What could my sister have if shes getting shorter and losing spike from her eyelashes?

I'm extremely worried. I went to my moms house before and my 16 yr old sister is losing tresses from her eyelashes. I don't mean resembling one or two hairs...i tight like partly of her eyelashes on each side and she seem shorter. It seems close to she lost about three or four inches in plane. What can she have? She's be taken to the doctor here in town and he say there is zilch wrong w/ her. Something has to be going on. What can it be and what can we do?

Help!! 4 yrs ago i have a myomectomy & stage 1 endometriosis surg. & now the very soon they have returned.?

A friend of mine I've agreed for more than four decades
has have the same problem. He only just began losing hair
from his eyebrows sometime. In less than a year, Jay's
eyebrows be completely gone. And he's never been
able to grow them final.
I'm sure there is a dub for the problem, but I do not
know what it is. What I can tell you is that it's a stress
related situation.
I would suggest you go to google.com. Type into their
look into engine: sudden hair loss, or a similar phrase.
That should head you to some imformative sites.
I can also tell you that it isn't something a standard
physician would be able to diagnose. But, at hand are
much more serious problems that a g.p. wouldn't be
able to see.

Good luck.
