Description

[Technical Field]

[0001] The present invention relates to a fiber treatment composition. [Background technology]

Hair styling using heat from hair irons, hair dryers, etc. can cause hair to dry out, especially at the ends. Damage to hair is becoming more serious. Hair damage causes the hair surface to become hydrophilic and friction to increase. As a result, problems such as tangled ends and difficulty running your fingers through your hair when styling occur. As a result of the formation of cavities inside the hair, light is diffused, making the hair appear whitish and unhealthy. This causes the problem that

The measurement was performed with the surface straight. The measured L value was used to compare the The larger the negative difference (ΔL) in the L value after treatment, the greater the darkening effect, and ΔL of 2.5 or more is considered to be "5: Very high", ΔL less than 2.5 and 1.5 or more is "4: High", ΔL less than 1.5 and 1.0 or more is " 3: Normal, ΔL less than 1.0 and 0.5 or more is "2: Low", ΔL less than 0.5 is "1: Very Low" " and rated on a 5-point scale.

Wet the tresses with water and towel-dried them, then apply each of the solutions shown in Table 1 or 2 at a bath ratio of 0.01 to the hair. 3 and then dried completely using a hairdryer without rinsing. The hair was washed once with shampoo and then completely dried using a hair dryer. Sensory evaluation was performed on the tresses before and after shampooing and when they were dried, and the difference in texture was compared. If the feel remains the same even after shampooing and there is no tangling from the middle to the ends of the hair, then it is rated as "A". Those that felt a slight grip were rated "B", and those that felt a grip were rated "C".
