Comparative example 4: a shampoo differing from example 7 in that: the shampoo does not contain sodium chloride.

Third, performance detection and analysis

Test one: grease index test subjects: the hair loss prevention shampoos prepared in examples 1 to 10 were used as test samples 1 to 10, and the shampoos prepared in comparative examples 1 to 4 were used as control samples 1 to 4.

The test method comprises the following steps: randomly selecting 2 shampoo shops in a certain area, randomly searching 7 consumers in each shampoo shop, not limiting men and women, respectively naming 16 consumers as X1-X16, respectively detecting corresponding grease indexes at the positions of the afterbrain curl and the top of the head of each consumer by using a CK skin tester, respectively washing the hair by using sample samples 1-10, comparison samples 1-4 and commercially available products 1-2, and drying the hair for 10min after washing the hair, and then detecting the grease indexes at the positions of the afterbrain curl and the top of the head again; the average values of the fat indexes at the back brain curl and the top head of the user were measured at intervals of 1 day in the form of giving shampoo, and are recorded in tables 2 to 5, respectively.

TABLE 2

TABLE 3

TABLE 4

TABLE 5

It can be seen from the combination of examples 1 to 10 and comparative examples 1 to 4 and the combination of tables 2 to 5 that examples 1 to 10 have a good control effect on the secretion of oil from the head skin, have a significant cleaning ability within 10 minutes of drying by air after the hair washing, and can effectively remove a large amount of oil stains in the hair follicles and garbage attached to the surface of the oil stains without a large amount of hair loss phenomenon apparently caused by the hair washing. Among them, the degreasing abilities of examples 7 to 10 were not greatly changed, and it was found that the cleansing ability of the head skin was well improved by adjusting the amounts and ranges of the respective components of the shampoo, particularly by adjusting the amounts and ranges of sodium laureth sulfate, cocamide MEA and cocamidopropyl betaine, and that the oil discharge amount of the hair 24 hours after using the shampoo was lower than the level before shampooing, and had a certain oil control effect, because the above-mentioned components had less irritation to the skin.

As can be seen by combining example 7 with comparative examples 1 to 3 and tables 2 to 5, the surfactant of comparative example 3 was only sodium laureth sulfate, and the scalp oil immediately after washing with the shampoo of comparative example 3 was low, so that it was seen that sodium laureth sulfate had better cleansing ability, but the irritation was large by adding only sodium laureth sulfate, and the amount of oil discharged from the hair after 24 hours was close to the level before washing the hair, and at the same time, hair loss was noticeable upon washing the hair. However, as can be seen by combining comparative examples 1-2 and example 7, the addition of either or both of sodium laureth sulfate, cocamide MEA, and cocamidopropyl betaine alone does not achieve the objectives of improved cleaning and enhanced oil control.

Combining example 7 and comparative example 4 with tables 2-5, it can be seen that the main difference between the addition of sodium chloride and the absence of sodium chloride is whether the cleanliness can be improved within 10min of blow drying after shampooing. Analysis shows that the cleaning capability of the added sodium chloride to the scalp surface is improved within 10min of drying after hair washing. However, in comparative example 4, after sodium chloride was not added, the cleaning ability of the scalp surface was lowered within 10min after shampooing, and at the same time, hair loss was remarkably generated during shampooing; however, the scalp after shampooing with the shampoo of comparative example 4 also aggravates the oil-out phenomenon of the scalp, thereby proving that the sodium chloride has the effect of controlling the water-oil balance of hair follicles between the formulation of the shampoo and other components.

And (2) test II: hair combing test subjects for hair: the hair loss prevention shampoos prepared in examples 1 to 10 were used as test samples 1 to 10, and the shampoos prepared in comparative examples 1 to 4 were used as control samples 1 to 4.

The test method comprises the following steps:

1. main experimental instrument

INSTRON 3343 model materials tester (NSTRON Corp.).

2. Experimental procedure

2.1 treat the hair into tresses of 50g weight and 27cm length, with 3cm upper end and 24cm lower end of the knot.

2.2 treating with tap water, repeating twice, and naturally drying.

2.3 put the hair into a PET plastic bottle of 150g containing ether, soak for four hours, repeat twice, and naturally dry.

2.4 Place the hair in the container 5g K₁₂Soaking in 1000ml beaker of tap water at 50-60 deg.C for two hours, and repeating twice.

2.5 rinsing with tap water until no foam is formed and combing until the hair does not drip.

2.6 hair strand shampoo treatment: respectively weighing 4g of test sample 1-10 and control sample 1-4, then respectively rubbing the hair strands to the treated hair strands until the foams are uniform, standing for 5 minutes, washing the hair strands with natural water until no foams exist, naturally airing, and carrying out wet combing test.

2.7 after the wet combing test is finished, naturally drying.

2.8 the hair is placed in an environment at 25 ℃ and 60% RH for 8 hours.

2.9 Dry combing tests were performed.

2.10 the results were calculated and recorded in table 6.

3. Testing operation steps of single-upright-column tension meter

3.1 the power supply of the host is turned on, and the instrument is preheated for more than half an hour.

3.2 click the remote key on the touch screen, and open the computer and the series IX software.

3.3 setting parameters:

the test direction is as follows: upwards;

stretching speed: 1000 mm/min;

sampling rate: a 100 second point;

absolute limitation: the high load level was 0.05KN and the high elongation was 250 mm.

3.4 balance beam.

3.5 displacement and load zeroing: firstly, adjusting the displacement to a proper lowest position, and then, zeroing; the load was adjusted to a certain height (so that the test specimen did not touch the fixed comb) and then zeroed.

3.6 fixing the hair sample to be tested with a suitable clamp.

3.7 test hair samples, repeat 5 times, take average value (program automatically record data, automatic save).

And 3.8 finally, the series IX software, the computer and the host are powered off.

4. Formula for calculation

The carding force reduction degree calculation formula is as follows:

wherein: CombingWork (blank): combing force of blank sample (before anti-hair loss shampoo treatment); CombingWork (sample): combing force of the hair loss prevention shampoo. The higher the combing force reduction degree is, the better the combing property is, the smaller the force is needed, namely the easier the combing is, the side surface shows that the mechanical broken hair is less, the hair root is strengthened and the hair loss prevention effect is achieved.

TABLE 6

As can be seen by combining examples 1-10 and comparative examples 1-4 with Table 6, the combing force reductions for both the wet combing and the dry combing of examples 1-10 are greater than the combing force reductions for the wet combing and the dry combing performance of comparative examples 1-4. The shampoos of examples 1 to 10 had the effect of preventing hair loss, in terms of higher combing force reduction, indicating better combing property, lower force required, i.e., easier manageability, and less mechanical hair breakage, indicating that hair roots are tough.

It can be seen from the comparison of the control variables with examples 7 and comparative examples 1 to 3 and table 6 that the combing force reduction of wet combing and dry combing after shampooing with the shampoo of comparative example 3 is lower than that of example 7, and from one side, it can be seen that the combination of sodium laureth sulfate, cocamide MEA, and cocamide propyl betaine has no irritation to the scalp hair follicle, and a protective layer can be formed on the surface of the scalp by using the combination of plateau plant extract, citric acid, sodium chloride, guar gum hydroxypropyl trimonium chloride, and other components in the anti-alopecia shampoo, so that not only can the microbial nutrition and acid-base balance of the skin biomembrane at the scalp be maintained, but also the hair follicle can be strengthened and the hair root can be maintained, and the hair care and hair shedding prevention effects can be achieved.

It can be seen from the combination of example 7 and comparative example 4 and table 6 that the combing force reduction degree of wet combing and dry combing of example 7 with sodium chloride added is slightly higher than the effect of removing sodium chloride of comparative example 4, and the sodium chloride can adjust the ion concentration by combining the performance of the sodium chloride, and a protective layer can be formed on the surface of the scalp by matching with the components such as citric acid, guar hydroxypropyl trimonium chloride and the like, so that the effects of maintaining the microbial balance and acid-base balance of the skin biofilm on the scalp can be achieved.

The specific embodiments are merely illustrative of the present application and are not restrictive of the present application, and those skilled in the art can make modifications of the embodiments as required without any inventive contribution thereto after reading the present specification, but only protected by the patent laws within the scope of the claims of the present application.
