Instead of taking a group to a spa, why not have the spa come to you? These services allow event hosts to bring technicians to hotels, meeting rooms, and event spaces and treat guests to services from meditation instruction to straight-razor shaves.

Billed as an "on-demand beauty service," Stylisted is an online platform that lets users or event hosts book on-location hairstyling or makeup services including airbrushing and lash application.

Zeel, a service that dispatches massage therapists, sends staffers to meetings and events in the New York metro area, South Florida, the San Francisco Bay area and Silicon Valley, and Southern California. (Soon, the service will be available in San Diego and Las Vegas.) Massage therapists arrive at venues with their own massage tables and can perform services such as Swedish or deep-tissue massages for 60, 75, or 90 minutes. For meeting breaks, therapists can give 10- to 15-minute chair massages. The services can be booked 30 days in advance.

Soothe is another on-demand beauty service that can be booked for meetings or private events in cities including Los Angeles, Miami, Phoenix, and Austin, Texas. This spring, the service will launch in San Francisco, Washington, Chicago, and New York. Individuals can use the service to book 60- to 120-minute massages at hotels or offices, while chair massages are available for groups. Bookings can be made online or via phone.

Priv, a beauty and wellness app, lets users book appointments for services such as blowouts, manicures, men's straight-razor shaves, and spray tanning. Staffers can travel to meetings and event spaces in New York, Southern California, and London. Company reps work with event hosts to determine the number of spa technicians needed at an event and can also arrange for kid-friendly services such as face painting and braid bars.

The mobile spa At Your Service travels to events and meetings throughout greater Toronto and specializes in providing services at fashion shows, media events, corporate gatherings, and spa parties.
