Background: Scalp seborrheic dermatitis is a common disease characterized by flaking and itching of the scalp. Conventional treatment options, such as the use of topical corticosteroids and antifungal agents, may cause adverse effects and reduce user satisfaction rates; thus, it is important to explore other treatment options for scalp seborrheic dermatitis. Objective: We aimed to evaluate the efficacy and safety of a new-formula shampoo containing natural ingredients, including the extract of Rosa centifolia petals, epigallocatechin gallate, zinc pyrithione, and climbazole. Methods: A total of 50 patients with scalp seborrheic dermatitis were enrolled and divided into two groups: the new-formula shampoo-treated group and the 1.5% ciclopirox olamine shampoo-treated group. Clinical severity scores, sebum secretion, and inflammatory cytokines were assessed. In addition, patient satisfaction and adverse events were assessed using a questionnaire. Results: The new-formula shampoo was comparable with ciclopirox in reducing the clinical severity scores and sebum secretion. Patients' improvement scores and user satisfaction rates were higher in the new-formula shampoo group than in the 1.5% ciclopirox olamine shampoo-treated group. The inflammatory cytokine levels considerably changed in both groups during the course of the study. Conclusion: Thus, the new-formula shampoo can be considered a treatment option for patients with scalp seborrheic dermatitis.

Omega-3 fatty acids are a specific type of unsaturated fat that the body cannot manufacture on its own, so they must be obtained from food which is essential fatty acids (EFAs). Omega-3 fatty acids consist of three types which are a-Linolenic Acid (ALA), Eicosapentaenoic (ELA), and Docosahexaenoic Acid (DHA). Especially, EFAs help to prevent skin and hair drying, acne, eczema, prevention from allergies, brittle nails, rashes, and tiny lumps. The aim of this study is to investigate improvement and protection for hair damaged by chemical treatment with omega-3 formulated shampoo. We selected virgin hair sample and divided into two groups for bleaching once and three times and then damaged hair by changing the number of hair bleaching (twice with interval of 15 minutes). Each bleached hair was treated by five different kinds of shampoo (Control, Horse shampoo, DHA shampoo, EPA shampoo, Omega-3 shampoo mixture). Apart from this, EPA/DHA 2, 5, 8, 10 and 12% shampoo were prepared and treated to hair for comparing rate of progress in damaged hair. To quantify improved condition of damaged hair, we performed Scanning Electron Microscope (SEM) for ultrastructure of damaged hair fraction, measurement of thickness change and BCA Protein Assay for recovery rate of damaged hair. The moisture in hair was measured by Thermal analysis machine. In results, we observed the particle of hair surface damaged by bleaching treatment were well improved with treatment with EPA and DHA shampoo. Also, quantity of protein was lowered with higher concentration of EPA & DHA i.e., 8 and 12 % then compared with horse oil shampoo in three times treatment group. It shows that bleached hair have been recovered by treating rapidly and get protective coat. In conclusion, EPA and DHA shampoo improved damaged hair, especially with EPA / DHA 12% shampoo. Also, EPA shampoo could protect the damaged hair depending on increasing concentration of EPA. Therefore, we conclude omega-3 shampoo could make damaged hair protect and get healthy hair environment.

The purpose of this study was to determine the effect of IPBC(3-lodo-2-propynylbutylcarbamate) on dandruff caused by the anthropophilic fungus Malassezia furfur. The effects of IPBC on dandruff were examined by evaluating (a) the MIC value of IPBC using broth dilution method; (b) the remnant antimicrobial activity of IPBC containing shampoo on skin disc; (c) the antidandruff efficacy of 1.0 % IPBC containing shampoo in double blind clinical trial. To investigate the remnant antimicrobial activity of IPBC against Malassezia furfur, guinea pig-skin disc was washed with antidandruff shampoo and then the diameter of inhibition zone per disc was measured. For clinical trial, thirty healthy volunteers, aged 25-35, participated in 4 week study. At 0, 2, 4 weeks, examinations of scaling, itching on scalp were carried out. The MIC(Minimun Inhibition Concentration) values of IPBC range from 0.10 to 1.00${\mu}g/ml$ and it seems that IPBC is more effective in the MIC values than zinc pyrithione, selenium disulphide, piroctone olamine and comparable to ketoconazole, climbazole. When the remnant antimicrobial activity of IPBC shampoo on skin disc was determined, 0.5% IPBC shampoo and 2.0% Ketoconazole shampoo resulted in similar antimicrobial effect. In addition, 1.0%, 2.0% IPBC shampoo was more effective than 2.0% ketoconazole shampoo. After two and four-weeks of 1.0% IPBC shampoo treatment, there was significant reduction of scaling, itching in test group compared to control group. On the basis of these results, it can be concluded that 1.0% IPBC is more effective than 2.0% Ketoconazole in reducing dandruff. It seems that strong capacity of drug binding to the stratum corneum plays a role in its antidandruff effect since adsorption of active ingredients on scalp is very important factor in reducing dandruff.

Bonogen shampoo is composed of several plant extracts which are known to be used in oriental medicine. This study was carried out to investigate the effects of Bonogen shampoo on hair growth in an alopecia model of C57BL/6 mice. There were eight male and female experimental groups including distilled water(DW: negative control), a commercial shampoo[M], 3% minoxidil (MXD) and Bonogen shampoo(BNG). Dorsal skin hair of six-week-old mice was trimmed with an electric clipper carefully not to damage the skin. The next day, mice without skin scratch were selected, randomized and separated in 10 mice per group. The test compounds were topically treated with 0.15 ml per mouse or dorsal skin for 21 days daily and then washed thoroughly with DW. The hair regrowth was determined photographically at 0, 4, 7, 10, 15, 18, and 21 days and histologically at day 21. No clinical signs were observed in all mice. Although body weight was slightly increased in 3% MXD group than other groups, it was not significant. Hair regrowth began to be promoted after 14 days and appeared a distinct regrowth pattern in all animals by topical treatment of test compounds at 18 days. In particular, the topical treatment of bonogen shampoo or 3% MXD for 21 days to dorsal skin accelerated hair regrowth faster than DW or M shampoo. At 21 days, the hair regrowth promotion speed was in order of 3% MXD>BNG>M>DW. The bonogen shampoo or 3% MXD also promoted hair follicle elongation compared to the negative control. These results suggest that bonogen shampoo has hair growth promoting activities and may be useful for treatment of bald or alopecia.

Canine skin is a highly dynamic organ that is constantly adapted to changes in its environment. It provides structural, sensory, immunologic, and physiologic functions and contributes an essential barrier function against potential environmental insults. We assessed the changes of canine skin hydration, pH, and protein contents by noninvasive method according to the frequency of application with canine commercial shampoo. Canine commercial shampoo was applied topically every other day, 5 days, and 8 days on different sites, respectively in 8 dogs. Saline-applied site was as a control. Skin hydration was increased and skin surface pH was decreased significantly in canine commercial shampoo-applied site every other day (p < 0.05). Also, skin protein concentration measured by D-squame$^{(R)}$ tape stripping method was increased significantly in canine commercial shampoo-applied site every other day (p < 0.05). There were alterations on every 5 days and 8 days, but not significantly. These results may be recognized that the frequent use of canine commercial shampoo cause abnormalities of the skin barrier function and alteration of stratum corneum integrity/cohesion. Consequently it was suggested that bathing the dog with canine commercial shampoo was appropriate every 5 or 8 days.

Zinc pyrithione (ZnPT) is a coordination complex of zinc and has been used widely as an anti-dandruff agent in shampoos. Many shampoos contain both ZnPT and EDTA, a chelating agent speculated to increase ZnPT absorption, thereby raising concerns about neurotoxicity. Here, we investigated the effect of EDTA on ZnPT absorption by direct comparison of ZnPT and pyrithione (PT) concentrations in shampoo formulations, and by pharmacokinetic analysis of ZnPT, PT, and 2-methanesulfonylpyridine (MSP), the main ZnPT metabolite, in rat plasma or urine following exposure to shampoo containing ZnPT alone or a combination of ZnPT and EDTA. Approximately 17.3% of ZnPT was converted to PT by the addition of EDTA in the shampoo formulation. Plasma ZnPT and PT concentrations were not measured up to 24 hr after treatment with shampoo containing 1% ZnPT or 1% ZnPT + 2% EDTA in all rats. However, PT amount in 24-hr urine sample, MSP concentration in plasma, and MSP amount in 24-hr urine sample were approximately 4-, 2.6-, and 2.7-fold higher, respectively, in the 1% ZnPT + 2% EDTA shampoo group than in the 1% ZnPT shampoo group. As confirmed by the formulation analysis and in vivo pharmacokinetic analysis, the exposure of ZnPT could be increased by the absorption of PT due to partial dissociation of ZnPT into PT.
