My mother died in 10 months ago. The night before the service i washed my hair and noticed a patch of my hair was gone. It is now 10 months later and no hair has come back, but the patch has not gotten any bigger. what can i do?
See a good doctor to make an assessment of your problem. There are many causes for hair loss and an experienced doctor can give you a diagnosis after a good examination of your hair and scalp.
It’s possible the stress from the loss of your mother caused your loss, and if that is the case I would expect some hair to start growing within a year.
