Although the single use of the polygonum multiflorum has certain effects of blackening, fixing and nourishing hair, the effect is often not ideal, and in addition, the anti-bacterial effect and the anti-inflammatory and anti-oxidation functions of the polygonum multiflorum extract are limited, so that the dandruff and itching relieving effect of the shampoo containing the polygonum multiflorum component is also poor. Dandruff and scalp itch are usually generated due to microbial activities, vigorous metabolism, inflammation and other reasons, and the traditional Chinese medicine contains a plurality of medicinal materials for clearing heat and removing toxicity, but is mostly used as one of compound components, and the effect is not obvious and is difficult to control. In the prior art, a technical method for improving the effects of removing dandruff and relieving itching by singly using heat-clearing and detoxifying traditional Chinese medicines and polygonum multiflorum in a compatible manner for preparing shampoo does not exist, so that the invention effectively improves the effects of removing dandruff and relieving itching by singly using scutellaria baicalensis and polygonum multiflorum in a combined manner for preparing the shampoo.

In the research and development process, other traditional Chinese medicinal materials with the effects of clearing heat and removing toxicity are respectively combined with the polygonum multiflorum, such as coptis chinensis, golden cypress, dandelion, honeysuckle and the like, the color development of the coptis chinensis is easily influenced due to the heavier color, the golden cypress, the dandelion and the honeysuckle have certain dandruff-removing and itching-relieving effects, and after the application, the scalp has a cool feeling, but the dandruff-removing and itching-relieving effects are not as obvious as those of the scutellaria baicalensis. In addition, although the garlic juice has good antibacterial and antioxidant effects, the garlic juice is not suitable for preparing shampoo due to heavy smell, and the cost and the process for separately extracting the allicin are high. In addition, although sulfur also has a certain antibacterial effect, the antibacterial and antioxidant effects are poor due to the single component, and sulfur belongs to a chemical raw material, and is not good for human bodies after long-term use.

The technical solution of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Comparative example 2

Compared with the example 1, the shampoo is prepared without adding the polygonum multiflorum extract, and is added with the scutellaria baicalensis extract with the same parts, namely the scutellaria baicalensis extract and the fermented rice washing water, and the rest are the same.

Comparative example 3

Compared with the example 1, the fermented rice washing water is not added in the shampoo preparation, and the same parts of water, namely the scutellaria baicalensis extract and the polygonum multiflorum extract are added, and the rest are the same.

Comparative example 4

Compared with the embodiment 1, the shampoo is prepared by adding the same parts of water and scutellaria baicalensis extract as the polygonum multiflorum extract into the fermented rice washing water and the polygonum multiflorum extract instead of the fermented rice washing water and the polygonum multiflorum extract, namely only the scutellaria baicalensis extract is contained, and the rest is the same.

Comparative example 5

Compared with the embodiment 1, the shampoo is prepared by adding the same parts of water and the same parts of polygonum multiflorum extract as the fermented rice washing water and the same parts of scutellaria baicalensis extract instead of adding the fermented rice washing water and the scutellaria baicalensis extract in the preparation of the shampoo, namely only the polygonum multiflorum extract is contained, and the rest are the same.

Effect verification

Selecting 75 male evaluation personnel with hair length of more than 10cm, wherein the male evaluation personnel are 25-40 years old, all the selected evaluation personnel have the problems of white hair, scalp itching and more scurf, the white hair number accounts for more than 20%, the scalp itching frequency is more than 10 times each time, the evaluation personnel are divided into 5 groups, 15 people in each group use the shampoos prepared in the embodiment 1, the comparative example 2 and the comparative example 3 respectively, the shampoos are used 1 time every other day, the shampoo is used in an amount of 5-10 mL, and each massage and rubbing is carried out for 5-10 min. After three months of use, the evaluation was performed on the degree of hair blacking, the antipruritic effect, and the antidandruff effect, and the evaluation was classified into 3 grades, 0: no effect is obtained; 1: has partial effect; 2: has obvious effect.

The evaluation criteria of the degree of blackness are:

0: the white hair quantity ratio is still over 20 percent, and the white hair quantity ratio is not obviously reduced;

1: the white hair quantity accounts for less than 20 percent but still more than 5 percent, or the white hair quantity accounts for obviously reduced;

2: the white hair quantity is obviously reduced and is less than 5 percent.

TABLE 1 Hair blackness test results

	0	1	2	Total effective rate
					Example 1	1	4	10	93％
Comparative example 1	3	7	5	80％
					Comparative example 2	11	4	0	27％
Comparative example 3	5	6	4	67％
					Comparative example 4	15	0	0	0％
Comparative example 5	9	5	1	40％

From table 1, it can be seen that the scutellaria baicalensis extract alone has no effect on hair blackening, the polygonum multiflorum extract alone has no ideal hair blackening effect, and the combination of the scutellaria baicalensis extract and the polygonum multiflorum extract can promote hair blackening, compared with comparative examples 3 and 5, it is presumed that the active ingredients in the scutellaria baicalensis extract can inhibit microorganisms, eliminate oxidative free radicals, resist the factors generated by white hair, and generate a synergistic effect with the components in polygonum multiflorum for promoting hair blackening, so that the hair blackening effect of the polygonum multiflorum extract is further enhanced. The hair-blackening effect of comparative example 1 is better than that of comparative example 4, and the effect is remarkably improved by combining the polygonum multiflorum extract, probably because the fermented rice-washing water has the hair-blackening effect.

The evaluation criteria of the anti-dandruff effect are as follows:

0: there was no significant reduction in dandruff compared to before;

1: there was a reduction in dandruff compared to before, but dandruff was still visible;

2: dandruff is hardly or not visible at all.

TABLE 2 dandruff removal test Effect

	0	1	2	Total effective rate
					Example 1	0	1	14	100％
Comparative example 1	10	4	1	33％
					Comparative example 2	5	4	6	67％
Comparative example 3	3	5	7	80％
					Comparative example 4	6	4	5	60％
Comparative example 5	14	1	0	7％

According to table 2, it can be seen from comparative example 5 that the scurf removing effect of the polygonum multiflorum extract is not good, and from comparative example 4 that the scutellaria baicalensis extract has a certain scurf removing effect, and from comparison of comparative example 3 with comparative examples 4 to 5, the scurf removing effect of the polygonum multiflorum extract and the scutellaria baicalensis extract is obviously improved after combined use. Comparing example 1 with comparative example 3, it can be seen that the fermented rice-washing water can further improve the anti-dandruff effect of the scutellaria baicalensis extract and the polygonum multiflorum extract.

The evaluation standard of the itching relieving effect is as follows:

0: the scalp pruritus times are not obviously reduced compared with the prior art, and the scalp pruritus times per day are 10 times or more;

1: the scalp pruritus times are reduced compared with the prior scalp pruritus times, but the scalp pruritus times still appear for a plurality of times every day, and the appearance times are more than 2 times and less than 10 times;

2: the scalp itching problem hardly occurs any more, and the frequency of occurrence of scalp itching is 2 times or less.

TABLE 3 antipruritic degree test Effect

	0	1	2	Total effective rate
					Example 1	0	1	14	100％
Comparative example 1	11	3	1	27％
					Comparative example 2	4	8	3	73％
Comparative example 3	3	2	10	80％
					Comparative example 4	4	4	7	73％
Comparative example 5	13	2	0	13％

According to table 3, it can be seen from comparative example 5 that the itching relieving effect of the polygonum multiflorum extract is very poor and almost no itching relieving effect is obtained, from comparative example 4 that the itching relieving effect of the scutellaria baicalensis extract is obvious, and from comparative example 3 compared with comparative examples 4-5, the itching relieving effect of the scutellaria baicalensis extract and the polygonum multiflorum extract is further improved after combined use, probably because the antibacterial and antioxidant effects of the scutellaria baicalensis extract are good, and the antibacterial and antioxidant functions of the scutellaria baicalensis extract are further improved after combined use with the polygonum multiflorum extract. As can be seen from comparison of example 1 with comparative example 3, the effect of relieving itching can be further improved by adding the fermented rice-washing water.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
