Embodiment 1

[0050] A hair dyeing method based on the principle of surface coating, the concrete steps are as follows:

[0051] (1) Preparation of pre-staining agent

[0052] Add a given quality of pre-dye and biocompatibility additives into deionized water, adjust the pH to 8.0, and stir evenly to obtain the pre-dye. The pre-dye is best prepared and used immediately. Months, if the color becomes brown or black, it will be invalid; the components and their contents in the pre-staining agent are as follows:

[0053] Tris-HCl 0.1wt%, baking soda 0.2wt%, norepinephrine 0.5wt%, panthenol 0.5wt%, D-dopa 0.1wt%, olive oil 0.2wt%, the rest is deionized water;

[0054] (2) Preparation of dyeing agent

[0055] A given quality of coloring agent and corresponding additives are added to deionized water, and adjusted to pH = 8.0, and the coloring agent can be prepared after stirring evenly. The coloring agent can be stored for a long time under refrigerated conditions; each group in the coloring agen...

Embodiment 2

[0061] A hair dyeing method based on the principle of surface coating, the concrete steps are as follows:

[0062] (1) Preparation of pre-staining agent

[0063]Add a given quality of pre-dye and biocompatibility auxiliaries or just pre-dye into deionized water, adjust the pH to 5.8, and stir evenly to obtain the pre-dye. The pre-dye is best prepared and used immediately. It can be stored for half a month under the same conditions, and it will be invalid if the color turns brown or black; the components and their contents in the pre-staining agent are as follows:

[0064] Epinephrine (pre-dye) 0.2wt%, a-methyl dopamine 0.5wt%, L-dopa 10wt%, panthenol 0.5wt%, dopamine 0.1wt%, olive oil 0.2wt%, coconut oil 0.3wt%, glycerin 0.5wt%, squeezed lemon juice 0.5wt%, cornstarch 0.8wt%, konjac flour 0.1wt%, and the rest is deionized water;

[0065] (2) Preparation of dyeing agent

[0066] A coloring agent of a given quality and corresponding auxiliary agents are added to deionized wat...

Embodiment 3

[0072] A hair dyeing method based on the principle of surface coating, the concrete steps are as follows:

[0073] (1) Preparation of pre-staining agent

[0074] Add a given quality of pre-dye and biocompatibility auxiliaries or just pre-dye into deionized water, adjust the pH to 7.4, and stir evenly to obtain the pre-dye. The pre-dye is best prepared and used immediately. It can be stored for half a month under the same conditions, and it will be invalid if the color turns brown or black; the components and their contents in the pre-staining agent are as follows:

[0075] 5-Hydroxydopamine Hydrochloride 2wt%, Panthenol 0.5wt%, Coconut Oil 0.3wt%, Konjac Flour 0.1wt%, Carmellose Sodium 0.1wt%, Xanthan Gum 0.2wt%, the rest is phosphate buffer solution (PBS);

[0076] (2) Preparation of dyeing agent

[0077] A given quality of coloring agent and corresponding additives are added to deionized water, and adjusted to pH = 7.4, and the coloring agent can be prepared after stirrin...

Abstract

The invention relates to a hair dyeing method based on the principle of surface coating. Firstly, a pre-dyeing agent is used to pre-dye the hair surface to form a pre-dye layer, and then the pre-dye layer is dyed; the specific process of pre-dye is as follows: pH = 5 The pre-dye of ~11 is applied to the washed and dried hair, washed and dried after being kept for a period of time under natural environmental conditions; the pre-dye contains a pre-dye, and the pre-dye is tyrosine with a catechol functional group One or more compounds in natural-like compounds, and / or one or more compounds in their derivatives, and / or one or more compounds in the corresponding salts. The invention adopts the pre-dye which has no damage effect on the hair, and the dyeing agent is coated on the pre-dyed layer after forming the pre-dyed layer, which does not damage the structure of the hair itself, and has the advantages of mild dyeing conditions, safety, no stimulation, simple operation and dyeing color Natural, good durability and other advantages.

Description

technical field [0001] The invention belongs to the field of hair dyeing, and relates to a hair dyeing method based on the principle of surface coating, in particular to a strong adhesion ability of the non-toxic, harmless and non-irritating natural pre-dye itself on the hair surface and various A method for achieving permanent coloring of hair through the interaction of dyes. Background technique [0002] Melanin is a kind of biological pigment, which usually exists in the form of polymer. Tyrosine is hydrolyzed by tyrosinase to generate dopa, which is converted into indole quinone through oxidation, decarboxylation and other reactions, and finally indole Quinone polymerizes into melanin. When the medulla of hair, the melanin granule of cortical part reduces, disappears, and all or part of hair will turn white. The appearance of gray hair is a frustrating thing especially for teenagers and middle-aged people. Therefore, many people begin to use hair dyeing to cover up gra...
