"My hair is falling like crazy " first post !

Hey girls I'm worried about my hair it's falling like crazy it's never happened before is it that I let grow out up to my mid back or that it's very wavy and I rarely comb it because the waves look gorgeous but anyways I stoped straightening it now. I go to my boyfriends apartment every time he vacuums my hair comes up in a little ball or every time I run my fingers through my hair hair comes out there's never a time that my hair doesn't come out. Please please please any tips it's the first time it's happened has it ever happened to anyone you girls BRW I don't if this helps I'm natural red head I don't if thats some type of thing that happens to us redheads that our hair tends to fall off more I don't know
