백하수오와 동물성 밀크를 혼합하여 유산균인 Lactobacillus rhamnosus와 함께 1일 동안 배양 한 결과 pH 및 유산균 개체수에 있어서 이상적인 발효에 도달한 것을 알 수 있었다. 이러한 발효물을 생후 6주령 된 C57BL/6 마우스에 1일 1회, 8일 동안 붓을 사용하여 매 회 100 ${\mu}L$씩 경피 도포하여 모발성장 촉진효과를 관찰한 실험에서 다음과 같은 결과를 얻었다. 실험기간 동안 모든 군에서 체중과 사료 섭취량이 큰 차이를 나타내지 않았으며, 육안적 관찰에서 무처리군과 음성대조군에서 모발성장이 약하게 관찰되었고, 양성대조군인 미녹시딜 처리군에서는 평균 62%의 모발성장이 관찰되었으며, 실험군인 백하수오 유산균 발효군에서는 평균 90% 이상의 정상적인 모발성장이 관찰되었다. 피부조직의 H&E 염색 후 분석 결과 8일째 희생한 마우스의 무처리군과 음성 대조군에서 모낭의 수 및 크기가 작고 모근의 길이가 작았고, 양성대조군에서는 모낭의 수, 크기 및 모근의 길이가 무처리군과 음성대조군에 비해 약간 신장한 것을 알 수 있었으며, 백하수오 유산균 발효군인 실험군에서는 모낭의 수, 크기 및 모근의 길이가 다른 군에 비해 크게 관찰되었다. 이상의 실험결과를 통해 백하수오와 동물성 밀크를 유산균인 Lactobacillus rhamnosus와 같이 발효하여 얻은 발효액은 우수한 모발성장 촉진효과를 보였으며, 미녹시딜보다 더 높은 효과를 나타냄을 알 수 있었다.

아름다움을 추구하려는 외모의 중대성이 부각됨에 따라 모발 염색을 포함한 미용 산업의 시장규모도 점점 커지고 있다. 헤어살롱에서 보편적으로 사용되는 산화염모제를 지속적으로 시술할 경우 모발 손상은 피할 수 없게 되므로 중명도 산화염모제를 시술한 모발의 형태학적 변화에 관하여 연구하였다. 실험결과 control과 6N-7N 실험군 간에 Max. load, Max. stress, Max. elongation, Break load, Break stress, Break elongation, strain 구간에 따른 Max. modulus 및 Tangential modulus는 유의적인 차이를 보였다. Max. load, Max. stress, Max. elongation, Break load, Break stress 및 Break elongation은 모두 대조군이 가장 높은 값으로 나타났으며, 실험군의 처리에 따른 유의적으로 감소하는 경향은 보이지 않았다. strain 평가구간에 따른 Max. modulus와 Tangential modulus는 대조군과 실험군 간에 차이가 있음에도 일정하게 증가하거나 감소하는 경향이 뚜렷하게 나타나지 않았다. 본 연구를 통해 모발손상을 최소화하는 산화염모제 개발 연구의 기초자료 제공 및 헤어디자이너들의 산화염모제와 모발 건강과의 상관관계 이해를 위한 초석을 다지고자 한다.

미적(美的) 욕구표현의 수단으로 현대인은 외모 치장에 많은 시간과 경제적 투자를 하고 있으며, 외모의 대부분을 차지하는 헤어미용 중 멋 내기 모발 염색을 많이 애용하지만 이에 따른 모발손상도 심각한 상태이다. 그러므로 모발손상을 최소화하면서 멋 내기를 유도할 수 있도록 산화염모제에 따른 모발 인장강도에 관한 연구를 하고자 한다. 연구결과 대조군과 8N-10N 실험군 간 최대하중, 최대 인장강도, 최대 신장률, 파단 하중, 파단 강도, 파단 신장률, 평가구간에 따른 최대 모듈러스 및 접선 계수 등은 서로 유의적인 차이를 보였다. Strain 구간에 따른 최대 모듈러스와 접선 계수인 tangential modulus는 대조군과 실험군 간 차이가 있음에도 일정하게 증가하거나 감소하는 경향이 뚜렷하게 나타나지 않았다. 따라서 본 연구는 산업체 현장에서 애용되고 있는 고명도(高明渡) 멋 내기 산화염모제 시술을 통한 모발손상과의 상관관계를 데이터로 규명함으로써 헤어미용 교육 자료로서의 활용 및 헤어디자이너의 올바른 산화염모제 선택을 위한 응용자료를 제공하고자 한다.

In the study of permanent waving method after mixing ample and permanent wave solvent in permanent wave the dyed humans hair are as follows; First, Permanent waving method after mixing ample and permanent wave solvent is that the better effective way in permanent wave the dyed humans hair because permanent waving cycle is constant and hair cuticle is glossy. Second, This study is not interpret in permanent wave dyed humans hair that tensile strength is effect of permanent waving method after mixing ample and permanent wave solvent. A extension degree is effect of permanent waving method after mixing ample and permanent wave solvent use indifferent ample treatment method. Third, Hair cuticle damages are a little permanent waving method after mixing ample and permanent wave solvent in permanent wave dyed humans hair.

The results of study for colorless hair manicure, which is well known for its useful point and supplement damaged hair glossy, luster, elastic and soft one are as follows. Hair protection effect by the management time of colorless hair manicure products, as below. When it comes to dyed hair group's hair surface condition. both level 3 and level 6 hairs cuticle changed to be irregular. And lose of cuticle has been observed with a fact that the space between cuticles are not clear. In case of manicuring, manicuring 2 weeks after dyeing is better complemented surface damage than manicuring right after dyeing. So, in case of making cuticle morphologic of good hair quality in manicuring dyed hair, it's more effective to manicure right after dyeing to both level 3 and level 6 hair.

Generally, hair treatments by complementary actions to give a sense of activity are permanent setting, dyeing, and bleaching, etc. In this study, we investigated the wave formation ability and hair damage occuring in permanent setting and bleaching process. The wave formation ability was evaluated by the differences of length and curl diameter after permanent setting. And the hair damage was also evaluated by the protein release ability and SEM of hair. The bleached hair immediately after permanent setting treatment has better wave formation ability, but much more damaged than the bleached hair after rinsing thoroughly with warm water. It was considered that the chain of hair keratin broke down easily by the bleaching action in the existence of permanent setting agents.

This study reduced the number of hair bleachings and used a hair steamer machine to reduce hair damage during hair coloring. In addition, such treatment was given, focusing on the use of hair mist. When the $L^{\ast}a^{\ast}b^{\ast}$ values for bleached hair were measured using a spectrum colorimeter, the mist steamer-based hair revealed higher brightness. Hair damage was low when moisture contents were high after hair drying with the use of the mist steamer machine. The mist treatment-less hair showed more blurred cuticle boundaries than mist-treated hair. In other words, this confirms that cuticles are protected by the use of a mist steamer machine during hair bleaching. It appears that this could minimize hair loss and meet clients' aesthetic needs and satisfaction during color bleaching/coloring.

Recently, it has been reported that chemical hair coloring can cause allergic reactions, the toxicity issue of chemical hair color was issued. Therefore, there is an increasing interest in the hair coloration technique using non-toxic and bio-compatible hair color gotten from natural resource. In this study, the possibility using fermented Indigo as natural hair coloring agent was investigated. Bleached hair samples were dyed using Indigo, and the effect of dyeing frequency, the physical change after dyeing, color, surface and cross-section characteristics, and tensile property were also studied. In addition, the protection property of cationic detergent finishing on damaged hair samples were also studied. The following conclusions are made; 1. While bleached hair samples with low value showed the negligible effect of repeated dyeing, bleached hair samples with high value showed the good effect of repeated dyeing. 2. Hair sample dyed with Indigo showed a high light-fastness, however, tensile strength and elongation showed very low values (high damage on hair sample). 3. Cationic detergent finishing did not affect on the colorfastness because of decoloration after dyeing, however, it increased the smoothness of hair sample, and therefore, can use as protectant of damaged hair. 4. Hair scale was damaged after dyeing. It seemed that the alkali, potassium carbonate, increased pH of dyeing bath to 11, as a result, the hair was swollen, weaken, and dissolved on the prolonged dyeing time. Dyed hair sample became stiff and fine. 5. The color difference was 4.62 (a high fastness value) in the test of sunlight exposure, shampoo, cationic detergent finishing, and acid perspiration fastness.

This thesis aimed to reduce the differences of hair color when hair coloring, so it researched the differences & changes in hair color before shampoo v.s. after shampoo and dry on different heat processes when acid hair color dyeing. Five hair color dyes (Y, R, B, G, Br) manufactured by two different corporations were used. The acid hair color dyes were tinted on black and bleached hair pieces subjected to 3 different heat process; 1. Normal Temperature($25^{\circ}C$, 30min.) / 2. Heating($40^{\circ}C$, 15min.)+Normal Temperature($25^{\circ}C$, 15min.) / 3. Heating($40^{\circ}C$, 30min.). Color numbers were divided by NCS value, chroma, and hue. Statistical averages were derived and t-test was conducted using SPSS V12. Hair color differences and changes were drawn on an NCS chart using Photo Shop PS. The conclu is; If acid hair colorings are separated by a heating process, hair value & chroma change before shampoo vs. after shampoo & dry regardless of the color of hair and the heat process. Hue is not changed or shifted counter clockwise NCS color circle, but some exceptions, and it's the same when the total heat process results are combined. Black hair's value shifted downward and chroma left, and hue stayed either neutral or one color or it shifted counter clockwise on NCS color circle. Bleached hair's value shifted upward and chroma right, and hue stayed one color or shifted counter clockwise, but some exceptions. And it can be shown on NCS chart.

In this work, the effects of surfactant and solvents, such as benzyl alcohol and n-propyl alcohol, on the human hair dyeing with acid dye was investigated including the amount of dyes in hair according to dyeing time, temperature, and pH. And the damage of dyed hair was assessed by water retention, protein release, and SEM images of the dyed hairs. By adding benzyl alcohol in acid dyeing, the dyeing rate was increased and the dyeing equilibrium was established at early stage. The water retention of the dyed hair was increased and the protein release of the dyed hair was decreased. Therefore the hair was damaged less during the dyeing.
