Review: Takes some doing but saves me beauoup dollars! Well worth the time and effort. - Oh happy day! Why? Because I'm never paying $200-400 to get my hair done ever ever again. Ever. I don't have any "before" pics, and really if I did, they'd be pointless. My hair's been processed to hell and back for years. I was born with 3a,3b,and 3c-type curls all over my head at once. Soft curls at the front, tighter squiggles in the back, shrubby underneath. It's finely textured but there's a lot of it, giving the illusion that it's thick. I began doing Brazilian Blow Outs five years ago when I moved from the cool northeast to Southern Louisiana - home of the sort of humidity they write books about. New Orleans is a great city, but it's a total hair nightmare nine months of the year. Brazilian blow outs changed my life but they left me chained to a very expensive hair routine. Although an involved, lengthy procedure, the blow outs didn't seem *hard* and I often wondered whether I could do them at home. TURNS OUT I CAN! I was worried about messing it up terribly so I enlisted my husband to help with the back. "Hey honey, can you help me with my hair tomorrow? I'm gonna do the keratin at home." "The what? Well, okay, sure." "We'll need to do it outside." "Whatever." "And we should have a fan." "Mmmmhmmm." "For the burning and the runny eyes." "Sure...wait - what? Burning? What is this stuff?" After calming him down and assuring him it was perfectly safe (the jury is still out on that, though) we set up shop in the yard with a mirror, a fan, a blow dryer, a tail comb, a dye brush, a plastic straightening comb and my trusty Babyliss Nano Titanium 1.75" iron (git you one o'these because they are amazing). The clarifying shampoo might make you nervous because all signs of life and health WILL be sucked out of your hair as if by vacuum. Worry not. This is normal. Application was simple, but I do think he used too much. Aim for saturating each and every hair, but not for making your whole head drippy-wet with the stuff. Apply it in small sections, comb it through with the tail comb, and whatever comes off the comb, wipe it off. No need to completely panic if you over apply: in the end, over-applying only made Day 1 & 2 gummy and strange. Past that it was fine. You're going to want to be in a VERY well ventilated area during the blow dry/flat ironing stage. Even outdoors with a fan it was hard on the eyes and mucus membranes. If you HAVE to do this in an apartment, I suggest doing it in a room other than the bathroom because unless you have an exhaust fan it just might be the last act of your life. Set yourself up someplace where you can open a real window. If you've enlisted the help of a partner, you may have to endure listening to "OHMIGOD WHAT IS THAT SMELL?" and "There is no way that's okay. Please think of your brain cells." and "No, seriously, stop this now or I'm going inside." for however long it takes to dry your hair. The ironing was easy - I used large, wide clips to section parts off, then used the straightening comb to comb through and "hold" sections of the sections (very small sections, mind you; my sections were thin, but wide, because my iron is wide. Make section width based on whatever flatiron you have, but make 'em thin.). At first I thought the comb was unnecessary, but when you're passing a 400F iron over a small section of hair 7-9 times? It's HOT and you do not want to be guiding that hair through the iron with your hand. Buy a spring-loaded straightening comb. Worth the $5. This was stinky, eye-watering business. The fan helped. Ironing the product in was very simple with a mirror. My husband stuck around (ten feet away) but I didn't need help by that point, anyhow. The finished product this first go-round was verrrry disappointing at first. Very gummy, not slick and smooth. Very coated-feeling. I attribute this to over-application. My husband noticed, too. He kept apologizing and said "That is NOT how you look when you come home from that salon.". But after two more days of light ironing before going out - presto: it was perfect. I washed & conditioned it with the stuff that came in the box a week later and it dried super quick and ironed like a breeze. It's got great body, too. I would recommend this product to anyone who has already experienced a professional keratin/Brazilian Blow Out treatment at some point. At least that way you'll know how your hair will behave and you'll have an idea of what to expect. Anyone going into this expecting to have pin-straight hair after washing without having to either blow-dry, flat iron or both should turn right around and buy a traditional straightening product. That's not what this is. You still have to put some work into getting your hair straight, just *a lot* less work than without the treatment at all. This stuff will knock out frizz and leave your hair smooth and silky. It will loosen curls considerably for the first couple of weeks, but as the products wears off, your curls will return. TLDR: Even with our mistake of over-applying I'll still likely get two more applications out of this $79 bottle. Three trips to the salon for the same treatment would cost between $600-800. Absolutely worth a few hours of my time and effort, and worth a little eye-burning. ;)
Review: This Product Worked Well For My Type of Hair - 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.

## Questions & Answers

**Q: Any good brand name of durable flat iron Pls? there are so many out there but don't know how to purchase the right one? any help  or advice Thnx**
A: GHD

**Q: Can the leftover KHT be used for a future treatment?**
A: Yes, you can...mine had enough treatment for 4 different times...you will not regret it... I had many compliments..

**Q: can this be applied on top of other keratin treatments? I last did my daughters hair 4 months ago with Kerasilk keratin treatment.**
A: I'm a not a professional hair dresser by any means. I just like saving money.  I had previously done my hair at a salon and they used a different treatment. I could tell because it smelled different and it was very flaky when they dried it.  I used Complex Brazilian Global and my hair turned out gorgeous.  You just have to make sure you blow dry it VERY straight, like they do in the salon and also seal it with the hair straightener.  Good luck!

**Q: Can I put my hair up within the three days I leave it in?**
A: You shouldn't because it will leave the lines in your hair. Try to keep it as straight as possible I straightened my hair everyday to keep it perfect.

*by N***K on November 23, 2021*

I have only met one other person with the hair dilemma that I have endured since I was a little girl, and that person is my child. I have a LOOOOOOT of hair per square inch, however each strand is unbelievably fine. I have tried everything anyone can possibly recommend to subdue the knots and I get no results. I had a relaxer once - caused my hair to be unbelievably dry and while it looked great after leaving the salon, maintenance was almost as difficult as it was before the relaxer. I also had lots of breakage on the end, regardless to how gently I combed/brushed. I had to resort to leaving my hair in a bun or a long braid most days, out of fear of losing a lot of hair from knotting. Even with a relaxer, I was always gentle and avoided a lot of heat. I would do roller sets and it would take at minimum 4 hours to dry. YES, FOUR HOURS even with the coke-a-cola sized rollers. Salon visits - Not always fun if my regular stylist was not available, as people see volume and assume that they can just rip through my hair. I think the impression most people get is that a lot of hair is the same as have thick strands. I have lost count as to how many professional stylists I have to educate. I have even had to BEG to have my wet hair comb with extreme care, as my delicate strands tend to snap due to harsh treatment. I decided to throw caution to the wind, as I have a crazy schedule and spending an entire day on my hair isn't option, OR fun. I understand the risks associated with formaldehyde, I went outside to blow dry my hair, reducing exposure to fumes. It did not take nearly as long as I imagined to do my hair, even at nearly waist length. I left the product in for 3 days, because despite not taking long, I still like to minimize heat. Although my hair is fine, I opted flat-iron on 450, but I only passed over each section 3-5 times max and my hair was left SUPER straight, shiny and silky. Today, I washed it using my own paraben free shampoo and applied CHI 44 Iron Guard as I put rollers in my hair. My biggest shock was how easy my hair was to manage. Honestly, that alone was worth it for me. Can you imagine being afraid to wear your hair down all the time, or having to get in the shower for a least an hour to attempt to work through knots??? The comb and Wet brush just slid through my tresses with barely any shedding AT ALL! I am sitting under my hair dryer now with giant rollers in my hair. Now, I do have a commercial hair dryer. I spend a lot of my hair tools, but I typically get salon results. I anticipate that my hair will be just as shiny as it was the other day. I'll update after a couple of months, but as of today, this product is a complete win for me.
