroconidia) within or around the hair shaft in a 10% KOH (Potassium Hydroxide) preparation.
- Biopsy and Pathology: A 4 mm punch biopsy is taken in cases of suspected Kerion or atypical cases. Fungal hyphae and spores within the hair shaft are clearly observed with PAS (Periodic acid–Schiff) staining. Dense neutrophilic and granulomatous inflammation is seen in the dermis.
- Current Treatment Protocols:
- Systemic Treatment is Essential: Topical shampoos alone are insufficient. Systemic antifungal treatments (Griseofulvin, Terbinafine, Itraconazole, or Fluconazole) should be administered for at least 6-8 weeks, calculated according to weight in children.
- Kerion Management: In the presence of Kerion, antibiotic support for secondary bacterial infection and short-term systemic corticosteroids (to prevent inflammation and permanent scarring) may be added. Family screening and cessation of shared item use are mandatory. Additionally, expertise and treatment approaches can be reviewed for clinical and surgical evaluations.

Tinea Capitis (Scalp Fungal Infection) Frequently Asked Questions
Frequently asked questions about tinea capitis (scalp fungus), its symptoms, transmission routes, and treatment approaches, provided with the expertise of Dr. Muhammet Özgehan Clinic.
Tinea capitis is a contagious fungal infection caused by fungal species called dermatophytes infecting the scalp and hair follicles. It usually manifests as scaly, dandruff-like circular crusting on the scalp, hair breakage (black dot appearance), localized hair loss areas, and sometimes inflammatory swellings (kerion). Dr. Muhammet Özgehan states that this condition is more common in children but can also occur in adults through immunity issues or contact.
Yes, the fungal infection leads to the weakening and breaking of hair strands and localized shedding. If the infection is very severe or left untreated, permanent damage to the follicles may occur due to inflammatory reactions (kerion development). Dr. Muhammet Özgehan emphasizes that early diagnosis and correct antifungal treatment are vital to protect hair follicles from permanent damage and ensure hair regrowth.
In the treatment of scalp fungus, only externally applied creams or shampoos are generally insufficient because the fungus settles in the deeper layers of the hair follicle. The current approaches applied at Dr. Muhammet Özgehan clinic are as follows:
- Systemic Antifungal Treatments: Oral antifungal drug protocols planned under physician supervision that eradicate the fungus from within.
- Medical Purifying Care: Special medical shampoos to clean crusting on the scalp and prevent the spread of spores.
- Microbiological Confirmation: Performing a fungal culture or microscopic examination (direct microscopy) for a definitive diagnosis.
In the vast majority of cases, once the infection is fully treated and the fungus is eliminated, the hair follicles regenerate and hair begins to grow back in the affected areas. Dr. Muhammet Özgehan states, however, that if permanent scarred areas have formed due to delays in deep inflammatory (kerion) cases, hair restoration options can be evaluated for these regions in the future following a physician's assessment.
Yes, tinea capitis is highly contagious; it can easily spread through direct person-to-person contact or through shared items such as combs, towels, hats, and pillowcases. Dr. Muhammet Özgehan provides the following recommendations to individuals diagnosed with this condition:
- Strictly avoid sharing personal items such as combs, brushes, towels, and hats, and wash them at high temperatures.
- Ensure family members or close contacts undergo a dermatological check-up for potential transmission risk.
- Consult the clinic without delay if itching, dandruff, or circular rashes are noticed on the scalp.
