Grooming brushes that add polish and shine to the hair have a bristle mixture consisting of _____.

• A. boar and nylon
• B. boar bristle
• C. nylon and nylon
• D. horsehair and nylon

Answer: (A)

Polish and shine come from how a brush both distributes the scalp’s natural oils and glides smoothly through the hair. Boar bristles are natural and help spread sebum from the scalp along the hair shaft, adding natural luster. Nylon bristles provide durability and a firmer brushing surface that helps detangle and create a smoother stroke without snagging. Together, boar and nylon bristles combine oil distribution with a sturdy, even glide, producing a polished, shiny finish that neither material could achieve as effectively on its own.
