Ringworm is a contagious condition primarily affecting children and mostly localized on the scalp
. It is the result of a microscopic fungal infection, or mycosis
, and represents one of the dermatophytosis conditions. Ringworm is characterized by progressive hair loss
and the appearance of patches of yellow or red patches with desquamation
) of the scalp. These patches are topped with crusts, and the affected hairs become highly fragile. There are several different types of ringworm depending on the fungus responsible, almost all represented by the Trichophyton and Microsporum fungal species. There is a molecule that can eradicate these fungal infections, called an antifungal
agent, which is applied to the scalp in the form of shampoo.
