Back in the late 80's during a big time stressful period for me, I had alopecia bad. I had a spot on the top of my head about two inches across and one on the side of my head that was even a little larger. I went to a deramtologist and I got the steroid shots and used Rogaine, which at that time hadn't been approved to be used on women.

I have really fine hair and trust me, I used a ton of hairspray each day to keep my hair styled over it...thank God for big hair in the 80's! I don't remember how long it took to grow back, but it was so scary. Finally the side started growing back very thick. The one of the top took longer and I remember my hair stylist going ahead one day and cutting the rest of my hair on top of my head as short as the new growth.

Good luck and I hope it clears up real soon!
