I was on Estrostep FE (another triphashic pill) and I lost at least a quarter of my hair. It started probably right from the beginning, but it was gradual and I had always had very thick hair so I didn't notice any major loss right away. I was on it for two years, way too long, I wished I would've went off it sooner. I wouldn't mess around with something like that, I'd switch to another pill asap because it probably won't get any better. You might try a monophasic pill instead like Ovcon-35.
