Eyelashes may not be as diverse as fingerprints, but licensed aesthetician Reagan is trying to fix that. She applies extensions in eight lengths and three thicknesses, customizing sets to suit the style of each client. This variety allows her to create looks that range from subtle curls to diva-esque swoops. During appointments, she uses a specialized adhesive to meticulously place extensions onto individual lashes. The extensions are synthetic and hypoallergenic, and last for up to six weeks with the help of fills or touchups. Though applying these extensions is her main service, Reagan also waxes brows, lips, and chins from her salon suite.
