If you’ve thought about esoteric salon services, rest assured that stylish Violet Hour has thought of them first. Yes, there’s the (nearly obligatory for Vegas) airbrush tanning and waxing services, but you can also get an incredible scalp massage at one of their massaging shampoo bowl chairs, or get some eco-conscious, vegan Spa Ritual nail care. Great hair treatments include Shu Uemura and Keratin Complex, and of course there’s a full range of makeup applications. (And, really, don’t forget your lashes. This is Vegas.) Call the spa to arrange in-room services if you don’t feel like making the pre-makeover journey through the hotel.
