Natural boar-bristle hairbrushes have bristles made from the hair of the adult boar. If you look at these bristles with a magnifying glass, you can see that each bristle is scaly rather than smooth in texture; this helps remove dirt from the hair shaft and distribute the follicles' moisturizing sebum from the scalp to the hairs' ends. Thin hair, medium hair, straight hair, and wavy hair are all well suited to natural boar-bristle brushes.
Boar bristle brushes come in the traditional paddle, rounded, and half-rounded styles. Take care of them and they'll last decades.
Synthetic brushes
Nylon bristles do a good job of massaging the scalp. However, because the individual bristles are smoother than natural boar bristles, they do a poor job of cleaning the hair shaft and distributing moisturizing sebum along the hair shaft. Still people with very thick or very curly hair may find a pure boar-bristle brush, to be too soft to penetrate their hair, making nylon bristles a good choich. Choose a brush with rounded ends that won't scratch the scalp, Some nylon brushes feature a metal base that retains heat during blow?drying; this helps the brush act as a freestyle hot roller.
Like natural boar-bristle brushes, nylon bristle brushes come in the traditional paddle, rounded, and half-rounded styles.
Boar-synthetic bristle combination brushes feature a mix of natural boar bristles and nylon bristles. The combination of bristles makes these brushes ideal for anyone with thick or curly hair who needs the stiffness of a nylon bristle, but who wants the shaft-cleaning and moisture-distributing ability boar bristles. Combination brushes are most popular in paddle styles, but can be found in round and half-round shapes.
The vent brush features inflexible plastic or rubber bristles imbedded in a vented base. It does not massage the scalp, help remove dirt, or distribute sebum; this type of brush is for styling only, and is often used during blow-drying. Because vent brushes can snag and pull hair, I don't recommend them.
