Katy O’Sullivan

Katy was amazing! So thorough and got my vision. Lovely spending time beautifying with her

Katy is phenomenal!! I have very dry, curly, thick hair that at its color baseline, is what my mom fondly refers to as "dishwater-colored." I came to katy after not getting it colored for awhile, and she made it so much brighter and more dimensional. She is lovely to chat with and so, so talented!!

Really love Katy’s work - honestly one of the best colors I’ve ever had. She pays so much attention to detail in her technique and made sure to understand exactly what I wanted before getting started. So happy to have found her!!

Katy was great! She brought my hair back to life and I’m loving the cut she gave me. She was honest with the questions I had and would definitely recommend her
