    Uyen is fantastic! Not only brilliant with anything you need to make your hair look absolutely stunning, but also a genuine & caring person! I have fun catching up with her & look forward to my appts!
    I thought I submitted this review a month ago, but apparently I did not hit “post”… she was gracious about that too 😆.
    Adore her and you could not find anyone better to trust with your hair…

    Had one of the best hand tied hair extension installations here! They put hair on both sides of the head so that the beads aren’t visible and I’m obsessed— I would 100% recommend Theory!

    Uyen was amazing!!! I am obsessed with my hair! She worked so hard on my hair and took her time with the layers. I was nervous to go lighter and Uyen made me feel so much better about it and copied my reference photo beautifully. She did my money pieces perfectly, something I’ve never done before and will be coming back to get done again! Uygen made the hair coloring fly by with her amazing hospitality and conversation. I will definitely be coming back! You’re missing out if you don’t come get your highlights by Uygen.

    Requested style: Highlights and bright front pieces!

    Stylist: Uygen the best :)))
