Yes, I've had this. When I first starting losing my health 3 years ago, long before I even suspected the Mirena, I asked my Dr. about it at an appt., and he looked at my scalp and said it looked rashy.
Using Bosley products for hair loss definitely helps me. My scalp is very healthy, and my hair loss almost stops when I use the products daily. I don't think it makes grow back any faster, but slowing the loss is helpful!
