Trichotillomania (Hair Pulling) Support Group
Impulsive control disorder is the inability to resist an urge, temptation, or impulse, even when it may cause negative effects to the self or to others. If you or a loved one suffers from impulsive contorl disorder, join the community to find support and share your challenges with others who know what you're going through.
NEVER make her feel bad about it, she's already doing that to herself. Tell her you love her with or without hair. See if she will talk to you about how she feels when she pulls, why she feels the need to, but ask gently with no judgment in your voice. I know you say shes in counseling but perhaps she doesn't fully trust the councilor to open up.
Did she just start a new school, or is she being bullied? Things that adults could just blow off kids take to heart. Most trichsters are very sensitive to begin with.
