Size: 4PC EXTRA STRENGTH
I’ve used this product twice and the results are incredible. My hair is much smoother, shinier, and easier to manage. The treatment really helps eliminate frizz and leaves my hair looking healthy and strong. I love that it’s formaldehyde-free and doesn’t contain parabens. The argan oil makes a big difference in moisture and shine. The set includes everything you need: clarifying shampoo, keratin treatment, moisturizing shampoo, and conditioner. It’s easy to use at home and the results last for weeks. Definitely salon-quality at a much better price!

Complex Brazilian Keratin Hair Blowout Treatment really worked for me. I purchased it several months ago and I was very skeptical to try it. I thought it would not work or that it would be difficult to do the treatment myself. I have fine, wavy hair and because I'm aging (I'm 54), there is less hair on top of my scalp now. I don't get pretty curls or waves when my hair dries naturally. I get thin frizzy waves. Going to the beach, or being in humid weather is awful. It curls up in weird ways. So, I decided to try this since I tend to do the Brazilian Blow Outs pretty regularly. I wanted to see if I could save some cash with something that worked for others. I'm really glad I tried it as it did soften and relax my hair to the point where it did not curl up weird. This product will not leave your hair stick straight though. It also contains formaldehyde which some people are concerned about. The amounts are not high enough to deregulate though. Here's what I did: I washed my hair twice with the clarifying shampoo and followed the instructions. I wore a disposable face mask and gloves. I used a brush and worked the product through my hair, one small piece at a time from root through ends (do not apply to the point where it is dripping as it will coat the hair heavily and you'll end up with oily looking hair). I followed as instructed and left it on the required length of time. IMPORTANT: Because this product contains formaldehyde and other chemicals (any liquid that straightens hair is a chemical) you will need to heat your hair in an area that is well ventilated. I used a fan to blow the fumes out of my slider window. Do this when you begin to blow-dry the hair and flat iron it. The fumes are strong and burn your eyes. Also, you will need a second mirror to see the back of your heat to ensure you are taking the bend out of the hair there (cow licks) appropriately and uniformly around that part of your head. This is very important because you do not want some of your hair flat and other parts wavy when this dries. Flat iron in the direction that you normally style and give yourself a little gentle curve where you think you normally like so it's not sticking straight at the ends. I did not flat iron the top of my hair as many times as I did the back because I have less hair there and I did want to leave some body on the top. Leave the product in once you're done. I left it in about two hours before washing because I was going out that night. I think next time I use this I will leave it on a lot longer. They recommend at least three hours or even overnight. Nice results. Not stick straight but not wavy. It's been about a month since I used it and my hair is still manageable, noticeably flatter, but there is a bit of body too. It dries much quicker too and even though I still have to flat iron a bit, it's not at the higher temperature setting. I find that 360 degrees does the trick where before it was at 400 degrees. Not good to do that high ever. I would say this product worked very well for me. It's not as strong as the Brazilian Blowout but I also don't feel that it was not effective. It was effective, and it only cost a fraction of what the Brazilian Blowout costs me. I would buy this again.

This product works really well on me, at the beginning I didn’t have any faith on this product because is a cheap product for all the things that it offers. I got a 3b curly hair and I let sit the product for two days and my hair was straight. I no longer need to use a straightener or blow-dry my hair all the time because my hair is super straight. The only bad thing about the product is that it burns the eyes but it has a nice smell. If you use the product step by step you will have straight hair.

I recently purchased the Keratin Research treatment, and I am thrilled with the results. This product has completely transformed my hair, leaving it smooth, shiny, and incredibly manageable. I am more than happy to share my positive experience and recommend it to anyone looking for a high-quality keratin treatment. First and foremost, the application process was straightforward and hassle-free. The instructions provided by Keratin Research were clear and easy to follow, allowing me to achieve professional results in the comfort of my own home. The kit contained everything I needed, including the keratin treatment and clarifying shampoo. It's worth noting that the application process does come with a strong and unpleasant odor. The scent can be quite overpowering and may cause discomfort, particularly for those with sensitivity to strong smells. Additionally, during the application, there is a possibility of the odor irritating the eyes, which can cause temporary discomfort or a burning sensation. However, it's important to remember that these effects are temporary and occur only during the application process. The odor tends to dissipate over time, and once the treatment is complete, you can enjoy the benefits of beautifully transformed hair without any lingering unpleasant smell. Moving on to the results, I was astounded by the transformation in my hair. Once I completed the treatment, I noticed an immediate improvement in the texture. Gone were the frizz and flyaways that used to plague me. My hair became remarkably soft and silky, with a noticeable reduction in overall volume. Styling my hair became a breeze, and I found that I needed less heat to achieve a sleek, polished look. The longevity of the Keratin Research treatment truly impressed me. Weeks after application, my hair retained its smoothness and shine, even in humid conditions. This long-lasting effect has saved me valuable time in my daily routine, as I no longer need to spend hours battling with my unruly hair. I can confidently say that this product has been a game-changer for me. An important aspect to consider when using the Keratin Research treatment is the time required for the application process. It's worth noting that the application can take approximately 2 hours to complete, depending on the length and thickness of your hair. While this may seem like a significant time investment, the exceptional results and long-lasting effects make it well worth it. By following the instructions meticulously and investing time during application, you can achieve optimal results and enjoy the convenience of reduced styling and maintenance time in the long run. In conclusion, Keratin Research has exceeded my expectations and delivered outstanding results. Despite the temporary strong odor and potential eye irritation during the application, the end result of beautifully transformed, smooth, and manageable hair is well worth it. If you're looking for a reliable and effective keratin treatment that provides long-lasting results, I wholeheartedly recommend giving Keratin Research a try. Embrace the process, follow the instructions carefully, and unlock the beauty of your hair with this remarkable product.
