| Abstract |
|
The hair color maximizes the image of an individual by emphasizing the characteristics and personality of the individual. But the chemical treatment such as perm and dyeing damages the hair. In this study, keratin and collagen were pretreated before dyeing hair to reduce the hair damage when applying the chemical treatment applying the hair clinic as a post-treatment after dyeing, the hair was dyed from once to three times; and in order to check out the residual amount for the pre- and post-treatments, after conducing 30 Shampoos, the hair thickness, amino acid, and cuticles in the groups of pre- and post-treatments were histologically analyzed. In case of the pretreatment group, due to the addition of protein, the hair thickness became thicker and the total amount of amino acids increased. However, as the damage progressed through the repetitive dyeing, the difference became larger and the elution quality of the total amount of amino acid became eluted about 10 times more; and the difference in the number of the cuticle layer from the post-treatment group was identified. In the post-treatment group, the hair thickness and total amount of amino acids did not increase. However, as the damage progressed repeatedly, the total amount of amino acids in the pre-treatment group were eluted about 10 times less than that in the post-treatment. Therefore, pre- treatment helps to recover the inside of the hair, and post - treatment helps to prevent internal damage. |
