A Study of Changes in Degree of Hair Damage and Hair Color after Use of Taraxaci Herba Shampoo at Hair Dyeing

This study aimed to produce a shampoo with using extract of Taraxacum Herba and to develop hair care products. For this, changes in the degree of hair damage and hair color were observed by washing dyed hair with an oxidized hair dye to verify the efficacy of the Taraxacum Herba shampoo. For accurate verification, a comparative analysis was conducted using various shampoos on the market. After dyeing test hair with the oxidized hair dye, they were washed with each shampoo. The shampoos manufactured by ‘A’ were divided into regular shampoo, color care shampoo, conditioning shampoo and Taraxacum Herba shampoo and comparatively analyzed. In terms of tensile strength, the hair washed with the Taraxacum Herba shampoo was the greatest, followed by the conditioning shampoo, color care shampoo and regular shampoo. According to the analysis of hair components, in terms of sulfur contents, hair washed with the Taraxacum Herba shampoo was the highest, followed by the conditioning shampoo, color care shampoo and regular shampoo. In terms of hair damage measured using the MB dye method, hair washed with the Taraxacum Herba shampoo was the weakest, followed by the conditioning shampoo, color care shampoo and regular shampoo. In terms of the degree of hair color in which L* values were comparatively analyzed, hair washed with the regular shampoo was the brightest, followed by the conditioning shampoo. The color care shampoo and Taraxacum Herba shampoo were less bright, relatively. The said results found that when the Taraxacum Herba shampoo was used after hair dyeing, hair damage and loss of hair color were minimized. Therefore, it was shown that the Taraxacum Herba shampoo has a positive effect on dyeing properties as well.
