VEGA PROFESSIONAL Flexi brush made from boar bristle and flexible nylon is recommended for fine and medium hair textures and for sensitive scalps. The Flexi Brush bends and flexes to perfectly meet the contours of your scalp and boar bristles benefit those with scalp and hair problems like itching, split ends, hair loss and help in distributing the natural oil from scalp through the lengths of the hair, adding shine and texture. The anti-static ionic brush gently exfoliates scalp and minimizes flakes, itch and dandruff. The bristles also stimulate the hair follicles for stronger and healthier growth.
