If your hair brush continually snags your hair, you may want to consider a wide-tooth comb or invest in a brush with wider-spaced bristles. By continually using it, you will end up pulling out hair causing hair loss and damage to the roots. A brush should slide through easily, act as a detangler, and remove dead skin cells to keep hair healthy.  If the brush is snagging, this indicates that you do not have the best brush for your hair. You may end up causing hair damage.
