Ok, so first of all I am 20 years old and having major issues with my usally very thick and vibrant hairt. . Ever since I was a little girl always had people telling me that my hair is super thick and very nice, but just recently in like the past month I have noticed my is falling out. Not in a real alarming rate but fast enought to where I am getting concered now. I have been under a little stress here latley but not enought that I think would cause this. I am a a good eater and drink plenty of water. I take very good care of my hair, very good care. I am just so scared and worried I am going to loose all my hair. I am only 20 years old and worrieda bout loosing my hair. I have noticed my ponytails are alot smaller and my part is not looking right. I am noticing some hair regrowth but not alot. I need some help or advice on what could be going on. Thank you very much!
