A couple years ago, the last year when I was a freshman (I’m a junior now) my hair was super thick and nice, but now it’s kind of thin and gets super oily quickly. I believe it has something to do with me being vegetarian and not paying attention to how much protein (I am eating meat again because I got very sickly) and also stress. I’m working on both of those things, but can anyone give advice? I don’t know if it’s genes because my twin sister’s hair is still really thick and she didn’t go through what I did. Anything is helpful thank you
