I started having trichotillomania in the summer of 2020 i pulled out more than half my hair in march 2021, i realized i had to stop when i pulled them out, the bulbs were black and fat i wonder, will my hair grow back? nine months is a short time..?

Hair follicle has three phases: Anagen- continues hair growth for 3-7 years one and half cm every month . Catagen phase - hair loose blood supply, follicle shrinks, bulb does not produce pigment, hair will fall Telegenic phase-resting periods before new hair follicle forms to continue hair growth. Yes they’ll come back if you stop pulling them. I hope it helps.
