Anti-dripping hair and body shampoo comprises a liquid outflow device, an anti-dripping device and a liquid bottle; the liquid outflow device comprises a pressing head and a liquid outflow pump; the pressing head comprises a spraying head and a liquid feeding connector; the anti-dripping device comprises a piston cylinder, a piston, a sealing plug, a spring and a driving piece; in use, the pressing head of the liquid outflow device is pressed down, then releasing is performed, and the pressing head is made to automatically rise; a liquid feeding driving pipe is used for driving the liquid outflow pump so that hair and body shampoo liquid in the liquid bottle can be pumped to a liquid outflow channel of the spraying head; meanwhile, the driving piece is used for overcoming the elastic forceof the spring to drive the sealing plug to move, and a liquid outflow hole of the spraying head is opened, so that the liquid shampoo is sprayed out of the liquid outflow hole; after the liquid is sprayed out of the liquid outflow hole, the sealing plug restores under the effects of the elastic force of the spring, the sealing plug is inserted into the liquid outflow hole, and the liquid drippingand leaking problem is solved; and after the liquid in the liquid bottle is used up, the used liquid feeding driving pipe is connected with a liquid outflow pump on a new liquid bottle, the pressinghead of the liquid outflow device and the anti-dripping device are reused, circulation is ceaselessly performed in this way, and waste of resources is reduced.
