    I moved to San Diego and needed a new look so I decided for extensions. I found Theory Hair Studio through Yelp and got connected with Uyen and Mary and have been getting my extensions installed and adjusted here.My hair is wavy and has multiple colors and faded dye and Uyen was able to match my hair color and texture exactly so that the blend of my hair is seamless. I get compliments on my hair all the time!Everyone is so nice and coming here to get my hair done is so much fun! You feel welcomed and included.

    Aidé , you are the best, thanks again for the awesome haircut! To whomever is reading, I highly recommend Aidé , she gave me the most beautiful cut (textured bob) last week which other stylists in the past at other salons have struggled to get right, but Aidé got it down perfectly and with effortless ease, all while being friendly and well just fun!Theory Hair Studio and Aidé thanks again, you guys are the BEST!!-Kat Young

    I have been saved by Uyen twice now! The first time around my hair was very over processed and she gave me the most perfect blonde and got my hair healthy again. The second time I had extensions done at the salon at the fashion valley mall and after a few weeks they were already slipping! They were extremely poorly done and Uyen had to completely remove them and do the job again. Now my extensions are seamless, well blended, and look amazing. Uyen has an impeccable technique and always does what’s best for my hair. Absolutely love my hair every time I come here. 10/10 recommend Theory Hair Services: Hair coloring
