When Tye Bogle was an undergrad at Hofstra University, she spent a lot of her free time in the dorms doing her friends' hair. Soon, her love of styling had eclipsed her plan to go on to law school—she enrolled in cosmetology school instead. The decision proved a wise one. Today, Tye owns SalonTaj, a multicultural beauty destination where clients can request services from dreadlocks to single-process color treatments.
Tye's specialty, however, is extensions. She meticulously applies Brazilian extensions strand by strand, and shows clients how to add or remove clip-in pieces for when their coworkers call them a beautiful imposter. All of her extensions are made from 100% human hair, and as a result, her finished looks are as natural as they are flattering.
