$29 for an At-Home Teeth-Whitening Kit ($158 Value)
Clients sink teeth into trays twice a day for 30–60 minutes, depending on tooth tolerance. While the peroxide gel does its whitening work, clients are free to watch TV, read a book, or complete a triathlon. The kit supplies enough gel for seven to nine sessions.
