Boar bristle refers to the stiff, coarse hair obtained from wild boars. It is commonly used in brushes, particularly for hair and grooming products. The natural texture of boar bristles helps distribute oils from the scalp, promoting healthier hair and adding shine. These bristles are favored for their durability and ability to detangle hair without causing static. Brushes made with boar bristles are often recommended for various hair types, as they can help smooth and condition hair while minimizing breakage.
