  • To investigate the effects of antioxidant activities and hair loss prevention of extracts from Platycodon grandiflorum, we've prepared chloroform (CF) and ethylacetate fractions (EA) extracted from P. grandiflorum. In the results of DPPH radical scavenging assay, the two fractions showed dose-dependent antioxidant activities. Furthermore, in the ABTS assay, the two fractions exhibited the inhibitory effect over 90% at 10, 50, 100, 200 mg/mL. To investigate the inflammation inhibitory effect, we used RAW264.7 cells, these extracts were inhibited inflammatory reaction by suppressing the production of nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) in dose-dependent manner. In the assay of HaCaT cells' proliferation, the 24 hr treatment of the extracts significantly accelerarted cell proliferation in the range of concentrations used. The two fractions inhibited the proliferation of Malssezia furfur, the bacteria induce the dandruff. Finally, the CF could significantly inhibit the DHT production at 1, 10, 50, $100{\mu}g/mL$, but EA showed the inhibitory effect at the concentration over $50{\mu}g/mL$. The overall results of this study suggest that the chloroform (CF) and ethylacetate fractions (EA) from P. grandiflorum could be a useful raw material for the hair loss prevention products.

  • The objective of this study is to find out the effect of yeast on hair loss treatment and the role of hair follicle stem cell activator, which is important in hair growth. The authors have recently produced a substance, which has no disgusting odor, does not precipitates and does not easily corrupt, to use instead of yeast acquired from raw rice wine(Makgeolli). The substance is named Yeast Constituent Extract(YCE). In this research, the Produced YCE was applied on the hair loss area of 10 Androgenic alopecia patients, twice every day for 6 months, in order to test the effect of hair loss treatment and the role of stem cell activator. As a result, all of the patients showed a significant growth of hair after 3 months of test, and showed much more growing, thickening and strengthening of hair after 6 months. As a result of measuring the number of hair strings in the same scalp region of the patients after 6 months, it is found that the density of hair has increased, indicating that the hair loss treatment was effective. Also the hair follicle stem cell was isolated from the patients and the contents of growth factors (IGF, VEGF, FGF, HGF) derived from hair follicle stem cell were measured with ELISA. As result, the amount is found to be about 10 times greater than before the test. The hair follicle stem cell contains many growth factors that affect growth of hair, so it takes a highly important role in hair loss treatment. The YCE that the authors have produced was found to be effective in increasing the contents of growth factors that are derived from hair follicle stem cell. Thus it can be inferred that the YCE plays a role as a stem cell activator that activates the hair follicle stem cells. In conclusion, the YCE is considered to be highly effective for hair loss treatment and to have a role as a stem cell activator.

  • The recent development of methods for culturing hair follicles in vitro has proved an important tool to investigate many aspects of drug screening. Human hair follicle is composed of multiple types of cells, whose interactions regulate morphology and cycling-anagen, catagen, and telogen. Many investigators have tried to develop models to prolong of the period of hair elongation in vitro. However these are limited in submerged culture, which don't work due to the lack of cell-cell interactions which are abundant in vivo environment. So we applied dermal equivalent (DE) to culturing flair follicles to prolong hair growth period.

  • After artificial intelligence was trained with the data on the concentration of essential mineral elements in hair, the age was predicted by the concentration of mineral elements in the hair of the subject, and the result was compared with the actual age of the subject, and the correlation was investigated. The total number of hair data was 296, of which 2/3 were used for AI learning and 1/3 was used as the subject data. There was a correlation of 0. 678 between the actual age of the young subjects under the age of 25 and the age predicted by the AI. There was almost no correlation in the middle-aged subjects group, and there was a weak correlation of 0.522 in the elderly subject group. In order to secure the usefulness of artificial intelligence using hair mineral element concentration data, it is necessary to provide a larger number of data to the artificial intelligence.

  • As the importance of national technical qualifications for hairdressers to verify qualifications and skills as a professional is increasing, it is time to improve achievement motivation and job attitudes through research on job attitudes perceived by hair designers toward hair practical tasks. As a result of studying the effect on the job attitude of a hairstylist working in a hair salon, it was found that blow-drying induced the hairstylist's job efficacy among the practical tasks for the hairdresser's hair national technology certification, and scalp scaling and shampoo were the job of the hairstylist. was found to induce satisfaction. Based on the research results, it is possible to present a variety of practical certification tasks with practicality that can be usefully applied to customers in various techniques in the beauty industry, rather than unrealistic practical techniques limited only to wigs. We want to induce improvement. In addition, I believe that this study will provide basic data for the development of various practical tasks to improve the achievement motivation of hair designers.

  • We successfully isolated human anagen hair follicles from human scalp skin by microdissection and tried to culture them under various conditions. First we confirmed negative effect of serum on human hair follicle organ culture. As a next step serum-free medium compositions, Philpott medium, IMDM, and DHGM (Dongguk hair growth medium) were tried. Philpott medium is a general medium for hair organ culture based on Williams' E medium and DHGM is a special self-developed medium containing high amino acids and vitamins (B group) composition. As results, hair follicle in Philpott medium and IMDM showed anagen phase morphological structure, but rapid loss of hair elongation, low alkaline phosphatase expression, and very low expression of CK19. It is thought these hair follicles rapidly regressed from apoptosis. However, hair follicles in DHGM showed long term anagen phase morphological structure, continuous hair elongation, high alkaline phosphatase, and CK19 expression. These results demonstrate that high amino acids and vitamins (B group) composition are essential to in vitro long term human hair follicle organ culture and this culture medium will be useful in basic study of hair biology or application study to the development of alopecia treatment drugs.

  • Hair follicles develop as a result of epithelial-mesenchymal interactions between epidermal keratinocytes and dermal cells. Moreover hair follicles constitute multiple cells that influence hair follicle development and cyclic activity. We isolated some cells using explantation and enzymatic digestion method from human scalp hair follicles. So we could culture some follicular cells, such as outer root sheath (ORS) cells, dermal papilla (DP) cells, dermal sheath (DS) cells, matrix cells and melanocyte.
