Volume of turnover in hairdressers and beauticians branch

This is spending in hairdressers and beauty parlours, after correction for price changes. This spending depends on the frequency of visits and what customers have done during these visits. The volume of visits may decrease, because for example customers go to a hairdresser less often, or because they have less done when they do go there (e.g. only a haircut, instead of having their hair washed, cut and dried).
