Hair coloring method

Abstract

A method for coloring hair on a human head using a blow dryer is provided. According to the method, the hair is separated into sections of different shape (e.g., rhombic, square, triangular, horseshoe-shaped, etc.). Then, subsections of hair are isolated in each section. Each subsection of hair is grabbed and pulled (in a direction of a cut line of the hair) with one hand of a hairdresser, and different (e.g., short, medium-length, and long) layers of hair are blown out of the subsection of hair by an air flow from the blow dryer held in another hand of the hairdresser. After that, at least one of the blown-out layers of hair is fixed (e.g., with a clamp) and colored. The hair thus colored is then rinsed and treated according to a post-coloring recipe.

1 . A hair coloring method comprising the following steps performed by a hairdresser:
 separating hair on a head of a person into sections by parting the hair based on anatomical points of the head;   in each of the sections of the hair, isolating subsections of hair based on a direction of hair growth in the section, each of the subsections of hair comprising a layer of long hair and a layer of short hair;   for each of the subsections of hair:
 grabbing the subsection of hair with one hand close to an end of the layer of long hair; 
 holding a blow dryer in another hand and directing an air flow from the blow dryer through the subsection of hair, while pulling away the subsection of hair in a direction of a cut line of the hair, thereby gradually blowing the layer of short hair out of the subsection of hair; 
 fixing each of the layer of long hair and the layer of short hair with a clamp; 
 sequentially removing the clamps and coloring the layer of long hair and/or the layer of short hair by using a color formula; 
 wrapping the colored layer of long hair and/or the colored layer of short hair in a foil; and 
 upon expiry of a time period prescribed for the color formula, removing the foil from the colored layer of long hair and/or the colored layer of short hair; 
   rinsing the color formula off the hair, and   treating the hair according to a post-coloring recipe.   
     
     
         2 . The method according to  claim 1 , wherein said coloring by using the color formula comprises applying at least two different colors to the layer of long hair and/or the layer of short hair. 
     
     
         3 . The method according to  claim 2 , wherein said coloring by using the color formula comprises applying the color formula to the subsections of hair in a form of a horizontal or zigzag pattern. 
     
     
         4 . The method according to  claim 1 , further comprising, after said rinsing the color formula off the hair but before said treating the hair according to the post-coloring recipe, tinting each of the subsections of hair. 
     
     
         5 . The method according to  claim 1 , wherein said coloring by using the color formula is performed in accordance with a graphic coloring scheme which shows the layer of long hair in the subsection of hair as a first triangle and the layer of short hair in the subsection of hair as a second triangle, the first triangle having a base representing a root hairline and an apex representing an end of the subsection of hair, and wherein the second triangle is smaller than the first triangle and is shown in the graphic coloring scheme as extending beyond the first triangle, and wherein the graphic coloring scheme further shows a border of a root zone, boundaries of coloring areas, and the color formula to be applied in each of the first triangle and the second triangle.
