The tip accounts for barely 10 percent of typical tweezers, yet it's the most important part of the instrument. Most come in one of three basic designs -- slanted, pointed and square. Slanted-tip tweezers are ideal for general tweezing. Hair removal specialists, more properly known as estheticians, recommend using slanted-tip tweezers for general eyebrow shaping. Pointed tweezers are better for fine, stubby and ingrown hairs because the ultrafine tips more easily locate and lift the hair. Square tips, with their larger gripping surface, make it possible to tweeze a large area more efficiently, although experts warn that this practice can cause ingrown hairs or scarring.
Another important consideration is the inside surface of the tip, which can be enhanced to increase gripping power. Some tweezers feature a serrated inside surface to increase friction. Others take advantage of diamond dust embedded in the steel. And a few come with gold-plated tips. Twenty-four karat gold, far softer than steel, increases the grip on fine hair.
