Anything is possible. Ive was diagnosed with Telogen Effluvium from the accutane, then male pattern baldness, then thyroid. So its hard to tell. I have figured out the doctors just want your money, period. Most of the derms I went to were balding anyway. its like they dont give a sh*t. The worst part for me is loosing eyebrows. I was at one time loosing hair from the back and side of my head. Especially my sideburns. That has seem to slow down. all my hair is short now so I cant tell if the ones Ive lost are smaller. I know the diameter has changed dramitically. And the shafts of the lost hair are clear in color, the same with my eyebrows. My endo said this is classic thyroid however the other doctor said It was mbp, im 37 I just want my eyebrows
