Such a fantastic experience with Angie + Brenda!! I showed them a picture of what I was looking for and my blonde balayage turned out BETTER! They are true artists and five stars is not enough. Will be referring all friends and family to this salon.

I have been going to Jennie at Studio W salon for a few years now and I have never had a better hair journey! I always leave feeling gorgeous! The ambience, the friendly faces and the service are top tier.

I’ve been coming to this lovely salon since it opened almost 10 years ago, and the owner has been my hairstylist for 18 years. She’s incredibly knowledgeable and truly passionate about her craft, which always shows in her work. I absolutely love the warm, friendly atmosphere, it always feels so welc...oming. Plus, the tea and coffee they offer are a lovely bonus! read more

My stylist was very good at delivering exactly what I asked for. My hair is starting to thin out on top and I asked for a style that would help hide this and she absolutely delivered. Money well spent!

Daniela is the sweetest, and she always gets exactly what I love in my hair. I always leave smiling ear to ear because she knows what she’s doing, and having curly hair I’ve always been so cautious and never have had good experiences but Daniela knows how to do curly hair.

I was greeted so nicely upon arrival and offered a beverage which I thought was super nice. Daniela did an amazing job and was super thorough in styling my hair. Love this salon and Daniela!

I have been coming to this salon for 4 years and I have never been disappointed. I’ve had multiple stylists do my hair and they are all professional and enthusiastic about their work. The environment is welcoming peaceful. If you haven’t gotten your hair done a million times or looking to get it don...e for the first time i highly recommend Studio W Salon! read more

Another great haircut and style! Mercedes does a beautiful job giving you the style you want and is so sweet with suggestions. I am excited for my next appointment!

Angie was attentive and gave me exactly what I was looking for! She gave one heck of a curly cut! 5 stars all the way!

Had a great haircut. New look. She took her time and did what I wanted.

Julee did amazing with my layers. I felt very comfortable in her chair. Her haircut literally lifted a weight off my shoulders… it’s not as heavy as it used to be (I have very thick hair) my hair finally looks healthy and bouncy. I’m in love!!

Amelia gets curly hair! She took the time to go over what I was hoping to accomplish. She explained how to emphasize the curls, how to hydrate dry hair, how to curl and how to straighten.

Always clean and the ladies are super nice. Very professional and my mom and I have been coming here for years. Great location in Castro Valley. Love the color and the blow out. Thank you for girl time and making my hair beautiful.

Jenny & Lily are super professional and accommodating for appointment. Happy with the hair coloring.

Kayla did such a great job with my granddaughter. She got a trim and fairy highlights. My Granddaughter was nervous and antsy , but Kala was so good with her and she felt like a princess when we left.

Angie is so great! She listened to how I want my perm to look like and she delivered!! Highly recommend her!

Amelia was great! I like my haircut and I also appreciated that she checked in with me frequently to make sure we’re both in alignment throughout my haircut.

Amelia is fabulous with my hair. Such a gift

I showed Mercedes a picture of what I wanted and she absolutely delivered! She adjusted it a bit to best fit my features and explained the whole process. A nice mix of silence and super fun conversation. The salon is constantly kept clean with a vibrant but relaxed energy that makes you feel super c...omfortable! read more

I recently moved and needed to find a stylist. I am so happy I was able to book with Moni. She was super attentive to what I had to share about my hair and its journey. Super communicative and knowledgeable, she explained each step and each product she used while cutting and styling my hair. Everyon...e else at the salon I spoke with was super kind and communicative as well. This is an excellent salon with excellent service. I'll definitely be coming back! read more

Alli Girard has been my hairstylist for over 2 years now and is consistently outstanding. Knows what I want (but always checks) and gets it done flawlessly each time. A-plus!

Professional, friendly and clean. Jennie and her staff are amazing. Jennie listened to what I wanted done and made suggestions that made my end results better than I had hoped for. I made my next visit appointment before I left!

Love this salon, great job, such a cute cut from Ali!

I know regardless of which salon worker I have for my appt, the cut will come out wonderful no matter what. The staff are friendly, warm and welcoming. I’m one of those that often feels a bit awkward trying to make small talk but they make it easy.

Amazing staff amazing work I’m thrilled that I’m satisfied with the work they did on my hair.

Can you get my hair really blonde?
«This is a tough question to answer without seeing your starting hair color. But yes, it is possible to lift even the darkest of hair to a blonde shade, but it may take multiple visits to the salon to do it safely. This is also known as "high maintenance" blonde because there will be a lot of upkeep to pull off this look and keep your blonde hair looking good. As extreme lifting can be complex, we often consider this a color correction service.
