What type of brush is described as half round with a rubber base?

The type of brush described as half round with a rubber base is known as a classic styling brush. This brush design features bristles that can vary in stiffness, and the rubber base provides a flexible and cushioned area for comfort during use. The half-round shape allows for versatile styling options, making it particularly useful for creating smooth and polished looks, as well as for straightening hair.

In hairstyling, classic styling brushes are ideal for distributing natural oils from the scalp down the hair shaft, which enhances shine and overall hair health. This makes it a crucial tool in both blow-drying techniques and routine styling, as it aids in achieving a finished look without causing excessive damage to the hair.

Other brush types may serve specific purposes, such as teasing brushes designed primarily for creating volume at the roots or grooming brushes that focus on removing tangles and smoothing the hair, but these do not fit the description provided in the question as accurately as the classic styling brush.
