If hair pulling continues over a long period of time, the person suffering from the disorder could experience physical damage.
This could include a permanent loss of hair from the affected regions.
The NHS site recommends seeing your GP if you’re pulling your hair out or if you notice that your child is.

You should also see your GP if you or your child has a habit of eating hair. This can cause hairballs to form in the stomach, leading to serious illness.
Your GP may examine areas where the hair is missing to check that nothing else is causing the hair to come out, such as a skin infection.
