Description

Technical Field

[0001] The invention belongs to the technical field of daily chemical products, and particularly relates to a composition for hair care with the effect of repairing damaged hair and a preparation method thereof. Background Art

[0002] Damage to hair quality is mainly related to structural damage to the hair. Hair is mainly composed of three parts: cuticle, cortex and medulla. Cuticle is the outermost layer of hair. Healthy cuticle is complete and docile, so the surface of hair is very soft and shiny. If the cuticle is curled, damaged or even missing, the rough surface will slowly reflect the light, and the hair will naturally become dry and frizzy. The cortex is the largest part of the hair, which controls the moisture of the hair and gives the hair toughness and strength. The medulla is located in the center of the cortex, affecting the color depth of the hair and is easily changed by dyes. The cuticle, which is rich in hard keratin, covers the entire hair fiber and forms a scale-like structure on the surface. Although it is very thin, it plays an important protective role. The cuticle cells determine the glossiness of the hair. Damage to the cuticle will directly lead to a decrease in the smoothness of the hair, and the moisture of the hair will be lost faster, causing the hair to dry. Since the cuticle wraps the cortex and medulla together, once damaged, it will gradually lead to split ends of the hair.

[0003] Damaged hair can be divided into four categories: mildly damaged hair, moderately damaged hair, severely damaged hair, and extremely damaged hair. Mildly damaged hair is mainly due to the damage of the hydrophobic protective layer, which causes the hair to lose moisture and become dull and matte. Moderately damaged hair is due to the damage and shedding of the hair scales, holes in the hair cuticle, and lack of nutrition for the hair. Without effective care for a long time, the hair will further dry out and even break. There are two ways that hair is damaged: physical damage and chemical damage. Physical damage mainly comes from combing and wear, while chemical damage includes chemical treatments such as dyeing and perming. Ultraviolet rays can also damage hair and cause damage to the hair scales.

[0004] The importance of repairing damaged hair is that once damaged, hair cannot repair itself. Damaged hair not only looks bad, but is also prone to further damage, and can even lead to hair loss and graying. Proper care, such as maintaining a healthy lifestyle, using repairing hair care products, and regularly trimming the ends of your hair, can effectively improve hair quality and restore its health and beauty.

[0005] Therefore, providing a product that can repair damaged hair is the key to hair care. Summary of the invention

[0079] Test Example 2: Moisturizing Effect Verification

[0080] The damaged hair samples were prepared by the method of Test Example 1. The damaged hair repairing compositions prepared in Examples 1-3 and Comparative Examples 1-4 were prepared into 10% (m / v) solutions with deionized water, and equal amounts of damaged hair samples were immersed in the above solutions, treated at 35±2°C for 60 minutes, and washed with deionized water several times after the treatment until no residue was left in the solution, and dried to constant weight.

[0081] At room temperature, each group of hair samples were placed in an environment with a relative humidity of 90% for 24 hours, and the weight was recorded as Mw. Then they were quickly transferred to an environment with a relative humidity of 20% and placed for another 24 hours, and the weight was recorded as Md. The water loss rate was calculated according to the formula (Mw-Md) / Mw*100% to evaluate the moisturizing performance of the hair samples, and the average value was taken. The results are shown in Table 4.

[0083]

[0084]

[0085] Compared with Example 2, the average water loss rate of the hair samples of Comparative Examples 1-4 is significantly increased, and the data has significant differences. The test results show that the composition for hair care with the effect of repairing damaged hair of the present invention significantly reduces the water loss rate of perm-damaged hair samples and improves the moisturizing ability of perm-damaged hair samples. The improvement of moisturizing ability helps to reduce the occurrence of dry and rough hair and improve the smoothness and combability of hair.

[0086] Test Example 3 Sensory Evaluation

[0087] 35 healthy female volunteers with long hair, whose hair is dry, frizzy and easy to break due to frequent dyeing, perming and bleaching, were recruited. The volunteers were aged between 25 and 35 years old and randomly divided into 5 groups, each with 7 cases. The hair care essential oils prepared from the compositions for hair care with the effect of repairing damaged hair of Example 2 and Comparative Examples 1-4 were used respectively. The amount of the composition added in the hair care essential oils was 8% (m / v). After each shampooing, the hair care essential oils were evenly applied to the hair, and gently massaged until completely absorbed. The hair care essential oils were used 2 to 3 times a week for 8 consecutive weeks. During the use period, the hair dyeing, perming and bleaching were stopped. After 8 weeks, a scoring system of 1 to 10 points was used, with 1 point indicating complete ineffectiveness and 10 points indicating obvious improvement. The average value was statistically calculated and the results were recorded in Table 5.
