Could Bald Spot On Head Be Due To Increased Dose Of Chlomid?

I took chlomid for about 6 months, with maybe a month off once. Each time I did not get pregnant, my doctor increased my dosage. In the 6th month, I lost some hair, now I have a bald spot about the size of a quarter. I have stopped chlomid, its been at least 3 months, still bald. Will it ever grow back?
