Abstract
Description
[0001] Alexander Khachaturyan's haircut
[0002] Field of technology
[0003] The claimed invention relates to the field of hairdressing, more specifically to the technique of cutting human hair and can be used when cutting hair of any length.
[0004] State of the art
[0005] Hair cutting is one of the most challenging jobs in hairdressing, as it determines the shape of the hairstyle, the texture of the hair, and the length of time the desired style will last.
[0006] A prior art hair cutting method using directionality (KR 20200009688, January 30, 2020) is known. The method involves dividing the haircut into eight directions, including various methods such as moving forward diagonally up and down. Based on the hair's shape line falling downward under the force of gravity, it is divided into zones according to guides, and the cutting direction in which the design is made is analyzed. The shape of the head's weight line is also checked (using a triangle, square, or circle to determine the direction in which the cut is made). The hair cutting method using the directionality of the present invention can recognize the orientation of the shape line along which the hair falls during cutting using directionality, can quickly cut hair using the head shape, directionality, and two sections, can be easily mastered by unskilled people, and can create various hairstyles according to the client's wishes.
[0007] Also known is a method for cutting the scalp hair (RU Patent No. 2786459, IPC A45D 24 / 00, published 21.12.2022), comprising the step of combing the scalp hair, the step of dividing the scalp hair into zones, the number of which is determined based on the shape of the head and the haircut, the step of alternately dividing the scalp hair of a separate zone into strands formed by subzones having the shape of a quadrangle, wherein the number of subzones is determined by the shape of the head and the haircut, as well as the density of the scalp, a cutting step, in which a series of successive cuts are performed, wherein each cut in the series describes a quarter of a circle and a cut is made along the entire thickness of the scissor blade, and is completed in a position parallel to the scalp, so that the blade of the scissor is directed with the tip towards the head, the number of cuts is determined by the density of the scalp.
[0008] A drawback of known methods is the inability to create a visually natural, "natural" haircut with a smooth cut in the direction of hair growth, which would promote better distribution of volume and texture. Furthermore, it is impossible to achieve a wide variety of results.
[0009] The essence of the invention
[0010] One of the advantages of this method is that it requires no tools other than standard scissors. This technique achieves the same effect as a straight razor, clippers, or other types of scissors. Moreover, this technique is the most convenient and mitigates the disadvantages associated with the tools mentioned above.
[0011] Cutting hair using only scissors is preferable due to a number of technical advantages. These include the ability to create a more natural look through more precise control over hair length and texture, as well as a personalized approach to styling each client's unique features. Furthermore, cutting with scissors is gentler on hair, reducing the risk of damage, and can be used on dry, already damaged hair. Furthermore, this method offers more room for creativity and experimentation with different styles, and delivers a longer-lasting result that retains its shape and structure longer than using clippers or a razor.
[0012] The technical objective of the invention is to create a proper hair cut, which improves hair quality, volume distribution, and the longevity of the hairstyle. An additional technical objective is to speed up the haircutting process.
[0013] The technical result of the claimed solution is an improved cut quality, which affects hair quality and allows the haircut's shape to be maintained for a long time after cutting. This technical result is achieved by cutting clean, dry hair in its natural free fall, and involves the following steps:
[0014] - determine the hair length and haircut shape with the client;
[0015] - wash hair using cosmetic products;
[0016] - dry your hair using a hair dryer, drying the hair to 75-85%;
[0017] - the hair is divided into 4 zones: the lower occipital zone (1), the temporal and upper occipital zone (2), the parietal zone (3), the bangs zone (4).
[0018] - a haircut is formed by cutting the hair with scissors in each zone, while the cutting process includes the following steps:
[0019] - a strand of hair is formed in the selected area, while the strand is visually distinguished from the general hair sheet and remains in a free state, and the width of the strand depends on the hair length and haircut shape chosen by the client;
[0020] - determine the angle of inclination of the scissors in relation to the given strand to perform the cut, while the angle of inclination of the scissors depends on the degree of hair elongation in accordance with the hair length and haircut shape chosen by the client;
[0021] - determine the texture of the cuts for a given strand depending on the hair length and haircut shape chosen by the client;
[0022] - determine the working part of the scissors blade depending on the hair length and haircut style chosen by the client;
[0023] - cuts are made along the hair growth of a given strand using the selected scissor angle, with the scissor movement determined by the selected texture and the working portion of the scissor blade. In some embodiments of the cutting method, which involves hair in its natural free fall, the method includes the following steps:
[0024] - determine the hair length and haircut shape with the client;
[0025] - wash hair using cosmetic products;
[0026] - dry your hair using a hair dryer, drying the hair to 75-85%;
[0027] - the hair is divided into 4 zones: the lower occipital zone (1), the temporal and upper occipital zone (2), the parietal zone (3), the bangs zone (4).
[0028] - a haircut is formed by cutting the hair with scissors in each zone, while the cutting process includes the following steps:
[0029] - a strand of hair is formed in the selected area, while the strand is visually visible against the background of the general hair and lies in a free state, and the width of the strand depends on the hair length and haircut shape chosen by the client;
[0030] - determine the angle of inclination of the scissors in relation to the given strand to perform the cut, while the angle of inclination of the scissors depends on the degree of hair elongation in accordance with the hair length and haircut shape chosen by the client;
[0031] - determine the texture of the cuts for a given strand depending on the hair length and haircut shape chosen by the client;

[0053] Detailed description of the technical solution
[0054] The claimed technical result is achieved by implementing the method according to the present invention, in which three main blocks can be distinguished:
[0055] 1) Hair preparation;
[0056] 2) Dividing hair into zones;
[0057] 3) Hair cutting.
[0058] First of all, together with the client, we determine the expressive features or relief of the line of the desired hair distribution and discuss the design and shape of the haircut with the client.
[0059] Block 1 - Hair Preparation
[0060] The hair cutting method according to the present invention is carried out on clean hair that is 75-85% dry and in a natural free fall.
[0061] In some embodiments of the present invention, the hair may be pre-washed with shampoo, conditioner, and hair mask and dried using known techniques using a hair dryer. This hair preparation allows the natural features and character of the scalp to be revealed and visible: 1) natural hair volume; 2) hair texture; 3) hair density in different areas; 4) hair growth direction (straight, swirl, converging, cross-shaped, etc.); 5) parotid hair volume; 6) hairline curves.
[0062] The cutting method according to the present invention, as described above, is performed on hair that is 75-85% dry. This allows for the determination and control of texture, volume, and strand thickness to manage the natural characteristics of the hair and its format. It should be noted that these characteristics cannot be seen on wet hair. Determining hair density, volume, and growth allows for a balance of volume and texture. This, in turn, allows for easy styling, with hair that lies comfortably and naturally. The hair will lie according to its proper, natural distribution into strands and layers.
[0063] Prep allows for proper sectioning of the scalp, taking into account the direction of hair growth on sections (temples, crown, bangs) and the angle of hair growth from the root. The natural root volume after drying allows for precise hair length definition. This approach to prepping the hair during initial drying eliminates the need for subsequent finishing.
[0064] These natural, organic features and characteristics of hair are revealed and become apparent precisely through drying, which is impossible to achieve and see on wet hair.
[0065] Hair is dried to 75-85%, meaning it's not completely dry but remains slightly damp. The hairdresser assesses the degree of dryness based on tactile sensation. This level of dryness helps prevent overdrying, dehydration, and excessive frizz, among other things.
[0066] In some non-limiting embodiments of this method, hair drying is performed with the application of heat protection and various styling products. In some embodiments of this method, drying is performed using a hair dryer at medium temperature and medium power.
[0067] In some non-limiting variations of this method, drying is performed by hand or with a diffuser along the hair growth from top to bottom, without changing the direction of hair growth, with maximum use of natural characteristics (skull shape, hair growth pattern, hair texture); for convenience, a comb can be used.
[0068] Block 2 - Dividing hair into zones.
[0069] With reference to Fig. 1, in the present embodiment of the method according to the present invention, 4 zones are distinguished:
[0070] - lower occipital zone (1);
[0071] - temporal and upper occipital zone (2);
[0072] - parietal zone (3);
[0073] - bangs area (4).
[0074] This division of 4 zones allows for a balanced and even division of the entire hair volume.
[0075] In some non-limiting embodiments of this method, the fringe zone (4) may not be separated from the crown zone (3). In this case, the hairdresser will work in three zones, three zones instead of four. This technique can be used, for example, when working with short hair.
[0076] One of the advantages of the present invention is that there is no need to divide into smaller zones and the ability to work on large areas of the head.
[0077] Block 3 - Hair cutting.
[0078] At the next stage, the hairdresser performs the haircut by cutting the hair with scissors in each zone.
[0079] In this block, we can also highlight several main steps.
[0080] In the first step, the first strand is formed during the first zone treatment. Fingers grasp the first strand from the first zone, pinch it on both sides, and separate it from the rest of the hair. The strand falls freely in its natural position, visually standing out from the rest of the hair as shown schematically in Fig. 2.
[0081] Fig. 3 schematically shows the strands belonging to the temporal and upper occipital zones (2). In each zone, all strands will be processed in this way in turn.
[0082] The width of the strand varies between 1-3 cm, and is chosen based on the shape of the future haircut. This parameter allows you to shape the texture of the haircut.
[0083] A strand 1-1.5 cm wide. Choosing these strands creates a soft, smooth, and polished texture. The narrow width of the strands creates a smooth, polished effect.
[0084] A 1.5 - 2 cm wide strand is selected to create a more textured, but still soft, texture to the haircut.
[0085] A strand 2-3 cm wide should be chosen to create textured haircuts.
[0086] In the second step, the cutting angle is determined.
[0087] Each strand in each zone is cut in accordance with the selected angle of inclination of the scissors in relation to the hair, and the angle of inclination of the scissors depends on the degree of elongation of the hair in comparison with adjacent strands, where the degree of elongation is determined by the chosen haircut design.
[0088] As stated above, a strand of hair from any area is in a natural position, that is, it falls freely downwards and is considered as a straight line, relative to which angles of varying sizes are formed with scissors.
[0089] Fig. 4 shows a free-falling strand, and the lines directed toward it indicate the position of the scissors relative to the selected strand (hair), with the 0° line in Fig. 4 representing the strand itself. The angles formed between the strand (0°) and the cutting surface of the scissors are indicated in degrees. The effect produced by cutting a strand at the selected angle without pulling the strand is expressed in the type of cut obtained (from diagonal to straight) and the density of the final cut (from less dense to very dense). Thus, the choice of the position of the scissors and, accordingly, the angle between the strand and the scissors is determined by the objectives of the haircut. It is important to note that the angle is always formed relative to the hair, and not relative to the floor, head, or other possible reference points, as shown in Fig. 5.
[0090] The hair is cut from top to bottom along the hair growth using the selected angle of inclination of the scissors.
[0091] The minimum angle between the strand and the scissors is 5°. This angle allows for a long diagonal cut. As the scissors are positioned and the angle between them and the strand increases, the resulting cut changes from diagonal to straight. Cutting the hair at a 90° angle allows for a straight cut. Thus, moving from the minimum angle of 5° to 90° allows for the resulting cut to be adjusted in type and length: from a long diagonal to a straight cut. This makes choosing angles within this range suitable for creating layers and graduated haircuts.
[0092] This special type of cut, along the hair growth along the entire length of the free-flowing strand, allows you to adjust the density of the finished cut depending on the needs of the haircut. This creates clean lines in haircuts and is also helpful for creating graduated haircuts. This method ensures optimal results and long-lasting satisfaction from styling and care, creating voluminous and textured hairstyles with varying levels of gradation and layering.
[0093] Selecting the correct scissor angle plays a key role in creating the perfect hairstyle, as it allows the hairdresser to precisely control the shape and volume of the hair during the cutting process. The method according to the present invention, thanks to its unique cut, eliminates the drawbacks of the prior art haircutting method using strand extensions, in which, after the strand is cut, it behaves unpredictably and returns to its natural shape, disrupting the shape of the future haircut. Thus, choosing the correct scissor angle becomes an essential tool for achieving the perfect haircut, ensuring a more professional and personalized approach to each client.
[0094] In the third step, the texture is determined.
[0095] Haircut textures can vary: from voluminous and fluffy to light and airy, from layered and textured to straight and uniform. Various cutting and styling techniques allow you to create a variety of textured effects that add volume, texture, and a unique look to your hairstyle. Haircut texture plays a vital role in creating a hairstyle.
[0096] In addition to the angle, the direction of the scissors during the cut also influences the quality of the resulting haircut. Scissors can move in various ways, for example, rotating around their axis, stopping, etc. The direction of the scissors' movement depends on the chosen texture, which is determined by the hairdresser for each strand or group of strands, depending on the desired hairstyle.
[0097] Depending on the desired shape of the future hairstyle, a texture is determined for each strand.
[0098] With reference to Fig. 6, in some non-limiting embodiments of the present method, the following types of textures are distinguished:
[0099] A diagonal texture (Fig. 6a) is a texture in which the angle is directed to the right or left. When texturing hair, the technician moves in a specific direction at an angle. This texture is used to control the hair's natural movement. For example, a natural curl can be pushed in a different direction, loosened and made less curly or even straight, or, conversely, curled more. Similarly, with straight hair, this texture can be used to create a wavy or curly look.
[0100] Checkerboard texture (Fig. 6 b) - when cutting a strand, the scissors move from top to bottom, making "stops" and moving to the next section of hair in the same strand. When working with the next strand, it will be cut not from the same point from which the previous one was cut, but from the point where the stops were made. This method helps achieve volume, a maximally airy, careless texture, with individual strands and ends highlighted. However, it is important to still observe some order and pattern in the haircut. Alternating long and short strands. Cascade texture (Fig. 6 c) - this texture is similar to the previous one. When cutting a strand, the scissors move from top to bottom, making "stops" and moving to the next section of hair in the same strand. In this case, the next strand will be cut in the same places as the previous one.
[0101] Zigzag texture (Fig. 6g). This texture is created as follows. A strand is cut at a chosen angle, with the scissors rotated 90° relative to their axis, first in one direction. A new strand is selected for cutting, approximately in the middle of the previously processed strand, and cut in the opposite direction. Subsequent strands are cut in the same manner. This creates an extremely chaotic texture, without any order. This cut is best suited for curly hair, as it emphasizes the existing volume and disordered texture.
[0102] In the fourth step, the working blade of the scissors is determined.
[0103] While it's possible to control the cutting process and results using geometric characteristics (choosing the cutting angle, the tool's axis of motion), physical ones can also be used. Specifically, choosing the working part of the shear blade.
[0104] In some non-limiting embodiments with reference to Fig. 7 of the present method, the working part of the scissor blade may be:
[0105] - using the middle section of the scissor blade, meaning 1-1.5 cm of the middle section is used as the cutting tool. Cutting hair this way results in a lengthening cut, where the upper layers of hair dominate the lower ones, as if pressing them down, creating shape and direction. By combining the geometric and physical characteristics of this technique, you can create any hair direction, curl, etc.
[0106] - using the outer part of the scissor blade (the tips). Only the tip of the tool is used during the cutting process. This method doesn't cut deep; rather, the work is done on the surface. This creates texture and refines the cut. However, this method is also suitable for creating a full-length haircut on short hair.
[0107] In the fifth step, the cut is made according to the parameters selected in the previous steps. The cut is made from top to bottom along the hair growth, holding the strand together with your fingers and moving downwards. A distinctive feature of the cut according to this invention is that the angle of the cut allows for the replacement of hair extensions and allows for working on large areas. The cut affects the balance of the hair, and the hairdresser uses the chosen texture to create direction.
[0108] For example, if a client has a strand of hair in their bangs that curls toward their eyes and gets in their way, the hairdresser will choose the appropriate cutting angle, for example, between 5° and 45°, to lengthen the hair and a diagonal texture in the direction opposite to the face. This will ensure that after the cut, the strand will not "get into" the client's face and will lie flat.
[0109] Implementation of the invention
[0110] Fig. 8 shows an example of a cut at an angle of approximately 45°, made on an artificial strand.
[0111] Fig. 9 shows an example of a hairstyle created using the present method. Fig. 9 depicts an elongated bob with medium-length hair. In the lower occipital area, 1-1.5 cm strands were used to create a soft, smooth, and even look. In the parietal, temporal, and lower occipital areas, 1.5-2 cm strands were used to create texture and volume. The mannequin clearly shows longer strands cut at a shallower angle of 20° in the bangs area, and shorter strands in other areas, at angles of 30°-40° in the remaining areas. The diagonal texture used in the bangs area is also clearly visible, allowing the hair to lie naturally in different directions relative to the mannequin's face. The mannequin clearly shows that the haircut is intended to be lengthening, with the top layers of hair dominating the bottom layers. To achieve this result, the middle part of the scissors blade was used as the working part.The haircut given as an example is characterized by the high quality of the cut, which affects the quality of the hair and allows the hairstyle to maintain its shape for a long time after the haircut.
