The invention relates to a health-care comb with movably-used comb teeth. According to the adopted technical scheme, a comb frame is thorough, a hard rubber base is arranged in the comb frame, and the comb teeth are inserted into the hard rubber base in a penetrating mode and can be switched on the hard rubber base in a left-right mode. For keeping the designed height after comb tooth switching, a comb tooth limiting insert plate is arranged on the comb frame, and sliding teeth are arranged on the three sides of the comb tooth limiting insert plate and are matched with sliding grooves formed in the corresponding positions of the inner side of the comb frame. When intertwined hair is needed to be removed, the comb tooth limiting insert plate is pulled open, then the comb teeth are pressed down by using the comb tooth limiting insert plate or fingers, the intertwined hair is easily removed, the comb tooth limiting insert plate is inserted well, the comb teeth penetrate through the other side and are fixed, and the very clean other side of the comb is shown. When intertwined hair is needed to be removed again, removal can be achieved by repeating the operations. The health-care comb has the advantages of quickly removing intertwined hair and being convenient to use.
