A negative ion hairbrush mainly comprises a comb holder and a handle which are folded and pivoted in overlapping manner. The comb holder contains a plurality of flexible or retractable combs and the handle embraces a negative ion generator and a negative ion outlet at the pivot joint directing the anion energy from the generator flowing toward the combs when the comb holder and the handle are in opening position. While the comb holder and the handle are in folded position, the negative ion outlet is exposed and the anion energy continues flowing outward so the negative ion hairbrush is used as the hairbrush and as the air purifier. When used as a hairbrush, the negative ion energy will neutralize the cation charge to prevent the hair cell from decaying and the hair from falling off.
