scalp picking a way to stop

I am a 17 year old guy who experienced this dilemma when i was 14. It all started when i was scratching my head and this scab was stuck to my hair and i could feel it with my fingers, so i took it out and examined it and tasted it and after that it became a habbit but i know a way to stop it. The best thing to do is to keep urself busy,trust me it helps a lot. Secondly if u are a guy get spikes and apply gel or other hair products,this will help you because u will not tend to eat ur scalp if u have gel on it and plus it will ruin ur spikes! Thirdly do not spend time alone as this will only encourage u to pick ur scalp. Hope this helps. It helped me...
