24 Karat Brazilian Keratin Treatment – Special Offer


The 24 Karat Keratin Treatment is a cream-based formula designed to straighten hair while eliminating frizz and increasing shine and smoothness. This treatment also significantly boosts humidity resistance, allowing hair to remain straight and smooth even in the most humid environments. The 24 Karat formula contains natural oils, such as Boabab Oil, Argan Oil, and Mineral oil, all of which work to condition the hair and add heat protection. Other ingredients, such as hydrolyzed keratin, hydrolyzed soy protein, and hydrolyzed collagen, transform dry and damaged hair into an unbelievably smooth and manageable hair.

24 Karat Brazilian Keratin treatment is the strongest among our Keratin’s. It contains almost twice the amount of collagen and cysteine than the original keratin treatment as well as added ingredients such as essential oils and proteins. This treatment is highly recommended for individuals with coarse, thick and or very damaged hair.

You can wash hair after 24 hours. However we strongly recommend that you leave it in longer (up to 72 hours) to get the best possible results.

    I came across Hair Bar NYC while searching for a new keratin option as the results from places I had been going to were becoming more and more inconsistent.

    From my first treatment, I couldn’t be more pleased with the results — and a bonus, the staff is super friendly and the vibe is chill. I’ve been getting the 24 Karat treatment and on average, it lasts 4 months (pro tip: if you color your hair or have highlights, best to get the keratin done within a week after for the best results).

    Really love Hair Bar on Madison and on Third Avenue. Everyone is super nice and thorough. I should say that I prefer 24 Karat over the Silk Touch which I tried once. This one seems to not mess with hair color as much as Silk Touch.

    I’ve been going to Hair Bar NYC for about 3+ years now. I went to the Kenmore location before going to the Madison location, which is now my permanent spot since it’s the closest to me. Lynda has done my hair for the past two years and I love it. Today, I had the 24k and a 1 color process. My appointment lasted 3 hours and Lynda was very thorough. The treatment can last over 5 months for me. My hair looks great and I’m looking forward to a frizz-free summer! Thanks, Lynda!

    Lynda from the Madison location is the best! I’ve been going to her for about 3 years. As long as she works at Hair Bar, she can be sure she has me as her client. She makes me look beautiful. I love my hair. She’s a pleasant person and with a great personality. She makes sure I leave her place happy and looking fabulous! Thank you Lynda! My #1 hairstylist ❤️
