Abstract
Shampooing is one of the indispensable and attractive services in barbershops and beauty salons. Hairdressers have to repeat shampooing over and over every day, and shampooing often causes a burden to hairdressers. Therefore, we developed a new shampoo technique which is characterized by moving the fingers in a kneading motion, and is different from the conventional shampoo technique that moves the fingers in a scrubbing motion. The purpose of this study was to assess effects of both the kneading shampoo technique and the scrubbing shampoo technique with various psychological and physiological indices of the practitioners and the recipients. In this study, an experiment for shampoo practitioners and an experiment for shampoo recipients were conducted separately. As a result, for the shampoo practitioners, the scrubbing shampoo technique increased a feeling of fatigue with Visual Analogue Scale (VAS), brachioradialis muscle stiffness, heart rate, and skin surface temperatures of forehead and tip of nose, but no significant difference was observed in the kneading shampoo technique. For the shampoo recipients, the kneading shampoo technique showed an increase in the salivary secretory immunoglobulin A (sIgA) level, and decreases in systolic blood pressure and pulse rate. These results suggested that the kneading shampoo technique is very useful, because it could reduce the burden for practitioners and also improve the comfort for recipients. Thus, our study would contribute to improvements in hairdressers' working environment by reducing the burden of shampooing, and in the quality of their services by providing more comfortable feelings to shampoo recipients.
