Seamless Hair Extensions in NYC - Volume and Length Extensions Luxury Salon

Our Mission

Where NYC’s brunettes, coppers, redheads and blondes come to get hair that looks expensive — and stays that way.

Kasthetix Beauty Salon is a private, luxury salon in Midtown Manhattan specializing in hair color and extensions — dimensional brunettes, natural coppers, rich reds, bright blondes and seamless extensions. Every service is fully customized to your hair, your lifestyle, and your goals.

Great color isn’t just about how you look leaving the salon. It’s about how your hair looks two weeks later, six weeks later, and when it grows out. That standard is built into every appointment at Kasthetix Beauty. 

 

Cassandra, the founder of Kasthetix Beauty Salon, started with a demanding NYC apprenticeship, was promoted on the floor, but decided to venture off and start her own independent artist business. This later grew into a private studio salon built entirely around one thing — exceptional results for clients who expect nothing less.

 

Private studio. One on one appointments. No rushing. By appointment only.
