[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye composition containing a natural dye as a main component and a hair dyeing method using the hair dye composition.

[0002]

2. Description of the Related Art Hair dyeing using natural dyes has been known for a long time, and henna and chamomile have been used. But,
In recent years, synthetic dyes, especially oxidation dyes such as p-phenylenediamine, have been favorably used because of their excellent hair dyeing power and versatile color tone, and hair dyes using natural dyes have been mostly used. Is gone.

[0003]

However, due to the diversification of hair styles, the hair is frequently treated with hair dyes, bleaching agents, permanent waving agents, hair straighteners, etc., and the hair is damaged accordingly. There was a problem that it became easy to receive.

Therefore, hair dyes using natural dyes that do not burden the hair have been reviewed, but no satisfactory hair dyeing power has been obtained.

[0005]

Means for Solving the Problems The present inventor has conducted intensive studies in view of the above-mentioned circumstances, and as a result, a powdery or granular first agent containing a powder obtained from henna and a water-soluble powdery polymer, It has been found that a hair dye composition comprising a second agent containing an acid provides good hair dyeing power, increases hair strength, and improves the feel and luster of hair, thereby completing the present invention. Reached.

That is, the present invention comprises (a) a powder obtained from henna, (b) a powdery or granular first agent containing a water-soluble polymer, and a second agent containing an acid. It is intended to provide a hair dye composition characterized by the above. Hereinafter, the present invention will be described in more detail.

[0007]

Further, the composition of Example 1 was applied in the same manner as described above, and then water was sprayed during the standing time, as Example 13, wherein the first and second agents of Example 1 were 1: 2 and 1: Hair dyeing tests were carried out as Examples 14 and 15 using the mixture at a weight ratio of 20 respectively. About the obtained dyed hair bundle, the hair dyeing power was visually evaluated according to the following criteria. ：: Uniform and deeply dyed, white is not conspicuous ○: Uniformly dyed, white is not conspicuous △: Dyeing is slightly non-uniform, white is slightly conspicuous ×: Dyeing is non-uniform, white is conspicuous

<Hair Strength> The yield stress value of the dyed hair bundle was measured using a tensile tester (Tensilon UTM-II; manufactured by Toyo Baldwin Co., Ltd.), and the yield stress value of the untreated hair bundle was defined as 100. The relative value was calculated and taken as the hair strength.

<Feel> Sensory evaluation of the feel and luster of the above-mentioned dyed hair bundle was made by a specialized panelist according to the following criteria. ◎: very good ：: good △: slightly bad ×: bad The above results are shown in Table 3.
