Hair is the part of body which expresses man into more manlike. When we create some artworks, we need the most suitable material for the artworks. Similarity, the healthy scalp hair condition and treatment are required to keep our hair clean and healthy. And the improper condition of scalp hair prohibits our hair from normal growing, proceeds the alopecia(loss of hair) and double our physical and mental stresses. The necessity of health treatment of scalp hair which was damaged by frequent permanent hair wave and hair coloring is on the rise. This study will present how to control and treat the scalp hair and will check how we feel about the necessity of scalp hair treatment. This study finally shows that people think their scalp hair conditions are not normal and chemically treated hair in spite of their natural hair. However, most people think that the scalp hair treatment is very useful to their hair and this result enables us to predict the future market of the scalp hair treatment business will be growing day by day. We need to study further not only scalp hair treatment but also prevention stage in order to keep the healthy hair and will check how we feel about the necessity of scalp hair treatment.

Hair manicure is usually and widely operated in the area of hair-dyeing by the reason that acidic hair color is less damaged and more stable than other chemical color treatment. However, there is no an in-depth study to prove them. This study purposes to provide basic resources for effectively using products of hair manicure by experiments on Physical Properties of Hair. Hair of one healthy woman in mid-20's, Level 4, was sampled for experiments. For the tests, hair samples were classified by the frequency of hair manicure treatment The control group(a), once treatment(b), twice(c), three times(d), four times(e) and five times(f). The results were measured with Scanning Electron Microscopy(SEM) and Tensile Strength and Elongation test. The lower Values of Tensile Strength according to repeated hair manicure treatment. Elongation is not affected by the frequency of hair manicure treatment. There was no remarkable change of hair surface in once(b) and twice(c) treatment. The change of hair surface which was able to judge by cuticle layers looseness, tunics and the transformation of cuticle cell were observed in the hair samples operating more than three times(d) of hair manicure treatment.

This study intends to find out possible variations in physical properties and color of hair depending on dye type(acidic and alkalic) and permanent treatment/hair dyeing procedure. To meet the goals, healthy hair samples were taken from 5 women's hair speciment in 20's without experiencing in any harmful substance via long-term medications. and beauty care using chemicals. To get possible findings depending upon hair dye type and treatment procedure, both acidic and alkalic hair dye were applied on some specimens after permanent treatment, while on other specimens before permanent treatment. In order to determine scale damage, this study used SEM(Hitachi S-2500C) both hair thickness and tensile strength were measured with optical microscope(Nikon, MM-60/L3T) and Instron (4482-standard). Wave configuration was measured transverse and longitudinal round diameter. The chromaticity of each specimen was measured using a spectrocolorimeter(Color Techno System, JP/JX-777) with visual $C/2^{\circ}$ (at $2^{\circ}$ with C light source) monitor fixed to determine Lab and CMYK values. As a result, it was found that hair specimens were more significantly damaged with alkalic hair dye treatment than with acidic hair dye treatment, while hair specimens were more effectively dyed with the former hair dye type than with the latter one. For possible results depending on treatment procedure, it was found that hair specimens were less damaged but more effectively dyed with permanent treatment followed by hair dyeing than vice versa. Therefore, it was concluded that permanent treatment followed by acidic hair dyeing would be more effective in reducing hair damages.

This study aims to propose a method to reduce hair damage after investigating the following: the factors which vary depending on hair treatment conditions; the degree of hair damage in the bleached sample; and an analysis of the effects of a perm on wave formation. To determine the effects of these treatment types, hair bleach was mixed with the hair treatment, and hair damage and formation of permanent waves were examined. Using a scanning electron microscope, in addition, morphological changes were analyzed and the following results were obtained: After mixing natural powder(2.5g) and hair cream(2.5g) and bleaching the mixture, it was compared to the scale structure of untreated hair. When 5g of natural powder was mixed and bleached, a clear layer was observed among cuticle scales, showing the effects of hair treatment. Therefore, this confirms that the effects of hair treatment were most notable when grain powder was mixed with hair cream. Once hair is damaged, it is almost impossible to regain its original state. When chemical agents are used, therefore, it is important to consider the possible hair damage they cause.

This study was designed to measure customer awareness about their own scalp and hair treatment based on survey, through the theoretical background of scalp physiology field by considering scalp and hair treatment. This was to provide a principal data about scalp and hair treatment for the beauty industry. Also, the data about the awareness of customers will be used to search for a direction far basic beauty services in the scalp and hair treatment field. Four hundred customers in beauty parlors, dermatology clinics, skin care institutes, and scalp institutes, living in the North Cheolla Province were surveyed. They were 25 years old and over. The surveys were performed over a period of ten days from November 18th to 28th in 2005. The collected data was analyzed by SPSS. Frequency and percentage were used to draw typical feature of subjects. Chi-square test, frequencies, t-test and One-way ANOVA were performed to consider awareness of customers for hair treatment as well as hair character and scalp hair. This study was able to estimate the awareness of customers by putting together between the recognition of scalp based on the special quality of hair and the recognition of hair and scalp treatment. In conclusion, the scalp and hair did not act independently. In order to have healthy hair, one must posses a healthy, and physiologically sound scalp. In order for beauticians to properly serve their clientele who require hair and scalp treatment, one must be able to comprehend and understand the field of scalp and hair treatment.

These days hair perm and dye is a modern trend that women prefer to create their own image and personality. However, chemicals for hair perm and dye are easy to damage hair. This study, then, is to find out some effective skills to minimize hair damage when hair perm and dye is done in a same time. The subjects were 200 hairs picked from five healthy women in their twenties which have not been permed and dyed since one year and more ago. The experimental group was divided into two groups: 1)the perm- nutritional treatment- dye (PNT) group 2)the dye- perm- nutritional treatment(DPN) group. After experiments, the states of "hair scale", "hair damage", and "color tone in dyed hair" were compared between two groups. The results are as follows: to lessen hair damage when hair perm and dye is done in a same time, nutritional treatments must be necessarily used on hair. To make hair colored more clearly when hair dye is done, it is more desirable to use nutritional treatments on hair.

The present study was to investigate the effects of different types of conditioner on the morphological changes of hair cuticles after coloring treatment. The virgin hair, aged 22 years served as a subject. Coloring treatment was done with a commercial hair dye agent for 35 minutes as routine procedures at $25^{\circ}C$, 50% R.H. environmental condition. The two different types of conditioner, Essence and LPP were applied to the colored hair 10 times with 2 days interval for 20 days. The hair cuticles were observed by a scanning electron micro scopy before and after coloring and conditioner treatment. The main results were as follows. Coloring treatment damaged the hair cuticles, and both of Essence and LPP had a direct conditioning effect. Also, the damaged hair cuticles were recovered by the repeated application of hair conditioner. Moreover, LPP was more effective in hair curing compared to Essence. These results show that a hair conditioner can be helpful to keep healthy hair and to shorten an interval of coloring.

Cordyceps militaris (CM) occurring from a fruiting body by a host insect is a kind of mushroom, which is composed of animal host and plant fruit body. CM contains large amounts of useful ingredients including polysaccharides, vitamins, amino acids, minerals, etc. The essential amino acids from CM including cystine, lysine, and methionine can be expected to improve damaged hair treatment as effective ingredients. In this study, the improvement effect of the CM extracts on chemical and physical properties for damaged-hair treatment was investigated. The cysteic acid and cystine monooxide produced by oxidation of cystine were analyzed their chemical structure by FT-IR spectroscopy. It was confirmed that the vibration absorption peak ($1,041cm^{-1}$) of cysteic acid was reduced and increased sulfur content considerably which means meaningful improvement effect on damaged-hair treatment. Apparently, the cuticle morphology of the damaged-hair was improved significantly by treatment with CM extracts. Especially, confocal laser scanning microscope images of the damaged-hair treated with the extract showed highly increased fluorescence intensity which means promising effect in hair treatment. The tensile strength of the damaged hair treated also increased by 168% compared with the damaged hair.

This study was performed to quantitatively and qualitatively estimate the effect of keratin essence on hair protection against physicochemical damage. Damaged hairs were obtained from an early thirty woman who dyed her hair two times and did digital permanent treatment of her hair two times. The damaged hairs were divided into four experimental groups, which are the control hair (CH) group without additional beauty treatment, the damaged hair (DH) group by additional dyeing treatment, basic essence-treated hair (BEH) group, and keratin essence-treated hair (KEH) groups according to the research goal. The protection effect of keratin essence against the physicochemical damage was quantitatively compared by difference of chrominance measured using a color difference meter and qualitatively compared by difference of outer morphological structure images pictured using scanning electron microscopy (SEM). The brightness and yellowish blue color of KEH were relatively lower but the reddish blue color was relatively higher than other groups of test hairs. Cuticle structure of the previously DH was irregularly deformed and more strongly deformed or partially broken by additional dyeing treatment. On the other hand, the gaps between cuticle scales of the DH were reformed by treatment with basic essence and reformed and filled by treatment with keratin essence in comparison with the DH group. Conclusively, the keratin essence was effective to protect hair structure against the structural damage induced by the dyeing-treatment, by which the coloring efficiency is thought to be improved.
