How is this different from a diffuser?

A diffuser spreads air over a bowl to dry curls gently. This brush pushes air through vents while its bristles shape curls and lift roots, giving more control but less even, gentle drying.

Can I use it on dry hair?

It is best on damp hair with a dryer on low heat and low speed. On dry hair the bristles can pull curl clumps apart and cause frizz.

What curl types does it suit?

It works best on wavy to medium curls, roughly 2B to 3C. Tight coils are usually better served by a diffuser or a wide-tooth comb.

Does it work without a blow dryer?

Yes, as a detangling and shaping brush on damp hair, but the vents only help when air is blown through them.

What should I check before buying?

Look at bristle spacing and tip softness, and whether the vents run through the full head. Flexible, rounded tips are less likely to scratch the scalp.
