Device for increasing hair nutrition

The invention relates to a hair nutrition increasing device which includes a helmet and a steam generator arranged on the outer side of the helmet. The helmet is provided with an optical generator (in slip connection with the helmet) and an optical generator driving mechanism connected to each other. The scalp is irradiated with the light sent out from the optical generator to improve microcirculation, nourish hair follicle and increase hair nutrition. The nutrition supplemented to the scalp is derived from the scalp instead of foreign substances such as hair mask so that the hair nutrition increasing device has better hair nourishing effect and no side effect. Moreover, the optical generator is in a sliding connection with the helmet so that the optical column sent from the optical generator is repeatedly and gradually shifted from the scalp to the hair tip along the hairy root under the action of the optical generator driving mechanism and the difficulty that the hair nutrition is difficultly transported to
