Oh my god . I am having a very similar problem . I ' ve already had really thick hair and I normally wash every other day to every couple days , but suddenly I ' m losing sooooo much hair when I shower . It terrifies me . But , I think the cause of my was a bleach treatment I had done on my hair a few weeks . I ' ve never bleached my hair in my whole life and I ' ve also never had hair loss like this . So I feel certain that ' s the cause . My husband , on the other hand , feels positive its stress related because stress levels have been borderline anxiety attack lately . Or maybe it ' s a combo of a both . I don ' t really have a whole lot of advice here , but I wanted to let you know yoj aren ' t only one panicking at the sight of handfuls of a full strabd hair coming out in the shower .
