I guy I know plucked out his hair transplants before they grew

If you pluck out hairs once, they will grow back, even those that are in the early growth of a hair transplant. If you pluck it out 20 times, likely it will not grow back. I don’t know how many times it takes to reach the threshold when it doesn’t come back. Doctors see patients with trichotillomania, in which some people pick out their hair. This is a real condition and sometimes ties to obsessive-compulsive disorders.
