A hair clamp has an outer shell comprised of a thin substantially rigid plastic material The shell includes a front portion and a rear portion each of which is separately hinged to a spine portion. The inner surface of the shell is covered with a layer of foam material which is bonded to the spine portion. The shell and the foam material are foldable about the hinges to form a clamp having front and back halves with the foam material in the inside thereof. A lock integral with the plastic shell is adapted to maintain the clamp in its closed position. The outer configuration of the hair clamp is substantially rectangular. However, the bottom of the device is somewhat concavely curved while the top is convexly curved. This allows the device to be placed close to the person's head since the bottom fits the contour of the head. The hair clamps can also be stacked vertically one on top of the other for longer hair.

An ergonomically designed toothbrush includes a handle of rectangular cross-sectional configuration. The handle is twisted about its longitudinal axis so that it fits the palm of a person's hand providing a power grip yet will fit most toothbrush holders. The forward end of the handle tapers outwardly and has an elliptical cross-sectional configuration with its outer surface being textured for ease of manipulation and comfort. A small elliptical neck connects the brush head to the handle and is designed not to interfere with the lips or cheeks when brushing. The brush head includes multi-level tufts of two grades of stiffness arranged in offset rows and is designed to remove plaque from interproximal areas as well as tooth surfaces and to reach into the gingival margin to gently massage the gums.

A hair clamp has an outer shell comprised of a substantially rigid sheet-like material such as cardboard or the like. The surfaces of the cardboard are preferably coated with a water-repellent material. The inner surface of the shell is also covered with a quarter-inch layer of foam material. The shell and the foam liner are then folded over upon themselves along a midportion thereof to form a clamp having front and back halves with the foam liner in the inside thereof. A U-shaped plastic clamp or a plastic coated wire twist device can be used to maintain the hair clamp in its closed position. The outer configuration of the hair clamp is substantially rectangular. However, the bottom of the device is somewhat concavely curved while the top is convexly curved. This allows the device to be placed close to the person's head since the bottom fits the contour of the head. The hair clamps can also be stacked vertically one on top of the other for longer hair.
