(female) i have bulimia, i used to smoke weed and be very depressed. during that time, i had a v8 moment and suddenly realized my hair was soo much thinner than it used to be. i looked around and realized both of my older sisters, have extremly thin hair, balding hair i guess could describe it more. they have been smoking for tens of years, i have stopped, unfortuantely i have picked up another habit. i guess i want to know what everyone else here wants to know, will or could it grow back? also, i am only 15, im still growing, is there hope?
I would have to see you and understand what you are actually referring to as thinning. I would map out your scalp for miniaturization, perform a hair pull test, and then render an opinion. Obviously without seeing you, I can not really understand what your situation is and where you are in this cycle.
Bulimics often have hair loss from stress and unhealthy weight loss, so I would like to know more about your overall nutrition. I wouldn’t rule out that your hair could regrow at some point, but I doubt it will until you get your eating disorder under control. Hopefully it is a temporary telogen effluvium, but I have no way to know that over the web and without some more medical history.
