Tinea capitis can indeed be contagious to others, as it is a superficial fungal infection that is highly contagious. Transmission of tinea capitis generally occurs through direct or indirect contact, such as during haircuts or sharing personal items. The groups most susceptible to this infection are generally children and adults with lower immune resistance. Therefore, it is crucial to receive prompt treatment for tinea capitis and to use separate towels, bath towels, and washcloths from others.
