Full Description:
This case is a continuation of application Ser. No. 12/010,024 Method and Apparatus for Coloring Hair, filed Jan. 18, 2008 now abandoned related to Salon Operating System Ser. No. 10/970,161 filed Mar. 3, 2004 which is based on provisional application 60/491,519 filed Aug. 1, 2003. 
    
    
     FIELD OF THE INVENTION 
     This invention relates to the field of automated controls for the hair coloring industry, and more specifically to an apparatus and method of calculating proportional amounts of hair coloring solutions for use on a measured panel of hair of a customer 
     BACKGROUND OF THE INVENTION 
     The hair coloring industry sells products on the retail and commercial levels in bottles and dispensers. For most hair salons, the use and sales of the products are monitored by inventory controls such as software accounting packages designed for salons. As each customer is treated with hair coloring solution, each leftover bottle of solution is stored or thrown away. The amount used per application for each customer is based on the amount dispensed by the salon employee. 
     An enormous amount of color waste is generated in today&#39;s salon due to the over mixing of color. This practice has a negative impact on the financial health of a salon and a negative affect on the environment. By reducing waste levels to zero waste, the profit margins of the business automatically grow, thus resulting in increased profitability. Waste is turned into real dollars and a healthy bottom line. With the rising costs of operating expenses, there exists a need in the salon industry for controlling the amount of solution for each individual. 
     There have been attempts to control the amount of hair coloring solution per application by providing single shot dispensers pumps. There have been patents for on site formulation of hair dye shades and shampoos as disclosed in Louise et al U.S. Pat. No. 5,316,481 and Hirsch et al U.S. Pat. No. 5,643,341. Measuring systems for effecting hair color are disclosed in MacFarlane et al U.S. Pat. Nos. 5,671, 735, 6,067,504, 6,314,372, 6330,341. 
     A hair coloring calculator is described in the patent to Scott U.S. Pat. No. 4,434,467. Scott provides a display which allows an individual to pick a hair color and the particular product line. However, there are no systems directed to a hair coloring method designed to save coloring solution from waste. 
     There exists a need in the salon industry for a global system used to control the amount of hair coloring dispensed for each customer based on the customer&#39;s need prior to treatment. There is a further need for a universal language in the hair coloring industry for communicating with salon employees and customers regarding each part of the head and the amount of color applied to the hair. A hair coloring system needs to be a controlled application method for calculating and applying a limited amount of solution to the hair of each individual based on area and color.

     DETAILED DESCRIPTION OF THE INVENTION 
     The present invention is directed to an automated apparatus for determining the amount of each solution used to prepare a customized coloring solution for a customer having their hair colored or highlighted. More specifically, the present invention is directed to an automated control console which calculates the amount and cost of each solution as it is formulated to provide a color stylist with precise measurements and price without typing or writing. 
     With reference to  FIG. 1 , a schematic drawing illustrating a network for using a Color Management System is illustrated. A central processing unit  1  is remotely located from a plurality of salons ( 4 - 8 ) but is connected by way of the Internet for purposes of communicating with each salon. The central processing unit includes means for reviewing data accumulated by a memory at each salon and means for assisting each salon with the data as part of a managing system. 
       FIG. 2  discloses a typical station at a hair salon, including a desk top, with a display  10 . The display is typically a touch screen panel for use with a hard drive for running salon software, preferably, SALONBIZ®. This type of software is used to schedule appointments, keep tract of inventory and beauty specialists. Each desk top is in communication with the central processing unit  1 . 
       FIG. 3  discloses a color treatment system  20  of the present invention. The color treatment system of the present invention includes at least one or more color treatment stations  21 - 29 , each having a color treatment display  30 - 38  each connected to a color treatment memory located in a hard drive at each color treatment station. Software, sold under the trademark COLORBIZ® is used to manage and operate the use of color bleach solutions, developers and color tones for each customer. The software further calculates the amount and cost of each solution per customer to formula a precise customized hair make over for each customer. 
     As each new customer makes an appointment, an identity is generated in the salon operating software and in the software used to operate and manage the amount and cost for each solution. A color specialist will typically start by pulling up the screen shot as shown on  FIG. 3  which is a screen shot of a color display page listing appointments on the top bar line followed by today&#39;s appointments which provides the color specialist with means for entering a customer&#39;s name into the system along with an appointed color specialists listed under staff name. Column 3 lists a start time for each customer to begin the color treatment process. The display below today&#39;s appointments lists checked in appointments for those customers who have already began the process. After check-in, an options icon  40  on the right side permits the color specialist to prepare the customized coloring process without leaving the display or typing or writing any amounts. 
       FIG. 4  illustrates the first step in preparing a customized color treatment ticket. The screen shot illustrated in  FIG. 4  discloses a system configuration with column 1 listing personal information of the customer who is under review. Column 2 provides additional information on the customer regarding hair length. Hair length is divided into four categories, short, medium, long and extra long. An icon for each category is provided on the display. A standardized table is provided to present a pre-selected volume of hair corresponding to each customer as entered on the display. The volume of hair, as indicated by each length, is used in a formula to determine an amount of each of the other solutions used to color the customer&#39;s hair. 
       FIG. 4  further illustrates in column 1, a series of icons after the print line including service names, bowl formulas, duration, price, next visit and color specialist. Under columns 1-2, is a horizontal bar line followed by view system, view services, view high lights, view staff and view color lines. On the right side of  FIG. 4 , a System Defaults column shows that the system default is set on long hair. Icon bars illustrating Service Levels, Staff and Color Lines are presented at the bottom of the System Defaults column. This screen shot is the View System shot. 
     Selecting the view services shot shown in  FIG. 4 , presents the screen shot shown in  FIG. 5  which is the basic services menu. New growth box  51 , color balance box  61 , color tone box  71  and color cleanse box  81  are next presented to the color specialist for selecting each type of service. For example, new growth formula box  52  provides the color specialist with an entry for new hair growth since the last visit. Coloring new hair requires a different calculation than one for previously colored hair. New growth price box  53  computes the price based on the amount of color bleach added in new growth formula box  52 . Color balance box  61  provides a selection of the four hair lengths and the cost based on the selection. Color tone box  71  and color clease box  81  further provide the color specialist with more options and prices based on the services requested by the customer, all based on hair length. Further shown in  FIG. 5  are highlight procedures and selection icons for in between foils new growth  92  and in between foils color balance  93 . 
     Display shot in  FIG. 6  illustrates the possibilities of selections for base color, tones, or other ingredients. Also provided is a developer amount options page for the user to select and use a calculated amount of developer. 
       FIG. 7  illustrates a diagram using an algorithm particularly designed for preparing a formula based on the parameters of the customer&#39;s hair. Start  200  begins the user&#39;s input of area of application. The data for the amount of the base color is retrieved at  202  and at  203  the user inputs the base amount from the standard formula or selects a standard formula and the based amount is retrieved. Next, at  204 , a reduction/increase factor is computed (f=b/a). Other ingredient standard amounts are input or retrieved from a selected standard formula (i) at  205 . Then, at  206 , a corrected ingredient amount based on application area of the hair and head is computed and if no other ingredient is necessary  207 , the final solution product amount is computed, entered and dispensed. If another ingredient is necessary, that amount is entered in the formula for processing. The algorithm for the reduction or increase of standard color formula is based on predefined application area base color amounts. 
     Using the following computations, wherein: 
     a=Base amount required for color application area (retrieved from a table) 
     b=Base amount in standard stored or colorist entered formula 
     f=Reduction/Increase factor 
     i=Amount of any other ingredient 
     c=Corrected ingredient amount based on application data. 
     The algorithm for the reduction or increase of standard color formula is based on predefined application area base color amounts. The colorist or user indicates the area of the head to be colored for this particular service. The user indicates the base amount (a standard non-optimized color formula amount (b 1 ) this is either manually entered by the colorist or the colorist chooses from a selection of stored formulas. The amount b 1  is based on standard formula amounts and does not vary based on application area. Based on the area of the head and the type of base color chose the optimal amount of base color necessary to complete the service with minimum waste (c 0 ) is retrieved. There may be multiple bases used I order to make a split base. {b 1 , b 2 , . . . b n } Computing the formula modifier factor f={b 1 , b 2 , . . . b n }/(c 0 ) is done. Then this factor is applied to each of the bases to give the optimal quantity (o x ) for each base. The formula o x =b x *f is used to calculate the optimal quantity of each base. All additional ingredients (i x ) (either manually entered by the colorist or from a stored formula) have the same factor applied to arrive at p x , the proper portion size to create the optimized color formula amount. The formula p x =i x *f is applied to each additional standard ingredient amount. If at any time the non-optimized amounts are changed on any ingredient, calculations are redone to compute the optimal amount of each ingredient.
