To develop new therapy for prevention and treatment of hair loss is very important according to increase of the number of hair loss people. The aim of this study was to investigate the hair growth promoting effects of pectin lyase-modified red ginseng extract (GS-E3D). We examined antioxidant and anti-inflammatory effects, human hair dermal papilla cells (HHDPC) proliferation, and testoterone-induced $5{\alpha}$-reductase inhibitory effects. GS-E3D show not only 1,1-diphenyl-2-picryhydrazyl (DPPH) radical scavenging activity and xanthine oxidase inhibitory effects as an anti-oxidant property, but also lip-oxygenase and hyaluronidase inhibitory effects as an anti-inflammatory property. Human hair dermal papilla cells proliferation by GS-E3D was higher than those of minoxidil or finasteride, using the positive controls. Moreover, GS-E3D exhibited $5{\alpha}$-reductase inhibitory activities after stimulating by testoterone. The present results indicate that GS-E3D has a potential to be as an hair growth promoting agent for cosmetic materials.

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.

Full-thickness scalp burns secondary to hair coloring are rare; however, such defects can be large and complex reconstruction of hair-bearing tissue may be necessary. Many skin-stretching devices that use gradual traction have been applied to take advantage of the viscoelastic properties of the skin. A 21-year-old female patient was seen with a burn defect on her occipital scalp leading to exposed subcutaneous tissue after chemical application of hair coloring in a salon. The dimensions of the wound were $10cm{\times}5cm$, and a skin graft or flap would have been necessary to close the defect. Two long transfixing K-wires (1.4 mm) and paired 3-wire threads (23 gauge), which are readily available in most hospitals, were applied over a period of 12 days for trichophytic closure of the defect. The remaining scalp scars after primary trichophytic closure with this skin-stretching method were refined with hair follicle transplantation. This skin-stretching method is simple to apply and valuable for helping to close problematic areas of skin shortage that would otherwise require more complicated procedures. This case shows a relatively unknown complication of hair coloring and its treatment.

We investigated the effect of ultra-high molecular weight poly-γ-glutamic acid (UHMW γ-PGA) on hair loss in vitro and in vivo. 5-Alpha reductase is an enzyme that metabolizes the male hormone testosterone into dihydrotestosterone. By performing an in vitro experiment to analyze the inhibitory effects of UHMW γ-PGA on 5-alpha reductase activity, we determined that UHMW γ-PGA did in fact inhibit 5-alpha reductase activity, indicating the use of UHMW γ-PGA as a potential 5-alpha reductase inhibitor in the treatment of men with androgenetic alopecia. To evaluate the promotion of hair growth in vivo, we topically applied UHMW γ-PGA and minoxidil on the shaved dorsal skin of telogenic C57BL/6 mice for 4 weeks. At 4 weeks, the groups treated with UHMW γ-PGA showed hair growth on more than 50% of the shaved skin, whereas the control group showed less hair growth. To investigate the progression of hair follicles in the hair cycle, hematoxylin and eosin staining was performed. Histological observations revealed that the appearance of hair follicles was earlier in the UHMW γ-PGA-treated group than in the control group. The number of hair follicles on the relative area of shaved skin in the UHMW γ-PGA-treated group was higher than that observed on the shaved skin in the control group. These results indicate that UHMW γ-PGA can promote hair growth by effectively inducing the anagen phase in telogenic C57BL/6 mice.

In this research, I chose and studied colorless hair manicure, which is well known for its useful point and supplement damaged hair glossy, luster, elastic and soft one. Also I studied and found hair protection effect by the management time of colorless hair manicure products, as below. Both level 3 and level 6 hairs, when they get damaged after dyeing, both hairs' strength and enlargement are affected. Manicuring two weeks after dyeing is more effective way than manicuring right after dyeing. So, in case of making good hair quality in manicuring dyed hair, it's more effective to manicure right after dyeing to both level 3 and level 6 hair. To complement hair's damage, however, manicuring two weeks after dyeing is the best effective way.

Diabetes mellitus is one of the most prevalent diseases in modern society. Many complicationssuch as hepatic cirrhosis, neuropathy, cardiac infarction, and so on are associated with diabetes. Although a relationship between diabetes and hair loss has been recently reported, the treatment of diabetic hair loss by Wnt/β-catenin activators has not been achieved yet. In this study, we found that the depilation-induced anagen phase was delayed in both db/db mice and high-fat diet (HFD) and streptozotocin (STZ)-induced diabetic mice. In diabetic mice, both hair regrowth and wound-induced hair follicle neogenesis (WIHN) were reduced because of suppression of Wnt/β-catenin signaling and decreased proliferation of hair follicle cells. We identified that KY19382, a small molecule that activates Wnt/β-catenin signaling, restored the capabilities of regrowth and WIHN in diabetic mice. The Wnt/β-catenin signaling activator also increased the length of the human hair follicle which was decreased under high glucose culture conditions. Overall, the diabetic condition reduced both hair regrowth and regeneration with suppression of the Wnt/β-catenin signaling pathway. Consequently, the usage of Wnt/β-catenin signaling activators could be a potential strategy to treat diabetes-induced alopecia patients.

Objectives : In Korean medicine, a prescription of Sinsun-yukza-hwan (Shenxian-liuzi-wan, SSY) has been used in clinic for treatment of alopecia via oral. This study was performed to determine transdermal effects of the ethanol extract from SSY on hair growth and -related gene expressions in mice. Methods : We analyzed index compound, 5-hydroxy-methyl-2-furaldehyde (HMF), in SSY extract by ultra performance liquid chromatography (UPLC). 6 weeks old C57BL/6 mice with removed hair were used as an alopecia animal model. Mice were divided into 3 experimental groups including normal (3 water: 1 ethanol: 2 polyethylene glycol mixture as a vehicle), SSY extract and 5% minoxidil (as a positive control), treated groups. SSY was applied topically on the hair-shaved skin of C57BL/6 mice every day for 15 days. The color, thickness and density of hair were monitored every $5^{th}$ day by naked eye, photograph and phototrichogram using folliscope. Also hair growth-associated gene expressions were measured by immunoblotting assay. Results : Hair density of minoxidil or SSY-treated group was significantly increased compared to that of vehicle application on the $15^{th}$ day, respectively. And hair thickness of minoxidil and SSY groups was increased compared to that of vehicle treated group on the $15^{th}$ day, respectively. Induction of insulin-like-growth factor 1(IGF-1) and vascular endothelial growth factor (VEGF) were also significantly accelerated by SSY extract compared to those of vehicle-applied group. Conclusions : These results provide scientific evidence to support the potent multi-application of SSY as a cosmeceutical material for promoting hair growth.
