To cut hair with thinning shears, separate the hair into sections, point the scissors' tip towards the ceiling and cut the hair halfway up each section. Thinning shears are used to give thick hair more of a defined shape. This is done by removing some of the bulk without compromising the style.
Thinning shears look different from regular scissors in that one blade has notches and the other is smooth. This design allows for less hair to be removed than with a traditional pair of styling scissors.
Step 1: Separate hair into sections
Prior to cutting the hair, comb it smooth and separate it into sections. Small hair clips or bobby pins are useful for this step.
Step 2: Thin the hair with the thinning shears
Hold the first section of hair between two fingers of one hand. Point the tip of the thinning shears up towards the ceiling and cut the hair once about 1/3 to 1/2 of the way down from the scalp. Continue around the scalp, repeating this step with each section. If more bulk needs to be removed, repeat the process this time with the scissors pointing down and placed about 1/2 of the way up from the ends of the hair. Brush hair thoroughly to remove the cut hairs.
