The hair volumizing device of the present invention provides a “bump” in the hair that is a desired style by many. The hair volumizing device comprises a body member and a securing mechanism to secure the body member to the hair. The body member has a first end, a second end and one or more sides and is made from or covered with a material that helps keep the user's hair in place over the hair volumizing device. In the preferred embodiment, the securing mechanism is attached to or made integral with the bottom side of the body member. A preferred securing mechanism is configured and utilized in a manner similar to commonly available barrettes.
