I've been coming to Lauren at Union + Mane for nearly a decade, and honestly there's no one else I'd trust with my wefts. She's a total boss -- the kind of woman who built something real through sheer hard work and genuine love for her craft. What sets her apart isn't just the skill (though the attention to detail is next level) -- it's how she makes every single client feel like the only person in the room. You never feel rushed, never feel upsold, never feel like a number. She cares. Full stop. You feel it the moment you sit in her chair. If you're looking for someone who will take your hair seriously and treat you like a person, not a transaction, Lauren is your gal! read more

Lauren could not be more skilled at what she does!! She is simply the best when it comes to hair extensions- truly top notch. I first came to her a year ago during a time when I felt like my hair was thinning and I was losing confidence. She reassured me that extensions would not harm my hair, but instead would allow it to grow while helping me feel like myself again. She was absolutely right. One year later, I'm obsessed not only with my long wavy extensions, but also with how thick and healthy my natural hair has become!!! Her technique is incredibly careful, precise, and secure. My extensions always feel snug and comfortable- never itchy or loose like you sometimes hear about. Beyond skill, Lauren is such a kind and genuine person. She truly cares about your long term hair goals while helping you feel confident in the meantime. She always makes me feel heard, comfortable, and cared for at every appointment. She's organized, detail oriented, and creates such a welcoming, beautiful workspace. I genuinely could not recommend her more. Huge fan! Thank you, Lauren!! read more

I met Lauren eight years ago when she first replaced my hair extensions, and I knew immediately I had found someone special. From the very beginning, she was kind, upbeat, incredibly patient, and always willing to go above and beyond to accommodate my very specific hair needs. She did an absolutely impeccable job--and I've been seeing her regularly ever since. Not only is Lauren an extraordinary hair artist and stylist, but she also has a phenomenal eye for design and aesthetics. Her space is beautiful, thoughtful, and a true reflection of her creativity and care. It has been such a joy to watch her grow her business and truly thrive doing what she loves. I am very picky about my hair (especially having very thin hair), and Lauren always listens, offers thoughtful ideas, and consistently delivers phenomenal results. I trust her completely, and I am deeply grateful for her talent, professionalism, and heart. I couldn't recommend her more highly! read more

Union & Mane - Hair Extensions Near Me - San Francisco, California

Lauren is amazing at what she does!! Hands down the best and most affordable in the city (and out of the city TBH). She super transparent about pricing and her recommendations for what she thinks will work best for your hair. I've had all different kinds of extensions and Lauren listened to my concerns and recommended a blend of two different types based on my needs. Not to mention she (and all the other stylists/renters at Union and Mane) are the sweetest and friendliest people and make it fun to visit and hang during your appointment! The salon is so cute and you can get a wax or shop the amazing vintage clothing while you wait for your appointment! Cant wait to go back and visit. Thank you Lauren! read more

A more aesthetically pleasing salon in San Francisco could not possibly exist! Not only is Union & Mane gorgeous, comfy, and peaceful, Sonia is a magician. I cannot say enough good things about Sonia Huertas. She is a seasoned colorist and stylist who takes the time to consult with her clients and give a thoughtful, comfortable service that leaves us refreshed and beautified. I have been seeing Sonia for years and she has taken my hair all along the color wheel and back-- from long and layered to short French bobs, she does not miss. I can't thank you enough, Sonia for your expertise and ability to manifest all my crazy ideas! Congratulations on your new beautiful salon and maybe let's go purple next! ;) read more

Lauren did my extensions for years while I grew my real hair out. She always worked with my budget, and was so easy to talk to during our microlink sessions. I can honestly say no one suspected I had extensions (which is what you want), and I would get compliments on my hair all the time! read more

If I can leave a billion stars or more I would! Lauren has been my hair stylist/extension perfectionist over the last 3 years and I couldn't be any happier with her. I've been struggling over the years finding someone who can work with my curly hair/medical concerns with alopecia and Lauren was kind enough to explain how the process would be and was so informative from the very beginning on all aspects of having extensions (ex: hair texture, how much my hair can handle, color matching, different options of extensions for different parts of my head) and so forth. I will forever be thankful for the confidence Lauren gives me and for the hair growth a billion percent, you'll be happy with Lauren!! read more

I have been going to Sonia for years and every time I leave her chair I feel and look amazing.She is an expert in color and the blow outs are to die for!

Lauren is incredible! I am so happy with my hair and this is such a good investment. I would recommend her to anyone.

6 stars if I could. Lauren has done my extensions for over a year. When I found her I was down so bad from a bad bleach job and was left with a chemical cut. I really wanted a stylist who cared about every strand of hair (because I maybe had 100) and needed someone who could get me back to my natural hair. Selfishly I cannot bring myself to post my "before" hair because it was that bad BUT I will post what my natural hair looks like a year later after having 2 rows of wefts that I would move up every 7-9wks. Lauren saved my hair and mental health and I am SO appreciative of all the times she's been able to do move ups and dry styles. read more

Union & Mane - Hair Extensions Near Me - San Francisco, California

Where to even begin...Union & Mane is the best salon in San Francisco, no comparison! Lauren is so skilled at extensions she has actually managed to make my hair healthier and gave me the best hair transformation of my life! I had very damaged over processed blonde hair and now thanks to Lauren and Sonia the colorist, I have beautiful long red/copper hair that I love and that not only looks but feels so much healthier! Glow up! Lauren is seriously an expert whose work speaks for itself, she is the most gentle and talented extensionist I have ever experienced...like I can't even feel the weft at all and install was so gentle. She is extremely knowledgeable of everything extension and hair care to a degree I just haven't felt from any other stylist before. At this point I would trust her with my hair in any situation and give her a PhD in extensions lol no joke! Sonia is amazing at color and has totally transformed my brittle blonde to bouncy healthy red....and the cherry on top, the price point is great and the salon itself is seriously so beautiful. I cannot recommend Union & Mane enough. read more

Lauren is an absolute legend in this industry and came highly recommended by my longtime hair stylist. I was amazed at her level of skill in blending my very mixed hair type with two rows of hand-tied extensions that matched my curl pattern and natural color perfectly. Moreover, Lauren is a phenomenal person. Even after I needed to cancel twice due to health reasons, and eventually had to take a break from the service, she was understanding, supportive, and didn't charge me an astronomical fee. It's been several months since I've seen her for a service and I can't wait to return once I'm able. I cannot recommend her enough to anyone seeking this service. read more

Lauren is the best in the game, let alone the Marina District. She offers various hair extension methods and is really honest about what will look the most realistic with your individual hair. She also cares a lot about the long term health of your natural hair, which I really appreciate. Her color matching/blending skills are unreal... the extensions look so authentic. She is also a lot faster (and nicer lollll) than other extension experts I know. read more

Lauren is the absolute best!!! I've gone to her for years for my extensions and ive seriously never had anyone do a better job.

My girl where do I even start!!! Not only are you a magical person, you're a great friend and stylist! I love coming to get my hair done by you. We have the greatest time and the best conversations. I love you so much. You're the best. read more

Union & Mane - where do I even begin! So excited for Lauren to have opened her shop in the house of beauty with an amazing group of women. I've been getting extensions from Lauren for about two years now. Lauren helped me ease into extensions first with tape ins, then wefts, and I'll never look back! She is the best at her craft, not only the attention to detail in the actual placement, but her background in the hair industry allows her to give great advice. She personally tailors each of her client's installs to their specific needs and goals while educating on the best approach and maintenance for your hair type. She is so dependable and bends over backwards to make sure she accommodates her clients first. I would recommend Lauren to anyone looking to achieve length and volume, and getting the best quality in the city! The one thing I used to struggle with was finding someone to dye my hair with extensions - then Lauren introduced me to Sonia at U&M - she is an absolute color queen! She's done so many different looks to match whatever current extensions I have in and it always blends flawlessly. These two are not only the best in the biz but they're also fun to hang out with in their beautiful shop. Seriously, I can't say enough good things about Union & Mane. Thank you ladies for always making me feel my best! read more

Lauren has been making my hair dreams come true for the past 6 years!!! I was so nervous when I first got extensions and not only did she ease my mind, give me the most gorgeous hair ever (that I won't part with ever), but we also became best friends. 6 years later - I'm flying up from LA to SF to see her because she truly is the best of the best!! So proud of her for her new spot :) read more

I absolutely love love love this this place. I've been getting my hair done by Lauren for about three years now and I would never go anywhere else, she is dedicated to making me totally happy with my hair, I ALWAYS walk out with a huge smile. I went from I tips to wefts to I tips then back to wefts and it's been a great experience every time. My natural hair is healthy and keeps growing because Lauren is very gentle and careful. And if you're looking to change up your look and need color Blair is amazing and can do it all. I am one VERY HAPPY customer and I highly highly recommend Union and Mane. read more

Lauren of Union & Mane is an absolute artist. I've been seeing her for extensions for five years and not only have been delighted by the exceptional quality of her work, she also goes above and beyond to deliver a fantastic experience. Additionally, every colorist and blow-out styler I've been to - in over 10 cities - raves about the extensions, saying they are the best they have ever seen. When other hair pros rhapsodize, you know you've got a good thing. Lauren is a star. Book her while she still has windows - she's in high demand for very good reason. Love Lauren! read more
