I have huge bald patches at the back of my head, my long hair covers them up but if I put my hair up they are quite visible. I also have a bald bit at the front of my hair right where my parting is and I've noticed my hair really falling out a lot recently especially when I wash it and when I brush it I end up with loads of hair in the brush. My doctor took some bloods and I'm very anaemic which could be the cause of it but I'm worried my hair is going to fall out completely
