[Figure 6] FIG. 2 is a schematic diagram for explaining the hair cutting method according to the first embodiment, as observed from the front. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, examples of the embodiments of the present invention will be described with reference to the drawings. Note that components common to the following embodiments (and modified examples and examples) may be given the same reference numerals as those mentioned above, and descriptions thereof may be omitted. In addition, when referring to the shape, positional relationship, etc. of components, etc., it is intended to include those that are substantially similar or similar to the shape, etc., unless otherwise specified or considered to be clearly different in principle.

[0014] The haircutting method according to the present invention is particularly suitable for cutting hairstyles for men.

[0015] The haircutting method according to the present invention includes the steps of dividing hair and cutting the hair.

[0016] <Embodiment 1> Fig. 1 is a schematic diagram for explaining an example of a haircut method according to embodiment 1, in which (a) the head is observed from the side and (b) the head is observed from the back. Note that Fig. 1(a) is observed from the left, but when observed from the right, it appears symmetrical (the same applies to Figs. 2(a), 3(a), 4(a) and 5 below).

[0017] <Step to divide the hair> The step of dividing the hair includes dividing the hair into a plurality of sections, a left and right side section 1 and a left and right back section 2, by a vertical line V above the ears and a center line C that divides the head equally into left and right, and dividing the hair into upper and lower blocks by a weight line that adds weight. That is, the vertical line V is the boundary that divides the hair into front and back sections, and the weight line is the boundary that divides the hair into upper and lower blocks.

[0018] <Setting weight points and dividing into blocks> The weight lines include a horizontal line H of a predetermined height whose rear end intersects with a vertical line V, and a back weight line W. The left and right side sections 1 are divided (segmented) into upper and lower blocks by the left and right horizontal lines H, which are the first weight lines, and the left and right back sections 2 are divided into upper and lower blocks by the left and right back weight lines W, which are the second weight lines.

[0019] In order to determine the weight line, three weight points are set here: a first weight point P1, a second weight point P2, and a third weight point P3. A total of five weight points are set when the left and right heads are combined.

[0020] The third weight point P3, which is the connection point from the horizontal line H to the back weight line W, is set at the intersection of the vertical line V and the horizontal line H. For example, for a normal hairstyle, the vertical line V (also called "ear-to-ear" connecting both ears) is set above the ears, the horizontal line H is set at a height according to the hairstyle, and the third weight point P3 is set at the point where the rear end of the horizontal line H intersects with the vertical line V. Note that the vertical line or horizontal line here refers to a line that is approximately vertical or approximately horizontal to the floor when the person to be treated, such as a customer, is sitting in a normal posture.

[0021] The third weight point P3, the vertical line V, and the horizontal line H may be set with consideration of both the vertical line V and the horizontal line H, and the line that passes through the third weight point P3 approximately vertically may be determined as the vertical line V, and the line that extends approximately horizontally forward may be determined as the horizontal line H.

[0022] The first weight point P1 is set at a height on the center line C according to the hairstyle, and is usually set at a position lower than the third weight point P3.

[0023] The second weight point P2 is set between the first weight point P1 and the third weight point P3. The back weight line W is configured by connecting the first weight point P1, the second weight point P2, and the third weight point P3 in the order P1-P2-P3, and is configured in a V-shape or U-shape with the second weight point P2 at the bottom.

[0024] More specifically, the second weight point P2 is set at a position shifted downward from a point in the middle (e.g., a middle part corresponding to approximately 1 / 5 of the total length) of a virtual line (dashed line in the drawing) that connects the first weight point P1 and the third weight point P3 at the shortest distance along the shape of the head. More preferably, the second weight point P2 is set at a position shifted downward from the middle point of the virtual line (dashed line in the drawing) that connects the first weight point P1 and the third weight point P3 at the shortest distance along the shape of the head. The distance shifted downward is determined depending on the hairstyle.

[0025] In the haircutting method of this embodiment, as described above, the back weight line W that divides the back section 2 into blocks is always configured by setting the second weight point P2 and connecting P1-P2-P3 in that order based on this. In this way, instead of connecting at two points, the first weight point P1 and the third weight point P3, the haircutting method of this embodiment connects at three points by setting the second weight point P2 shifted downward between them, thereby preventing mistakes such as cutting too much and gouging out the weight part when cutting the hair.

[0026] According to the method of this embodiment, even an inexperienced hairdresser or barber (hereinafter referred to as "hairdresser") can reliably prevent overcutting of the weight portion. Also, even an experienced hairdresser can easily maintain quality even in a short time of cutting by implementing the method of this embodiment. In this embodiment, the hair can be divided into a total of eight areas by dividing into sections and blocks as described above.

[0027] <Steps for cutting hair> In the step of cutting the hair, the hair of the upper block and the hair of the lower block are cut separately based on the above-mentioned division into sections and blocks. Preferably, the hair cutter uses a hair clip such as a pin, clip, or duckbill to hold the hair in place so that the weight line can be seen, and then cuts the hair. By making the weight line clear, the cut can be made with less mistakes and with better quality.

[0028] The cutting is not particularly limited, but preferably, the hair in the lower blocks (here, lower blocks B1 and B2) is cut from bottom to top up to the weight run. More preferably, the hair in lower block B1 is cut before the hair in lower block B2. Cutting in this order is less likely to fail. Next, the hair in the upper blocks (upper blocks B3 and B4) is cut from bottom to top to match the weight line.

[0029] The setting of the weight line and the cutting may be performed in parallel, or the setting of the weight line may precede the cutting. As an example, a horizontal line H and a back weight line W are set to divide the hair into upper and lower blocks, and then the hair is cut. As an example, a horizontal line H is set to divide the hair in the side section 1 into upper and lower blocks, and then the lower block B1 is cut, and then the back weight line W is set and the lower block B2 is cut. As an example, a back weight line W is set to divide the hair in the back section 2 into upper and lower blocks, and then the lower block B2 is cut, and then the horizontal line H is set and the lower block B1 is cut.

[0030] The haircutting method of this embodiment may use any conventional technique as appropriate, as long as it does not deviate from the spirit of the present invention. For example, cutting of the bangs or layer cutting is performed as appropriate. For cutting, clippers may be used, scissors may be used, or both may be used. The specific cutting method is not particularly limited.

[0031] <Modification 1 of the First Embodiment> FIG. 2 is a schematic diagram for explaining an example of a haircut method relating to variant example 1 of embodiment 1, and is a schematic diagram for explaining the head observed from (a) the side and (b) from the back (parting of the right head is not shown).

[0032] The haircutting method of this example differs from the above-mentioned embodiment 1 in that the step of dividing the hair further includes dividing the hair into parts based on weight points. In this parting, one or both of the lower block B2 and the upper block B3 of the divided back section 2 are divided (segmented) into two or more parts by one or both of a part line N intersecting with the third weight point P3 and a part line M intersecting with the second weight point P2.

[0033] As an example, the lower block B2 is divided into a lower part B22 and a lower part B23 from the rear side to the front side, in that order, with a part line M that intersects (passes through) the second weight point P2 as a boundary, as shown in the figure.

[0034] As an example, the upper block B3 is divided into upper parts B31, B32, and B33 from the rear to the front, with the part line N intersecting the part line M and the third weight point P3 as the boundaries, as shown in the figure.

[0035] In this way, the haircutting method of this example further divides the hair into parts based on the weight points, making it easier to align the hair with the back weight line W when cutting, and making subsequent cuts easier. In this example, the hair can be divided into a total of 14 areas by dividing the hair into sections, blocks, and parts.

[0036] <Embodiment 2> 3 is a schematic diagram for explaining an example of a haircut method according to embodiment 2, in which (a) the head is observed from the side and (b) the head is observed from the rear. Hereinafter, the description of the points in common with embodiment 1 (form 1) will be omitted as appropriate, and the description will focus on the points that are different.

[0037] <Step to divide the hair> The step of dividing the hair in this embodiment, like the embodiment described above, includes dividing the hair into multiple sections, left and right side section 1 and left and right back section 2, by a vertical line V above the ears and a center line C that divides the head equally into left and right sections, and dividing the hair into upper and lower blocks by a weight line, which is a line that adds weight.

[0038] In this embodiment, the first weight point P1, the second weight point P2, the third weight point P3, the vertical line V, the horizontal line H, and the back weight line W are set in the same manner as in the above embodiment. The division into front and rear sections by the vertical line V, and the division into upper and lower blocks by the weight lines are also the same as in the above embodiment.

[0039] In this embodiment, the back weight line W is configured in the same manner as in the above embodiment, and therefore the same effects as in the above embodiment can be obtained.

[0040] This embodiment further differs from the above embodiment in that it includes secondary block division.

[0041] That is, in this embodiment, the block division of the above embodiment is the primary block division, and based on this, secondary block division is further performed. In the secondary block division, center width lines CB are set on both the left and right sides of the center line C, and the hair in the upper blocks B4 and B3 of the left and right side sections 1 and the left and right back sections 2 between the left and right center width lines CB is divided into a front center block B5 that covers the frontal area, and an upper center block B6 that is the remainder. That is, in the secondary block division, center blocks (front center block B5 and upper center block B6) that do not belong to either the upper block B4 or the upper block B3 are separately defined.

[0042] In this way, by setting center width lines CB on both sides of center line C for the left and right side sections 1 and the left and right back sections 2, and defining the portion between the center width lines CB and above the weight line as the center block, it is possible to smoothly connect the basic cut and layered cut described below, making it easier to maintain the quality of the hair cut.

[0043] In this embodiment, the hair on the left and right head is divided into blocks B1 to B4 by the primary block division in the above embodiment, whereas the hair on the left and right head is further divided into blocks B1 to B6 by the secondary block division. Note that in this embodiment, the hair can be divided into a total of 10 areas by the above section division and block division.

[0044] <Steps for cutting hair> In the step of cutting the hair, the hair of the upper block and the hair of the lower block are cut separately based on the above-mentioned division into sections and blocks. In this embodiment, as in the above-mentioned embodiment, the hair cutter preferably uses a hair clip such as a pin, clip, or duckbill clip to hold the hair in place so that the weight line can be seen before cutting. By making the weight line clear, the cut can be made with less chance of failure and with better quality.

[0045] Although the cutting is not particularly limited, it is preferable to cut the hair in the lower blocks (lower blocks B1 and B2) from below to above up to the wait run first. More preferably, the hair in lower block B1 is cut before the hair in lower block B2. Cutting in this order is less likely to fail.

[0046] Next, the hair in the upper blocks (upper block B3 and upper block B4) is cut from the bottom up to fit the weight line.

[0047] As in the above embodiment, the setting of the weight line may precede the cutting, or the cutting may be performed in parallel.

[0048] Finally, the front hair of the front center block B5 is cut and layered. That is, the step of cutting hair in this embodiment includes a basic cut to shorten the length and a layer cut to add layers. The hair of the upper center block B6 is cut by a basic cut to shorten the length and also by layering, and is used as a guide panel for layer cutting. Here, a panel refers to a bundle of hair that is separated into an amount that can be cut at one time when cutting hair, and a guide panel refers to a panel that serves as a reference for other panels when performing layer cutting.

[0049] In this embodiment, by separately defining the front center block B5 and the upper center block B6 in this way, a smooth transition from the basic cut to the layer cut can be achieved, and the quality of the cut can be more easily maintained.

[0050] <Modification 1 of the second embodiment> FIG. 4 is a schematic diagram for explaining an example of a haircut method relating to variant example 1 of embodiment 2, in which (a) the head is observed from the side and (b) the head is observed from the back (parting of the right head is not shown).

[0051] The step of dividing the hair in this example differs from that in the above-mentioned embodiment 2 in that it further includes parting by a center width line CB. In this parting, the hair in the lower blocks B2 of the left and right back sections 2 between the left and right center width lines CB is divided into a center part B21 shared by the left and right lower blocks B2.

[0052] By defining the common center part B21 in this manner, it becomes easier to connect the two lower blocks B2 and to cut them.

[0053] The step of dividing the hair in this example differs from that in the above-described embodiment 2 in that it further includes dividing the hair into parts based on weight points. In this dividing, one or both of the upper block B3 and the lower block B2 of the back section 2 are divided into two or more parts by one or both of a part line N intersecting with the third weight point P3 and a part line M intersecting with the second weight point P2.

[0054] In this parting, as shown in the figure, the portion of the lower block B2 other than the center part B21 is divided from the rear side to the front side, in order, into a lower part B22 and a lower part B23, with a part line M passing through the second weight point P2 as a boundary. Also, the upper block B3 is divided from the rear side to the front side, in order, into an upper part B31, an upper part B32, and an upper part B33, with a part line N intersecting the part line M and the third weight point P3 as a boundary.

[0055] In this way, by dividing the hair into parts based on the weight points, it becomes easier to align the hair with the back weight line W when cutting, making subsequent cuts easier. In this example, the hair can be divided into a total of 17 areas by dividing the hair into sections, blocks, and parts.

[0056] <Example> Fig. 5 is a schematic diagram for explaining the hair-cutting method according to Example 1, as observed from the side. Fig. 6 is a schematic diagram for explaining the hair-cutting method according to Example 1, as observed from the front.

[0057] The hairdresser or the like who is providing the service first listens to the customer's desired hairstyle by talking to the customer or by having the customer choose from a hairstyle menu. In this example, the customer is assumed to be male.

[0058] Based on the hairstyle description, the hairdresser will perform the procedure below while imagining the final hairstyle that the customer will have.

[0059] <1. Setting and cutting the weight line> (1) Determine the third weight point P3. Here, the vertical line V is determined to be above the ear, and the height of the horizontal line H is determined according to the hairstyle, to determine the third weight point P3.

[0060] (2) Determine the first weight point P1. The first weight point P1 is determined at a height position on the center line C according to the hairstyle. The first weight point P1 is located lower than the third weight point P3.

[0061] (3) The second weight point P2 is determined. Here, it is determined to be a position shifted downward from the midpoint of the line that connects the first weight point P1 and the third weight point P3 in the shortest distance along the shape of the head. The distance to shift is determined according to the hairstyle. The second weight point P2 is the bottom of the V or U shape formed by P1-P2-P3. The line P1-P2-P3 is determined as the back weight line W.

[0062] Use clips or duckbill clips to secure the hair in the upper block so that the weight lines (horizontal line H, back weight line W) are visible.

[0063] When cutting men's hair, it is easy to make the mistake of cutting the weight part too short and gouging it out. By determining the back weight line W in this way and making it clearly visible, such mistakes can be prevented with certainty.

[0064] (4) Cut the hair in the lower block B1. In this example, the hair is divided into blocks and parts in the same manner as in the modified example of the second embodiment, resulting in a total of 17 areas. Here, the hair in the lower block B1, which is divided by the vertical line V and the horizontal line H, is cut from below to above up to the horizontal line H.

[0065] (5) Cut the hair in the lower block B2. Here, the hair in the lower block B2, which is divided by the vertical line V and the back weight line W, is cut from bottom to top up to the back weight line W. The hair is cut into parts, starting from the center, in the order of center part B21, lower part B22, and lower part B23. For the lower part B23, cut while also paying attention to the lower block B1 and lower part B22.

[0066] (6) Cut the hair in the upper block B3. Here, the hair in the upper block B3, which is divided by the vertical line V, the center width line CB, and the back weight line W, is cut from below to match the back weight line W. The hair is cut in parts, starting from the center, in the order of upper part B31, upper part 32, and upper part 33.

[0067] (7) Cut the hair in the upper block B4. Here, the hair in the upper block B4, which is divided by the vertical line V, the center width line CB, and the horizontal line H, is cut from below to match the back weight line W. The cut is done while keeping in mind the part B33 as well.

[0068] As described above, in this embodiment, the wait line is set first, and the block B1 is cut first. This order is less likely to cause errors.

[0069] The above cuts are done by setting a weight line and shortening the length of the hair while adjusting the overall silhouette accordingly. This cut can be done with clippers, scissors, or both. The specific cutting method is not limited.

[0070] <2. Cutting bangs> Cut the hair in the front center block B5. This part of the hair is called the bangs, and we will cut it to the length you want, based on your request.

[0071] Once the hair has been cut using the above steps, the basic outline will be complete. As the above is an adjustment to the silhouette and length, there are no intentional layers, and (if the hair is long) the silhouette will resemble a bob cut. Depending on the length, some layers may remain from a previous visit. In this application, a cut to shorten the length like this is called a basic cut, and a cut to intentionally add layers is called a layered cut.

[0072] <3. Center block layer cut> The hair in the upper center block B6 is cut. First, the hair around the whorl is cut to the desired length based on the customer's request. Then, as shown in Figure 5, this area is cut using guide panel a as a guide, cutting backwards in a straight line from guide panel a, panel b, and panel c, and cutting forwards in a straight line from guide panel a, panel f, and panel d.

[0073] In other words, instead of connecting the panels in a circular fashion as shown by the dashed lines in Figure 5, toward the rear, the guide panel a, the panel b at the position corresponding to the upper part B32, and the panel c immediately above the first weight point P1 are cut in a straight line by taking a shortcut. Also, toward the front, panel f is determined as the midpoint between the guide panel a and the panel d of the front center block B5, and is cut in a straight line by taking a shortcut. By cutting in a straight line in this way, bulging can be suppressed.

[0074] <4. Layer cut other than center block> Following the center block panels, perform layer cutting for the upper block B3 and upper block B4. Here, cut panel b between guide panel a and panel c so that it connects along the head circumference.

[0075] As shown in Figure 6, when observed from the front, the panel connecting guide panel a and panel e just above horizontal line H can be designed so that panel b fits directly between guide panel a and panel e, following the curve of the head, thereby preventing unnecessary bulging.

[0076] 5 and 6 are schematic diagrams showing where the panels are taken out and how they are connected and cut, and do not specify the panel slicing direction (the direction in which the panels are separated) or the panel pull-out direction. It goes without saying that the slicing direction and panel pull-out direction may be changed as appropriate to perform layer cutting or gradation cutting.

[0077] The quality of a haircut depends largely on the experience and skill of the hairdresser, but with this embodiment, even an inexperienced hairdresser can provide a stable, high-quality haircut without mistakes. This embodiment is particularly suitable for short haircuts (e.g., about 30 minutes) for normal hairstyles.

[0078] It goes without saying that the above embodiment and its modifications and examples are not limited to cutting men's hair (particularly short hair), but may also be applied to cutting women's short hair, for example. In other words, the above embodiment and its modifications and examples can be applied to anyone, regardless of gender.

[0079] The above describes the embodiment, examples, and modifications of the haircut method according to the present invention, but these are merely examples of the present invention, and the present invention is not limited to these. The present invention includes combinations of the above embodiments and their modifications, as well as various other modifications. Various additions, modifications, and partial deletions are possible within the scope of the conceptual idea and intent of the present invention derived from the contents defined in the claims and their equivalents.
