Clockwise rubbing is the best way to tighten the roots of dreads.
How to do it:
- grab the dread.
- rub the dread in a clockwise motion against your scalp.
- you can put a rubberband around the root after you are finished to hold the new knots together, make sure the rubberband isn’t to tight just snug.
