Tax salon services

Currently all salon services in the state of Washington are tax free. No sales tax, no luxury tax. Most of these services including haircare, nails, facials, massages etc. are services the well off indulge in. The state has continually used the "sin" tax to raise money by taxing beer and cigarettes (now weed too)...but, has never approched taxing the rich for their pampering in the salon. It would raise desperately needed money for the state and not effect the lower class.
