Hair Bar NYC

Tip: if you have thick hair and are getting keratin, buy a gas mask and formaldehyde filters for the mask because the fumes during the blow drying process can be very painful. I got this mask:
with these filters:
Got my keratin done by Nancy Rozewicz in June 2015 and loved the effects. I have super thick, curly, and frizzy hair and got the strongest keratin. The results were smooth, frizz free, and with some wave, just like I wanted. It started getting frizzy again around ²⁄₃ months but the results lasted about 6 months. At 7 months my hair has mostly returned to its original state, but still less frizzy than it was to begin with. Can’t say enough good things about Nancy, she was a delight and gave me excellent service.
Nancy no longer works at Hair Bar, but she gave me such excellent service that I looked her up on Facebook and contacted her to do my keratin again. She’s working out of her home in Kensington, Brooklyn and also travels to her clients. If you’re looking for Nancy like I was, you can contact her at 646−612−4036. She also does color, check it out at

I’ve had keratin several times here. Can’t beat the price and lasts several months. My hair gets so knotty its unbrushable if I wait too long. This helps a lot with that.

Emily was awesome, I came an hour late due to the trains and they still took me! (thank you thank you!) It’s been five weeks since my treatment and I have been alternating my high end shampoos, sulfate free and shampoo containing sulfate (only because my hair is thin and it weighs my hair down and gets greasy if I only use sulfate free) I have a little bit of shape coming back but if I blow dry my hair halfway, its stick straight. I have not used my straightener once. Cannot wait to book an apt for my sister when she visits!

Thanks for your comment, Hairbar. I would go back to fix it if it was only the keratin not working, but with the dandruff… wouldn’t risk it again.

this is my go-​to place to get the keratin treatment! My hair is always done well, the stylists are extremely friendly, and they’re constantly having promotions. I’d highly recommend the Hair Bar!

I was brought to Hair Bar NYC because of a Groupon for keratin. I ended up booking a balayge as well to fix what I already had in my hair. I ended up coming in late by almost 30 minutes but they were nice enough to keep my appointments. I was welcomed by Alla as soon as I walked in and she started on the balayge and consulted me on what color I prefer and told me what she would be doing before actually applying the color which was much appreciated.
After the color Alla went on to do the Keratin treatment. She took pictures to show me how it looked as we went. She made sure to not do the color too light because the keratin would make it lighter. The color came out perfectly because of this. The color is seamless!
She took her time on her hair and it shows.
I’m super happy with the outcome

I stumbled upon Hair Bar NYC nearly 2 years ago and have been a loyal customer since! For years, I struggled with frizzy hair that broke all the time but I’ve seen a drastic change since I started getting keratin treatments here. Each treatment has lasted 5 – 6 months and my hair is now significantly healthier and stronger. You can’t beat the quality and price, which is why I now travel all the way from CT to continue going here. Thanks Hair Bar NYC!

My first experience with Hair Bar was two years ago where I received a Keratin treatment and a hair cut. My curls are type 4a, and I left the salon with soft and pin straight hair.
However, a few days ago, I visited the Hair Bar on Madison and had a completely different experience. My hair stylist was Rebecca who assured me that she had experience working with African American hair yet her techniques implied otherwise. But before I describing her weaknesses, I must recognize her strengths. She was extremely nice and held great conversation. Additionally, I could tell that she was diligent and sincere about her work as she took her time in every process of the keratin treatment.
My only complaint is that she lacked proper technique for styling kinky hair. First, she did a poor job of blowing out my hair as my curls were still very tangled and not stretched upon completion. Because the blow out was poor, it was very difficult for her to straighten my hair. She detangled my hair as she was straightening and was offended when I asked her to begin combing at the ends then work her way to the root. I left the salon with stiff and sticky hair heavy with product. When I got home, I had to re-​straighten my hair because she did not get my roots well. Additionally, I added oil to help with the stickiness. In the end, My hair was soft and straight but I cannot fully accredit these results to my hair stylist.
Besides from the stylist, I received the 24 Karat Keratin treatment. It does have formaldehyde so the blow drying process is somewhat difficult to sit through. Yet the results truly make my hair healthier and easier to manage.

I had such a bad experience here. My stylist was Alla and she was extremely unprofessional, rude, pushy, and talked back at me towards the end when I had asked some simple questions about my hair. She also was rough when when she was straightening my hair, and broke off a lot of it on the top. I would not recommend this place to anyone. On top of that, the facility itself is extremely small, and there is no waiting area (you’re told to sit in a rachet dark hallway).
I would recommend Keratin Bar over this place — they charge you about the same price as here.

I came here on Columbus Day, a little under 3 weeks ago, for the keratin treatment. My hair is normally very frizzy and curly, so I’ve been dying to do this treatment. Afterwards, I couldn’t believe it, my hair was so straight and smooth! I didn’t wash it, put it behind my ears, tie it up, anything for 72 hours as the girl recommended so it could be as strong as possible.
After the first wash I was impressed, it dried nice and straight, no frizz. I kept the washing to once every 5 – 6 days, as the girl informed me the more you wash it the shorter it will last. I had no idea after less than three weeks and the FOURTH wash it would start drying half straight half curly. There are random blocks that go back to the curl, random sections that have half curl kinks, and the rest — well that managed to stay straight.
Very disappointed, even for the unbeatable price it should have at least lasted a month.

Booked this appt on Unilocal.Walked in 10 minutes before it and was told that this isn’t the first time this has happened but that they close at 9 (it was just after 8) and they don’t take clients after 7. I was going in for a simple hair cut.
So, correct me if I’m wrong, but what you’re saying is that you know there’s a problem with bookings on your Unilocal page and you haven’t fixed it? So glad I came here at 8pm on a Thursday. For nothing.

I wouldn’t know how the service is. I booked an appointment using Unilocal.It was confirmed through Unilocal and added to my calendar. I got to this place to only have a ride front desk girl tell me no one could help me and to try their website next time. Really? You couldn’t be more polite or even try to accommodate? I did my part and booked my appointment instead of just showing up. I would have gladly waited but to just be blown off when I DID make an appointment is rude.

I can’t say enough about this place! Gina just finished my hair and I couldn’t be happier with the results. They have all types of keratin treatments so if you just want to get rid of frizz, this is your place! If you need stronger strength or just a light treatment, then give them a try! I used to do my hair with its natural wave and then I switched to very straight and this time she added a little lift to it. The place is always busy. They are so sweet there and extremely professional. Gina is the best and I wouldn’t pay hundreds of dollars to go to a fancy salon when you can get as good a treatment, if not better, at HAIR BAR NYC! Thanks Gina!!!

I went to Hair Bar for the Brazilian Keratin treatment, I’ve only done it once (elsewhere) and loved it but was worried it wouldn’t come out that well because it was significantly cheaper. When I called to make the appointment it was 95 $ but after I arrived and did the consultation they informed me it would be 145 $ because my hair is so long. Sucks but I guess that’s fair.
Emily was my stylist, she was really sweet and did a great job. I picked the 24 hour one which is stronger because my hair is very thick and extremely curly. The fumes are crazy strong so be prepared, they’re no freakin joke! Anyway, I decided to keep the treatment in for 3 days instead of only 24 hours to maximize the effects… and boy did it work! I’m so shocked at how soft and wavy my hair is! Wow, so this is what it feels like to have «naturally» straight/​wavy hair?! You girls have it so easy!!! Lol
Normally if I wash and air-​dry my hair it looks crazy frizzy and wild (very curly Dominican hair), takes 2 hours to put in rollers and then blow dry but after the keratin I don’t even need to blow dry, flat iron, NOTHING! I did not expect these results (thought my hair would still be somewhat curly, just more manageable but I’d have to flat iron). I’m soooo happy with my results, I’ll definitely be back in a few months. Thank you Emily!

I originally gave this place 4 stars since my hair was smooth after washing, although there were a few complaints which I overlooked.
Although hair was smooth, it only lasted 2 months. I even purposely bought sulfate free shampoo for treated hair to try to make the treatment last longer. I was told the treatment would last 3 – 6 months and it definitely did not.
Also, the dandruff continued from the keratin burning my scalp when being applied. There were points where if I shook my head, it looked like a large amount of dust was coming out of my hair. It has gotten better after 3 months, but still worse than before the keratin treatment.
Then, there’s the hair loss. I started losing a lot of hair. It has not stopped for the 3 months since the treatment. I am now looking for hair growth products
It’s a shame. The hair texture was great but short lived. And the dandruff and hair loss side effects have really changed my mind. Never again.

Got a last minute Friday afternoon blowout with Laura before catching my train at Penn Station. I called 5 minutes before showing up and they easily accommodated me. Easy to find walk-​up location.
Laura was very sweet and I enjoyed talking to her. She made sure I was comfortable and loved what she was doing. I have very long, thick hair so I know what a nightmare blowouts are (for the stylist who gets stuck with me!). The blowout took about 45 minutes to an hour.
Price was a steal! Total was $ 38 with tax.
Reason for not giving 5 stars: the ventilation was awful. There were two people getting keratin treatments done and I was bawling the whole time. Nothing my styling could do about it but next time I will ask to sit away from the Keratin (window seats) or possibly try a spot that doesn’t do keratin treatments at all.

I was in New York on business and decided one Sunday, «what should I do?» I said, I will search Unilocal for a salon that opened on Sunday and was just walking distance from my hotel, the Roosevelt. I called made my reservations! I was excited, my hair looked a HOT mess!!! So, I walk into The Hair Bar the staff was so pleasant and they asked if I preferred a specific beautician. I responded, saying any available beautician would work for me. Alla helped with my transformation!
I entered the salon with a feeling of please help my hair, to WOW, I never knew my hair had this much potential! I swear, I felt like Cinderella after she finished my hair!!!
THANK YOU ALLA, YOU ROCK!!!

I did the keratin treatment with Samantha. She told me everything I needed to know to maintain my luscious locks. She was extremely patient with my thick hair. The chemical smell was definitely a little uncomfortable but Samantha always made sure I was okay and offered me a mask and water.
The process took over 2 hours. Samantha then gave me a nice trim.
3 days later I washed my hair and I am amazed by the results. There is little to no frizz and maintenance is much quicker. I have tried different treatments in the past and none have worked. I will absolutely be returning to Hairbar when I need another treatment.

I wanted to find a place that would do Keratin treatment for men, and Hair Bar was affordable and nearby so I tried it. It’s a pretty simple salon, nice and casual. I had a positive experience five months ago, so I went back on Wednesday.
The keratin treatment makes my frizzy hair soft and smooth. I don’t really have to put any work into it. Sure, it’d be easier to just buzz my head but I’m stubborn. The whole process was fairly quick: they do the wash/​application/​ironing, and then after a day you wash it out and that’s it.
Nancy is awesome, she did a great job both times. Highly recommend getting an appointment with her.

I came here for a groupon. I got keratin treatment for $ 150 instead of $ 250. Seemed like a good deal but have to see the results.
I would give it a five star just for my stylist Emily. She is so genuine and nice. Just really love her. She’s an asset to this business.
Samantha was doing reception but is also a stylist and is so sweet and amazing. Love her as well. Also an asset.
But I am reducing the stars cuz there’s another stylist there, Alla, who put the AC on and had the window open – hello it’s winter and freezing. But she didn’t care about the clients, just herself. She even sat on the couch where I left my coat and moved my coat and was touching my stuff – There were other chairs so why mess with my stuff? It just made me uncomfortable. It was so cold thanks to her that I had to put my coats on anyway. Literally am wearing two down coats cuz I’m so cold.
Hate this place but love the other two stylists. Still, I would never come back here cuz Alla made me feel so uncomfortable and cuz it was freezing and Alla wouldn’t let anyone close the window or turn off the AC.
Will update review with hair results later.
