Description

[Technical Field]

[0001] The present disclosure relates to a haircutting method. [Background technology]

[0002] A conventional haircutting method that reduces hair volume while minimizing the difficulty of styling hair is disclosed in Patent Document 1. In the haircutting method of Patent Document 1, a plurality of spot areas are set side by side on a predetermined spot line on the scalp of a patient. The respective spot areas are arranged at intervals on the spot line.

[0003] In Patent Document 1, hair is cut in each spot area so that the length of the hair in these areas is 1 cm or less, and the length of the hair in the areas surrounding the spot area is 3 cm or more. In Patent Document 1, the space in the spot area creates a space in the hair growing around the spot line as an escape route for the hair growing from the periphery. As a result, the hair around the spot area is encouraged to flow toward the spot area. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-019270 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in Patent Document 1, the spot areas must be spaced apart on the spot line, and the spot lines must also be spaced apart. That is, the spot areas are formed discretely at intervals. Therefore, when viewed from the entire head, the range in which the hair volume can be adjusted by cutting is limited.

[0006] Furthermore, when cutting hair, it is often desired that the hair be kept tidy after the cut (in other words, a uniform look). However, Patent Document 1 does not particularly consider the technique of tidying the hair after the cut, so there is room for improvement.

[0007] The present disclosure has been made in light of the above-mentioned problems, and aims to provide a new haircutting method that can expand the adjustable range of hair volume and makes hair easier to manage. [Means for solving the problem]

[0008] In order to solve the above problem, a haircutting method according to one aspect of the present disclosure is a haircutting method for cutting hair of a recipient, comprising: a first removal step of removing a hair bundle that is a bundle of hair on the recipient's scalp as a first hair bundle from inside a first removal range that is formed in a rectangular shape with long sides of 1.5 cm and short sides of 1.0 cm; a first cutting step of dividing the hair included in the first hair bundle into a first standard number of hair strands that is a predetermined first standard number of hair strands or less, thereby forming a plurality of hair sections, and sequentially cutting each of the plurality of hair sections; a second removal step of removing the hair bundle as a second hair bundle from inside a second removal range that is formed in a rectangular shape with long sides of 1.5 cm and short sides of 1.0 cm in a portion adjacent to the first removal range; and a second cutting step of dividing the hair included in the second hair bundle into a second standard number of hair strands that is a predetermined second standard number of hair strands or less, thereby forming a plurality of hair sections, and sequentially cutting each of the plurality of hair sections.

[0009] According to the haircutting method of one aspect of the present disclosure, a hair strand on the recipient's scalp is removed as a first hair strand from inside a first removal range, and a next hair strand located inside a second removal range formed adjacent to the first removal range is removed as a second hair strand. This expands the adjustable range of hair volume compared to, for example, when spot areas are formed discretely at intervals as escape routes for the hair.

[0010] The first and second take-out ranges are formed in a rectangular shape with long sides of 1.5 cm and short sides of 1.0 cm. The hair included in the first hair bundle is cut sequentially into multiple hair sections divided by a preset first reference number of three or less. The hair included in the second hair bundle is cut sequentially into multiple hair sections divided by a preset second reference number of three or less. Therefore, the hair bundles to be taken out at one time are formed quantitatively and the number of hairs to be cut at one time is set quantitatively, thereby reducing variation in the condition of the hair after cutting. [Effects of the Invention]

[0011] According to the present disclosure, a novel haircutting method can be provided that can expand the adjustable range of hair volume and make hair easier to manage. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0013] The present disclosure will be described below with reference to the drawings. In the following description of the drawings, identical or similar parts are designated by identical or similar reference numerals. However, it should be noted that the drawings are schematic, and the relationship between thickness and planar dimensions, the thickness ratio of each device and each component, etc. may differ from the actual ones. Therefore, specific thicknesses and dimensions should be determined with reference to the following description.

[0014] Furthermore, it goes without saying that the dimensional relationships and ratios may differ between the drawings. Furthermore, the "left-right" and "up-down" directions in the following description are merely definitions for the convenience of explanation and do not limit the technical concept of the present disclosure. Therefore, for example, if the page is rotated 90 degrees, "left-right" and "up-down" are read interchangeably, and if the page is rotated 180 degrees, "left" becomes "right" and "right" becomes "left."

[0015] <How to cut hair> A haircutting method according to this embodiment will be described with reference to Figures 1 to 7. The haircutting method according to this embodiment is a method for cutting hair of a recipient. The recipient, such as a customer visiting a beauty salon, provides hair to be cut to a hairdresser.

[0016] The haircutting method according to this embodiment includes a washing step, a drying step, and a slice forming step. The haircutting method according to this embodiment further includes a first removal step, a first cutting step, a second removal step, and a second cutting step, as shown in FIG. 1 . While the subject performing the haircutting method in this embodiment is a hairdresser, the subject in this disclosure is not limited to a hairdresser and may be any subject. For example, the haircutting method according to this disclosure may be performed by a barber.

[0017] (Washing step) In the washing step, the hairdresser first washes the hair of the recipient who has come to the salon by shampooing or rinsing with water, etc. Washing increases the moisture content of each of the multiple hairs (hereinafter also simply referred to as "moisture").

[0018] (Drying step) Next, the hairdresser dries the recipient's hair using a towel or a dryer such as a hairdryer. In the present disclosure, the washing step and the drying step are optional. However, as will be explained later using examples, it is preferable that the average moisture content of the entire hair is less than 10% in order to more accurately grasp the hair's texture. Furthermore, the higher the average moisture content, the more likely the hairs are to stick together, which can lead to concerns about cutting more than the intended number of hairs. For this reason, it is preferable to keep the average moisture content low.

[0019] (Slice formation step) Next, the hairdresser sets slices on the recipient's hair. As shown in FIG. 2, in this embodiment, for example, horizontal slices are set so that they are stacked vertically. The slice width W is, for example, 1 mm or more and 1.5 cm or less. By setting the slice width in this manner, it is easy to adjust the amount of hair. Note that the slice formation step is not essential in the present disclosure.

[0020] (First removal step) Next, in step S2 in Fig. 1, the hairdresser extracts a first hair bundle from the scalp of the recipient. Specifically, as shown in Fig. 3, the first hair bundle is extracted from inside a first extraction range P1 set inside a slice of hair. Fig. 3 illustrates the first extraction range P1 set at the left end of the bottom slice.

[0021] As shown in FIG. 4, the first removal range P1 is formed in a rectangular shape with a long side of 1.5 cm and a short side of 1.0 cm. The shape formed by the roots of the multiple first hair bundles M1 inside the first removal range P1 is arbitrary as long as they are removed from inside the rectangular first removal range P1. In this embodiment, the shape of the roots of the first hair bundles M1 in FIG. 4 is triangular, but in the present disclosure, the shape of the first hair bundles may be any polygonal shape, such as a square or trapezoid, or may be circular, elliptical, or the like. The shape of the first hair bundles may also be linear.

[0022] 4 illustrates a state in which the long side of the first removal range P1 is arranged vertically and the short side is arranged horizontally, but in the present disclosure, the long side may be arranged horizontally and the short side may be arranged vertically. Also, in the present disclosure, the rectangle of the first removal range P1 in FIG. 4 illustrates a state in which the long side is arranged vertically and the short side is arranged horizontally, but in the present disclosure, it is not excluded that the rectangle of the first removal range may have its long side and short side arranged diagonally so that the long side intersects a vertical line and the short side intersects a horizontal line.

[0023] (First cutting step) Next, in step S2 in Fig. 1, the hairdresser divides the hair included in the first hair bundle into a first standard number of hair strands, which is set in advance, and forms a plurality of hair sections. A hair section is used as a unit to refer to a group of hair strands to be cut at one time. In step S3 in Fig. 1, the hairdresser cuts the hair sequentially for each of the plurality of hair sections.

[0024] As shown in Fig. 5, in this embodiment, the first reference number is three. The present disclosure is not limited to this, and the first reference number may be two or one. If the first reference number is four or more, the number of hairs to be cut becomes too large, making it difficult to manage the hair. Fig. 5 illustrates five hair sections H1 to H5, each divided into three hairs, among the hairs included in the first hair bundle M1, but the present disclosure is not limited to this, and the number of hair sections is arbitrary.

[0025] In this embodiment, the three hairs included in the hair portion H1 on the far left in Fig. 5 are cut at approximately the same position in the length direction (vertical direction in Fig. 5). In addition, in the five hair portions H1 to H5, the cutting positions are shifted toward the ends (lower side in Fig. 5) as one moves from left to right in Fig. 5. The right side of Fig. 5 illustrates an example of a hair portion HR that is left without being divided into the first standard number of hairs included in the first hair bundle. The number of hair portions HR to be left is set appropriately depending on the condition of the recipient's hair and the desired cutting style.

[0026] When cutting, by allowing the hair to hang naturally according to gravity, it becomes easier to identify the location of any curls or damage, and as a result, it becomes easier to accurately determine the cutting position. This improves the smoothness of the hair after cutting and makes it easier to manage the hair.

[0027] (Second removal step) Next, in step S4 of FIG. 1, after completing the first cutting step of the first hair bundle M1 in the first removal range P1, the hairdresser sets a second removal range P2 adjacent to the first removal range P1, as shown in FIG. 3. Like the first removal range P1, the second removal range P2 is formed in a rectangular shape with long sides of 1.5 cm and short sides of 1.0 cm. Then, as shown in FIG. 4, the hairdresser removes the hair bundle located inside the second removal range P2 from inside the second removal range P2 as the second hair bundle M2 following the first hair bundle M1. In this embodiment, the shape of the second hair bundle M2 in FIG. 4 is trapezoidal, but in the present disclosure, the shape of the second hair bundle may be any polygonal shape, such as a square or triangle, or may be a circle or an ellipse. The shape of the second hair bundle may also be linear.

[0028] In the present disclosure, even if the long and short sides of the rectangle of the first access range are arranged diagonally, the second access range can be set in a portion adjacent to the first access range. The first access range and the second access range may be adjacent, for example, so that the imaginary line connecting the centers of gravity of the adjacent rectangles is positioned on the same horizontal line, or so that the imaginary line extends parallel to the long or short side. Furthermore, "adjacent" includes both cases where the access ranges are in contact with each other and cases where they are arranged close to each other but slightly spaced apart.

[0029] Even if the first and second removal ranges are adjacent to each other, it is not necessary for the hair at the root of the first hair bundle to come into contact with the hair at the root of the second hair bundle. The state in which the hair at the root of the first hair bundle removed from the first removal range and the hair at the root of the second hair bundle removed from the second removal range are separated is included in the present disclosure. Other configurations in the second removal step are the same as those in the first removal step, so repeated explanations will be omitted.

[0030] (Second cutting step) Next, in step S5 of FIG. 1, the hairdresser divides the hair contained in the second hair bundle M2 into multiple hair sections by dividing them into a predetermined second reference number of three or less, as in the first cutting step. Then, in step S6 of FIG. 1, the hairdresser sequentially cuts the hair for each of the multiple hair sections. In this embodiment, the second reference number is three, but this is not limited to this in the present disclosure, and the second reference number may be two or one. If the second reference number is four or more, the number of hairs to be cut will be too large, making it difficult to manage the hair. The other configurations of the second cutting step are the same as those of the first cutting step, so repeated explanations will be omitted.

[0031] Then, after completing the second cutting step of cutting the second hair bundle M2 in the second take-out range P2, the hairdresser sets a third take-out range adjacent to the second take-out range P2 and performs the third take-out step of taking out the third hair bundle, just as when the second take-out step was started. The third take-out range is set in the same way as the first take-out range P1 and the second take-out range P2. The third hair bundle is taken out in the same way as the first hair bundle M1 and the second hair bundle M2. The third take-out range and the third hair bundle are not shown in the drawings.

[0032] Then, the hairdresser performs a third cutting step on the third hair bundle in the same manner as the second cutting step. Furthermore, the hairdresser sets a fourth removal range in a portion adjacent to the third removal range, and so on, and the removal and cutting steps are performed sequentially from left to right in the bottom slice in Figure 3.

[0033] After cutting all the areas to be removed in the bottom slice in Fig. 3, the hairdresser repeats the removing step and cutting step for the second slice from the bottom, for example, in the same way as for the bottom slice. Then, once cutting is completed for all the slices formed in the hair, the hair styling of the recipient is complete.

[0034] In the present disclosure, it is not essential that the haircutting method according to the present embodiment be performed on all removal areas included in one slice. The haircutting method according to the present embodiment may be performed on some of the removal areas included in one slice. Furthermore, in the present disclosure, it is not essential that the haircutting method according to the present embodiment be performed on all slices formed on the head. The haircutting method according to the present embodiment may be performed on some of the slices formed on the head. [Example]

[0035] The present inventors conducted the following Examples 1 and 2 as experiments to examine the average moisture value of the entire head of hair, which is suitable for the hair-cutting method according to this embodiment.

[0036] (Example 1: Low dryness) First, the present inventor measured the moisture content [%] of the recipient's hair at each site during the drying step after shampooing, when the hair was dried only with a towel. The recipient was an adult female. The measurements were performed using a commercially available electrical resistance moisture meter. The room temperature during the measurements was room temperature.

[0037] (Division of areas) Specifically, the present inventor first divided the recipient's entire head of hair into seven sections, as shown in Figures 6(A) and 6(B). The entire head of hair was divided into two sections, upper and lower, by a vertical ear-to-ear section V1, and the front side of the head, where the face is located, was divided into two sections, upper and lower, by a first horizontal line L1 that passes through the highest point of the bowl. The bowl is the part that protrudes most outward between the parietal region and the temporal region. Furthermore, each of the two upper and lower sections of the front side of the head was further divided into two sections, left and right, by the midline V2 of the human body. The ear-to-ear section V1 and the midline V2 intersect at the parietal region of the recipient's head.

[0038] The hair on the back side of the head, where the back of the head is located, is divided into three sections, upper and lower, by a first horizontal line L1 and a second horizontal line L2 that passes through the height of the top of the ears. Of the seven divided sections, there are four sections for the front hair and three sections for the back hair.

[0039] Next, the present inventors extracted one hair from each of the seven regions. Then, the present inventors measured the moisture content of the extracted hair at different positions on the root side and the tip side, with the center position in the length direction as the boundary. In other words, 14 measurements were obtained for the entire hair. In Figures 6(A) and 6(B), each of the 14 measurements is illustrated inside the hair divided into 14 sections. For the adult female illustrated in Figures 6(A) and 6(B), the average moisture content of the 14 measurements was approximately 14.3%.

[0040] Although not shown in the figures, the present inventors also measured the moisture [%] of the hair of other recipients in a state of drying only with a towel, for each part, in the same manner as in Figures 6(A) and 6(B). When drying only with a towel, the average moisture [%] of the hair of each of the 20 recipients was in the range of 10% or more and 30% or less. Then, the haircutting method according to the present embodiment was performed on the hair of the 20 recipients whose average moisture was in the range of 10% or more and 30% or less, and the cutting time for each was measured.

[0041] (Example 2: Highly dry conditions) Next, in the drying step, the present inventor measured the moisture [%] of the recipient's hair after washing and drying with a towel and a dryer under the same conditions as in Example 1. The measurement results in Figures 7(A) and 7(B) illustrate measurements of the hair of the same recipient as that of the adult woman illustrated in Figures 6(A) and 6(B), after drying with a towel and then drying with a dryer. In the case of the adult woman illustrated in Figures 7(A) and 7(B), the average moisture content of 14 measurements was approximately 1.81%.

[0042] Although not shown in the figures, the present inventors also measured the moisture [%] of the hair of other recipients at each site after drying with a towel and a dryer, in the same manner as in Figures 7(A) and 7(B). When dried with a towel and a dryer, the average moisture [%] of the hair of each of the 20 recipients was 3% or less. Then, the haircutting method according to the present embodiment was performed on the hair of the 20 recipients whose average moisture was 3% or less, and the cutting time for each was measured.

[0043] (Results of Examples 1 and 2) The average cutting time required for the haircutting method in Example 1 was about 1.5 times the average cutting time required for the haircutting method in Example 2. This is thought to be because in Example 1, where the average moisture content is in the range of 10% or more and 30% or less, it takes more time to identify the location of hair curls and damage when cutting the hair compared to Example 2, where the average moisture content is 3% or less.

[0044] (Additional Example: Medium Dry Condition) The present inventors also carried out an additional example of the haircutting method according to the present embodiment on hair with an average moisture content of more than 3% and less than 10%. The average cutting time required for the haircutting method in the additional example was shorter than the average cutting time for Example 1 and longer than the average cutting time for Example 2. The average cutting time required for the haircutting method in the additional example was approximately 1.2 times the average cutting time required for the haircutting method in Example 2.

[0045] (Consideration) The relationship between the average cutting time required in a haircutting method and the average moisture content of the hair can be considered as follows: If the hair to be cut has curls or scratches during haircutting, it is necessary to determine the appropriate position for inserting the scissors according to the location of the curls or scratches so that the curls or scratches do not remain on the hair after cutting. In this regard, in ideal hair without curls or scratches, the hair grows in a straight line from the roots to the tips. However, if curls or scratches are formed, the hair will bend at the location of the curls or scratches, protruding outward from its original straight line.

[0046] Here, the more moisture there is in the hair, the smaller the bend at the location of the curl or flaw, making it difficult to distinguish the appearance of the curl or flaw. Conversely, the less moisture there is in the hair, the larger the bend at the location of the curl or flaw, making it easier to distinguish the appearance of the curl or flaw.

[0047] From the above Examples 1 and 2 and the additional examples, it was found that the average moisture content is preferably less than 10% in order to obtain the effect of shortening the cutting time, and it was further found that the average moisture content is more preferably 3% or less in order to enhance the effect of shortening the cutting time.

[0048] (Action and effect) According to the haircutting method of this embodiment, a hair strand on the recipient's scalp is extracted as a first hair strand M1 from inside a first extraction range P1, and the next hair strand located inside a second extraction range P2 formed adjacent to the first extraction range P1 is extracted as a second hair strand M2. This expands the adjustable range of hair volume compared to, for example, when areas for hair escape are formed discretely at intervals.

[0049] Here, when hair is cut using thinning shears (i.e., combing shears) as in the past, the ends of the hair may be easily bent after cutting. This makes the hair difficult to manage and prone to curling as the hair grows. Furthermore, when hair is cut using a razor as in the past, the cuticle of the hair is easily damaged. This makes the hair difficult to manage, just like with thinning shears, and prone to split ends and curling as the hair grows.

[0050] Furthermore, even if ordinary hair-cutting scissors are used to adjust the length of hair as in the past, if the hair is simply cut vaguely without following a specific procedure, the hair tends to become dry after cutting. Also, even if the hair looks neat and tidy immediately after cutting, it becomes difficult to maintain its tidy shape as the hair grows.

[0051] In this regard, in this embodiment, the first take-out range P1 and the second take-out range P2 are formed in a rectangular shape with a long side of 1.5 cm and a short side of 1.0 cm. Furthermore, the hair included in the first hair bundle is cut sequentially into multiple hair sections divided by a preset first reference number of three or less. The hair included in the second hair bundle is cut sequentially into multiple hair sections divided by a preset second reference number of three or less. Therefore, the first hair bundle and the second hair bundle to be taken out at one time are formed quantitatively, and the number of hairs to be cut at one time is set quantitatively. In other words, a specifically set procedure is executed.

[0052] Therefore, in this embodiment, it is possible to reduce variations in the condition of hair after cutting. Furthermore, it is possible to achieve a smoother finish to hair after cutting and reduce the occurrence of split ends. Furthermore, since hair is easier to manage after cutting, it is easier to give it a glossy finish. Furthermore, since hair is less likely to stick out and stick out, it is easier to maintain its manageability even when the hair grows out. Furthermore, since hair is easier to manage after cutting, it is easier to give it the desired hair flow and is less likely to be damaged.
