What Causes Falling Of Hairs From Eyebrows Despite Using Anti Fungal Creams?

HI, I have been dealing with flaky itchy eyebrows for the past 2 weeks now, I itched for a little, and the Flakyness became much worse. I went to see a doctor and I was prescribed Lamisil antifungal cream 1% and Hydrocortisone 1 %. So the itchyness pretty much went away and the flakyness is still there a little bit. My main concern is that my eyebrows(inner part ) only have been falling out everyday. I lose about 3-4 eyebrows a day. They have become pretty thin from the inside. Can you please Help ???
