Can you loose your hair from birth control?

I've had a thyroid & hormone checked and they were all okay and I am still loose alot of hair.

Hair lose is common in women of different ages for all different reasons. I lose alot of hair normally because I have such thick dense hair but I lost more hair when I was taking birth control and now hardly any whilst I'm pregnant so I think you'll find it is most probably due to the birth control. Mention it next time your at the doctors and increase your grooming.
I think you should see a dermatologist, just in case. I too experienced a little hair loss. Mind you, I wasn't taking care of myself. Take your vitamins change your hair routine, get pharmacy hot oil treatments or go to a salon.
