So around sometime last year I found 2 long grey strands of hair, tbh I didnt think much of it and just cut them out, and forgot about it. But today, I seem to have found a cluster of grey hairs and some roots that appear greying. In total, probably around 15 strands of grey hair. I'm surprised as to how I didnt notice them until now as my hair is black and they stand out, but im also now kind of concerned by this sudden onset of more greys. Could this be caused by some hormonal imbalance or something? Bit worried!
