***I highly recommend you take this review seriously and go somewhere else*** I had my hair cut 4 inches shorter than I asked for so I went to this salon because of the pretty Instagram pictures and good reviews, and the desire to finally try extensions while I waited for my hair to regrow. At first everything seemed ok, but it really went downhill. The extensions were pretty and matched my hair color quite well, and the styling was good on the day of install. However, no trimming was done to the extensions to help them blend with my hair more, so the shelf was obvious at home. I enjoyed the energy in the salon at the time with good girl talk. Shortly before I went back for the first move up appointment, Uyen called me and said I had too much of a shelf and that we should add another ro

I just arrived in San Diego 4days ago and found this studio on google. Literally could not have made a better decision. My cut is gorgeous. I got layers in the back amd the front. And I feel like a brand new woman ready to take on this city!!! So happy with my new haircut!!

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.

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…
