I've tried Yaz and three others- all did disastrous things to not only my hair but my body.
My hair got very brittle on all of them. Yaz (BC specifically targeted to help clear skin) made my skin break out like CRAZY. It looked like I was having a freaking allergic reaction... my entire face was red and inflamed. Needless to say, I got taken off of it immediately.

Now I take a natural progesterone cream which eases my heavy periods a bit... I get it from a company called Arbonne, but there are others. I use it according to these guidelines (the PMS or Heavy Period one):

It's cleared up my skin, given me more energy, but unfortunately I'm still having horribly heavy periods, so this time I'm going back to the gyno and demanding an ultrasound.
