Objectives : The purpose of this study is to compare hair and alopecia of Korean Medicine with those of western medicine. Methods : We studied relationships between hair and essense(精), qi(氣), blood(血), five vicera(五臟) and meridians(經絡) through literature review about hair and alopecia. We compared Korean medicine with western medicine on physiology of hair and treatment of alopecia based on the study. Results & Conclusion : 1. Congenital essense(先天之精) is related with genetic factor and acquired essence(後天之精) is connected with nutritional factor. Defending function of Defense qi(衛氣) is related with immune reaction and qi stagnation(氣鬱) is associated with stress reaction. Atrophy of vascular tissues observed in alopecia scalp means deep relationship between blood(血) and alopecia, further deficiency of blood can cause telogen effluvium. 2. Kidney qi(腎氣) is related with inhibiting combination of Androgen receptor and Dihydrotestosterone(DHT) or activating hair growth factior. Pi(脾) is connected with alopecia seborrheica caused by damp-heat(濕熱) and alopecia areata caused by excessive prudence(思慮過度). Heart(心) is associated with atrophy in vascular tissue of scalp and liver(肝) is connected with metabolism. 3. Armpit hair and pubic hair as secondary sex characteristics are realated with Yangming Meridian(陽明經) and beard and hair at crown part where Type II $5{\alpha}$-reductase is activated much are associated with Taiyang Meridian(太陽經). 4. Juglandis Semen pharmacopuncture and Ganoderma lucidum pharmacopucture have better effects on inhibit $5{\alpha}$-reductase than Finasteride. Minoxidil and PRP are similar with promoting blood flow and removing stasis(活血祛瘀). Seven-star needling(七星針) is similar with microneedling. 5. Alopecia can be caused by due to lack of circulation Views we need solution to improve circulation coincide in opinion with Korean Medicine and Western medicine.
Human umbilical cord blood mesenchymal stem cells (hUCB-MSCs) are used in tissue repair and regeneration; however, the mechanisms involved are not well understood. We investigated the hair growth-promoting effects of hUCB-MSCs treatment to determine whether hUCB-MSCs enhance the promotion of hair growth. Furthermore, we attempted to identify the factors responsible for hair growth. The effects of hUCB-MSCs on hair growth were investigated in vivo, and hUCB-MSCs advanced anagen onset and hair follicle neogeneration. We found that hUCB-MSCs co-culture increased the viability and up-regulated hair induction-related proteins of human dermal papilla cells (hDPCs) in vitro. A growth factor antibody array revealed that secretory factors from hUCB-MSCs are related to hair growth. Insulin-like growth factor binding protein-1 (IGFBP-1) and vascular endothelial growth factor (VEGF) were increased in co-culture medium. Finally, we found that IGFBP-1, through the co-localization of an IGF-1 and IGFBP-1, had positive effects on cell viability; VEGF secretion; expression of alkaline phosphatase (ALP), CD133, and ${\beta}-catenin$; and formation of hDPCs 3D spheroids. Taken together, these data suggest that hUCB-MSCs promote hair growth via a paracrine mechanism.
Background: A wide range of environmental factors, such as diseases, nutritional deficiencies, ageing, hormonal imbalances, stress, and ultraviolet (UV) radiation, may affect the structure and function of the skin that covers the entire surface of the human body. In this study, we investigated roles of red ginseng oil (RGO) in enhancing skin functions, including hair growth and skin protection, using mouse models. Methods: For hair growth experiment, shaved dorsal skins of C57BL/6 mice were topically applied with vehicle, RGO, RGO's major compounds, or minoxidil for consecutive 21 days and skin tissues were examined the hair growth promoting capacity. For skin protection experiment, SKH-1 hairless mice were topically applied with vehicle or RGO twice a day for three days prior to exposure to UVC radiation at 20 kJ/cm2. Skin tissues were collected to evaluate skin protective effects of RGO. Results: Topical application of RGO to C57BL/6 mice effectively promoted hair regeneration by inducing early telogen-to-anagen transition and significantly increasing the density and bulb diameter of hair follicles. Major compounds, including linoleic acids and β-sitosterol, contributed to RGO-promoted hair growth. Treatment with RGO as well as its major components upregulated expression of hair growth-related proteins. Furthermore, in SKH-1 hairless mice, RGO had a protective effect against UVC-induced skin damage by inhibiting inflammation and apoptosis, as well as inducing cytoprotective systems. Conclusion: These data suggest that RGO may be a potent agent for improving skin health and thereby preventing and/or treating hair loss and protecting skin against UV radiation.
This study analysed the mercury concentration in the hair of 62 students (male : 21, female : 41) of D university in Najusi, Jeon-Nam area. Also, questionnaire, which developed by NIES, were completed by the students. According to the questionnaire, most of the students had a higher intake of meat than that of fish. Also, among the students, there were many smokes and many had dental treatment with amalgam. Based on the gender, female showed 1.024 ${\mu}g/g$ and male showed 0.882 ${\mu}g/g$ of the mercury concentration. This means that female students had higher level of mercury in their hair, but it was not a significant statistic difference. Comparing by the intake frequency of meat, processed food stuffs, protein foods, it shows the more they at the higher mercury concentration was observed. According to the intake frequency of fish, when the number of times they intake increased, the mercury concentration was higher. Under one time was 0.857 ${\mu}g/g$ and twice or more times were 1.152 ${\mu}g/g$, which showed a significant statistical difference (p<0.05). Depending on the Life style, the mercury concentration in the hair was high with workout, outdoor activities, and direct smoking. The mercury concentration in the hair showed no difference for whether they received amalgam treatment but the personal dietary habit and the Living condition affects strongly on the mercury concentration level.
This study was carried out to examine the action mechanism of Chamaecyparis obtusa oil (CO) on hair growth in C57BL/6 mice. For alkaline phosphatase (ALP) and ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GT) activities in the skin tissue, at week 4, the 3% minoxidil (MXD) and 3% CO treatment groups showed an ALP activity that was significantly higher by 85% (p < 0.001) and 48% (p < 0.05) and an ${\gamma}$-GT activity that was significantly higher by 294% (p < 0.01) and 254% (p < 0.05) respectively, as compared to the saline (SA) treatment group. For insulin-like growth factor-1 (IGF-1) mRNA expression in the skin tissue, at week 4, the MXD and CO groups showed a significantly higher expression by 204% (p < 0.05) and 426% (p < 0.01) respectively, as compared to the SA group. At week 4, vascular endothelial growth factor (VEGF) expression in the MXD and CO groups showed a significantly higher expression by 74% and 96% (p < 0.05) respectively, however, epidermal growth factor (EGF) expression in the MXD and CO groups showed a significantly lower expression by 66% and 61% (p < 0.05) respectively, as compared to the SA group. Stem cell factor (SCF) expression in the MXD and CO groups was observed by immunohis-tochemistry as significant in a part of the bulge around the hair follicle and in a part of the basal layer of the epidermis. Taking all the results together, on the basis of effects on ALP and ${\gamma}$-GT activity, and the expression of IGF-1, VEGF and SCF, which are related to the promotion of hair growth, it can be concluded that CO induced a proliferation and division of hair follicle cells and maintained the anagen phase. Because EGF expression was decreased significantly, CO could delay the transition to the catagen phase.

In this study, we tried to investigate the efficacy of combined light therapy using low-power lasers at 655 nm and LEDs emitting wavelengths at 625 ± 5 nm and 850 ± 10 nm in hair loss and scalp. A total of 33 subjects were enrolled in this clinical trial. Each subject used the LLLT and LED device on the scalp for 10 min on a daily basis for 12 weeks. After 12 weeks of LLLT and LED device use, there were significant improvements in redness, elasticity, and hydration of the scalp. Additionally, hair luster and tensile strength were improved. A remarkable decrease in total shed hairs was observed in all subjects at 4, 8, and 12 weeks without any serious adverse event. Combined light therapy using LLLT and LEDs proved to be an effective treatment for reducing hair loss and improving scalp condition.

This experiment was investigated the effects of fresh and ginger processed Pinelliae Rhizoma extracts on hair growth activity, and its fractions(chloroform, ethyl acetate and water fractions) obtained from fresh Pinelliae Rhizoma on hair growth activity of the normal and spontaneous alopecia areata model of C57BL/6N mice for 16 days. The results were as follows: In fresh Pinelliae Rhizoma extracts treated group, hair growth effect was observed in whole skin area(100%) all the normal mice in whose hair had been clipped on 16th days. In ginger processed Pinelliae Rhizoma extracts treated group, hair growth effect was observed in whole skin area in 25% of normal mice in whose hair had been clipped on 16th days. But in control group, hair growth effect was observed in a part of whole skin area in 25% of normal mice. In fresh Pinelliae Rhizoma extracts treated group, hair follicles of middle stage of anagen phase was observed and it were grown down to subcutaneous tissue of skin in all the mice on 10th day. But in ginger processed Pinelliae Rhizoma extracts treated group and control group, Most of hair follicles of telogen phase was observed in skin. The treatment of extracts of fresh Pinelliae Rhizoma increased the expression of TGF-$\beta$(146%), IGF(107%), and prolactin(115%) in the skin of normal C57BL/6N mice compared to control group(100%). But expression of placenta lactogen(93%) was decreased in the skin of normal C57BL/6N mice compared to control group(100%). In spontaneous alopecia model, The hair growth activity of fresh Pinelliae Rhizoma extracts treated group(100%) was observed to be strong compared with the control group(20%) on 15th day. Hair growth activity on chloroform fractions of fresh Pinelliae Rhizoma extracts was observed in whole skin area in 75% of normal mice on the 9th day. In water and ethyl acetate fractions, hair growth activity was observed in a part of whole skin in 75% and 25% of normal mice, respectively. but hair growth activity of control group was not observed. After application of fractions of fresh Pinelliae Rhizoma extracts for 10 days, hair follicles of chloroform fraction treated group was observed middle stage of anagen phase and hair follicle were grown down to subcutaneous tissue of skin in all the mice. But hair follicles of initial stage of anagen phase were observed in water and ethyl acetate fractions. Most of hair follicles of telogen phase was observed in skin of control group. These experiments suggest that extracts of fresh Pinelliae Rhizoma may stimulate the topical hair growth activity and its chloroform fractions can be useful for treatment of alopecia areata.
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.

Mylabris is the dried body of the chinese blister beetle. The species used in medicine are Mylabris phalerata and M. cichorii. In recent studies, it has been found that Mylabris possesses antitumor properties, increases the number of leukocytes, and has irritant effects on the urinary organs. The crude extracts of Mylabris have been noted for their highly irritant action and other traditional uses of Mylabris include treatment of poor local blood circulation. The active constituent of Mylabris is cantharidin. The chemical is notable for its vesicant properties, but with severe side effects such as nephrotoxicity. This experiment examined the effect of extracts and fractions, obtained from Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. First, we examined the effect of an extracts, obtained from the alcohol extracts of dried Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. Second, we examined on hair growth activity of the cantharidin fraction of Mylabris phalerata Pall. compared to the control and 1% minoxidil groups. Third, we investigated the number of hair follicle and mast cells after topical application of extracts of Mylabris phalerata Pall. to skin for 16 days. The results were as follows: Hair growth effect from the extracts of Mylabris phalerata Pall.(0.312%) was observed in 80% of mice whose hair had been removed in 13 days. Hair growth effect from the extract of Mylabris phalerata Pall.(0.312 and 0.625%) and 1% minoxidil group was observed in 100% of mice whose hair had been clipped in 20 days. Hair growth effect from the cantharidin fraction(0.5%) and water fraction(0.5%) of Mylabris phalerata Pall. was observed in 100% of mice whose hair had been clipped in 24 days. The hair growth effect on the cantharidin fraction(0.125%) was observed to be strong compared with the minoxidil(3%) group, commercial hair growth agents, in mice whose hair had been clipped in 19 days. In the spontaneous alopecia mice model, the hair growth effect from the cantharidin fraction (0.125%) was observed to be strong as compared with the states before the 13 days experiment. These experiments suggest that extracts and fractions of Mylabris phalerata Pall. may stimulate the topical hair growth activity in low doses.
