In this study, it is intended to provide basic research data on hair loss and problematic scalp that is expanding to lower age groups and women. When using Company B's hair ampoule containing L-Menthol, Salicylic acid, and Dexpanthenol daily for women in their 20s with problematic scalp, the effect on the scalp and hair after 4 weeks was investigated. As a result of this study, when using Company B's ampoule containing L-Menthol, Salicylic acid, and Dexpanthenol, the subjects showed improvement effects such as relieving inflammation, reducing scalp fever and erythema, reducing itching and hair loss, and increasing hair thickness. In addition, it was confirmed that the scalp self-diagnosis of the subjects showed improvement effects on scalp satisfaction, scalp vitality and elasticity, heat generation, scalp pulling after cleaning, and itching. Through these research results, it is believed that products containing L-Menthol, Salicylic acid, and Dexpanthenol will help improve problematic scalp and hair.

The hair nourisher products are used for prevention of hair loss and classified as quasi-drug in Korea. As concerns about hair loss has been increased, the demand for hair nourisher products has been growing. It is difficult to analyze their main ingredients because they contain various ingredients including natural plant extracts, vitamins, preservatives and exfoliators. The purpose of this study was to develop and validate simultaneous analytical methods of active ingredients in hair nourisher products such as nicotinamide, tocopherol, salicylic acid, dexpanthenol and benzyl nicotinate by HPLC. The active ingredients were separated on a $C_{18}$ column by using acetonitrile/phosphate buffer as a mobile phase, and detected at UV 220, 270 and 300 nm. The calibration curve showed linearity in the range of $12.5{\sim}800\;{\mu}g/mL$ and the recoveries were 97.3 ~ 103.5 % (RSD 0.9 ~ 2.8 %) in liquid matrix and 101.9 ~ 115.9 % (RSD 0.7 ~ 7.7 %) in shampoo matrix. Validated method was applied to hair nourisher products obtained from distribution market. Fortunately, all samples met their criteria. This study might be expected to provide the method for determining active ingredients in hair nourisher products and lead to promote a rapid market entry.
