Abstract: A method for producing a clamping member of a hair clip includes filling a plastic material into a cavity defined by a fixed mold and a movable mold, forming a clamping member. The plastic material in rectilinear passages and grooves in the movable mold form teeth on a clamping portion of the clamping member. Then, the movable mold disengages from the fixed mold with the clamping member remaining on the movable mold. Next, the clamping member is moved away from the movable mold by a distance. The plastic material in each groove becomes an elongated section. Before the plastic material completely cures, the clamping member completely disengages from the movable mold. The elongated section of each tooth bends downwards due to gravitational force and completely cures to form a hooked section. The remaining portion of each tooth forms a rectilinear section interconnected between the hooked section and the clamping portion.

Abstract: An improved hair dryer includes a fan unit and a heating unit to generate a linear heated air current which can mix with outside cold air to obtain a rotational air current of moderate temperature and to increase the capability of penetrating a user's hair. Therefore, the air provided by the hair dryer would not become both hot and dry, but maintain an ideal, moderate temperature suitable for users, so that users may feel more comfortable while dressing their hairs. Furthermore, the increased capability of penetrating a user's hair allows the hair to be dried more quickly.

Abstract: A hair dryer includes a main body and an outlet unit. The outlet unit is provided therein with an air-guiding member, which can convert a linearly ongoing air current into a rotationally ongoing air current. Furthermore, the outlet define a plurality of air holes, through which outside air can be drawn into the outlet unit to mix with the air current flowing out of the exit of the main body, to increase air speed, uniformity and penetration and to reduce noise.

Abstract: A loop-shaped hair holding device is made from ingredients including 40 wt % of butadiene, 10 wt % of polyethylene, 3 wt % of polypropylene, 15 wt % of paraffin oil, 12 wt % of styrene, 15 wt % of silicone, 3 wt % of a stabilizer, and 2 wt % of a cross linking agent. The weight of each of the ingredients has a margin of error of 5%. The loop-shaped hair holding device has good surface unctuousness, good toughness, and high elasticity to avoid deformation.

Abstract: A hair clamping device includes a clamping member and a stretching member. The clamping member is a flexible arcuate member including first and second engaging ends releasably engaged with each other. The clamping member is in an extended state when the first and second engaging ends disengage from each other. The clamping member is in a clamping state when the first and second ends engage with each other. The clamping member in the clamping state defines an annular through-hole in a central portion thereof. The stretching member has an outer diameter smaller than a diameter of the through-hole of the clamping member in the clamping state. The stretching member includes an outer surface connected to an inner face of the clamping member. A hair clamping slot is defined between the inner face of the clamping member and the outer surface of the stretching member in the clamping state.
