Customer Reviews for Onyx Hair Salon

Tiffany Luu — 5/5 (via Google) Mar 22, 2026

I’ve been seeing Alessia for a few years now and truly can’t imagine going to anyone else! Before her, my hair was very dry, and I could never maintain the balayage color I wanted. With her help, my hair is so much healthier and I’m finally reaching my hair goals! She always gives the best advice for keeping my hair healthy and my color fresh. She’s incredibly talented, so sweet, and truly cares that you leave feeling your absolute best. She’s worked at previous locations and is now here at Onyx Salon. She’s so great that I happily followed her! Everyone at Onyx is also very friendly, and the salon is super cute and clean. As a soon-to-be bride, I’m so grateful to have her and this salon helping me maintain my hair goals before my big day. Highly recommend!!

I had a great experience at Onyx Hair Salon with Anna! She was sweet, professional, and made me feel comfortable right away. I booked a last-minute appointment for a haircut, and she still took her time and gave me plenty of attention and care. She listened to what I wanted and delivered exactly that. I was so happy with the results that I went ahead and scheduled another appointment with her for color. Highly recommend!

I ended up coming to this salon because of a TikTok they posted about getting 50% off a full service back in December. I’m honestly so grateful I took the opportunity to go and get my hair done with them. Emily has been taking care of me since my first appointment, and she always listens to every little thing I express about my hair. We just did a haircut and glaze last Saturday, and I’m very picky with my haircuts, but she met all the expectations I had about how I wanted my hair done. I always leave feeling really happy with the results. Emily is amazing and I honestly wouldn’t hesitate to trust anyone there with my hair, they all seem very skilled, caring and professional
