This study is to examine the relation between self-consciousness and appearance management behavior; to grasp the appearance management behavior depending on self-consciousness which older women feel personally; to understand their needs more deeply; and to give support in planning and conducting marketing strategies effectively in the beauty and fashion market. The subjects of this study were aged women ranging 55 to 69 in age, living in Daegu and Geongsangbukdo. 500 questionnaires were distributed and 397 questionnaires out of 440 returned were used in the data analysis. The results through statistic analyses are following: 1. Among older women, the higher social self-consciousness group appeared to pursue six types of appearance management behavior(i.e., weight body-shape care, skin care, cosmetic behavior, hair care, cosmetic surgery, and clothing behavior) much more than the lower social self-consciousness group. 2. Compared with the lower private self-consciousness group, the higher private self-consciousness group appeared to care for not only weight body-shape care but also skin care, cosmetic care, and cosmetic surgery, clothing behavior with more interest in ordinary times. In terms of hair care, though, there was no significant difference between the higher private self-consciousness group and the lower private self-consciousness group. 3. There was no statistically significant difference between the higher social anxiety group and the lower social anxiety group in weight body-shape care, skin care, cosmetic behavior, hair care, cosmetic surgery, and clothing behavior.

Hair, having distinct stages of growth, is a dynamic component of the integumentary system. Nonetheless, derangement in its structure and growth pattern often provides vital clues for the diagnosis of systemic diseases. Assessment of the hair structure by various microscopy techniques is, hence, a valuable tool for the diagnosis of several systemic and cutaneous disorders. Systemic illnesses like Comel-Netherton syndrome, Griscelli syndrome, Chediak Higashi syndrome, and Menkes disease display pathognomonic findings on hair microscopy which, consequently, provide crucial evidence for disease diagnosis. With minimal training, light microscopy of the hair can easily be performed even by clinicians and other health care providers which can, thus, serve as a useful tool for disease diagnosis at the patient's bedside. This is especially true for resource-constrained settings where access and availability of advanced investigations (like molecular diagnostics) is a major constraint. Despite its immense clinical utility and non-invasive nature, hair microscopy seems to be an underutilized diagnostic modality. Lack of awareness regarding the important findings on hair microscopy may be one of the crucial reasons for its underutilization. Herein, we, therefore, present a comprehensive overview of the available methods for hair microscopy and the pertinent findings that can be observed in various diseases.

모발표면에는 독특한 형태의 지방산이 있다. 18-methyleicosanoic acid (18-MEA)는 모발 큐티클의 최외각 층에 공유결합된 특이한 ante-iso 형태의 지방산이다. 18-MEA 층은 CMC의 ${\beta}$-층 위에 위치하면서 모발의 외부 표면에 표면에너지와 마찰저항 을 낮춰준다. 18-MEA 분자의 높은 유동성은 계면 전단력을 감소시켜 외부로부터 전달되는 지질들이 쉽게 퍼지도록 한다. 본 연구에서는 C10 - 40 isoalkyl acid의 말단에 관능기로 N-hydroxyl succinimidyl ester를 도입하여 모발 표면의 공유결합 지방산 층을 회복시켜보고 자 하였다. 모발 표면의 재 소수화를 확인하기 위하여 접촉각을 측정하였다. 서로 다른 습도 조건(40, 55, 70 %RH)에서 모발의 내부 수 분 함유량은 전자 수분 분석기를 이용하여 실시하였다. Hydroxysuccinimidyl C10 - 40 Isoalkyl Acidate (HCIA)로 처리한 모발의 표면은 큐티클을 접착하는 것과 같이 지방산 단분자층이 공유결합을 형성하여 큐티클의 균열을 채워줌으로써 매끄럽고 균일할 것으로 생각되었다. 이러한 접착 효과는 atomic force microscope (AFM) 영상의 라인 프로필(line profile)을 통해서 확인되었다. 따라서 모발 내부 구 성 물질과 수분이 쉽게 용출되지 않고, 외기의 습도가 변하는 경우에도 최적의 모발 습도가 항상 유지된다. AFM을 사용한 lateral force microscopy (LFM) 결과에 따르면 HCIA를 처리한 모발 표면의 마찰력이 감소되었고, 이에 대해 15회 샴푸 과정을 수행한 이후에도 동일한 마찰력 값을 나타내었다.

This study attempted to determine the effects of fermented green tea extracts on hair by using them in a perm. For this, hair is bleached, and then the fermented green tea extracts and water were supplied to the hair using a mist sprayer. Then the hair was permed, and hair damage was tested. Regarding hair moisture levels and wave formation, specifically, the morphological changes of hair were investigated with the Scanning Electron Microscope(SEM). The study results found the following. In terms of wave formation, the fermented green tea extract-based perm was much better than the general perm. In addition, hair bleaching was more serious in the latter. According to analysis on hair moisture using SEM, hair damage was more prevalent in the general perm as well. Therefore, it was confirmed that green tea extract-based perms cause less damage to the cuticle. In other words, the potential of fermented green tea extracts as a hair cosmetics material was discovered. Furthermore, it appears that the study results contribute to the development of low-irritating scalp and hair care products using the anti-inflammatory and antimicrobial properties of the fermented green tea extracts.

Caffeine is widely used in cosmetics and hair care products. Although its efficacy in stimulating hair growth has been confirmed in recent studies, its mechanism of action remains unelucidated. The present study aimed to determine the effects of caffeine on hair growth, with a focus on intracellular hair follicle activity. Experiments included in vitro and ex vivo tests, and a clinical study. Caffeine enhanced the cellular activity and potassium channel opening. It also promoted human hair follicle elongation. Immunohistochemical staining showed that the Ki-67 signal was significantly higher in cells treated with caffeine. These efficacies of caffeine were comprehensively demonstrated in clinical results, wherein caffeine-containing shampoo improved hair density after 24 weeks of testing. Collectively, the results of this study demonstrated that caffeine promoted hair growth and inhibited the progression of hair loss by enhancing intracellular activity of hair follicles.

The purpose of this study was to explore how the Theory of Planned Behavior applies to five appearance management behaviors and the effects of three variables - attitude, subjective norm, and perceived behavior control on appearance management behaviors. The research was conducted by surveying 410 female adult respondents between the ages of 20 to 40 with the goal of predicting the appearance management behavior of women. The data were analyzed using IBM SPSS Statistics 19.0 and Amos 19 in addition to Frequency analysis and path analysis. In the first case, the potential for applying appearance management theory on appearance management behavior of women was observed. The appearance management behavior performed by women was classified into five categories: skin care behavior, makeup management behavior, apparel management behavior, hair care behavior, and weight management behavior. It was determined all five behaviors could be predicted by applying the Theory of Planned Behavior. In the second case, effects of attitude related to subjective norm and perceived behavior control related to skin care behavior was statistically significant. In terms of makeup management behavior, all of the three variables were statistically significant. With regard to apparel management behavior, only subjective norm behavior was statistically significant. Concerning hair care behavior, attitude and perceived behavior control were statistically significant. On weight management behavior only attitude was statistically significant.
