Thanks x your answer Joe, yes it was diagnosed by many dermatologist few years ago...
It's just back this summer,6 months after my hair transplant. My diet it's really good and I Do a lot of excercise, Thought I shouldn't scrub my scalp. I really hope I will get them back too. How long should it take to see some improvement? Some says 3 to 4 months but I couldn't see any. Did yours were transplanted hair? .
Tanks so much, all the best...
