Spas are seeing a growing number of time-poor clients who are eager to de-stress and detox -- but in a rush to get that job done. Experts say the key for spas and salons is to offer lower-priced experiences that can be had in shorter time. "A lot of our express treatments are very value-oriented," said Jo Harris, the brand's head of beauty at Urban Retreat Spa at Harrods in the UK. "We use things like hot mitts and lavender pillows, or we might give an eye treatment while we're doing a foot massage. There's a lot going on in the shorter treatments to add value."
