헤어(Hair)의 연출은 현대인의 개성 창출을 위한 요소로 작용하고 있으나 염색(Dye), 펌(Prem) 등과 같은 반복적인 화학 시술은 모발 손상을 초래하게 된다. 손상을 줄이기 위한 화학 시술 방법으로 헤어 트리트먼트(hair treatment)에 대한 중요성이 크게 부각되고 있다. 따라서 본 연구에서는 염색 시, 헤어 트리트먼트의 사용이 실제 모발의 형태학적 손상도와 모발 내의 유독성 미네랄과 필수 미네랄의 수치에 어떠한 영향을 미치는지를 확인하기 위해, 20대 전 후반 5명의 모발(normal hair, NH)을 채취하여 염색 전 모발(NH), 염색 모발(dye hair, DH), 염색제와 헤어 트리트먼트 혼합 모발(dye with treatment hair, DTH)의 형태학적 손상도를 관찰하였으며, 모발 속 중금속 및 미네랄(mineral) 함량분석을 통하여 염모제와 헤어 트리트먼트에 의한 모발 내 중금속 변화를 조사하였다. 모발의 형태학적 영향은 DTH 모발에서 DH나 NH에 비하여 큐티클 형태의 배열이 대체적으로 균일하게 보여 지며, 들뜸이 차분해지고 선이 매끄럽게 관찰 되어 손상도가 적게 관찰되었다. 미네랄 함량의 농도 부분에서는 대체적으로 균형범위에 있었으나 유독성 미네랄 부분에서는 바륨(Ba), 영양미네랄 부분에서는 Na, Ca, Mg의 농도가 NH모발, DH모발, DTH모발에서 균형범위보다 높게 나타났다.

In this study, we investigated the morphological and physical changes of hair after bleaching treatments with different concentration of hydrogen peroxide in bleaching agent (3, 6, 9, or 12%) and various treatment time (10, 30, or 60 minutes). Tresses of virgin black hair were bleached using a commercial ammonium persulfate-hydrogen peroxide solution. The tensile strength of virgin hair treated with a bleaching agent depended on the concentration of hydrogen peroxide and the treatment time. As the concentration of hydrogen peroxide in bleaching agent went high and the treatment time increased, the tensile strength of the hair increased but the extension degree decreased. The virgin hairs which were not treated by bleaching agent showed morphologically healthy cuticle, whereas the bleached hairs showed swelled and damaged cuticle patterns. The swelling of the hair and the breaks of the cuticles increased positively by the concentration of hydrogen peroxide and the treatment time. These results suggest that exposure to more concentrated hydrogen peroxide with other bleaching components may lead to more severe hair damage.

As you see, there's no difference of the hair's before and after Magic straight permanent on the example A's hair's thickness, the rate of the tense and the C's rate of the tense, but we can find that there are a lot of difference of the A's strength of the hair, the B's hair's thickness, the strength of the hair, the rate of the tense, the C's hair's thickness, and the strength of the hair on the before and after the Magic straight permanent. That is to say, there are more damage on the condition of normal hair than the one after the Magic straight permanent. On the change of the hair's physical character, before the permanent, the hair's schedule was regular and had the healthy head skin of clear mutual boundary But after the Magic straight permanent wave, the hair's schedule changed to unregural, had unclear mutual boundary of the head skin and the schedule was taken off so the cortex showed up and so on, every condition of the damage was very heavy. On the effect of the treatment, even though it gaves the worth condition of the hair, after the Magic straight permanent formally the change of the hair gives the beautiful straight.

In this study, "housewives" are defined as married women who take care of housework mostly and do not work outside of home. Changing family types and higher education level of housewives enable them to be more interested in heath, beauty, and appearance. Increased interest and more frequent visits to hair salons cause scalp damage as well as hair damage, which results in hair loss. Moreover, some women suffers from scalp and hair damage due to childbirth, but many of them are not aware of it. Therefore, this study tries to find out the following; housewives' perceptions on hair and scalp management, and how such perceptions are formed. In addition, this study will present the direction for beauty marketing taking into account the characteristics of housewives and provide data necessary for them to keep their hair and scalp healthy. For these purposes, a survey was carried out after modifying the questionnaire through a presurvey. The survey tried to find 1) perceptions on hair and scalp management according to demographic characteristics, and attitude toward hair and scalp management according to demographic characteristics. Data were analyzed using frequency analysis, cross tabulation, t-test, factor analysis, and Analysis of Variance. The results were as follows, most recognize the importance of hair and scalp management but do not receive management because of the high cost, most of them receive information about hair and scalp management from people around them, and the higher the education level and health status, the more active the attitude toward hair and scalp management. These differences were all statistically significant.

This research is the hair damage as treating a perm before and after that is compared the change of surface characteristics of human hair. On the basis of this, we would to show a basic data for hair damage prevention and hair improvement to keep the beautiful and healthy hair. Results are as follows; For the change of formational characteristics of hair surface, untreated hair before the perm treatment had smooth appearance overall and undamaged scale that is in pattern and finely folded was observed but damaged hair and extremely hair had uneven edge and damages throughout along with the dissolution of scale which the border of epidermal gap is unclear. Hair after a perm treatment caused cortical exposures due to extensive loss of scale during the treatment and even bubble effect. Protein perm, regular perm, soft perm, and direct heating perm, in that order, had the most damages to the hair.

The inner hair cell stereocilia of the guinea pig cochlea was examined under a scanning electron microscope (SEM) after loud tone exposure onto the ear drum of the animal. Before and after guinea pigs were exposed to intensive and continuous tone such as 106 dB SPL in intensity, the functioning of the cochlea was monitored by N1-N2 audiograms. The structural damage of the stereocilia of inner hair cells (IHCs) and outer hair cells (OHCs) was examined using the SEM in x 1500 magnification. The comparison between the functional change of the cochlea and the structural damage of the IHC stereocilia is done by means of photographic observation. It can be shown that the functional change might be related to the structural damage of the IHC stereocilia after intensive acoustic trauma.

This study examined knowledge and hair care behaviors of hair and scalp on UV(ultraviolet) comparing beauty care major and non-major female students. Results were obtained by questionnaire in 159 students majoring in beauty care and 198 students not majoring, was used frequency analysis, varimax rotation, t-test, F-test, Tukey post test. The analysis was statistically processed by using SPSS 12.0 program. The knowledge of hair and scalp on UV associated with a major showed significant on hair damage, in the UV, hair, scalp, hair damage, and UV and hair-related items, suggesting higher level in major female students. The results of care behaviors of UV and hair and scalp knowledge associated with a major. Correlation of care behaviors with a major showed significant results. For correlation by subfactor, there was significant difference in self-care, habitual care, and washing care between two groups, but there was no significant difference in protection care. It was found that both major and non-major students did not receive professional care.

In this research, with a goal of lessening the damage to hair by adding rose hip extract to permanent wave 1 solution and performing permanent wave procedure prior to acid dyeing and maximizing the effect of the procedure, rose hip extract 15%, 20% was added to each thioglycolate 1 solution and cysteine 1 solution and the procedure was performed. As a result, when performing the procedure by adding rose hip extract to permanent wave 1 solution thioglycolate and cysteine permanent wave 1 solution, the effect of wave effectiveness is increased and the damage to hair was confirmed to be low. Depending on the rose hip additive status in thioglycolate, the treatment effect of hair was shown to be beneficial. However, the limit of this research is that the thickness of hair strands for each person differs as well as the location of the hair contributing to the difference and therefore exact judgement regarding the shape of waves as well as the level of damage cannot be fully measured. In the following clinical tests, we will test the procedure on variety of hair types.

과산화수소에 의한 모발의 화학적 손상을 SEM/EDS, CLSM, FT-IR을 통해 평가하였다. SEM/EDS상에서 과산화수소 처리된 모발은 미처리 모발에 비해 표면의 비늘구조 사이의 간격이 벌어졌고, 구성원소를 분석한 결과 황의 비율이 감소하였으며 산소의 비율은 상대적으로 증가하였다. CLSM 관찰 결과 미처리 모발은 강한 형광을 나타내었지만, 탈색모발은 낮은 형광을 보여주었다. 이는 미처리 모발의 경우 자동형광을 나타낼 수 있는 방향족 아미노산이 많이 존재하는데 비해, 탈색모발은 방향족 아미노산이 파괴되어 형광이 낮게 나온 것으로 볼 수 있다. 또한 FT-IR 분석결과 탈색의 증가에 따라 시스테인산(cysteic acid)이 증가되었으며, 이는 폴리펩타이드 사슬사이에 다리결합을 하고 있는 시스틴의 산화에 의한 것으로 볼 수 있다. 이러한 결과들은 산화적 손상이 S-S 결합을 파괴하고 모발 섬유의 인장력을 낮추어 주는 것을 의미한다.
