Keratin Research Keratin Brazilian Keratin Hair Blowout Treatment Extra Strength, 120ml, for Curly Hair, Enhanced Formula with Moroccan Argan Oil and Queratina Brasilera Tratamiento Forte

I'm amazed at this product and disappointed I didn't find it sooner.I am half asian half caucasion and have naturally 2A/2B frizzy hair. My hair is dyed brown from black, so the damage makes it course and frizzy as well. I followed the salon directions to a T and I now have stick straight, silky, healthy, and bouncy hair that dries in half the time as it did before. The only thing I did differently than what the directions said was substitute the shampoo and conditioner for a sulfate and sodium chloride free set by PUREnature. I had a Brazillian blowout once, when I was in my early 20's and this gave a much nicer result for way cheaper.TIPS:Application- I applied using a brush and sections and used gloves. The next time I do it, I will apply less product. I used about 1/3 of the 120 mL bottle and the hair only needs to be combed through with enough product. There should not be product dripping off the ends. My hair is also 20" so a little goes a long way.Fumes- They are seriously strong and made my eyes water. Like others, I used the vent fan in my bathroom and kept my apartment windows/balcony door open. If you plan on doing this it might be wise to purchase a pair of safety goggles.Drying - I used my Revlon One-Step Hair Dryer and Volumizer and could not imagine doing it again without it. It help speed up the drying process while keeping the hair detangled.Straightening- I recommed using a good quality straightener that heats evenly to the desired temperature mentioned in the instructions. I had to borrow one from my mom and will be looking into getting a better one down the road because it didn't clamp or heat evenly so it made it difficult to get all of the fumes out. I straightened my hair for 3 hours after drying, using very thin (almost see through) sections. I also applied a heat protectant and let it sit 10 minutes beforehand because it started smelling like burnt hair and I saw tutorials on youtube where they used a heat protectant. I also took the opportunity to apply jojoba oil on the ends and have that heated into the follicle as well (jojoba is most similar to the molecule size of natural hair oil). After most of the fumes/product was out of my hair (you can feel the difference where there is product that still needs straightened out), I kept it in for the recommended 72 hours, straightening when I didn't have anything else to do at home. When I do this again, I will definitely avoid placing product directly on the scalp because you can feel it and it is not fun to sit with for 3 whole days.TLDR; this stuff works if you follow the directions well. Great investment for the price and avoiding the hassel of styling/drying hair. Going to save a bunch of time=money for the next 5 months. For $55 (including the shampoo and conditioner I purchased separately) completely worth it! Very satisfied.

I have been using Keratin Research treatments every 4-6 months for the past two years and was very happy with the results. I never thought I would find anything better, but decided to take a chance with the Keratin Forte Plus. It was the best decision I could have made because the results were beyond my expectations. The application process is the same, with the difference that I left it on for 3 days, instead of just overnight. Yes, the smell is stronger and had to stand in front of a box fan to help avoid the fumes while passing the flat iron (which I usually complete in 1 to 1.5 hours because I have lots of hair and very long). However, after washing my hair the 3rd day I noticed my hair is now very straight without having to use a blow dryer or hair straightener. My hair is naturally wavy (not curly), but gets very frizzy in humid areas, black with blonde highlights and the treatment did not cause any damage; quite contrary it now feels very soft. I suggest purchasing the small bottle and not the large (even if it saves you money). For some reason, once it is opened and use the remaining product for a 2nd or 3rd treatment, the results are not as good. It is best to use the small bottle, once. The 120 ml was enough for one treatment on my 20 inch long hair. I would highly recommend this product to anyone who has the patience to apply the treatment at home and flat iron their hair in small sections. It is definitely worth it and saves you paying hundreds of dollars at the salons!!! Best of luck and I am happy to answer any questions.

I have no idea how people used this bottle multiple times. I have thick, long hair and I ran out of formula. I think I oversaturated it a bit, but it definitely wouldn't be enough for 2 applications for me.The instructions are a bit confusing. But make sure you block out 2-3 hours to apply this and straighten your hair and wash it out and straighten it again. Takes forever, especially if you have long, thick hair.My hair felt so disgusting after I applied the solution, like super greasy and dirty. My scalp was also a little tingly some places. I thought for sure I was going to need to rinse it out before 72 hours. The smell was also really strong and kept me up all night with a headache. But after the first day it felt a lot better and didn't smell like chemicals as much.After washing my hair, I could tell how well it worked immediately. My hair was silky smooth and easy to manage. It doesn't straighten your hair, but makes it much easier to dry and manage. I can comb my hair out when it's wet and it dries pretty straight, or I can leave it wavy if I want.My advice would be don't do it at night before bed and make sure you have plenty of ventilation, like a fan and an open window. Overall this is a great value.

I've been doing keratin treatments for several years, both at salons and at home. I have been disappointed with recent treatments at salons because they are now using the treatments that have low or no formaldehyde and they wash out the solution before they flat iron. These treatments were a waste of my money. Didn't last a month.I really like this product because it works of you follow the directions, and they send you an instructional email ahead of the delivery and written instructions with the treatment. It does have a lot of formaldehyde but you really need it if you want the treatment to last, so you MUST ventilate while applying and flat ironing. And flat iron on small sections at a time as described in the instructions. Trying to do large sections means you won't heat all the hair enough to seal in the treatment. So make sure you have time to do the flat ironing correctly.My natural hair is fairly fine, curly and frizzy. My hair looks great again, very little wave left and smooth as silk.One more thing, I recommend using a heat resistant glove while flat ironing.
