I began hair shedding Oct 2016, I had a period of stress and have been Having scalp pain, i was diagnosed with mild pcos as I was having few cycles since I was 16 (21 now)and couldn't lose weight but had thick hair until Oct. The shedding seemed Better in late Jan. in Feb i started OCP/Spiro. I've lost 15lbs. Then my hair was shedding againworse than before, my hair seems less thick on one side and has less volume on top, more parts but not wider parts. My endo says it's TE but I'm still worried
