Hi could anyone enlighten me, do you gain weight, have low libido erractic menstrual cycles,and fatigue with alopecia.because I am certainly sure you don't. because I have all these and my doctors fob me off saying its alopecia. me personaly think it is hypothyroid, or possibly coming off the contraceptive pill 3 years ago and hormonal.this is when I started to lose my hair. I still have hair but its like a patch work quilt underneath.it  started to get better not sure if it was the evening primrose sea kelp or vit b12. I know hypothyroid is not detected from blood work, and I know your hormones fluctuate, it is so frustrating to know the actual cause. what do hair biopsys pick up does anyone know.? x
