Boar brushes:
These brushes feature bristles made of actual hair of a boar. Boar bristles are soft and flexible, so they don’t cause any tears or damage. They also seal off the cuticle of your hair and make your hair shiny. Because they are naturally weak, boar brushes are often mixed with nylon bristles to strengthen its hold on the hair.
This is essential for any straight style. The best brushes are made of boar bristle. It's a natural fibre so hair reacts better to it than to something synthetic. Boar bristle also grips hair better, helps distribute the hair's natural oils and gives a smooth, frizz-free finish. The larger the barrel, the better. Look for a minimum diameter of 60mm.

Styling brush:
If you've got a hairstyle that doesn't require much volume - such as a pixie crop or a bob - try these. The plastic bristles tend to be slightly closer together than those on a paddle brush, meaning they offer slightly more grip, but the smaller head is better for controlling shorter styles.
Vent Brush:
If you have curly hair that has been dried naturally, or with a diffuser, or if you've styled it curly, a bristle brush will leave it fluffy. A vent brush will smooth it through but still leave curls well defined. It's also useful for tidying up curly hair the day after a blow-dry.
Paddle Brush: For Straight Hair:
Paddle brushes usually have bristles coming out of a soft cushion and are great for massaging the scalp, detangling, and smoothing naturally straight hair. The air-filled rubber cushion is designed to bend with your scalp to minimize damage from pulling
