    Stephanie Picos did an incredible job. Best part of it all, she wanted to keep my hair healthy hence waiting couple of months to go a little lighter. I went to the pool couple of times and I honestly think it made it even lighter. I absolutely love it now but I definitely need to touch my roots! Thank you girlie for your service and patience with my hair and me ? See you in a couple more months.

    Took me almost 10 years to find someone like Ray and now I won't ever let her go!! Insanely talented and educated in what she does. It's also such a relief to know I can sit in her chair and get my own work done and trust she's always going to do what's best for my hair with my goals in mind.

Ray killed it and I am so glad I found her! She brought my hair back to life! Her attention to detail shows in her work! She really takes her time and makes sure you get good results even if it means adding more dye & washing multiple times. Thank you for being patient. I trust the process because I know I'm in good hands! Thank you so much Ray & Alexis for taking care of me. Can't wait to come back! All the girls that worked there were sweet. Good vibes. And every girl that came in, left... read full review
