We have studied anemarrhena asphodeloides, a hair growth promoter as an alternative medicine agent to compensate for the disadvantages of minoxidil, which has excellent hair growth promoting effect on follicular epithelial cells. anemarrhena asphodeloide, an Rhizome plant of aemarrhena asphodeloide family, is a traditional medicinal plant used in Korea as an antipyretic, antidiabetic, antidepressant, antiinflammatory. We applied and observed anemarrhena asphodeloides ethanol extracts to the back of mice, and there was no significant difference in body weight and food intake among all groups of mice. The ethanol extract of anemarrhena asphodeloides showed vigorous hair growth promoting effect without changing the serum composition and thus it is considered to be useful as a hair growth promoter in the future.

Astrigent persimmon fruit resources have been used traditionally to treat different systemic diseases and acclaimed for various biological activities including hair growth. This study investigates the hair restoration efficacy of astrigent persimmon fruit extracts on genetically predisposed to balding pattern Black mice model. Water extract of astrigent persimmon fruit(10 mg/mouse/day) with standardized vehicle formulation, only vehicle and positive control minoxidil (2%) were applied daily until completion of two full hair growth generations. The changing pattern of hair growth were observed through two hair growth generations of C57BL/6 Black mice. The hair existing area and hair length was increased significantly (P > 0.001) in astrigent persimmon fruit treated mice than vehicle-treated control mice. Furthermore, histological assessment revealed that the number of hair follicles did not remarkably increase after astrigent persimmon fruit treatment in compare to control mice. Thus, our data revealed that the topical application of astrigent persimmon fruit may promote hair growth in nude mice by extend the hair existing area and increase hair length which is an indicator of prolong anagen phase.

This study was conducted to evaluate the hair-growth promotion effect in C57BL/6 mice of a new substance mixed with Allium cepa (red)-bioconversion extract and Angelica gigas Nakai. The ethanol extract of Allium cepa (red) was bioconverted through the use of the Bacillus subtilis KJ-3 (BS3) strain, which was named Red-BCQ. The quercetin content of Red-BCQ increased by about 7.4-fold after bioconversion. Angelica gigas Nakai extract (Agnex) contains a large amount of coumarins such as decursin (D) and decursinol angelate (DA). A 1 mg portion of Agnex contained 0.4146 mg of D and 0.3659 mg of DA. Minoxidil has been known to promote hair growth. In this study, the hair-growth promotion effects of Red-BCQ, Agnex, and a mixture of both Red-BCQ and Agnex were compared with 5% minoxidil. Twenty-five mice were divided into five experimental groups including saline (CON), 5% minoxidil (PCON), Red-BCQ (RA), Agnex (AG), and a Red-BCQ-Agnex mixture (RAG)-treated group. Samples were administered orally once a day at a fixed time for 4 weeks. Hair growth was monitored by photograph at 7, 14, 21, and 28 days. We also observed 5α-reductase, alkaline phosphatase (ALP), γ-glutamyl transpeptidase (γ-GT), insulin-like growth factor (IGF)-1, transforming growth factor (TGF)-β1, antioxidant enzyme, and the hair follicles of the skin tissue. In all the results, the RAG-administered group showed greater antioxidative and hair-growth promotion effects than the other groups. These data suggest that RAG has potent stimulating activity on hair growth in C57BL/6 mice.

Tenebrio molitor samples were investigated as novel biomaterials and sources of food in several recent studies. However, the insects' effects on hair growth were not sufficiently researched. To develop novel and natural materials for preventing alopecia and promoting hair growth, this study investigated the antioxidant activities and hair-growth promotion effects of TMEs. To determine the antioxidant activities, the TMEs' DPPH radical- and nitrite-scavenging activities were examined. To determine hair-growth promotion effects, proliferations of human dermal papilla cells (DPCs) and the murine fibroblast cell line NIH3T3 were evaluated by using an MTS assay. In addition, estimations were made for cell viabilities against cell death induced by dihydrotesterone (DHT) in DPCs and inhibitory effects against potassium channel blocking induced by tolbutamide (TBM) in NIH3T3 cells. The DPPH radical scavenging activity was 81.17%, and the nitrite scavenging activity was 43.69%; the activities were similar to the activities of blueberry extracts. Moreover, the TMEs promoted the proliferation of human DPCs and NIH3T3 cells, which were concentrated dependently. The TMEs prevented not only DHT-induced DPC cytotoxicity but also TBM's action as a potassium channel blocker in NIH3T3 cells. The results suggested that TME could be used as a functional therapeutic alopecia reagent, to prevent hair loss and to promote hair growth.

Hair is an appendage of skin which protects the body from outer physical and chemical stimuli. Hair is generated from the hair follicle lying on a sunken basal layer of epidermis. Hair cycling, which regenerates hair follicles throughout the life time of the organism. Numerous kinds of factors which exist at the hair follicle have been reported to regulate hair cycling, Human growth hormone secreted from pituitary gland, initially demonstrated to accelerate organ's growth, has been reported to play a role in the biology of organ size determination. We investigated the effect of 6-histidines residues tagged at amino-terminus of human growth hormone using light and electronmicroscopic methods. Human growth hormone encapsulated in nano-liposome (LhGH) was used to find how LhGH affects hair follicle cycling of mouse (C57BL6/CrN). Distilled water as a negative control, 3% Minoxidil as a positive control, and LhGH were applied to mouse for weeks. LhGH increased the number of exposed hairs per given areas ($1mm^2$). This result was also confirmed using a different breed of mice which show natural hair loss in an old age (about 17 months after birth). When LhGH was applied for 3 weeks after natural hair loss, natural hair loss on these mice was prevented, However, the control group mice on which LhGH was not applied showed further hair loss. This result indicates that LhGH may stimulate hair cycling of mouse. In clusion, it is cleat that the LhGH increased the number of hair on mice and help the depilated skin to grow new hair follicles again.

The bacterial growth and pH of Pleuropterus cilinervis extracts and animal milk, fermented with Lactobacillus rhamnosus during the fermentation process, were evaluated. The results indicated that the bacterial count after fermentation always remained higher than 6 log CFU/mL, with a constant pH of approximately 4. In order to evaluate the effects of Pleuropterus cilinervis extracts and animal milk, fermented with Lactobacillus rhamnosus, on hair growth promotion, C57BL/6 mice were chosen as experimental subjects. Six week old males with similar body weights were divided into four groups; a normal group (saline), a negative control group (essence base), a positive control group and an experimental group (Pleuropterus cilinervis extracts and animal milk, fermented with Lactobacillus rhamnosus, mixed with negative control). The substances and test materials were applied topically on the back skin of the mice for 8 days. Other external conditions and variables such as food intake were kept at the same as the four groups. At the end of the experiment it was noted that hair re-growth in the experimental group, using gross and histological examinations, was higher than that in the positive control group. This study therefore provides an empirical evidence that Pleuropterus cilinervis extracts and animal milk fermented with Lactobacillus rhamnosus promotes hair growth, and suggests that applications could be found in hair loss treatments.

This study was performed to confirm the antioxidative and hair-growth-promotion effects of a fermented compound composed of five materials, namely Allium cepa, Cucurbita spp., Glycine max Merr., Pinus sylvestris leaf, and Sesamum indicum. An additional compound composed of two materials was composed of Allium cepa and Cucurbita spp. Antioxidative effects were measured based on DPPH radical-scavenging activity and total flavonoid content. Fermented 5-type natural compounds (5NC) showed higher DPPH radical-scavenging activity and flavonoid content than those of fermented 2-type natural compounds (2NC). Hair-growth promotion was demonstrated in vivo. Alkaline phosphatase (ALP), oid contentontenteptidase phospactivity, and macroscopic observation were measured. Experimental animals were divided into four groups based on the samples they were administered: water, pansildil (P-CON), 5NC, and 2NC. Samples were administered orally once a day at a fixed time for four weeks. Both ALP and ${\gamma}eeksactivity$ increased in the 5NC group compared with the 2NC group. In macroscopic observation, the P-CON group grew the most and were most similar to the state before shaving. The 5NC group grew hair similar to the P-CON group. In all the results, the 5NC group showed greater antioxidative and hair-growth-promotion effects than the 2NC group. Consequently, 5NC could be used as an ingredient for hair-growth promotion.

It is commonly believed that black soybean (Glycine max: BB) prevents and alleviates hair loss. However, few studies have directly assessed the effect of BB on hair growth. We presently evaluated the mitosis induction on dermal papillae cell and mitogenic effect on NIH3T3 cells in vitro. To elucidate the hair growth promoting effect in vivo, anagen induction and hair restoration were examined in a shaving model of C57BL/6 mice. We also conducted biochemical analysis of blood plasma. Significant stimulation of dermal papillae and NIH3T3 cell proliferation were observed by treatment of BB in a dose-dependent manner. BB markedly promoted hair growth and significantly improved blood total antioxidant capacity and reduced lipid peroxidation and triglyceride level. These results suggest that BB has hair growth promoting effect and it is a potent candidate for the prevention of hair loss.

Streptococcus sp. is generally known as a strain that produces hyaluronic acid. In this study, we focused on ingredients other than hyaluronic acid among several metabolites produced by Streptococcus sp. during cultivation. The hair experimental sample (HAIRCLE^TM) was prepared with Streptococcus sp. culture filtrate under the condition that hyaluronic acid was not produced and the effect on the hair was identified. Tensile strength of hair was tested with a universal testing machine (UTM). Surface properties of a hair were examined with an atomic force microscope (AFM). Our results suggest that HAIRCLE^TM could prevent damage to a hair such as destroyed-cuticle, increased-faction force, and broken-hair. Furthermore, hair-related experiments confirmed that HAIRCLE^TM could promote the expression of hair growth factors VEGF, HGF, and Wnt10b and mitigate male hair loss by inhibiting androgen receptors and TGF-β2 expression. In addition, it was confirmed that the expression of barrier-related factors (INV, CLDN-1) was increased for oxidative stress, and the COX-2 expression, an inflammatory factor, was inhibited, thereby improving damaged scalp barriers and alleviating induced inflammation.

This study investigated the effect of herbal extracts fermented by Lactobacillus plantarum (MBN) on hair growth in C57BL/6 mice and HaCaT cells. Five week old mice were applied with MBN topically (0.2 mL) once per for 21 days. Hair regrowth was evaluated by gross examination and verified by hematoxylin-eosin staining. Gene expression of vascular endothelial growth factor (VEGF), keratinocyte growth factor (KGF), and transforming growth factor-beta1 ($TGF{\beta}1$), relevant to hair growth, were examined. The data revealed that MBN successfully promoted hair growth in both male and female mice at a dose between 200-500 mg/kg and improved hair thickness. The VEGF and KGF genes were expressed in a dose-dependant manner, whereas $TGF{\beta}1$ was not expressed. Moreover, nitric oxide was significantly increased, suggesting an improvement in blood flow. These results indicate that MBN effectively promoted hair growth and gene expression relevant to hair growth in an animal model.
