인삼·산수유·석창포가 손상모발에 미치는 영향

Abstract

Hair cosmetics tend to be diversified and specialized enough to not only perform such simple functions as hair styling and cleaning but also protect the hairs. Today, as hair styles are frequently changed while hairs are more vulnerable to pollution and various life stresses, consumers are more eager to have refined hair styles and healthy hairs. Thus, various researches have been conducted to meet such needs. The purpose of this study was to empirically determine how the damaged hairs would be affected by he hair treatments using such Oriental medicine materials as ginseng, cornus officinalis and sweet flag, and thereupon, discuss the possibility of these hair treatments as functional hair cosmetics. For this purpose, the researcher tested such hair treatments for their effects on damaged hairs. For this study, the researcher randomly sampled 3 women who had neither used any diet therapy nor took medicines. They represented virgin hair, perm hair and perm＋color hair, respectively. Then, the researcher obtained the hair samples from the same points at the same time by cutting out the parts 2～3cm away from the scalp on the back of the head with scissors. The hair samples were cleaned and left to dry over time. Each 300g of the three testpieces or ginseng, cornus officinalis and sweet flag was divided into 150g parts, respectively to be heated for 8 hours. Each part of the testpieces was treated into extract or powder. Then, each extract and power were mixed at the ratio of 2:1 to produce the hair treatments. The hair treatments were kept at -20℃ and taken out for each hair treatment. The hair treatments were applied ten times to each hair sample for 5～10 minutes each time. Then, the researcher comparatively analyzed tension, weight and epidermis of the hair samples before and after treatment. The results of this study can be summed up as follows; First, as a result of comparatively analyzing the effects of ginseng testpiece, it was found that tension, weight and epidermis of the hair samples were all improved. The more damaged the hair samples were, the effects were higher. Second, the cornus officinalis testpiece served to improve the tension and epidermis of all hair samples, but it worsened the status of perm hair sample in terms of weight and epidermis. Considering that the perm hair sample treated with the cornus officinalis testpiece was oily hair, it was estimated that this hair treatment would react adversely to the oily hairs, but such an estimation should be tested further. Third, the sweet flag hair treatment was found to improve weigh and epidermis of all hair samples, but it was found to lower the tension of the virgin hair sample. All in all, this study proved that such Oriental medicine materials as ginseng, cornus officinalis and sweet flag had the effects of regenerating the damaged hairs. The effects of ginseng were outstanding in every respect, but cornus officinalis had an adverse effect on the perm hair in terms of weight and epidermis. Comus officinalis served to improve tension, weight and epidermis of perm hair and perm＋color hairs but it had an adverse effect on tension of the virgin hair. Such findings suggest that three variables or tension, weight and epidermis may not be correlated with each other after the hair treatment, but such suggestions should be tested further with more precise data. This study is significant in that it has determined the effects of ginseng, cornus officinalis and sweet flag on the damaged hairs. However, this study may be limited in that the hairs were sampled from the scalp and that they were not sampled from the same subject. Hence, it is hoped that this study will be followed up by future longitudinal studies which will test the effects of those Oriental medicine materials on virgin, perm and perm＋color hairs sampled from the same subject and thereby, compare the results with this study.
