My Hubby actually introduced me to these brushes , He uses one on the shower and sometimes one when he styles his hair. They're fabulous detanglers and great for evenly working in a conditioner. Because I have very thick hair , I have to use the brush on small sections but I find it incredibly effective when dealing with a knot (bane of my existence).

These little 'ol' school' brushes are simple yet effective and don't break the bank
