Problems solved by technology

[0005] However, high temperature, overacid or overbase, strong oxidizing agents, heavy metals, high concentration of ions, etc. will destroy the stability of protein
The dye-containing agent (dye) of the hair dye contains more ionic raw materials at a high pH value; while the agent containing hydrogen peroxide (developer) of the hair dye contains a strong oxidizing agent at a low pH value, although the current Technology has developed many hydrolyzed proteins that are relatively stable under conditions such as high temperature, overacid or overalkali, strong oxidants, heavy metals, and high-concentration ions. If hydrolyzed proteins or their derivatives are added to these two hair dyes, the long-term During the storage process, some active ingredients will still change, resulting in reduced or invalid hair repair effect

Embodiment 1

[0040] This embodiment is a three-component hair dye, including the composition shown in Table 1 by weight percentage.

[0041] Table 1

[0042]

[0043]

[0044] The dyeing agent, developer and care agent are applied to hair dyeing with a weight ratio of 5:5:1 (the content of lauryl dimethyl ammonium hydroxypropyl hydrolyzed keratin is about 0.5%). The specific hair dyeing method is:

[0045] First add 30g of the coloring agent and 30g of the color developing agent into the mixing bottle and tighten the cap, shake and shake for 5-8 times, so that the materials in the bottle are basically mixed evenly, then unscrew the bottle cap, add 6g of the care agent, Tighten the cap and shake it 5-8 times to make the materials in the bottle basically mixed evenly, then squeeze out the mixed hair dye from the bottle mouth, apply it to the hair, and stay on the hair for 20-30 minutes. If the temperature is low or If the hair is thick and difficult to color, it can be properly heated...

Embodiment 2

[0047] In this embodiment, a three-component hair dye comprises the composition shown in Table 2 by weight percentage.

[0048] Table 2

[0049]

[0050]

[0051] Apply the coloring agent, developer and care agent to hair dyeing with a weight ratio of 10:10:1 (the content of lauryl dimethyl ammonium hydroxypropyl hydrolyzed keratin is about 1.0%). The specific hair dyeing method is:

[0052] First add 30g of the coloring agent and 30g of the color developing agent into the mixing bottle and tighten the cap, shake and shake for 5-8 times, so that the materials in the bottle are basically mixed evenly, then unscrew the bottle cap, add 3g of the care agent, Tighten the cap and shake it 5-8 times to make the materials in the bottle basically mixed evenly, then squeeze out the mixed hair dye from the bottle mouth, apply it to the hair, and stay on the hair for 20-30 minutes. If the temperature is low or If the hair is thick and difficult to color, it can be properly heated, ...

Embodiment 3

[0054] This embodiment is a three-component hair dye, including the composition shown in Table 3 by weight percentage.

[0055] table 3

[0056]

[0057]

[0058] Apply the coloring agent, developer and care agent to hair dyeing with a weight ratio of 3:3:1 (the content of hydrolyzed keratin is about 1.5%). The specific hair dyeing method is:

[0059] Squeeze 30g of the dye and 30g of the developer into a mixing bowl, stir and mix evenly, add 10g of the conditioner, stir evenly, apply the mixed hair dye to the hair, and leave it on the hair 20-30min, if the temperature is low or the hair is rough and difficult to color, heat it properly, wait for the hair to reach the color effect, rinse with clean water, and dry the hair.

Abstract

The invention relates to a three-dosage form hair dyeing agent and a hair dyeing method. The three-dosage form hair dyeing agent comprises three agents and the three agents comprise a dyeing agent containing oxidation dye and an alkaline agent, a developer containing a strong oxidizing agent and a care agent. The care agent comprises, by weight, 5-35% of protein hydrolysate and / or protein hydrolysate derivative, 0-1.0% of an auxiliary agent and the balance a solvent. A weight ratio of the protein hydrolysate and / or protein hydrolysate derivative to the dyeing agent, the developer and the care agent is 0.2-2%. The three-dosage form hair dyeing agent breaks through the traditional hair dyeing product formula mode, provides the three-dosage form hair dyeing agent formula with individually packaged protein hydrolysate, solves the problem of easy effect loss of the protein in the prior art by preparation of the care agent containing protein hydrolysate and / or protein hydrolysate derivative according to a specific weight percentage, and realizes hair repair and care by protein in hair dyeing.

Description

technical field [0001] The invention relates to a hair dye, in particular to a three-component hair dye and a hair dyeing method. Background technique [0002] During the hair dyeing process, a large amount of alkaline substances enter the hair, destroying the original protein and amino acids, and the damage to the hair is inevitable. Therefore, the dyed hair usually becomes dry, dull and elastic. [0003] The hair color of Asians is mostly black or dark brown, because the cuticle of the hair has accumulated a large amount of melanin factors, and relatively speaking, Asians have thicker and thicker hair, so it is difficult to dye. hair type. From the principle of hair dyeing, to change the original color of hair, on the one hand, part of the inherent pigment of the hair must be faded, and on the other hand, some new pigment must be added. These two processes work at the same time to obtain the final effect. Hair dyes can dye light black hair, and usually contain hydrogen p...
