Professional Mini Spa Brush with a blend of nylon ballpoint and 100% boar hair bristles. The unique structure of the boar hair bristles carries the hair�s natural oils from the scalp to the end of the hair shaft. By coating each strand with a very small amount of sebum, the brush repairs dry hair, reduces frizz and adds lustrous shine, while the stiff nylon ball-point bristles massage the scalp, increase the blood circulation and detangle the hair.
