Hair thinning shears are scissors that have a sharp razor blade on one side and a blade with teeth on the other. These little teeth grooves are essential to make your hair smooth, cut out uneven chunkiness, remove excess weight, and soften the lines while blending the strands for a smoother finish. These thinning scissors are ideal for salon and professional barbers, hairstylists, and home use and are highly practical and easy to use. They have smooth edges and can be used on men, women, children, babies, and even the elderly.
