Rayhana is truly the color queen! I've been going to her for 4 years now, and every single time I leave her chair obsessed with my hair. I originally found her on Instagram because I was specifically searching for someone who specializes in dimensional brunette. So many stylists can do blondes, but not everyone really understands brunettes especially color correction. I came to her with permanent dark brown dye and asked for dimensional brown, and she absolutely worked her magic. My hair was lifting red in certain spots and she had to pull out all the stops, but she walked me through everything she was doing and explained the process the whole time. I felt so confident being in her hands. I get compliments on my hair all the time, and I'm always happy to tell people about her because she is THAT good and deserves all the recognition. Thank you, Ray. You have a forever client in me read more

I came in 7/24/25 to get a balayage by Rayhana. I came across her Instagram and decided this is where I want to get my hair done, their work looks incredible. I initially messaged Judy and waited over a week and nothing. So then I messaged Rayhana and she got back to me right away, even scheduled me in. I was beyond excited. I get to the salon and her assistant greeted me (not a smile) and stated Rayhana would be in shortly. I waited a bit and then Rayhana finally showed up but very unfriendly and dismissive. Not a smile either. Now, I don't expect people to always be smiling. But I am paying for your services, you being friendly is a part of the customer service you provide for your business. There wasn't even friendly convo. She was very serious and dry. She just asked about my hair history and what I wanted, that pretty much sums up all the convo we had. Maybe a few sentences here and there. Then a regular customer seemed to have walked in because her and her assistants demeanor changed to smiling and laughing and conversing with her. So it wasn't that they were in a bad mood or just having a bad morning. They were choosing who to be friendly/nice to. It also bothered me that her assistant did half my hair. I'm supposed to be paying more bc the owner Rayhana is doing my hair... so why is she having her assistant do most of her work. The assistant also washed my hair; toned it; and blow dryed it. When my hair was done, it was too blonde and then one side seemed to not match the other? And I told her and she had the nerve to say "i can't do it even/perfect. I am not a robot" she said "I am not a robot" about 3-5 times. I was beyond irritated. Plus she charged me $90 for a haircut. $90!! When she didn't spend more than 10 minutes cutting it. 5-10min cut. Outrageous. Never coming back here again. Poor service customer. Not friendly at all. They pick and choose. read more

I tried calling the salon to set up an appointment but no one answered so I inquired online and Danielle immediately contacted me. I'm not sure why Danielle contacted me via text versus another stylist but she did and she was kind and took me in the day after contacting me. She moved my appointment several times due to her forgetting she had a prior commitment which was fine with me and I was happy just to be seen so fast. I needed to be out by 2 since I had to work. I sent her what my hair looked like that same day she contacted me and I sent her an Inspo pic from the salon she works at. During the appointment she wanted to take pics for her content which I said yes to but I thought to myself... she knows I'm on a time crunch.. and this is cutting into my appointment time. The appointment was at 945 and I didn't have dye on my hair until 1015. That's 30 min. She did balayage on me. She checked the foils & said I needed a hair cut. I told her I didn't want one. She said too bad you're going to need it. I reminded her, I didn't not ask for one. She said whether you like it or not you need one etc. I asked her if my hair was broken due to the bleach and she said no, then quickly said well all hair breaks with bleach... right there and then I told her she didn't have to leave the foil on that long because I know my hair won't lift. She said she wanted to leave it on longer and wouldn't let me walk out like that because I was a representation of her work. I asked her why it was so light and orange and she said my root melt that we're going to do was going to fix that... It was obvious to me she over processed my hair and she kept pushing for a haircut because of her inexperience which resulted in my hair being fried I've decided to do my root melt and cover my grays the next day since it was getting late. I needed to go to work and she had another client that walked in for their appointment. She requested for me to pay her while she was still blowing my hair. She charges me 450$ and I left her a 20%tip. So I paid her 540. I did all of this while she was still blow drying my hair. She said I had to pay her upfront for the service before I left even through she wasn't finished covering my grays and doing a root melt. I've never had a stylist charge me for work they haven't even done. She should have charged me for the balayage then charged me for the rest the next day. I went to work and saw how bad my hair was. There was so much bleach on my hair when all I wanted was dark with dimension. My hair looked shorter, less volume and lighter. The breakage was evident. Next day: I asked her to tone my hair darker since it was too light. I asked for a 5 or 6 and she said it was too dark. I said I WANT IT DARK... I've been asking for dark brunette form the very begging. Anyway, as she was covering my grays I asked her if she could try not to get it on my face as much as possible since my skin absorbs dye quickly and obviously stains. She said well what do you want? Do you want me to cover your roots or not? Because I can't do both. Ok... I've said this to hairstylist before and they politely say ok I'll try my best.. she was very snippy and rude. I asked for a hair mask because my hair was very dry since the bleach yesterday and said she had to charge me. I told her if she couldn't be careful because she bleached my shirt the prior day and she said she wasn't doing bleach so I'll be fine.. ok but you still ruined my shirt... As she was covering my grays I asked her if the root melt was after... she said this is the root melt.. I was shocked because I've never had anyone do a root melt like that on me. I told her stylist usually cover my grays then do a root melt, she said this is how I do it I reached out to my friend that's a hair stylist and she was horrified to know she was doing this. Another one of my hair stylist friends said this : "root melt will not cover the "grey hair" bc it's "acidic based formula" it will just melt your highlights/ balayage. I usually do a grey coverage color tint in between my foils - when I'm highlighting. Some stylist do it before they start your balayage process. It just depends on the way the hairdresser works! 1 is acidic and grey coverage is alkaline based. You usually don't mix them until you shampoo the hair." When I asked her to please tone my hair darker she said she couldn't because it would turn warm and that's not what I wanted. I called my former hair stylist and she told her exactly what to do so my hair wouldn't turn warm. Well, as soon as she hung up, Danielle said "wow I've never had anyone tell me how to do my job" I told her "I've never had anyone mess up my hair before and try to charge me for a hair mask when they fried my hair" Then I asked to the salon owners information or managed. She said she'd gladly give it to me but NEVER DID. She finished my hair. I left with a "room melt" that wasn't done right. A stained shirt, no managers info. read more

This review is so overdue! But I've been wanting to write it the moment I left the salon. Rayhana is such an amazing and talented hairstylist. She was patient with me and even though I was all over the place with my explanation of what I wanted for my hair- she sat and listened and ask me a few questions and then went on and did her magic!! I couldn't believe after all these years of doing balayage with other different stylist, this was the first time I got the exact look I wanted and was asking for!! It seriously blew my mind, because I've been to so many hair stylist and no one could get my hair the way I wanted. I'm so happy with my results, and so I happy I found her. Also, The salon is so beautiful and clean and everyone that works there is super nice and friendly! Great vibes! read more

Stylist Alexxis The end result was unfortunately not what I asked for especially more so after a week has passed.. The goal was to add dimension and have it appear more natural with low maintenance but now it appears as splotchy with a reddish tone and the blonde that was meant to be toned down, is completley faded after a week? She also was very rough with my hair when it was being washed to the point it hurt. I'm not one to ever complain which is why I just pushed through it, but this was not worth over 400 including a generous tip. I now have to get this fixed. Do not recommend this service or stylist. read more

I love, love, love the results. Being a busy mom and nurse.. I don't always have time to schedule hair appointments but I am so glad I was able to meet someone like Rayhana. She knew exactly what to do.. chose colors that complemented my complexion and a style easy to maintain. Worth it. read more

I just want to start off by saying that BENNY is the best!!! My friend recommended her to me to get my hair dyed and fix the hair situation I had. My previous stylist put super huge money pieces and it wasn't quite to my liking. First of all, Benny was really accommodating in setting an appointment for me before my birthday next week. I contacted her in early July and needed to reschedule due to a prior conflict. I then asked to reschedule for earlier because I was very unhappy looking in the mirror and seeing hair I didn't like. She scheduled me on a friday before her vacation Saturday. Not once did I feel like she was rushing or trying to get me done asap because of her flight the next day. This is something I have not experienced, and this was the first time I met her. Did I say Benny is amazing?! In our consult, I let her know that I wanted to look glowy and have that jlo look. I showed her a inspo picture and the only problem with that was the color showed very warm. I let her know that I had my "money pieces" warm and didn't like them so I wasn't sure I'd like my hair lightened warm. I also let her know that I really liked her most recent post as inspo.(for placement purposes, my hair isn't light like the photo) Well 6 hours later, magic happened and my hair is absolutely stunning. I will upload photos-pending Benny's vacation. But I tell you stunning nonetheless. You know when you go to a hair stylist and you tell them what you want, and then they give you something better?! Yeah that's Benny! You won't regret going to the salon! Book your appt asap! Also the inside of the salon is stunning and beautiful. read more

I am so happy to have found this salon! I was able to get in as a last minute appointment the following next day and met Benny who transformed my hair. I have been going to surrounding salons and noticed some bad bleach placements and to add silly cuts that look like a mullet, thin with stringy ends. But not Benny no she took the time to explain to me all my options before we even started. I appreciated that so much because I didn't want to ruin the investment I've already put into being blonde. Her transformation was mind blowing! She fixed the forgotten "black hole" on the back of the head and brought me up to a brighter blonde like I wanted. I am so pleased with my service that I'll will be returning. Great product lines to try too! Invest in your self, it's worth it! Thank you Benny! @stylesbybenny Instagram read more

Elias is the best. I was recommended by my friend Linda, and have been seeing him ever since. Which ever hair goal I am currently trying to chase, Elias always gets me there. Friendly, caring and sweet is what you seek in your hair person and that is Elias. He makes me feel comfortable with whatever choices I make and listens to what I truly want, but will be honest with what is realistic or not lol. Not only is his coloring bomb, but he gives amazing haircuts as well! If you're looking for a skilled hair wizard, I recommend Elias! read more

This was my first time visiting this salon and it is so aesthetically pleasing to look at. The interior of this salon is very sleek and clean. It is very apparent they upkeep the cleanliness of their salon. I reached out to one of their stylists through Instagram and setting up the appointment was quick and easy! I do not know if you're able to set up an appointment on a website but they do have an Instagram where you can see their stylists. Judy (@hairbyjuudddyyy) worked on my hair and I absolutely loved my experience with her and at the salon. She really took her time with me to make sure I was 100% happy with the result and had such a great time talking to her during my appointment. Overall, LOVE LOVE LOVE. Take a look at their page and give this salon a visit if your hair needs some TLC! read more

Patience is key when it comes to good hair! I searched for a good year high and low for the best blonding/balayage expert in SoCal and I found her! Ray is so talented with her perfection and attention to detail. I had a color correction with bands of copper and brunette and she was able to completely correct that mess. I love my beigey blonde balayage! Her placement is going to make it so low maintenance until I decide to go lighter and add more foils in but otherwise toners will keep me looking fresh. Also the cut was so precise! It's so hard to find someone who cuts well, so Ray is the full package! Also shoutout to Langley too for assisting, she's so sweet and gentle with her washes, blowouts and foil checks. To be honest the whole salon is full of talent! Thank you girls for the good hair!

When I tell you Langley CHANGED my hair life I am not even over exaggerating. I only go to her for cuts and colors and my hair has never been healthier. I've had it messed up really bad in the past and have had really big trauma with going to a new stylist but when I found her I knew that I would never have to look for another one again. She really took the time to understand exactly what I wanted even when I didn't know exactly how to narrow it down. Even when I'm traveling or gone for a long time I still always come back to my girl. There's no better hairstylist and the vibe of the whole place is immaculate. Everybody's so cute that works there and I literally love everything about the salon and all the products they use read more

I've been coming to Rayhana for over 4 years now ever since my previous stylist over proceeded my hair. We decided to start fresh with a cut and balayage. I've been in love with my hair ever since, and now have the most beautiful and healthy hair! She is always honest when it comes to your color/cut inspirations, and would do what best suits you & your hair! The salon is very bright & modern and all the staff is very friendly. I would definitely recommend you coming here! read more

I've gone to Rayhana to get my hair done since 2017 and was super excited to hear that she opened her own salon! This salon is so pretty and aesthetically pleasing. Every corner of this salon is selfie-worthy. The lighting is on point. It's so bright and airy in there. Everyone who works there is so nice and they all dress so cute! Not only does everyone dress so cute, but they're all so talented. If you look at their Instagram, all the girls do great work! Every client comes out looking amazing and everyone gets a mini photo shoot after. I enjoy coming to this salon. Also, there's a Starbucks right across the street which is super convenient. read more

Nothing but great things to say about this salon and it's owner, Rayhana. I've been coming here since the day it opened (literally), and Ray has taken the BEST care of my hair. Whenever I tried to go lighter before, I'd end up with fried, broken, damaged hair. I'm amazed every time she does my hair, because even though I request to go lighter, the integrity of my hair is always intact. The salon is also super cute and updated. Everyone who works there is beyond nice and will be quick to offer you a coffee, water, or sparkling beverage. I added photos from the first time she did my hair- to the most recent time. read more

Alexxis Anne Marie! Where do I even start with our hair journey together?! After many failed attempts to get my hair right, I would be bold faced lying if I said I wasn't nervous to try again. I voiced my concerns to Alexxis, at a salon in Huntington Beach, and she understood exactly where I was coming from. She reassured me that she would take good care of me and to give her feedback concluding our service. What a difference it is having someone who genuinely cares and takes their time makes. We started out slow and steady, which I was totally onboard for and was a smart decision. It ensured my comfort and satisfaction at the first and future appointments. Alexxis has a good hand. What do I mean by that? I started out looking like a Disney Pixar character, you know the one, and have been completely transformed since. My hair is the longest and healthiest it's been in over a decade. I have put her through the wringer with wanting to be all blonde to deciding maybe returning to my natural color was what I wanted. After going back to dark, suggesting extensions was my next step in my hair journey. She has surpassed my wildest expectations every single time. After many years and a couple salons later, I'm pleased to inform you that I am STILL a client of Alexxis and refer you to anyone in need of a fabulous hairstylist. Thank you, Alexxis, for always giving me what I want and more with your services. I am forever grateful for you! Cheers, your forever client. read more

I love coming to Theory to get my hair done. I love everything about this salon, from the exterior to the interior and parking is always easy to find which is a plus. What I love most is getting my hair done by Judy. She is super talented. She keeps up with the times and is always relevant with what's in style. Every time I get my hair done, I'm always even more impressed with her work. She is very attentive to every detail and will make sure that every strand is done right. She definitely makes sure you come out looking like a million bucks. Thank you Judy for always taking care of me and always teaching me how to care for my hair. If you're looking for a stylist, I highly recommend Judy. She won't disappoint. read more

I have never had a worst experience with a salon in my 20 years of getting my hair done. I was impressed by Rayhanas Instagram page BUT I'm writing so that other people do not get fooled. She was extremely unwelcoming from the moment I walked in. I spent 6 hours in her chair without a word said to me. When I asked a question she was so dismissive & answered very condescendingly telling me she knows what she's doing. 6 hours later and 600 dollars spent my hair looked terrible. I went home and dealt with it for a few days because I was afraid to ask her to fix it. I decided to send her some pictures and she said her assistant would fix it. I came to the appointment & nobody was there she had me come back the following day. She took one look at my hair and realized how horrible the placement of my highlights were & how much she damaged it. She bleached me yet again to fix the problem & insisted I absolutely needed to cut it basically to get rid of all the damage I had which I did not have before. I had healthy long hair just wanted some highlights. She chpped it off and trust my color does not look like I paid 600 dollars for it. See pictures. I would not recommend this salon. Don't be fooled by their filtered Instagram pictures. My hair is fried & the color is absolutely horrific. read more

I have nothing but wonders to say about this salon and the owner Rayhana. In the past, I've jumped from colorist to colorist to achieve the perfect blonde - natural without the damaged dryness that comes with it. That search was over when I met Ray back in January 2019. She is the only colorist that touches my hair as she KNOWS hair. My go to style is a low maintenance natural look that allows for a 9-12 month growth out! What I love the most is that my hair feels healthy, looks beautiful, and matches my needs of keeping it natural looking without the constant coloring. I get compliments all the time as anything she does is a knockout and I always leave happy with my look. In addition to great hair, the salon's atmosphere is tranquil yet chic with easy parking in the back. I've been making the commute to this salon since it opened because great hair from a great individual is worth it. Thanks Ray! read more

Langley is my girl! I have been going to Langley for about 4 years and this girl has made all my hair dreams come true. She literally saved my damage hair when I first came to her.
