Round brushes are ideal for blow drying hair as you get to wrap strands of hair around the bristles, helping to smooth your hair and allow them to dry faster. However, not all round brushes are made the same, and if you use one that pulls and breaks your hair, then youâre not doing your hair any good â just plain damage that adds dryness and frizz. If you want a good quality blow dry, you must invest in a good quality round brush.
