Types and uses of hairdressing scissors


1. Density of teeth

Generally, the number of teeth is between 27 and 40 (the most commonly used type). The number of teeth is the percentage of hair that can be cut off when cutting. In other words, a pair of 35 teeth scissors can thin hair by about 35%, and so on.

2. Tooth shape

The shape of the teeth determines the hairstyle structure after trimming. The common teeth are flat, V-shaped and U-shaped. Flat mouth is a relatively early design, because the hair will slide away from the teeth when the scissors open and close, so the thinning ratio is not up to standard. The notches of the V-shaped mouth and the U-shaped mouth have grooves, which can fix the hair proportionally in the notches. The other blade cuts off the hair in the notches, and the hair outside the notches will let it slide away naturally. These two kinds of teeth have many uses, and can be used at the top and bangs to achieve a more natural effect, which can adapt to the requirements of natural pruning method.

3. Width of teeth

In general, the width of the teeth is 1-1.2mnm (fine teeth), and the groove can only hold 1-2 hairs. But for some special designs, the width of the tooth mouth is 3-5mm (thick teeth), the groove position can accommodate 5-10 hairs, and the number of teeth is as low as 7-14. These teeth scissors are specially designed for some special hairstyle structures. The use of coarse teeth scissors can make the top shape of medium and short hairstyles reach a very strong sense of long and short mixed layers.

4. Reverse teeth and bilateral teeth

When holding the scissors with the right hand, the scissors teeth are located on the blade held by the ring finger, and the reverse teeth scissors are just the opposite. The scissors teeth are located on the blade held by the thumb, that is, when the blade is opened, the scissors teeth of the reverse teeth scissors are above and the blade is below. The two cutting edges of the bilateral tooth scissors are both cutting teeth. The main purpose of designing these two kinds of scissors is to reduce the cutting line when thinning hair. For example, take out some layered hair from both sides of the head or the back part of the brain, cut it with the orthodontic teeth, and then pull out the hair. You can find that there is a dotted line at the cutting part, which is formed when the blade is from top to bottom. However, the hair on the lower surface of the blade of the counter toothed scissors will not show a tangent line. Because there is no blade in the bilateral scissors, the upper and lower parts will not show tangent. But because the tooth front collides with each other, it is easy to damage. These two kinds of scissors are most suitable for thinning both sides of short hair style and trimming both sides and back brain position of medium short hair style.
