Various commercial shampoos were frequently prescribed for dermatologic therapy in small animal practice. Skim hydration affected by the shampoos, however, was not evaluated routinely. In order to evaluate the skin hydration for the exact prescription of shampoos method to measure skin hydration of shampoos are needed. This study was undertaken to evaluate the skin hydration effect of shampoo on canine skin using Corneometer. Five healthy dogs were applied with 7 commercial shampoos: Humilac, Sebocalm, Sebolytics, Etiderm, Benzoyl peroxide, HyLyt and Zn-7 Derm. Skin hydrations were evaluated by measurement of electrical capacitance by Corneometer. A statistically significant increase in skim hydration was found 17(p<0.05) and 77 minutes(p<0.01) after application of Humilac indicating a humidifying effect of this product. A statistically significant decrease in skin hydration was found for the Benzoyl peroxide after 77 minutes(p<0.05). No statistically significant differences between the other shampoos were found. None of the products tested had any negative effect on the skin barrier function. The Corneometer was found useful for detecting skin hydration to shampoos and considered as a simple and useful tool for prescription of various shampoos routine practice.

This study surveyed 150 men aged 30 to 50, a demographic which seborrheic dermatitis is common. The time of day one shampoos and recurrent fatigue were found to have a statistically significant impact on symptoms contributing to the main causes of seborrhea, including itchiness, excessive oil, acne, and redness on the scalp (p<0.01). Study results confirm lifestyle and shampoo habits, such as the frequent sense of fatigue, a routine work schedule, susceptibility to stress, the time of day one uses shampoo, and whether hair styling products are used, affects seborrheic scalp disease. This study found seborrheic scalp disease for office workers primarily resulted from shampoo habits, rashes were predominantly caused by a failure to rinse shampoo and dry hair completely, while secondary aggravating factors included irregular work schedules, recurrent tiredness, and chronic stress.

Ethanol-based dry shampoo may provide an important and valuable resource in convenience for patients and busy people due to the unnecessity of water to wash out. In this research, ethanol-based dry shampoo was prepared by simple mixing of specific detergent materials and different contents of ethanol. Cytotoxicity was examined by the MTT assay to determine less-irritative materials of detergent and shampoo. Patch test on skin was performed to figure out the degree of skin irritation and also antimicrobial effect was examined by the eradication of bacteria. As a result, it was confirmed that ethanol-based dry shampoo had non-cytotoxicity as well as an antibiotic effect. Therefore, ethanol-based dry shampoo will be able to provide esthetic and hygienic hair treatment purposes with cleanliness and convenience.

This study conducted a 4-week clinical trial on 30 males suffering from seborrheic dermatitis and hair loss symptoms to examine the effects of rooibos extract on the seborrheic dermatitis improvement of 30-50 year old middle aged males. The comparison group used shampoo with no rooibos extract while experiment group 1 used shampoo including rooibos extracts, and experiment group 2 used shampoo and scalp enhancer including the rooibos extracts. The results showed that there were no meaningful changes on the scalps of the comparison group while experiment group 2, which used both shampoo and scalp enhancer including rooibos, showed better improvement on seborrheic dermatitis than experiment group 1 which only used shampoo including rooibos. These results imply that shampoo and scalp enhancer including rooibos extracts effectively improve the oil-moisture balance on seborrheic dermatitis and effectively deals with scalp itchiness redness and the color tone of the scalp, suggesting its use in scalp cosmetics that include antioxidation activation elements, which are effective in improving seborrheic dermatitis.

In this study, we prepared the functionalized Shampoo with three-type functionalized microcaples which were synthesized by microcapsulation, respectively. In detail, the functionalized microcapsule was included such as (1) the functionalized microcapsule with core-menthol and shell-melamine resin and (2) the functionalized microcapsule with core-menthol and shell-lecithin, and (3) the functionalized microcapsule with core-cinnamon oil and shell-lecithin, respectively. The size and morphology of the prepared microcapsules was evaluated via Optical Microscopy (OM), Scanning Electron Microscopy (SEM) and Dynamic Light Scattering (DLS). From these results, the prepared microcapsules with size of 0.1~0.2 ㎛ and spherical morphology was confirmed. Furthermore, we applied the prepared Shampoo to treat hair. As results we confirmed that the scalp temperature was decreased about 3~4 ℃ compared to no treatment. This result may be considered that the core compounds are vaporize when the functionalized Shampoo is treated on scalp. We will determine the change of scalp pore, diameter of hair, and etc during treatment of the functionalized Shampoo.

In this research, botanical extracts containing green tea, Saururus chinensis and Prunus padus were tested to see possibility as shampoo. Leaves of Green tea and Saururus chinensis were extracted with hot water. Prunus padus bark extract was applied reverse osmosis and ultrasonic extraction. When interfacial tension was measured among shampoo including botanical extracts, Sodium dodecylsulfate(SDS) and Quillaja Bark Saponin(QBS), that of shampoo was lower than that of SDS and QBS at lower concentration, however, it showed similar interfacial tension at 100% concentration. Shampoo showed moderate antimicrobial activity in Staphylococcus aureus and Candida albicans. Botanical extract did not indicate cell toxicity up to $350{\mu}g/ml$ concentration in MTT assay. Shampoo containing botanical extract was stable for 3 months, however, it showed considerable variation in pH and viscosity. In conclusion, shampoo containing botanical extract shows strong possibility for natural shampoo if the formulation is modified.

Shampoos are used routinely by a large number of veterinarians to treat skin diseases. Skin pH is affected by shampoos, however, known to occur. In order to evaluate the effect of shampoos on skin surface pH, we performed the measurement of skin pH using skin pH meter PH900 in five healthy mixed breed dogs. The seven commercial shampoos: Humilac, Sebocalm, Sebolytics, Etiderm, PEroxyderm, HyLyt and Zn-7 Derm were included in this study. The anatomical sites, right thorax was the highest pH (7.66$\pm$0.10), and the lowest pH (6.20$\pm$0.23) was left pinna. A statiscally significant decrease in skin pH was found 7 minutes after application of Humilac, Sebocalm, Etiderm, Peroxyderm (p<0.01) and Sebolytics (p<0.05). After 17 minutes of application skin surface pH was inclined to increase in every shampoos but the degree of increase was slight at 77 minutes. No statiscally significant differences were found in HyLy-T and Zn-7 Derm, but skin pH was normal range (6.2-7.8) after application. Throughout the experiment skin surface pH was maintained above pH 7.0 in detergent. The commercial shampoos, Humilac, Sebocalm, Etiderm, had the decreasing effect on skin surface pH in dogs. The other four shampoos maintain the skin pH normal range. The skin pH meter PH 900 was found simple and useful for skin pH measurement.

Various commercial shampoos were frequently prescribed for dermatologicstherapy in small animal practice. Skin surface sebum affected by the shampoos, however, was not evaluated routinely. In order to evaluate the skin surface sebum for the exact prescription of shampoos methods to measure skin surface sebum of shampoos are needed. This study was undertaken to evaluate the skin surface sebum effect of shampoo on canine skin using sebometry. Five healthy dogs were applied with 3 commercial shampoos: Sebocalm, Sebolytics, and Benzoyl peroxide. Sebocalm had a great effect on skin surface seoum and normal saline also affected the skin sebum. Sebolytics and benzoyl peroxide had a moderate effect of skin sebum. The lowest effect was shown in detergent. Therefore, Sebumeter was considered a good and convenient apparatus for skin sebum measurement in order to evaluate the effect of shampoos on skin sebum. None of the products tested had any negative effect on the skin barrier function.
