The best of the both worlds:
Detangling & Smoothing
Detangle & Massage nylon pins in the brush enhance detangle ability, especially efficient on long thick curly hair, while a pure boar bristle cann't do. The smooth rounded tips give the scalp a gentle massage feel which can improve blood circulate and relax scalp muscles.
Distribute Oil & Shine yes, this is the magic of a boar bristle brush. It distributes scalp oil evenly which can prevent greasy scalp but dry ends. After few days of using, shine, softness and health happened to your hair.
