I am not sure we understand your question.
Do you mean that your roots have locked incredibly close to the scalp? This happened to me (unintentionally) and caused me pain and discomfort.
I am unsure why your hair would break off. Has it been damaged by color/bleach or straightening/curling processes?
If you brush out your locks roughly, you may break many hairs and thus have damaged or broken hairs.
I wish we could offer you more advice- perhaps if you submitted a photo we could have a better idea of what is going on and you can write a better description in the submissions box.
Thanks, and sorry we can’t be more helpful here.
