I was taking Aviane for 9 months - perhaps 9 months too long. I have experienced noticeable weight gain and TREMENDOUS HAIR LOSS. I USED TO have thick, curly hair. I have lost at least 25% of my hair since taking this pill. It is absolutely noticeable - even my hair dresser is shocked. I have checked the other misc prescriptions that I am on - allergies, acid reflux - and this bc pill seems to be the culprit. If you have not started this pill, think twice before doing so. I switched to another 'regular' pill a few weeks ago. I hope my hair grows back!
