This article explores the question of whether Japanese people wash their hair every day. It is generally true that most Japanese people do, due to having straight and thin hair which tends to become greasy quickly, as well as product build-up from styling products. The frequency of washing depends on individual preference and lifestyle factors. Benefits of daily washing include a healthy scalp, improved blood circulation and shiny hair. Common products used to wash hair in Japan are shampoos, conditioners and special treatments such as deep-cleansing masks or scalp tonics. Different methods used include lukewarm water followed by shampooing twice before a cold rinse, then conditioning if necessary before drying gently with a towel. Common mistakes made when washing hair include using hot water instead of lukewarm and forgetting to condition after shampooing.
