You hair falls out in cycles. Any type of stress can make your hair fall out. This is call telogen effluvium. I have hypothyroidism and my hair has gone through this many times when I have been low. I also went through this with my 3 pregnancies, gastric bypass and now lap band. Here is what you need to do:
Take about 1000th of Biotin
Take 500mg (2x's a day) of Evening Primrose Oil
Make sure you are getting your Protein in.
Take your B12, b6,and b5
B Vitamins are essential for your hair.
I am not a doctor or nurse, but I havev researched this subject because of my situation.
If you have anymore questions, just ask.
