I've been on Ortho Tri Cyclen and Yasmin. I am no longer taking either, but I noticed while I was on Yasmin that my hair would fall out more often. I am convinced that Yasmin started the whole thing and I wish I would have never taken it. It's weird because Yasmin seems to be linked to curing hair loss and also causing it, depending on the way your body handles it. Anyway, like I said, I stopped taking the pill a while ago. While I was on it and even after I got off, I realized my hair loss was continuing. A few months ago, I started noticing my hair is noticibly thinning right in the front. I've done a lot of research on this and especially for whoever mentioned irregular periods, you may want to look into this. PCOS or even just insulin resistance is linked to hair loss. There is a lot of information for this on the web. I suggest you look into it. Maybe stop taking the birth control pills and after a few months, go get your blood levels checked to see if you might be either PCOS or IR. If this is the case (or even if your levels come out fine - that happens sometimes), there are options you have to help with the symptoms (such as hair loss). Diet (aimed at keeping your blood sugar, insulin, and testosterone levels in check) and exercise are very important. Anyway, I've just begun this approach and when I stick to it, I'm noticing less hair in the shower drain. I just wanted to share with you something that may be the problem and what may be of help. Good luck.
