Nylon bristle is not very expensive. It is good or any texture of hair, but should be avoided on sensitive scalps. It can be safely used on wet hair without causing breakage to the hair, as these resemble natural bristles. Plastic bristles help untangle wet or dry hair without pulling and is generally used during blow-drying as I helps give a smoother look. It is easier to clean such type of brushes.
Mixed bristle is a combination of nylon and natural bristle.
It is excellent for brushing thick hair. It is not recommended for sensitive scalps and except for very fine hair, it is suitable for any hair texture. A vent brush is made of plastic with seven rows of teeth. It is very often known as an airbrush. Vent brush is ideal for brushing wavy or curly hair, permanent waved hair, and thick or coarse hair.
