Meet the Founder

My name is Kayla Alonso, and I’m the founder of BrowDefinedXO 

This journey started from a place of insecurity— I grew up struggling with my brows and began filling them in at just 11 years old. When I got my brows permanently done at 19, the confidence it gave me changed everything and inspired me to help others feel that same way.


Over the past few years, I’ve specialized in brow laminations, shaping, and tinting — and have had the honor of training over 80 students across the U.S.

From working behind a curtain in my bedroom to now being in my own private suite — BrowDefinedXO was built with passion, purpose, and love. 💌
