Description

[Technical Field]

[0001] The present invention relates to a hair dyeing method and a hair coloring agent identification system. [Background technology]

[0002] Hair has traditionally been dyed using hair coloring agents at beauty salons and hair coloring specialty stores. By using different hair coloring agents, customers can achieve different colors depending on their needs. However, the choice of which hair coloring agent to use and how to use it is left up to the staff at the beauty salon or hair coloring specialty store, and the desired color may not always be achieved. Furthermore, the appropriate amount of hair coloring agent to use varies depending on the length of the hair, and if the appropriate amount is not used, there is a problem of wasting the hair coloring agent.

[0003] However, due to the influence of the temperature of the head, the part of the hair close to the scalp is more easily dyed than the part away from the scalp. Therefore, a hair coloring agent is usually applied to the part away from the scalp, and then, after a certain time, the hair coloring agent is applied to the part close to the scalp. Therefore, after applying the hair coloring agent to the part away from the scalp, a waiting time occurs before applying the hair coloring agent to the part close to the scalp, which causes a problem that it takes a long time to complete the coloring. Summary of the Invention [Problem to be solved by the invention]

[0012] Hereinafter, embodiments of the present invention will be described, but the present invention is not limited to the following embodiments as long as they do not contradict the spirit of the present invention.

[0013] FIG. 1 is a block diagram showing the configuration of a hair coloring agent identification system according to an embodiment of the present invention. As shown in the figure, the hair coloring agent identification system is composed of a store terminal 1, a server device 2, and a communication network 3. For example, the store terminal 1 is installed in a store that provides hair coloring services to customers, such as a beauty salon or a hair coloring specialty store, and is operated by a store clerk. The store terminal 1 can communicate with the server device 2 via the communication network 3. The hair coloring agent identification system may also include multiple store terminals 1. In this embodiment, the hair coloring agent identification system is configured to include the store terminal 1 operated by a store clerk and the server device 2, but is not limited to this. For example, the store terminal 1 may be replaced with a computer device operated by a person other than a store clerk.

[0014] The store terminal 1 is not particularly limited as long as it is a computer device having a display screen and an input unit. The store terminal 1 may be a stationary type installed in a store, or a portable type that can be carried by a store clerk when moving around. Examples of the store terminal 1 include conventional mobile phones, tablet terminals, smartphones, and desktop or notebook personal computers.

[0015] 2 is a block diagram showing the configuration of a store terminal according to an embodiment of the present invention. The store terminal 1 includes a control unit 11, a main memory 12, a storage unit 13, an input device 14, a display device 15, and a communication interface 16, all of which are connected by a bus.

[0016] The control unit 11 is composed of a CPU and a ROM. The control unit 11 executes programs stored in the storage unit 13 and controls the store terminal 1. For example, a RAM is used as the main memory 12. The main memory 12 is a work area for the control unit 11. The storage unit 13 is a memory area for saving programs and data. The control unit 11 performs arithmetic processing based on the programs and data read from the main memory 12 and data input via the input device 14.

[0017] The display device 15 has a display screen. The control unit 11 outputs a video signal for displaying an image on the display screen according to the result of the arithmetic processing. Here, the display screen may be a touch panel equipped with a touch sensor. In this case, the touch panel functions as the input device 14.

[0018] The communication interface 16 can be connected to the communication network 3 wirelessly or via a wire, and can transmit and receive data to and from the server device 2 or the POS register 5 via the communication network 3. Data received via the communication interface 16 is loaded into the main memory 12, and the control unit 11 performs arithmetic processing.

[0019] 3 is a block diagram showing the configuration of a server device according to an embodiment of the present invention. The server device 2 includes a control unit 21, a main memory 22, a storage unit 23, and a communication interface 24, all of which are connected by a bus.

[0020] The control unit 21 is composed of a CPU and a ROM, and executes programs stored in the storage unit 23 to control the server device 2. The control unit 21 also has an internal timer that measures time. The main memory 22 is a work area for the control unit 21. The storage unit 23 is a storage area for saving programs and data. The control unit 21 reads out programs and data from the main memory 22 and performs program execution processing based on information received from the store terminal 1 or the POS register 5, etc.

[0021] Next, the hair coloring agent identification process in the hair coloring agent identification system will be described. Figure 4 is a diagram showing a flowchart of the hair coloring agent identification process in the hair coloring agent identification system according to an embodiment of the present invention. First, a store clerk starts an application program downloaded to the store terminal 1 and accesses the server device 2 to log in to the hair coloring agent identification system (step S1).

[0022] The store clerk operates the store terminal 1 to input the hair type corresponding to the customer's hair to be dyed (step S2). The store terminal 1 displays multiple hair types as options, and the customer can select one of them by operating the store terminal 1. FIG. 5 is a diagram showing an example of a figure imitating hair according to an embodiment of the present invention. Figure 50 is a figure imitating hair, and is preferably represented as a triangle. The figure can be recognized by regarding the side with the base of the triangle as the hair root side and the side with the vertex of the triangle opposite the base as the hair tip side, and the hair root side and hair tip side can be distinguished at a glance. Here, the base of the triangle is the shortest side of the three sides that form an isosceles triangle such as figure 50.

[0023] Furthermore, it is preferable that the graphic 50 is divided into a plurality of regions 51 by lines parallel to the base of the triangle. The graphic 50 has at least one region 51 (regions 51a, 51b, 51c, etc.) and symbols 52 (symbols 52a, 52b, 52c, etc.). A symbol 52 is written in association with each region 51. For example, a predetermined symbol is placed in a predetermined region, such as symbol 52a written in region 51a. In FIG. 5, the symbols with numbers 1 to 4 written inside circles are referred to herein as "Symbol 1," "Symbol 2," "Symbol 3," and "Symbol 4," respectively.

[0024] The figure 50 is divided into multiple regions 51 according to the location of the hair (whether it is the root portion of the hair near the scalp, the center portion, the tip, etc.) and its characteristics. Here, the figure 50 is divided into multiple regions 51 according to the location of the hair and whether it is dyed (previously dyed hair) or undyed (newly grown hair). In FIG. 5(a), the region 51a corresponding to "symbol 1" (i.e., the root portion of the hair) is shown with diagonal lines, and is undyed. Also in FIG. 5(a), the region 51b corresponding to "symbol 2" (i.e., the center portion of the hair) and the region 51c corresponding to "symbol 3" (i.e., the tip of the hair) are shown in white, and are dyed. On the other hand, in FIG. 5(b), the region 51a corresponding to "symbol 1" and the region 51b corresponding to "symbol 2" are shown with diagonal lines, and are undyed. Also in FIG. 5(b), the region 51c corresponding to "symbol 3" is shown in white, and is dyed. Furthermore, in FIG. 5(c), the region 51a corresponding to "Symbol 1," the region 51b corresponding to "Symbol 2," and the region 51c corresponding to "Symbol 3" are shown with diagonal lines and are undyed. In step S2, by operating the store terminal 1, the hair type corresponding to the customer's hair can be input from the different hair types shown in FIGS. 5(a) to 5(c). Note that in FIG. 5, the figure 50 is configured with three regions, but the figure 50 may be configured with one region, two regions, or four regions. Also, the figure 50 may have regions other than those shown in FIG. 5, all of which are new hair.

[0025] The store clerk, referring to a color sample or the like, asks the customer what color they want their hair dyed to be. The store clerk asks the customer what color and brightness they want after dyeing, and inputs the color and brightness information from the customer into the input unit of the store terminal 1 (step S3). Here, colors are not particularly limited, but examples include brown, orange, yellow, purple, violet, and red. Brightness also has multiple levels. For example, if brightness is classified into 10 levels, and if red is represented as "R," the brightest brightness can be represented as "R1" and the darkest brightness as "R10." The larger the number, such as "R1," "R2," and "R3," the darker the color.

[0026] Next, the store clerk operates the store terminal 1 to input the hair length of the portion corresponding to each region of the graphic 50 (step S4). For example, if the graphic of FIG. 5(a) is selected in step S2, the store clerk inputs the hair length of the portion corresponding to each of the regions 51a to 51c. The same hair length can be input for each region 51, or different hair lengths can be input. The hair length does not need to be input exactly; it can be selected from multiple options, such as "0-2 cm," "2-5 cm," "5-10 cm," "10-15 cm," "15-20 cm," "20-25 cm," and "25-30 cm." The hair length near the scalp (the hair length corresponding to region 51a in FIG. 5) may be fixed at the shortest length, "0-2 cm." By inputting the hair length of the portion corresponding to each region of the graphic in this way, the length of newly grown hair and the length of previously dyed hair can be identified.

[0027] Next, the store clerk operates the store terminal 1 to input the undercolor (step S5). Here, the undercolor refers to the color and / or brightness of previously dyed hair. Previously dyed hair is hair that has a different color or brightness from the customer's original hair due to previous dyeing. Inputting the undercolor in step S5 is necessary if a pattern of previously dyed areas is input in step S2. In step S5, the store clerk observes the previously dyed portions of the customer's hair and operates the store terminal 1 to input the color and brightness of the previously dyed portions. Here, colors are not particularly limited, but examples include brown, orange, yellow, purple, violet, and red. Brightness also has multiple levels. For example, if brightness is classified into 10 levels, and if red is represented as "R," the brightest brightness can be represented as "R1" and the darkest brightness as "R10." As the numbers increase, such as "R1," "R2," and "R3," the color becomes darker. If the customer's hair to be dyed is only new hair, step S5 can be omitted.

[0028] The store clerk can also input the customer's hair type, the desired color and brightness after dyeing, the length of each region of the hair, and the dyeability of the person's hair. Depending on hair type, some hair is more easily dyed than others, and based on this information, the hair coloring agent to be used can be changed. The hair dyeability can be input in three levels, for example, "easy to dye," "normal," and "difficult to dye." Note that while the input is made to the input unit of the store terminal 1 here, for example, the server device 2 can store the hair dyeability of each customer along with their past usage history, and the hair coloring agent to be used can be changed based on the information on the hair dyeability stored in the server device 2.

[0029] When the necessary information is input at the store terminal 1 in steps S2 to S5, this information is sent to the server device 2, which then specifies the type and amount of hair coloring agent to be used (step S6). In step S6, different types and amounts of hair coloring agent to be used are specified for each of the areas of the hair near the scalp, the center, and the ends, depending on the hair type input in step S2.

[0030] FIG. 6 is a diagram showing an example of a hair coloring agent table according to an embodiment of the present invention. A hair coloring agent table 30 is stored in the storage unit 13 of the server device 2. The hair coloring agent table 30 in FIG. 6(a) stores a hair coloring agent 32 for dyeing the undyed portion of the hair near the scalp (newly grown hair) and a hair coloring agent 33 for dyeing the undyed portion of the hair other than the portion near the scalp (newly grown hair), in association with a color and brightness 31 after dyeing. Each of the hair coloring agents 32 and 33 may store only one type of hair coloring agent, or may store the types, brands, product numbers, etc. of multiple hair coloring agents and their blending ratios.

[0031] In step S6, by referring to the hair coloring agent table 30, the type and composition of hair coloring agents for dyeing new hair near the scalp, and the type and composition ratio of hair coloring agents for dyeing new hair other than near the scalp, which correspond to the color and brightness desired by the customer, can be identified.

[0032] Because the body temperature of the person to be dyed makes the portion of the hair near the head (for example, the portion within about 2 to 3 cm from the root of the hair) easier to dye, the type and blending ratio of hair coloring agent 32 for dyeing new hair near the scalp is the same color as, but different in brightness from, hair coloring agent 33 for dyeing new hair other than that near the scalp, and is registered in hair coloring agent table 30. It is preferable that the type and blending ratio of hair coloring agent 32 be registered such that, when applied to the same portion of hair, it will dye the hair a darker color with the same color than hair coloring agent 33.

[0033] For example, if "R5" is entered as the color and brightness after dyeing in step S3, 70% by mass of hair coloring agent A and 30% by mass of hair curly agent B are specified as hair coloring agents for dyeing newly grown hair near the scalp, and 65% by mass of hair coloring agent A and 35% by mass of hair curly agent B are specified as hair coloring agents for dyeing newly grown hair other than near the scalp. On the other hand, if "R6" is entered as the color and brightness, 75% by mass of hair coloring agent A and 25% by mass of hair curly agent B are specified as hair coloring agents for dyeing newly grown hair near the scalp, and 70% by mass of hair coloring agent A and 30% by mass of hair curly agent B are specified as hair coloring agents for dyeing newly grown hair other than near the scalp.

[0034] The hair coloring agent identified in step S6 may be changed depending on the input dyeability. For example, if the dyeability is "normal" and "R5" is input as the color and brightness in step S3, 70% by mass of hair coloring agent A and 30% by mass of hair curing agent B are identified as hair coloring agents for dyeing newly grown hair near the scalp, and 65% by mass of hair coloring agent A and 35% by mass of hair curing agent B are identified as hair coloring agents for dyeing newly grown hair other than near the scalp. On the other hand, if the dyeability is "easy to dye" and "R5" is input as the color and brightness in step S3, a formulation that will dye the hair a darker color with the same color is identified under the same conditions. In this case, for example, a hair coloring agent with the same formulation as for "normal" "R6," which is one level darker, is identified. For example, if the dyeability is "difficult to dye" and "R5" is entered as the color and brightness in step S3, a formula that will dye the hair a lighter color with the same color under the same conditions will be identified. In this case, for example, a hair coloring agent with the same formula as "normal" for "R4," which is one level lighter, will be identified.

[0035] 6(b) stores hair coloring agents 38 for dyeing the dyed portion of the hair near the scalp (previously dyed hair) and hair coloring agents 39 for dyeing the dyed portion of the hair other than the scalp (previously dyed hair), in association with the color and brightness of the undercolor 36 and the color and brightness of the dyed hair 37. Each of hair coloring agents 38 and 39 may store only one type of hair coloring agent, or may store the types, brands, product numbers, etc. of multiple hair coloring agents and their blending ratios.

[0036] In step S6, by referring to the hair coloring agent table 35, the type and composition of hair coloring agents for dyeing previously dyed hair near the scalp, and the type and composition ratio of hair coloring agents for dyeing previously dyed hair other than near the scalp, can be identified, corresponding to the color and brightness desired by the customer that has been input.

[0037] The amount of hair coloring agent to be used can be determined for each section of the hair (near the scalp, midsection, and ends) based on the hair length of each region of the diagram 50 entered in step S4. In step S4, the hair length can be determined from options such as "0-2 cm," "2-5 cm," "5-10 cm," "10-15 cm," "15-20 cm," "20-25 cm," and "25-30 cm." The amount of hair coloring agent to be used can be predetermined for each of these length options. For example, a correspondence between hair length and amount of hair coloring agent can be predetermined, such as 30 g for "2-5 cm," 40 g for "5-10 cm," and 50 g for "10-15 cm." This correspondence can be determined in advance, such that the amount of hair coloring agent used increases as the hair length increases. Alternatively, the amount of use may be calculated based on the length of the hair in accordance with a predetermined relational expression.

[0038] Once the amount of hair coloring agent used for each section of hair (near the scalp, the center, and the ends) has been determined, the amount of each hair coloring agent used can be calculated from the blending ratio of the coloring agents derived from a hair coloring agent table such as that shown in Figure 6 and the total amount of hair coloring agent used. For example, if the length of a certain section of hair is "2 to 5 cm" and the total amount of hair coloring agent used is specified as 30 g, and the blending ratio is 75% by mass of hair coloring agent A and 25% by mass of hair coloring agent B, then the amount of hair coloring agent A used will be 22.5 g and the amount of hair coloring agent B used will be 7.5 g.

[0039] In step S6, when the server device 2 identifies the hair coloring agent to be used, the server device 2 transmits the identified type and amount of hair coloring agent to the store terminal 1, and the identified type and amount of hair coloring agent to be used are displayed on the display screen of the store terminal 1 (step S7). Note that the identified amount of hair coloring agent to be used is a guideline, and the store clerk may use a smaller or larger amount.

[0040] The information entered in steps S2 to S5, and the type and amount of hair coloring agent used identified in step S6 are stored as a history for each customer in the store terminal 1 or the server device 2 along with the date of store visit (step S8). Note that the amount of hair coloring agent actually used by the store clerk for hair dyeing may differ from the amount of hair coloring agent used identified in step S6. Therefore, if the amount of hair coloring agent actually used for hair dyeing is entered into the store terminal 1, the entered amount can be stored in the store terminal 1 or the server device 2.

[0041] Here, the previously dyed portion of hair refers to a portion that has been previously dyed by coloring. The previously dyed portion discolors over time since the dyeing, and may become lighter or darker than the original color. Therefore, the store clerk makes a judgment by observing the condition of the previously dyed portion of the hair of the person to be dyed. Typically, the previously dyed portion of hair is located away from the head, and is less susceptible to the influence of the person's body temperature during dyeing. Therefore, if the previously dyed portion is lighter than the original color, the hair coloring agent for dyeing the previously dyed hair other than near the scalp can be identified by referring to the hair coloring agent for dyeing new hair other than near the scalp. For example, if a hair coloring agent corresponding to "R5" is identified in step S6, and the hair in the dyed parts of the person to be dyed is lighter than the original color, a hair coloring agent corresponding to "R6", which is a color darker than "R5", can be displayed as recommended, and if the hair in the dyed parts of the person to be dyed is darker than the original color, a hair coloring agent corresponding to "R4", which is a color lighter than "R5", can be displayed as recommended.

[0042] The hair coloring agent identification process ends with the processing of steps S1 to S8. While checking the display screen of the store terminal 1, the store clerk can select and mix a hair coloring agent for dyeing new hair near the scalp, a hair coloring agent for dyeing new hair other than near the scalp, a hair coloring agent for dyeing previously dyed hair near the scalp, and a hair coloring agent for dyeing previously dyed hair other than near the scalp. By using this hair coloring agent identification system, hair coloring agents can be accurately mixed, which has previously relied on the hairdresser's sense, preventing problems such as dyeing the customer's desired color or uneven coloring of the dyed hair.

[0043] In the above embodiment, the hair coloring agent identification system is composed of a store terminal 1, a server device 2, and a communication network 3, and the hair coloring agent identification process is executed by the store terminal 1 and the server device 2. However, for example, the hair coloring agent identification system can also be configured to be composed of a single computer device, and the hair coloring agent identification process can be executed by that single computer device.

[0044] The hair coloring agent identification system of the present invention can be applied not only to dyeing hair color, so-called "fashion dyeing," but also to "gray hair dyeing," which dyes gray hair black.

[0045] When dyeing hair, for example, if the hair of a customer who is to be dyed does not have any previously dyed portions, the hair can be classified into two categories: newly grown hair near the scalp and portions other than the scalp. Also, for example, if the hair of a customer who is to be dyed has previously dyed portions, the hair can be classified into three categories: newly grown hair near the scalp, newly grown hair other than the scalp, and previously dyed hair other than the scalp.

[0046] Figure 7 shows an example of hair to be dyed according to an embodiment of the present invention. Hair 40 in Figure 7(a) is composed of new hair 41 near the scalp and new hair 42 other than the scalp. Hair 40 in Figure 7(b) is composed of new hair 41 near the scalp, new hair 42 other than the scalp, and previously dyed hair 43 other than the scalp.

[0047] Conventionally, these two or three portions have been dyed using the same hair coloring agent. For example, in the case of Figure 7(a), a hair coloring agent is applied to the new growth hair 42 other than the portion near the scalp, and after a period of time, the same hair coloring agent is applied to the new growth hair 41 other than the portion near the scalp. In the case of Figure 7(b), a hair coloring agent is applied to the new growth hair 42 other than the portion near the scalp, and after a period of time, the same hair coloring agent is applied to the new growth hair 41 other than the portion near the scalp, and then the same hair coloring agent is applied to the previously dyed hair 43 other than the portion near the scalp.

[0048] On the other hand, according to the hair dyeing method of the present invention, in the case of Figure 7(a), a hair coloring agent is applied to new growth hair 41 near the scalp, and then, immediately, without a predetermined time, a hair coloring agent is applied to new growth hair 42 other than near the scalp. In the case of Figure 7(b), a hair coloring agent is applied to new growth hair 41 near the scalp, and then, immediately, without a predetermined time, a hair coloring agent is applied to new growth hair 42 other than near the scalp, and then, immediately, without a predetermined time, a hair coloring agent is applied to previously dyed hair 43 other than near the scalp. After these applications of the hair coloring agent are completed, a certain time is waited and the hair coloring agent is washed off the hair, completing the hair dyeing.

[0049] The hair coloring agent applied to the new growth hair 42 other than the area near the scalp is a hair coloring agent corresponding to the color and brightness desired by the customer. The hair coloring agent applied to the new growth hair 41 other than the area near the scalp is a hair coloring agent that, when applied to hair in the same condition, will dye the hair the same color but darker than the hair coloring agent applied to the new growth hair 42 other than the area near the scalp. This prevents uneven coloring of the dyed hair, even if the hair coloring agent is applied starting from the roots without any waiting time. The type and amount of hair coloring agent used in this case can be the type and amount of hair coloring agent identified by the hair coloring agent identification system described in the above embodiment.
