What type of brush should be used for smoothing hair?

The paddle brush is the ideal choice for smoothing hair due to its wide, flat surface that allows it to cover larger sections of hair effectively. This design enables the brush to glide through the hair smoothly, helping to reduce frizz and create a polished finish. The bristles are usually spaced farther apart than those of other brushes, which allows for a gentle, yet efficient, smoothing action without pulling or tugging on the hair.

In contrast, a round brush is typically used for styling and creating volume or curls, making it less suitable specifically for smoothing. A teasing brush is designed for backcombing hair to create lift and volume, thus not effective for achieving a sleek look. Meanwhile, a vent brush has openings that allow air to flow through, making it excellent for drying hair quickly but not for smoothing, as it can create more texture and volume rather than a sleek finish.
