24 yr old f. recently diagnosed with alopecia. it keeps spreading and finding more patches. is there a way to slow down spreading? it also itches.

R/o fungal infection: Sounds like alopecia areata, but with itching, I'd get a fungal culture from the areas to rule out a fungus infection as cause. sometimes even without itch, spots that look just like alopecia areata can be caused by a fungus, which would be treated with oral antifungal +/- medicated shampoo and topical anti-fungal. Alopecia areata that is spreading quickly often treated with systemic steroid.
