Trichomycosis axillaris is a bacterial condition of the hair, and proper diagnosis is important before starting any treatment. Benzoyl peroxide-based washes like Benzonix Gel Wash may help reduce bacterial load and improve hygiene, but they may not fully treat the condition in all cases, and the response can vary. It is important to consult a doctor or dermatologist for a proper medical evaluation, as similar symptoms can occur in fungal infections or other skin conditions. A doctor can confirm the diagnosis and recommend an appropriate treatment plan, which may include topical antibiotics or other specific medications if required.
