Hair changes?!?

Has anyone experienced a change in hair texture after being on the pill? My hair on my head has a completely different texture. Like, I used to have wavy super textured frizzy hair and now my hair is rather straight and gets oily a lot easier. Also, my body hair isn't growing very much and is very fine. Like I have to shave once a week instead of once a day. I haven't changed anything about my daily routine or diet, I just started the pill about 2 months ago and that was around the time my hair has started being weird.
