Aiming at the health problems of the hair and the scalp which are concerned, the development of the hair care product with the nourishing and nursing functions for the hair and the scalp is of great significance.
Tricholoma matsutake (Tricholoma matsutake), the subject name Tricholoma matsutake, armillariella matsutake, syzygium, and Theragra, belonging to the family Tricholomataceae, and belonging to the phylum Basidiomycotina, is a mycorrhizal fungus of the exogenesis of trees such as Quercus matsutake. The tricholoma matsutake has unique aromatic flavor, is a wild edible and medicinal fungus rich in various nutrients and functional active ingredients, and has various physiological functions of resisting tumor, enhancing immunity, controlling blood sugar, reducing cholesterol and blood lipid level, and the like. In recent years, due to the destruction and unscientific excavation of forest vegetation, the growth environment of tricholoma matsutake is seriously destroyed, and the requirement of the tricholoma matsutake on the growth environment is relatively high, so that the yield of wild tricholoma matsutake is reduced, and the supply is not required. At present, tricholoma matsutake mainly comes from wild picking, and because the tricholoma matsutake belongs to living symbiotic bacteria, the artificial culture of the tricholoma matsutake is very difficult.
The tricholoma matsutake is rich in various nutritional ingredients, can be used for repairing hair injury, cannot be applied to the field of hair repair on a large scale due to high cost of wild tricholoma matsutake, and at present, although some tricholoma matsutake is artificially cultured, the variety and content of active ingredients of the tricholoma matsutake are greatly reduced compared with those of the wild tricholoma matsutake, so that the application value of the tricholoma matsutake is influenced. Therefore, the development of the tricholoma matsutake strain with higher content of active ingredients and excellent growth performance under the artificial culture condition is of great significance for realizing the application of the tricholoma matsutake in the cosmetic fields such as hair restoration and the like.

Wherein the composition of the shampoo base was the same as that of the shampoo base in example 4.
Comparative example 2 shampoo base
This comparative example provides a shampoo base having the same formulation as the shampoo base of example 4.
Experimental example Hair restoration function detection of Tricholoma matt35 fermentation product
The shampoo of example 4 and comparative example 1 and the shampoo base of comparative example 2 were subjected to hair restoration function test, and the test method and test result were specifically as follows:
1. experiment of damaged effect of shampoo on repairing damaged hair and external hair scales
Healthy hair of volunteers is selected, washed by a sodium dodecyl sulfate solution, rinsed and naturally dried for later use. Taking 4 parts of intact hair, 10g each, soaking with 0.5g/L NaOH at 30deg.C for 1 hr, taking out, rinsing to neutrality, and naturally air drying to obtain damaged hair.
The shampoo of example 4 and comparative example 1 and the shampoo of comparative example 2 were used to wash damaged hair, the shampoo amount was 0.5g, the washing time was 3min, and the hair was rinsed with clear water and naturally dried.
The untreated (blank) and shampoo-washed hair bundles were immersed in a 0.2mol/L copper sulfate solution for 15min, respectively, and then the amount of copper ions adsorbed by the hair was measured.
TABLE 3 copper ion adsorption quantity
Note that: * P <0.05, P <0.01, P <0.001vs. blank.
When hair is damaged, the hair is negatively charged to absorb copper ions, and the hair damage degree can be characterized by measuring the copper ion absorption amount of the hair. The greater the degree of hair damage, the more copper ions are adsorbed. As can be seen from table 3, the copper ion adsorption amount of hair treated with shampoo was significantly reduced compared with the blank, while the copper ion adsorption amount of hair treated with shampoo containing tricholoma matt35 fermentation was significantly reduced compared with the shampoo containing tricholoma matt35 fermentation, indicating that the tricholoma matt35 fermentation has a more significant repair effect on hair external hair scale damage.
2. Hydrophilic-lipophilic test for repairing damaged hair by shampoo
30 volunteers subjected to dyeing and scalding within three months are selected, the hair contact angle (dry hair is 68-72 degrees, wet hair is 66-70 degrees) of each volunteer is tested, the volunteers are randomly divided into 3 groups, 10 people in each group are collected, the hair of each volunteer is recorded as a blank group, the damaged hair is respectively cleaned by using the shampoo of the example 4 and the shampoo of the comparative example 1 and the shampoo of the comparative example 2, 3 times per week, the hair of each volunteer is collected once per week, after the 3-week experiment is finished, the hair of each group is inserted into water in two states of dry hair and wet hair by adopting a Wilhelmy balance method, and the contact angle of water on the hair surface is calculated according to the received force, and the result is shown in Table 4.
TABLE 4 Hair contact angle
Note that: * P <0.05, P <0.01, P <0.001vs. blank.
The degree of hair damage is directly related to the hydrophilic and hydrophobic properties of the hair surface, and the greater the degree of hair damage, the greater the hydrophilicity of the hair. After the liquid spreads on the solid surface, the solid/liquid interface passes through the liquid interior to the gas/liquid interface, which is called the contact angle. The smaller the contact angle of water on the hair surface, the easier the spreading and the more hydrophilic. As shown in table 4, the contact angle of hair was remarkably increased by using the shampoo of example 4, compared with the hair dyed and scalded (blank group), and it was statistically significant (P < 0.05), indicating that the tricholoma matt35 fermented product of tricholoma matsutake strain was capable of remarkably repairing hair damage and restoring the hydrophilic and lipophilic properties of hair.
3. Influence of shampoo restoration on hair comb properties
The effect of shampoo restoration of example 4 on hair combability was analyzed as follows:
30 volunteers subjected to dyeing and scalding within three months are selected, randomly divided into 3 groups, 10 volunteers are collected for hair leave-out before the test starts, each group of volunteers is respectively washed by using shampoo of example 4 and comparative example 1 and shampoo matrix of comparative example 2, used for 1 week and used once every other day, and hair of each volunteer is collected after the test is finished.
The collected hair is washed by tap water, the towel is used for wiping off redundant water until the hair bundle is free from dripping, the hair bundle is combed smoothly by a comb, and the wet hair combability is tested by a tension tester. The test results are shown in fig. 2.
Then, the hair is blown to be semi-dry by a blower at a distance of 20cm from the hair bundle, the hair is combed smoothly by a comb, the hair is naturally dried, and the combability of the dry hair is tested by a universal tensile tester. The test results are shown in FIG. 3.
The results show that the shampoo of example 4 has significantly better combing properties (wet combing and dry combing) on hair than the shampoo containing the fermentation broth of Tricholoma matsutake strain T35 (comparative example 1) and the shampoo base (comparative example 2).
4. Shampoo repair dyeing and scalding damaged hair effect experiment
To verify the effect of the shampoo of example 4 on repairing and scalding damaged hair, 30 volunteers who had been dyed and scalded in the age of 25-60 years and had suffered a certain damage to hair during the dyeing and scalding process were selected, and were randomly divided into 3 groups of 10 persons each, and the shampoo of example 4, the shampoo of comparative example 1 and the shampoo base of comparative example 2 were provided for 2 months at a frequency of once every two days, and the effects of the shampoo on repairing the internal structure of hair and strengthening hair were examined. Volunteers measured maximum force and work of breakage of hair before the start of the experiment, measured maximum force and work of breakage of hair after 2 months using shampoo, and compared to changes in hair strength. Hair strength was tested using a Diastron tensiometer.
TABLE 5 variation of hair breaking strength
The results are shown in Table 5, and the maximum force of hair breakage and breaking work are significantly increased after the shampoo of example 4 compared with the shampoo before the use, which indicates that the fermentation product of Tricholoma matt35 strain can significantly repair the internal structure of hair and improve the hair strength.
