PCOS and hair loss

Hi, I also have pcos. I  am taking 1000 mg.of metformin. also yaz for bithcontro for regular periods. I have male pattern baldness to the point I don"t look at the back or top of my head.  I started out with very thin hair  as it was, alot of fasial hair. happy trail. and alot of extra weight.  My doctor tried all one at a time to see what each do. I also tried cutting carb's to 35 mgs a day. that sucked but lost 15 lbs. then gained 20lbs in one month and 10 2 months after that.  so what I have learned is  50mg. Spironolactone helped the best with my hair loss and all body hair alot. I thinkk the recomended is 200 mg. It makes me very thirsty and have a dry mouth so I have to increase it slow.hope this helps.
