Blowout Brazilian Keratin Hair Treatment Proven Formula 120ml Straightening Smoothing Repairing Formaldehyde-free Sin-formol Proven Tested All Hair types

I was skeptical, but I finally tried this. My hair is naturally curly and bleached blonde. I followed the instructions, and I’m thrilled with the result. I can tell where I still need to use the flat iron a few more times. And I’m keeping it on 3-5 days (I read somewhere that longer is better). I’ll update my review after I see how long it lasts. UPDATE: The treatment lasted for months! I unfortunately tried a different version this time, the one with “botanicals”. BIG Mistake! The fumes burned my eyes and the stuff burned my scalp! I returned that one and reordered this one so I’ll have it when I’m ready for the next treatment. I’ll never switch or try anyone else’s brand!

I was very skeptical on using this at first. I followed the directions as closely as possible, left it on my hair for 36 hrs before washing, and I love it! The scent is bad, chemicals burned my throat and eyes FYI, but my hair is smooth and soft. It has made my hair much more manageable, it’s been a week now and I hope it lasts for awhile

I have fine, curly, fuzzy hair, especially in the summer humidity. It continues to grow with the humidity. I can straighten it with a good flat iron but it won't hold in the summer - not so much a problem in the cold weather. I wasn't willing to pay $350-$400 for a salon treatment that might last 3 months. I checked out a lot of reviews and went with this product. The price and the results were more than I could ask for and was very pleased with my results. Just do what it says, each step, wear gloves, ventilation, etc. I admit I could only make it two days without washing and it still lasted as stated. I've done it myself every time and it does take the stated approximately 2.5 hours and my hair is just below should length. For the length and thickness of my hair I was able to get 3 uses out of the bottle.

This formula works great on my 4a/4b hair. It straightens and strengthened my hair. I have used it twice but the smell is so strong that I cannot use this again. My eyes burned so much and my nose burned. I guess the second time I didn’t have good ventilation. I will have to switch to something less harsh.

I spent $300 getting a Brazilian blowout from a hairdresser and I couldn’t afford to get it again. So I searched for a DIY alternative and ran across this product so I decided to try it. It came with step by step instructions that was super easy to follow. I used half the bottle for my first try and it worked just as good as the Brazilian blowout from the salon. The first sesh lasted me about 3 months bc I have really long curly hair. And I used the other half of the bottle to do it again once my curls started coming back in. The product itself smells delicious, but when I applied heat to my hair, it created fumes. Once my hair was done, it smelt just like the product. Overall, definitely worth the buy! I loved the result both times I did it. Super easy to do on your own and super affordable. Def gonna buy it again. Tips if you purchase: • You will definitely need to wear a face mask and goggles, and prolly apply the product in a room with open windows. I did this in my bedroom and I could literally see the fumes even tho my fan was running, it was so cloudy in the room. My eyes would water from the fumes too. • My hair type is curly but I also have thin hair, so my hair didn’t need much product. I would apply the product, and then comb out any excess product to use on another section of hair. • I found that the more times I went over my hair with the straightener, the better the results were. Each section I went over exactly 10x’s with the straightener, but I would only recommend this tip to people with thicker or curly hair.

Followed the instructions exactly. I only washed my hair after 3 days + touch ups (as it suggested) and my hair is wavy. I just blow dried it and it's not straight. :( My hair was wavy (not curly) before using... It stinks horribly when you use it too. For the 3 days my hair was straight (but that due to using the flat iron on it) yet it was not "keratin treatment" straight nor shiny. It just looked like my hair was fluffy straight & dull. :/ They really should return my money.

Well, it definitely softens your hair and I’d say it does a good job. However, the fumes were absolutely horrible. My eyes burned and would not stop watering, my throat burned and I was coughing a bit, etc. I made the mistake of using my bare hands to apply this (completely my fault for not realizing it has formaldehyde in it) so DO NOT USE YOUR BARE HANDS!!!! It dried my hands out excessively and when I got my hands wet (such as washing them or when I took a shower), they would get so pruned and start peeling so bad that I couldn’t even wash my hair. Overall, the product did its job but I feel like it made my hair look thinner and despite being very precise and gentle with the whole process, I feel like I lost more hair than I expected to. It was nothing crazy, I don’t have bald spots, but this stuff is strong so use at your own risk or go to a professional.

I was unsure if this product because I’m no hair stylist nor a girl that does own hair unless I have a lot of time. This product took about 3-4 hours to put on and use, keep in mind- I have thick long hair, past middle of my back. I LOVE THE RESULTS! I can wake up, wash and go! Not hair stylist good, but worth it. Hair has minimal damage, and it’s perfect! Just make sure to have time for it.

Ich bin mit dem Produkt zufrieden. Ja es macht etwas trockene Haare aber glättet meine sehr starke Krause mit wenig Lotion und einem viel geringeren Zeitaufwand. Der Preis ist schon eine Hausnummer aber man kommt bestimmt öffter als 4 x damit hin (lange Haare) Am Anfang riecht es etwas chemisch aber nach dem Glätten ist der Geruch so gut wie weg. Ich finde es jetzt nicht penetrant sondern eher angenehm und auch dem feuchten, nassem Wetter bleibt meine Krause Glatt! Alles in Allem bin ich begeistert.

Time consuming to use, but if directions followed correctly gives great results.

I was skeptical at first that this would either damage my hair or not do anything. I was pleasantly surprised when it worked super well - almost too well. My hair was very straight and absolutely no frizz. I did the damaged hair application too - and my hair feels healthy after use. 2 months later and I still have great result but finally getting a little bit of texture back. I rated 4 stars only because it made my hair a bit flat and too straight for my preference; however this could be the absolute goal of someone else. I would purchase again if I wanted nice straight and no frizz hair at an affordable price.

I recently used this product on my mom’s hair, as she had damaged, frizzy and curly hair and I am absolutely thrilled with the results. Her hair looks smoother, shinier, straighter, and healthier than ever before. The application process was straightforward and easy to follow, however it took me almost 6 hours to complete the whole process 😯I was dying of flat ironing on her hair, lol !! The product had a pleasant scent and did not cause any irritation for me and her. After the treatment, my mom’s hair was noticeably more manageable, frizz-free, and beautifully straight. It has 2 weeks since we applied it, and the results are still impressive. I highly recommend this Hair Keratin Treatment to anyone looking to revitalize and straighten their hair. But I believe it’s not a good idea to do it yourself specially if you have a long and thick hair cause it might take forever and you can’t flat iron the back of your head very easily!! It’s better to ask a friend to do it for you and it’s very time consuming!!

I used this product yesterday and after the final wash my hair looks great. I went from damaged wavy hair to straight heavy and healthy hair. The best part is that after the final wash, I didn’t have to spend an hour blow drying my hair with a round brush. Just used a hair dryer and a regular brush and the result was great. I’m not sure how long it will last, but I think I’ll add this to my hair routine.
