Trichomycosis is caused by dermatophyte fungi, mainly Microsporum and Trichophyton species, that invade the hair shaft and follicles. Infection usually spreads through direct skin contact, contact with infected animals, or shared items like combs, hats, towels, or razors.
Children, people in close-contact groups, and men who shave or trim beards frequently are at higher risk of trichomycosis. Contact with infected pets or farm animals, sharing hair tools, and a weakened immune system also increase the chance of infection and recurrences.
Trichomycosis is treated mainly with systemic antifungal medicines such as griseofulvin, terbinafine, or itraconazole, often for several weeks. Local creams, medicated shampoos, careful shaving or clipping, and hygiene measures help clear the fungus and prevent spread, and early treatment lowers the risk of permanent hair loss.
To prevent trichomycosis, avoid sharing hair and beard tools, wash hands and hair regularly, and treat infected family members and pets promptly. Careful shaving practices, disinfecting grooming equipment, and routine checks in children and high‑risk workers help reduce outbreaks.
You should see a dermatologist for any persistent scaly patches, hair breakage, or inflamed lumps on the scalp or in the beard area, especially if they are spreading or others around you have similar problems. Early diagnosis and lab tests help choose the right antifungal treatment and prevent permanent hair loss or spread to family members.
Trichomycosis is not an emergency, but you should see a dermatologist within a few weeks, or sooner if there is pain, pus, or rapid hair loss. Early treatment reduces the risk of permanent scarring and helps prevent spreading the infection to others.
