I'm curious to know if your hormones go through any changes when you get into you early to mid twenties and if that would affect your hair. I've always had hair, straight as can be, absolutely NO body. In the past year, it's started getting wavy and sometimes even curly. I like it, and it will help immensely when I have my hair done for my wedding, but I'm just curious if anyone knows what causes these changes. And will birth control have any effect on this? I'm starting the end of March and again, I'm just wondering.
