In today’s fierce market competition, the importance of franchise strategy for the development of hairdressing companies has become increasingly prominent. Below I will introduce to you the basic knowledge of hairdressing, I hope it will be useful to you!

Basic knowledge of hairdressing: Trimming contours

Trimming contours is the first step in hairdressing. Usually, the hair is combed smoothly first, then divided into sections according to the hair style requirements, and each area is clamped with large hairpins, and then trimmed step by step. Usually starting from the nape of the neck, cutting to the sides and top of the head, and finally trimming the hair on the forehead.

When trimming the hair on the back of the neck and both sides, first cut a flush standard line, then lay down the hair at the back in layers from bottom to top, and cut it flush with the standard line. And trim the hair on both sides in the same way. When trimming the top hair, comb all the top hair down to all sides, and then cut it according to the outline of the hair style. Finally, pick out a part of the hair on the forehead to form an inverted triangle shape, and trim the width of the bangs according to the hair style requirements to complete the trimming of the entire outline.

Basic knowledge of hairdressing: Adjusting the layered cutting method

1. Picking

Picking is to lift a piece of hair with a comb , according to the requirements of the hairstyle, pick a certain length and cut off the excess hair. This is the pruning method that works best with scissors and a wooden comb. The scissors and comb should be closely combined when picking. Use the comb to pick up a strand of hair and use scissors to cut off the excessively long hair exposed outside the comb teeth. Comb the comb and use the comb to guide the hair. When cutting hair, the stationary blade of the scissors should be kept parallel to the back of the comb, so that it is easier to cut evenly. When pruning, pay attention to keeping the segments fine and even to avoid disjoints or excessive density. When pruning upward, push and cut forward in different directions according to the needs of each part to solve the step difference and modification density.

In addition, when picking and cutting, you must correctly grasp the angle at which you lift your hair. Generally speaking, if the angle of raising the hair is large, the level will be high, and if the angle of raising the hair is small, the level will be low. The lifted hair should fit into the curved contours of the head. When cutting, you should cut according to the curved outline of the head. Do not cut straight, as this will easily cut corners. You should not cut too much hair, and you should pay attention to the connection of the upper, lower, and front hair, and there should be no disconnection.

2. Sawing

Sawing is a technique of cutting hair using serrated scissors. The blade of serrated scissors is in a zigzag shape, resulting in uneven hair ends and reduced hair volume. Saw cuts are usually used to trim the hair contours to give the entire hairstyle an elegant look.

The main purpose of sawing is to keep the scissors and the hair cutting diagonally upward or downward. It cannot be cut parallel, but should be cut diagonally, so as not to overlap and affect the hair layer. The location of the saw teeth should be considered in advance and be aware of it. Generally speaking, parts with thick hair should be cut more, and parts with less hair, especially short hair and the sides of the head, should be cut less.

3. Clamping

Clamping is a very frequently used technique in which hair is clipped with fingers for trimming. It is characterized by easy operation. When clipping and cutting, first use a comb to distribute the pieces in order to comb the hair vertically or horizontally. Clamp the combed hair with the middle and index fingers of your left hand. Straighten it with the wooden comb at right angles to the hair roots. Comb it until the hair style is desired. Slowly cut along the back or palm of your hand to the required length. Cutting along the back of the hand is called an external pinch cut, and cutting along the palm of the hand is called an inside pinch cut.

When clipping and cutting, pay attention to the straightness of each strand of hair and the connection between each strand of hair, that is, pay attention to the angle of each strand of hair to avoid disconnection.

To understand the relationship between hair cutting angle and layers. Layers refer to the orderly arrangement of hair with a certain slope at the tips. It is an important part of the hairstyle structure. The angle of hair trimming is closely related to the layering. Generally, parallel slicing and shearing form a low level or one level (also called no level or stacked levels), while vertical slicing and shearing form a high level. Different parts are trimmed at different angles to form different levels.

If the top hair is trimmed vertically and horizontally, the layer will be moderate; if it is trimmed upward, it will form a low layer, and if it is trimmed downward, it will form a high layer. Cut the side hair vertically into sections, at a 90° angle, for a moderate level; cut at a 45° angle upwards, to create high levels; cut at a 45° angle, for low or overlapping levels. level.

4. Catch-cutting

Catch-cutting is a technique in which a comb is used to comb a strand of hair, and then the fingers are used to grab the hair and trim it. It is different from clipping scissors. The hair clipped by clipping scissors is usually in a bunch, with a larger base and a slightly pointed shape. Snap shears are usually used to trim hair on the top and sides.

In grabbing and cutting, grab the width of the base of the hair to determine the size of the arc formed after the hair is cut. Generally, if the base of the hair is large, the curvature will be large after cutting. On the contrary, if the base is small, the curvature will be small after cutting. When grabbing and shearing, different parts of the shear form different arcs. Different directions of grabbing the hair upward, backward, and forward will also produce different arcs. During grabbing and cutting, the position where the scissors drop after grabbing the hair should be moderate, not too high or too low, as this will affect the length and curvature of the hair.

5. Cutting

Cutting is a cutting method in which a sharpener or scissors slide quickly on the hair to cut off the hair. After cutting, the tip of the hair will be in the shape of a pen tip, giving it a sense of lightness and movement. Cutting is often used to repair layers, contours and thin hair.

When cutting hair with scissors, the blades of the scissors should be slightly open. Place the hair clamped between your fingers between the two blades. The blades are slightly beveled. Use the blade to slide on the hair to cut (cut) the hair. Break. Use appropriate wrist force when cutting. If the cutter is too heavy, too much hair will be cut off; if it is too small, the hair will not be cut off. When cutting, hold the hair between your fingers and maintain a certain tension to facilitate cutting off the hair. When cutting, you need to control the extent of the scissors blade sliding on the hair. Generally speaking, the larger the angle, the smaller the shape of the tip, and the smaller the angle, the larger the shape of the tip.

When using a razor to cut, pay attention to the angle between the razor and the hair. Generally, the angle is between 20 and 45 degrees. A large angle will cause the tip to be small. If the angle is small, the tip will be large. If the angle is too small, the hair will be damaged. It is easy to curl up and damage the hair. The sliding range of the razor on the hair determines how much hair is cut off and the level of layers. The larger the sliding range of the razor, the more hair will be cut off, and the resulting layer will be higher; the smaller the sliding range of the razor will, the less hair will be removed, and the resulting layer will be lower.

6. Back-up scissors

Back-up scissors are a basic cutting method that uses your fingers or a comb to hold the scissors for pruning. It is generally used to trim forehead hair, temple hair and hair around the ears.

7. Knife-point scissors

Knife-tip scissors are a basic technique for cutting hair with the tip of scissors. The method is to comb a strand of hair with a comb, hold it with your fingers, and then trim it vertically or slightly from top to bottom with scissors. Gives hair tips a natural jagged and light feel.

Tips: Correct law enforcement of scissors

Put the thumb and ring finger of your right hand into the rings of the movable and fixed handles of the scissors respectively, and hold the scissors, index finger and middle finger Place it on the handle of the knife without a handle, and hang your little finger on the handle behind the handle to stabilize the blade. When cutting hair, the thumb swings the movable handle, while the other four fingers stabilize the blade.
