Background and Objectives Low-level laser therapy (LLLT) is used widely to promote hair growth in androgenetic alopecia (AGA). This study examined the clinical efficacy and safety of a home-use LLLT device with a newly designed array of light sources and software optimized for individual types of AGA. Materials and Methods The study was a randomized, double-blind, sham device-controlled trial. Forty-eight subjects (39 men and nine women) were assigned randomly in a 2:1 ratio to use either the test device (LG Pra'L HGN1, LG electronics, Korea) or sham device. The subjects used the LLLT device three times a week for 16 weeks. Phototrichogram was used to measure the hair density and hair thickness at 0, 8, and 16-weeks. Adverse events were closely monitored. Results After 16 weeks of using the device, the test group showed a significant increase in hair density and hair thickness compared to the control. In the test group, the hair density increased 6.96 counts/cm² at eight weeks and 13.67 counts/cm² at 16 weeks from the baseline. The hair thickness increased 7.21 ㎛ at eight weeks and 11.80 ㎛ at 16 weeks compared to the baseline. Conclusion The home-use LLLT device with a novel array of light sources and an individualized program according to the types of hair loss appears to be an effective and safe treatment modality for both male and female AGA patients.

This study looked into the effect of the life style of single females in 20s and 30s on beauty behavior recognition, and spss 17.0 is used for data analysis method. As for the statistical analysis method in order to validate the measurement tools, reliability verification is conducted and life style groups are sampled using K-means taking into account factor scores by life style. To find out the difference between general beauty behavior recognition and life style, descriptive statistics and One Way ANOVA were carried out, and Duncan Test was implemented for the post examination method. Multiple regression analysis was also carried out to figure out the effect of life style on beauty behavior recognition. The result is as follows. First, according to the results of reliability verification and factor analysis for the lifestyle type and the recognition of the behavior for beauty, the types of the life style of the subjects were divided into Economic Utility, Convention Conservatism, Self Development, Showy Consumption, and Appearance Oriented, and the recognition of the behavior for beauty was named as Makeup and Hair, Cosmetic Surgery, Body Care, and Skin Care. Second, as to the recognition of the behavior for beauty based upon the lifestyle, the Appearance Oriented in Showy Consumption recorded the highest. Third, the analysis of the influence of the style on the recognition of the behavior for beauty showed that the behavior recognition for Makeup and Hair and for Skin Care was affected by the life style of Self Development, Showy Consumption, and Appearance Oriented; the behavior recognition for Cosmetic Surgery was affected by the life style of Conventional Conservatism, Showy Consumption, and Appearance Oriented; and again the behavior recognition for Body Care was by that of Economical Utility and Showy Consumption.

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.

As the importance of the beauty to pursue beauty comes to the fore, the market size of hairdressing industry including hair dyeing is getting bigger. In case of continuously applying an oxidative dyeing agent commonly used in hair salons, as hair damage is inevitable, we investigated morphological changes of hair treated with a neutral oxidative dyeing agent. In the experiment results, Between the control and the 6N-7N experimental groups, there was a significant difference in Max. modulus and Tangential modulus according to Max. load, Max. stress, Max. elongation, Break load, Break stress, Break elongation, and strain section. There were the highest values in Max. load, Max. stress, Max. elongation, Break load, Break stress and Break elongation in the control group, and there was no tendency to decrease significantly according to the treatment of the experimental group. Max. modulus and Tangential modulus according to the strain evaluation section did not show a tendency to increase or decrease constantly, although there was a difference between the control and experimental groups. This study attempts to provide basic data for the development of oxidative dyeing agent that minimizes hair damage and to establish the foundation for understanding the correlation between hair designers' oxidative dyeing agent and hair health.

This research is the hair damage as treating a permanent wave before and after that is compared and analyzed the change of physical and mechanical properties. This is the survey of women's hair in 20 years old. On the basis of this we would like to analyze a extend of hair damage. Also, we would to show a basic data for hair damage prevention and hair improvement to keep the beautiful and healthy hair. The conclusion is as follow. : The swelling degree after the treatment was found to be greater than before permanent wave treatment. For the formational characteristics wave, untreated hair certainly had more elastic S curl wave than damaged hair in all the permanent wave treatments, and damaged hair and extremely damaged hair had less elasticity and had saggy S curl wave. The protein permanent and soft permanent wave had thicker, gorgeous, and better elastic wave than the regular permanent wave and direct heating permanent wave in all the hair condition. As the degree of damage on hair got greater, the tensile strength dramatically decreased and as the degree of damage got greater, the elongation was great as well. For treatment method, direct heating permanent wave showed the greatest effect, causing the most damage.
