Sheila is a hair genius. She made my greys go away making me look 5 years younger. She also did a natural look makeup for our photoshoot formy work. She does wonders for my hair and face. I would highly recommend her and everyone at her salon.

20+ Years and Still the Best! I’ve followed Sheila to different salons for over 20 years because she is simply the best. She has navigated my hair’s transition from curly to gray with such expertise and care. Her new space is stylish and cozy (you’ll want to stay for coffee or wine 😝), and the SF location is perfect for a "Me Day" of shopping and people-watching. If you want someone who listens, uses clean products, and makes you feel amazing, see Sheila!

I have a hard time finding a hairdresser who perfectly matches my needs and the couple running this place has done that and then some. Rarely is it that I fully trust my stylist with my hair but the work these two do is nothing short of superb. You will be hard pressed to find someone else as professional and personable as these owners.

Sheila did a fantastic cut on my hair. Went in ready for a new look and she succeeded in every way. I got rave reviews over the cut and she is so joyful and thoughtful. Truly a joy to be with.

Due Collective is an amazing salon that makes getting your hair done a great experience! Sheila is awesome, both as a skilled hair stylist and a warm and welcoming person. She's hilarious, easy to talk to, and able to cut, color, or style your hair perfectly. If you have really thick hair, Sheila is the perfect stylist for you!

Duo Collective is a top shelf salon with a warm comfortable feel. My stylist, Catherine, gave me the best haircut I have ever had. The space is bright and airy and well appointed. I’ve been to a lot of salons and this is my favorite by far.

Sheila Vergara at Duo Collective is an amazing hair stylist, colorist, and genuinely wonderful human being. From the moment you sit in her chair, you feel truly seen and listened to, and she has an incredible eye for color and shape. She doesn’t just follow trends but tailors everything to you, your hair texture, lifestyle, maintenance comfort level, and what will actually look great long after you leave the salon. The entire experience at Duo Collective feels elevated but relaxed, and I trust Sheila completely with my hair. Also, a quick shoutout to Elkin, a master colorist, who once went above and beyond by fixing my wheelchair when I had a broken ankle. That moment perfectly reflects the care, kindness, and professionalism that make Duo Collective such a special place.

Worth every mile. Elkin has been my hair color specialist since 2020. I live in the East Bay and drive to San Francisco for my hair color and I do it every time. His color work is consistently flawless, incredibly natural, and customized in a way that never looks overdone. My family and my friends assume my hair color is natural, that’s how seamless his work is. What truly sets DUO COLLECTIVE SF apart is their intentional approach: low-toxic products, a clean-air salon environment, and a space that feels calm, warm, and thoughtfully designed—not your typical salon vibe. Exceptional color artistry, a healthy salon environment, and people who truly care. I wouldn’t trust my hair with anyone else. Highly, highly recommend.
