This study conducted frequency analysis for male and female patients aged 60 and over from the results of analyzing improvement strategies for inconvenience due to wearing alopecia wigs. When the patoent started perceive their depilatory diseases was right after treatment of anticancer drugs or radiotherapy, and they were found to suffer from inconveniences of being dried, etc. After treatment of chemotherapy, as for the falling-out parts, eyebrows were found to be the highest 52.1%, and pubic hair 38%, axilla hair 29% in that order. And the inconvenience level of wearing wigs among the patients with the different background of education indicates that the professions of the patients affect the ease of use. It is presumed that the easiness in use which the college graduates, high school graduates, and postgraduates showed is attributable to the age difference. to improve the inconveniences from cancer patients wearing wigs, scape troubles and close adhesion are constantly needed.

The aim of this study was to investigate the effect of charge carrier lipid on the skin penetration, retention, and hair growth of topically applied finasteride-containing liposomes. Finasteride-containing liposomes were prepared by traditional thin film hydration method using Phospholipon$^{(R)}$ 85 G and cholesterol with or without charge carrier lipid (1,2 dimyristoyl-sn-glycero-3-phosphate or 1,2-dioleoyl-trimethylammonium-propane for anionic and cationic charge, respectively). Freshly prepared finasteride-containing liposome suspension was applied on the hairless mouse skin, and skin penetration and retention were measured using Keshary-Chien diffusion cell. Non-liposomal formulation (ethanol 10% solution containing 0.5 mg/ml of FNS) was also used as a control. The amount of finasteride in the diffusion cell and mouse skin was measured by HPLC. The hair growth was evaluated using depilated male C57BL/6N mice. Mean particle size of all finasteride-containing liposomes was less than a micron, and polydispersity index revealed size homogeneity. Skin penetration and retention studies showed that significantly less amount of finasteride was penetrated when applied as anionic liposome while more amount of the drug was retained. Specifically, in liposome prepared with 10% anionic charge carrier lipid, penetration was 12.99 ${\mu}g/cm^2$ while retention was 79.23 ${\mu}g/cm^2$ after 24 h of application. In hair growth study, finasteride-containing anionic liposomes showed moderate efficacy, but the efficacy was not found when applied as cationic liposomes. In conclusion, topical application of finasteride using anionic liposome formulation appears to be useful option for the treatment of androgenetic alopecia to avoid systemic side effects of the drug.

Polycystic Ovarian Syndrome (PCOS) has now become more common in occurrence in women of reproductive age, particularly in urban and semi-urban population in India. So there is a need to investigate this phenomenon taking into consideration various aspects including possible treatment method to ameliorate/eradicate this syndrome, which has far reaching socio-economic impact and consequences, in view of infertility and irregular menstrual cycles frequently associated with this syndrome. Homeopathy is a branch of traditional alternative medicine which is gaining popularity in India and some other developing countries, as also in some of the developed countries in Europe. With this background scenario, we have made an attempt to treat cases of confirmed PCOS and tried to compare the relative efficacy of two potentized homeopathic drugs, namely, Lycopodium clavatum (Lyco) and Calcarea carbonica (Calc), most frequently used by homeopathic practitioners, selecting different potencies of the drugs, depending on condition/guiding symptom(s) of the patients. While the main focus was pointed on total/partial removal of cysts, data pertaining to different PCOS associated symptoms were also compared for the sake of learning if the two drugs had differential effects on these symptoms also. The study parameters in this investigation included: regularity/irregularity of menstrual cycle, presence/absence of acne, hirsutism, male type alopecia, acanthosis nigricans, body/mass index (BMI) and waist-hip ratio. Overall results provided clear evidences that both these homeopathic drugs had great ameliorating effects on PCOS, although each drug had a little different effect in respect of the individual parameters of this study.

Micro needle roller therapy has been used for cosmetic purposes, such as reducing skin winkles and improving elasticity of skin. It is claimed that micro needle roller therapy has potentials for connective tissue regeneration by facilitating collagen synthesis. Therefore, there seems to be a possibility that connective tissue regenerating potential of micro needle roller therapy could influence the hair growth cycle. This study, we investigated the hair growth-promoting effects of micro needle roller therapy. C57BL/6 mice were devided into three groups as follows: normal saline-treated, minoxidil-treated, and micro needle roller therapy-received group. Hair growth activity was evaluated by handscopic and microscopic observations. Sections of dorsal skin were stained with hematoxylin and eosin. Expression of BrdU, FGF, and VEGF was detected by immunohistochemical staining. Micro needle roller therapy enhanced the development of hair follicle during anagen. Immunohistochemical analysis revealed that micro neeld roller therapy incresed the expression of BrdU and FGF in the hair follicles of C57BL/6 mice. Furthermore, micro needle roller therapy upregulated mRNA expression of VEGFR-2, FGF-2, EGF - growth factors that play a central role in hair follicle development during anagen. These results suggest that Micro needle roller therapy can potentially be used for the treatment of alopecia.

This study was conducted to evaluate the effect of Grateloupia elliptica, a seaweed native to Jeju Island, Korea, on the prevention of hair loss. When immortalized rat vibrissa dermal papilla cells were treated with extract of G. elliptica, the proliferation of dermal papilla cells significantly increased. In addition, the G. elliptica extract significantly inhibited the activity of $5{\alpha}$-reductase, which converts testosterone to dihydrotestosterone (DHT), a main cause of androgenetic alopecia. On the other hand, the G. elliptica extract promoted $PGE_2$ production in HaCaT cells in a dose-dependent manner. The G. elliptica extract exhibited particularly high inhibitory effect on LPS-stimulated IL-12, IL-6, and TNF-${\alpha}$ production in lipopolysaccharide (LPS)-stimulated bone marrow-derived dendritic cells. The G. elliptica extract also showed inhibitory activity against Pityrosporum ovale, a main cause of dandruff. These results suggest that G. elliptica extract has the potential to treat alopecia via the proliferation of dermal papilla, $5{\alpha}$-reductase inhibition, increase of $PGE_2$ production, decrease of LPS-stimulated pro-inflammatory cytokines and inhibitory activity against Pityrosporum ovale.

Emodin is an anthraquinone derivative from the roots of Rheum officinale Baill that possesses a variety of biological activities, including inhibition of $5{\alpha}$-reductase and prostaglandin D2. In this study, we investigated whether emodin promotes hair growth. After emodin was topically applied to the shaved dorsal skin of telogenic C57BL/6 N mice, the hair growth rate and morphological analysis were evaluated in dorsal skin for 15 days. After 13 days of treatment, minoxidil or emodin (0.01% or 0.1%)-treated groups showed remarkable regrowth of hairs relative to the vehicle control group. Scoring of the hair growth and rate of hair growth area for 15 days revealed that groups treated with minoxidil and 0.1% emodin were significantly higher than the vehicle control group. Histological examination revealed the emodin and minoxidil groups markedly recovered the number and morphology of hair follicles, including the subcutis depth, relative to the vehicle group. These results suggest that emodin has an excellent promoting effect in hair growth similar to that of minoxidil and might be useful for treatment of baldness or alopecia.

Objective : Present study was carried out to investigate the effect of Gyungohkgo-gamibang extract on hair growth and protein expression in an alopecia model of C57BL/6 mice. Methods : Mice were divided into 3 experimental groups including normal (vehicle), Gyungohkgo-gamibang extract (YNS-10) and 5% minoxidil-treated group. The test materials were daily applied with 0.1 ml per mouse on shaved dorsal skin for 3 weeks. The hair growth was monitored by photograph at 5, 10, 15, 21 days after topical application. Then the changes of hair density and hair thickness in the hair-removed area were evaluated by phototrichogram using folliscope. Also the expression level of growth factors related to hair growth was measured by western blotting. Results : Application of minoxidil or YNS-10 stimulated the hair growth compared to vehicle treatment. Therefore hair density of minoxidil or YNS-10 application was increased about 200% and 210% more than in vehicle application on 14 day, respectively. And hair thickness of both minoxidil group and YNS-10 group was increased about 220% and 210 % more than in vehicle spreading on 14 day, respectively. Futhermore the protein expression of IGF-1 and VEGF were significantly up-regulated on 7 day in YNS-10 and minoxidil-spreaded group compared to vehicle-applied group. Conclusion : These data suggest that YNS-10 has potent stimulating activity on hair growth in C57BL/6 mice and potential usefulness as ingredients of hair tonic and hairrestore.

This study was conducted to evaluate the effects of Dictyota coriacea extract and its active components such as 1,9-dihydroxycrenulide and epiloliolide on the hair growth. Treatment with D. coriacea extract and the hexane and EtOAc fractions of D. coriacea extract significantly increased the proliferation of dermal papilla cells (DPCs), a central regulator of the hair cycle. Especially, 1,9-dihydroxycrenulide and epiloliolide from D. coriacea extract, caused an increase in the DPC proliferation. When isolated rat vibrissa follicles were treated with 1,9-dihydroxycrenulide or epiloliolide for 21 d, the hair-fiber lengths for the vibrissa follicles increased. When examined the activity of 5α-reductase, which converts testosterone to dihydrotestosterone (DHT), a main cause of androgenetic alopecia, the several solvent fractions of D. coriacea extract significantly decreased the 5α-reductase activity while 1,9-dihydroxycrenulide and epiloliolide scarcely inhibited 5α-reductase activity. In addition, we found that the D. coriacea extract and several solvent fractions of D. coriacea extract could not act as a K_ATP channel opener, which could be a contributory factor in the effect on hair growth. These results suggest that D. coriacea extract and 1,9-dihydroxycrenulide and epiloliolide, principals of D. coriacea, have the potential to treat alopecia via the proliferation of DPCs.
