  • 모발(human hair)은 양모섬유와 마찬가지로 시스틴을 많이 함유하고 있는 섬유상 케라틴 단백질로써, 두부(頭部)를 보호할 뿐만아니라 신체에 필요하지 않는 중금속을 체외로 방출하는 기능을 지닌 신체의 일부분이다. 또한 모발은 미(美)와 관련하여 가장 관심을 가지는 부분이며, 다양한 방법으로 모발에 변화를 주어 신분을 표시하거나 자신의 미적 표현을 하고 있다. 퍼머넌트 웨이브는 모발에 형태학적 변화를 주는 유효한 수단이며, 염색과 탈색 등은 색상 변화를 주는 중요한 수단이다. 본 연구 에서는 모발을 산성염료로 염색할 때 염색성을 향상시키기 위하여 염색보조제로써 벤질알콜 등을 첨가하여 염색할 때 염색된 모발의 염착량, 보습성, 단백질 유출성, 주사전자 현미경 관찰을 측정하여 다음과 같은 결과를 얻었다. 1) 염색시간이 길어지고, 염색온도가 높아질수록 모발에의 염착량은 증가하며, 특히 벤질 알콜을 첨가하여 염색하는 경우에는 빠른 시간내에 염착평형에 도달하고 비교적 낮은 염색온도에서도 높은 염착량을 나타내었다. 2) 이와같은 용매 첨가의 효과는 염액에 계면활성제와 함께 첨가하여 염색하면 나타나지 않았다. 3) 염색시간이 길어질수록 모발의 보습성은 열악해지지만, 벤질 알콜을 첨가하여 염색하는 경우에는 오히려 보습성이 증가하였다. 또한 염색시간이 길어지면 모발의 단백질 유출성은 증가하지만, 벤질 알콜을 첨가하여 염색하는 경우에는 오히려 단백질 유출성이 감소하였다. 이와같은 결과는 벤질 알콜을 첨가하여 염색하는 경우에 모발의 손상이 적다는 것을 의미한다. 4) 모발의 손상정도에 대한 주사전자현미경의 측정결과는 벤질 알콜의 첨가여부에 따라 큰 차이를 보이지 않았다.

  • The purpose of this study is to investigate the efficacy of juglone, which shows hish affinity to wool, for hair dyeing as a natural dye. Before dyeing hair with juglone, virgin hair was bleached by a conventional method using hair shops in the city. In order to study the dyeing properties of juglone on hair, the effects of dyeing conditions on dye uptake, color, tensile strength, and morphology were investigated. And the effect of Fe-mordanting on color change was also investigated. Dye uptake changed marginally as dye concentration increased in the range of 0.02-0.04g. Dye uptake increased progressively is dyeing time increased in the range of 10-20 min. Juglone produced YR colors on hair and the color of dyed hair got duller as juglone concentration increased. The hair was little damaged by bleaching, but cuticles were melted and stripped away by dyeing for longer time. Tensile strength retention decreased up to 65% at 20 min dyeing. Simultaneous mordanting with Fe did not improved dye uptake, but led to darker brown color compared with unmordanted hair.

  • In this research, I chose and studied colorless hair manicure, which is well known for its useful point and supplement damaged hair glossy, luster, elastic and soft one. Also I studied and found hair protection effect by the management time of colorless hair manicure products, as below. Both level 3 and level 6 hairs, when they get damaged after dyeing, both hairs' strength and enlargement are affected. Manicuring two weeks after dyeing is more effective way than manicuring right after dyeing. So, in case of making good hair quality in manicuring dyed hair, it's more effective to manicure right after dyeing to both level 3 and level 6 hair. To complement hair's damage, however, manicuring two weeks after dyeing is the best effective way.

  • Recently. dyeing by harmless natural materials has received much attention due to the side-effects occurred from dyeing by synthetic dyes. In this study, we examined the effect of extracts of Pueraria thunbergiana (P. thunbergiana) roots, which are treated as natural products as well as agricultural wastes, on the hair dyeing by measuring dyeing interval, temperature, density changes, mordant and chromatic faction. The hair dyeing by the extracts significantly reduced hair damage and kept cuticle of hair softer than that by synthetic dyes. In addition, since a mordant is one of the necessary additives in dyeing, the role of a mordant was studied and concluded to be a supplementary substance based on the results that the hair dyeing by the extracts of P. thunbergiana roots alone was much darker than the others. Taken together, the data presented in this study suggest that the extracts of P. thunbergiana roots are is less damageable to hair and thus can be more safely applicable to hair dyes than that by synthetic dyes.

  • Morphological and physicochemical changes of a woman's virgin hair treated with various dye depths were investigated by using scanning electron microscopy and thermal analyzer. With the hair treated with the dye of the high brightness level, the speed of weight decrease was slower than compared with thermal analysis weight of a normal hair sample. We confirmed that the moisture content and protein composition of hair were changed depending on level depth of coloring agent. Moreover oxidative residues and dye molecules penetrated into the hair cause chemical changes of hair structure. As a result, the heat reaction speed of hair treated with high level coloring agent was made slower than normal hair.

  • Hair beauty treatments that can express individuality have increased and diversified. However, their repetitive use has also brought about hair damage. To reduce such damage, the importance of hair treatments when receiving chemotherapy has magnified greatly. In this study, the hair (normal hair, NH) of 5 people in their 20s has been collected and observed with SEM before dyeing (NH), after dyeing (DH) and after dyed and treated (DTH) to measure the hair's morphological damage and mineral content. SEM observation results revealed that, in DTH, a cuticle-like arrangement appears almost uniformly, the hair settles, the lines are smooth, and the damage degree is low. Regarding mineral content, the concentration of minerals was generally balanced. However, in the observation of toxic minerals and minerals found in large amounts, the concentration of Ba, Na, Ca, and Mg was higher than the balance range in NH, DH, and DTH.

  • Stained and discolored hair will be damaged by the shampooing, daily UV disposal, and the use of hair dryer. Thus many studies about the effect of various natural substances on the re-secure the skin and scalp are recently reported. This study was carried out to investigate the effect of green tea (Camelloia sinensis) seed oil on colored (dyed) and decolored (bleached) hair. The beneficial effects of green tea seed oil are already well known, but little research has been done about the hair treatment and fade-resistant effect. Dyed and bleached hair was pretreated with green tea seed oil to determine the tensile strength and elongation of the hair, to analyze the hair surface using SEM, and to compare the color fade using spectrocolormeter. The results showed that the tensile strength increased with green tea seed oil pretreatment samples for virgin, dyed, and bleached hairs. Elongation showed the reverse results showing the presence of hair treatment effect. The results of the surface pre-treatment in all groups analyzed by SEM, the hair cuticle became sharper, so coating effect were identified with all samples. The value of the $L^*$, $a^*$, $b^*$ decreased with washed hairs damaged by UV irradiation and the values were decreased also in dyed and bleached hair. In summary, green tea seed oil prevent reinjury to the heat and UV rays for colored and decolored hairs. Cosmetic practice effects of the oil were identified in the field to be appropriate to the customer's skin and scalp that natural cosmetic oils would like to offer.

  • In this study, we compared the stress and tensile strength of the hair treated with oxidative permanent dye with those of virgin hair. We investigated the fine structure of the hair section after the tensile test using scanning electron microscopy. The tensile strength of the virgin hair was measured as $14.66\;g/cm^2$, tensile energy was $108\;erg/cm^2$, and the maximum stress was 146.64g. Those of the dyed hair were $13.69\;g/cm^2$, $89.62\;erg/cm^2$ and 136.90 g, respectively. The differences in the tensile strength, the tensile energy and the maximum stress were $-0.97\;g/cm^2$, $-18.38\;erg/cm^2$, -9.74 g, respectively, which showed that the dyed hair had less elasticity and strength than the virgin hair. In the scanning electron microscopy investigation of the damaged hair after the tensile test, lift-off of the cuticle outer layer were shown in both virgin hair and dyed hair, which was more severe in the dyed hair than the virgin hair. Adjacent cuticular cells of the cuticle layer were separated by the destruction of intercellular membrane complex. The macrofibrils were exposed and separated from the cortex torn by tensile strength.

  • Onions are commonly available and easily processed, and since their skins are thrown away they could be very useful materials from the viewpoint of environmental preservation. This study aimed to process onion skins into the state of powder and look into the optimum condition for hair dyeing by decoloring virgin hair four times and observing the hair dyeing quality and its mechanical and morphologic changes by the different condition of onion skins in duration, temperature, density, pH, and mordant treatment. The observations of hair surface through scanning microscopy showed the formation of cuticle layer, though in a little blown-up state in the case of the hair dyed with onion skin application, when compared with bleaching hair with the completely dissolved cuticle layer. According to the above findings of experiments, the dyeing quality of the hair dyes with onion skin application was excellent, the dyeing was also feasible without mordants, and the use of Fe as the mordant increased dyeing exhaustion more, which would make it an effective hair dye. These results of the experiments indicate that the natural pigment extracted from onion skins can be actually used for hair dyeing from the viewpoints of the dyeing quality and the skin treatment.

  • The goal of this study was to get the basic data for the domestic cosmetic industry, through analyzing female college ,students’ responses to cosmetic care of hair and their behavior, and their preference for hair cosmetics and brands. In their level of understanding and concern of hair cosmetic care, as well as their general knowledge, ‘dyed or decolorized hair’ types had the highest response rate at 49%, followed by ‘permanent wave’ type at 39%. Thus they were very interested in hairdressing-related operations, and even they made an attempt to do it directly. In the ways and management for dealing with harmful side effects caused by dyeing, decolorizing, or permanent, 74.7% of the respondents experienced adverse effects, as well as having complaints, after permanent wave. Of the complaints 245 students experienced, ‘hair damage’ was the highest rate of 42.4%, followed by ‘unsatisfied with hair style’ at 19.8%. From the above results, female college students showed a various interest in hair cosmetic care; however, they had little knowledge in this regard. Accordingly, it is necessary to educate them for the segmentation of hair cosmetics and the appropriate hair care, to meet their diversified cosmetic needs which becomes diversified, and to offer them the correct information of hair beauty.
