Nicest shop owner ever!

This place is amazing, Uyen is the best!! Definitely recommend for highlights/blondes!

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!


Sep 05, 2024

Uyen is great! Love getting my extensions and color done here, perfect every time.


Aug 05, 2024

I have been going to Theory for 5 years and Uyen does an amazing job! I love how close it is to where I live in Little Italy. Uyen is amazingly professional and knows her stuff. I always walk out with fabulous color and feeling confident. If you are looking for hair color or extensions Theory is the place to go!

I have been going to theory hair studio for years and always does such a great job. I wouldn’t trust anyone else with my hair! The energy is always positive and fun.


Aug 05, 2024

Love this place and my hair extensions!


Aug 05, 2024

Uyen is the best in town for extensions! Before I was referred to her by one of her clients, I had hair extensions done elsewhere and they hurt my head. I had to take them off. I was hesitant to do them for years and then I came to and she is amazing. I’ve been with her now for over a year. Uyen is a true professional, super sweet, personable, and funny. I enjoy every visit with her and look forward to it. Highly recommended for extensions!


Aug 05, 2024

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 has the best attention to detail and incredible skill. Great vibe in her salon in Little Italy. Highly recommend.


Mar 05, 2024

Uyen truly blows my mind every time! (Before and after pics attached) Innately talented, strictly detailed and passionate about hair!!🙌🏼💕 I’m extremely picky with my hair and No One cuts and colors the way she does!! 14 yrs. and counting, so grateful our paths crossed and I always look forward to the next appt., you’re truly the BEST Uyen!! Thank you!!🙏🏼


Feb 05, 2024

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

Great service, very responsive personnel, but also very expensive.


Feb 05, 2024

I have been going to Theory for years, and I keep coming back because Uyen is incredible! I get extensions, and they are top of the line. I look forward to the appointments because she’s so much fun to talk with! Super highly recommended.


Feb 05, 2024

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.

I was looking forward to an Asian stylist but what a huge disappointment. I could not find anywhere to hang my coat and I totally forgot when I left it beside me. She was very rushed with serving 3 clients at the same time window. I wanted Carmel color and it turned out to be ash. Color was not discussed and shown to me. She spilled a lot of the dye mixture and one plopped on my navy jacket. My Hobbs London bought jacket was destroyed. I thought never mind did not want to pile up to her life problems that I heard while I was there, this is just a jacket. Cut wasn’t too bad but oh boy my my hair is so ash light. I understand she is trying to blend with some of my grey. But now I look like I have head of grey hair. On top of that my hair is totally fried. Split ends and frizzy. Paid $391 + $50 deposit for cut and bleached hair. So sad now trying to get treatment to revive my hair.


Feb 05, 2024

the BEST salon. uyen does the most incredible job, could not recommend a salon more than this gem! 10/10 every time!


Feb 05, 2023

I absolutely love this salon. Uyen is a hair genius! I wouldn’t go anywhere else. She has helped me build my hair confidence for the last 2 years and counting. 100000000/10!!!!!!


Feb 05, 2023

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🥰


Feb 05, 2023

I waited for a over a month for this appointment. Three hour appointment, I just got back from off roading in the desert so I said my hair is dirty. She wouldn't wash my hair and canceled the whole appointment. Was extremely rude.


Feb 05, 2023

I was really excited about this place but the owner isn’t nice and they never answer the phone. I would not recommend.


Feb 05, 2023

Love this place! Great service and they always leave my hair looking so good! Highly recommended if you do any color or extensions. Can’t go wrong!


Feb 05, 2023

THE place to go to for cut, color, hair and lash extensions. I’m so happy I found Uyen when I first moved to San Diego. She fixed my hair color and brought my hair back to life! I honestly don’t trust anyone else with my hair. I don’t live in California anymore but I make sure to book flights out to see her. She will really take the time to work with you to get the look you want. She is so great at what she does and has a real artist eye for hair. Like I said she’s the only one I go to, and you’ll feel the same way.


Feb 05, 2023

Very disappointed with the condition of my hair. After Laisa did full head highlights, I got home, I took a better look at natural light and my hair was in 2 shades: gray and yellow around roots and dirty dark on the length. It was just terrible looking. 2nd day I called and I went back and they used a bleach to wash the terrible color that cost me $500. I got home and after my first wash my hair is fully yellow. On top of that their attitude was awful. Never again there!


Feb 05, 2022

Being new to San Diego, I rely on reviews. All the glowing reviews for Theory Hair Studio were spot on! The studio is bright and clean, the staff is friendly, and my haircut was exactly what I was going for!


Feb 05, 2022

Jane did an incredible job with my Brazilian blowout. It was perfect. She did my color as well which was perfect! I would very highly recommended this salon.


Feb 05, 2022

Service was terrible gave us a 5 grand estimate for 24inch hair, told us we would trip on the size we wanted. Taking our money else where


Feb 05, 2022

So flaky and unorganized. I requested an appointment on Saturday and by Sunday I received a confirmation text for my appointment. The morning of my appointment the owner emailed me asking to reschedule for the following week. She went on to say that my appointment was never confirmed. I sent her screenshots of the confirmation text. I had scheduled my entire day around this appointment and tried calling 5 times over several hours and emailing her back without hearing whether or not my appointment was still on for the day. I would never recommend this salon to anyone who wants a reliable stylish. This was the owner BTW! How unprofessional.


Feb 05, 2022

The owner/stylist did a wonderful job for my boyfriend's mom who hadn't had her hair cut in years. She took her time and worked to frame her face perfectly! Loved it!


Feb 05, 2022

Uyen is an absolute ANGEL & hair goddess. She was able to accommodate my last minute scheduling & made my hair look fabulous. I can’t recommend enough, I’ve never had a hair stylist care so much! ❤️ Thanks for everything Uyen!


Feb 05, 2021

After almost a year of coming to Uyen I can honestly say that I don't think I'll ever be able to go to anyone else. Not only did she save my hair (seriously, saved it), she is so much fun to talk to. If you're going to be spending 3+ hours with someone during an appointment, you want to enjoy being around them! Uyen is the best!


Feb 05, 2021

I am in total shock. I had a very unexpected death in my family yesterday and I had to cancel my appointment. I received the reminder text and cancelled through the system. I completely forgot about this appointment while I'm matching arrangements, and grieving when someone called me from the studio. I was then told that I would bee charge half ($96) of the appointment even though I had attempted to cancel. When I asked her to please work with me through this very dark time, she hung up on me- charged me- and refused to pick up the phone. I'm already heartbroken and now in total shock that someone would treat another person grieving a loss this way. I wouldn't recommend going here to anyone- based on her unprofessional manner and money motivated behavior. Just wow.


Feb 05, 2021

I am so particular with my hair and I was so pleased with this salon. My color is perfect and she was so thorough. I will definitely be returning (:


Feb 05, 2021

My extensions look great and the staff is super sweet! Highly recommend.


Feb 05, 2021

Uyen is amazing! I am very picky and she does an amazing job with my hair extensions and listens to what I want and makes me feel comfortable. She is super friendly and so talented, I am so happy I found her. Highly recommended! She is a gem!


Feb 05, 2021

Uyen is seriously amazing! It was hands-down the best salon experience I've ever had. If you want long, luscious, mermaid hair- GO HERE!


Feb 05, 2020

Amazing!!! Always accommodating with my busy work schedule, works miracles with my delicate hair, and a beautiful studio.
