Smooth and shiny results
Leaves hair soft, smooth, and much less frizzy. Easy to apply and gives a noticeable shine after use. Great option for at-home keratin treatment.

Love the End Result
I am not much for writing reviews, but since I rely on reviews when I am trying to decide whether to buy something or not, I thought I would provide my experience with this product which I used for the first time today. Now, my hair is frizzy, kinky curly and definitely hard to management, especially in Florida's heat and humidity. I think in my life time (I'm 56) I have had more bad hair days than good. So, I am no stranger to methods of straightening my hair. I had my first keratin treatment several years ago and before that I had the Japanese Hair Straightening which has its own drawbacks, but shelling out $250 or more on any regular basis is just not in the budget. Previously, I was using Bio Ionic Agave Smoothing System. It is the same process, washing with clarifying shampoo, blow drying hair, putting on the treatment, leaving it on for 30 minutes, blow drying it in, and then flat ironing it. Then you need to let the hair cool for about 20 minutes, and then you need to shampoo hair again (with a sulfate free shampoo), condition and blow dry and flat iron hair again. Plus, if you had hair color in your hair, this product does lighten it quite a bit, and if you wanted to color your hair you have to do it right after the last step, otherwise you needed to wait a week. Needless to say I would spend a lot of time doing this, and the end result was just okay. The Agave product had a caramel scent to it, and you did not need a mask while applying it or anything, but the scent kind of stayed with you and that part I did not like. So, after using the Agave for over 3 years I wanted to try something else. So, I started to look for another product and of course I came to Amazon to start my search. After reading the other reviews, I decided to give this a try. I was a little nervous at first because I think this product is stronger than what I was using previously. I read where people wrote that it made their eyes water and to make sure to do this procedure in a well ventilated area. The problem is that I live in a really small apartment that does not have good air flow. I turned on all the ceiling fans and the bathroom fan along with a stand up fan that I had. When I needed to blow dry the product into my hair, I sat by the sliding glass door with the fan blowing on me so the fumes would go outside. This product did make my eyes water and I am not used to wearing a face mask, so I did have a little bit of a problem with that, but I was able to get through it rather quickly. When it was time to flat iron my hair, I did it by the door as well and overall there did not seem to be a lot of fumes. I am not sure if this was because I was mindful of the amount of the product I had put in my hair, or I just did not notice it. I bought the smaller bottle (4 ounces) just in case I did not like it, and only used 2 ounces for my shoulder length hair. The first thing I really loved about this product is that it did not strip my hair color so compared to the product I was using previously. Since the it had extra steps that needed to be done, I would easily spend 4 hours with the whole process. With this keratin treatment, it took me only about 2 hours. This product left my hair really smooth, and I have not noticed any type of scent. I liked the idea that I could wash it relatively quickly after the treatment, and I thought that I would be washing my tomorrow, but I did not feel that it will be necessary. The only thing I would suggest is that if you have never had a keratin treatment before and want to try doing one on your own, to have someone with you to help you with the process.

Worth the effort.
This product works great to eliminate frizzy hair. My hair type is 3b, left on for a little over 24 hours. Frizz gone. Easy to blow dry and straighten. Or let it dry and have soft curls. The smell is strong. Use a fan to blow the smell away from your face. Worth the price verses $300 for keratin treatment or Brazilian blowout. Lasts about 3 months, washing 2-3 times a week. Good luck!

THIS WORKS!!!
It really does work!! I have tried every type of treatment out there and my hair is so unresponsive. I've tried relaxers, I've tried perms with big curlers to soften the curl, I even got a brazilian hair treatment in the salon that did NOTHING. And let me tell you, I have very stubborn hair. I have 3B type curls and have always struggled to control it and make it pretty. My hair is coarse and fine and 50% frizz and the curls aren't uniform so it's not a good look. It takes an hour to straighten it and once it's straight it's so stiff that it doesn't look natural. I chose this product because it had such a high rating and because it seemed to be legit. I was very suspicious of all the products I looked at because even though they used so fancy name brand product on my hair at the salon it obviously wasn't strong enough to work on my hair (it did work on my cousin's wavy hair though, and took out almost all the frizz, my hair is just stubborn!!) Also, I didn't want to spend a ton of money on something that might not work so I picked this because it was a trial size. I only used about half of it so there's enough left over for another go around, it's awesome! I didn't even follow the directions and it still worked wonderfully. Let me tell you what I did: I didn't use a clarifying shampoo because I didn't want to go buy one, I just washed my hair really thoroughly and scrubbed at my scalp really good to clear away any dead skin or product. Then I rinsed my hair really well to best get rid of any soap residue. I blew it dry (a terrifying sight for my fiance!) and started to apply the product. WHEW the chemicals are strong. I would recommend doing it in a well ventilated room if at all possible because I kept having to stick my head out of the bathroom so my eyes would stop burning. I was not delicate about the application, I ended up putting too much in and my hair was def over-saturated but that's what I wanted! I let it sit in my hair for thirty minutes while I surfed the internet. I then took a fine comb and combed through my whole head getting rid of the excess product. The directions say to immediately start straightening on soaking wet hair and to me that just felt wrong and like I was going to burn my hair. So what I actually did was blow my hair dry again and THEN I straightened it. I took extra time on each section to make sure I sealed the product into my hair. It probably took an hour but obviously it was worth it. Then the gross part is that your hair is stiff and sort of greasy from the product and you can't do anything about it. You're not supposed to pull your hair back, you just have to leave it straight and down and looking yucky. The directions said to leave it in for 72 hours for very curly hair, but I had to shower after 24 hours because I had to go to work. So for the first three days I didn't shampoo it, just rinsed it and used a little conditioner, which I hardly even needed cause it worked so well. My roots are straight which is a HUGE deal as that is usually the curliest part of my hair. There is still a good amount of curl to it (because the directions say "for very curly hair leave product in for 72 hours" and I only left it in for 24 hours) at the bottom but it's pretty and manageable. The biggest difference is that there is practically ZERO frizz and the hair is SO soft. It actually looks so much healthier than before I did the treatment. I'M SO HAPPY WITH THE RESULTS! As I have half the bottle left, I will probably try again in 3 months or so and I will leave it in for longer to see if that affects the curl. I really don't feel comfortable with flat ironing soaking wet hair like the instructions tell you to but maybe someone else can let me know how it went for them and I will give it a try. I really think if I had followed the instructions to a t that my hair would have come out beautiful and straight. No regrets, I still love the results!
Q**A
This treatment worked exactly how I wanted it to and I’m very impressed with the results. I would definitely say the process is pretty challenging because the fumes released by the product itself are really strong and apparently very bad for you so I would definitely recommend doing the treatment Nearby an open window. I did it beside an open screen door in my basement. Also, don’t do it in an area that your family will be in often because it leaves a fog of smoke in the area until it is well ventilated so I did this in my basement beside my screen patio door with it open And had to step outside multiple times throughout the process and then left the screen door open overnight to let the area clear and it was fine by the morning, make sure fog doesn’t go through your whole house because it is hazardous to be in injesting for a long period of time. Before: I had tight for a 3C curls which were very pretty but very hard to manage. I’ll get compliments on my hair a lot, but I didn’t really like the state especially going into summer because it was hard to manage as I said, I would have to put a lot of product in it and wash my hair almost every day I wouldn’t be able to sleep on it or I would wake up and it would look very bad so I would have to Basically wash my hair every day to make it look good and if my hair got wet, it would frizz up a lot, especially in her humidity so I wanted to do this treatment for the summertime so I could feel comfortable wearing my hair down without having to worry about it frizzing up, especially going into pools or into the lake at my cottage and not having to straighten it or put it in braids After: the treatment left me with waves or loose curls, which is what I desired, and when I got out of the shower, it was much much less frizzy than it typically is when I get out all I had to put in was some light products. I was a bit concerned because when I brushed my hair and didn’t go into curls like it typically does. It just went straight, but as long as you scrunch in all the products that you use it leaves your hair like how the after picture is. I wore it to a festival down last night and it looked at the whole time I slept on it and I woke up and it still looks good. The photos from after I woke up. I would definitely say the straightening was pretty much the same as it normally is, but I washed out the product 12 hours after straightening I put around 7 to 10 passes on each section And blow dried it with my revlon blow dryer and so yeah, I left it in overnight and for a couple hours, so 12 hours in total and then washed it out and I really enjoyed the results. I would recommend for girls with curly hair that want it to be more manageable and just know that it won’t leave your hair permanently straight and the treatment only lasts for 3 to 4 months, which is perfect for me And it might not be ideal for you so don’t go in to the treatment expecting to leave you with permanently straight hair because that’s not what it does.

Ive ordered this product twice now and I love the results - the instructions are so detailed and explain everything. This product has made my hair grow sooooo long and the straightening/ smoothing is one of the best outcomes. only downside is that when im straightening my hair my hair is super sticky and oily feeling - not sure if this is because i use too much product but i have to wash my hair before I go out in public after the treatment. Also the fumes are pretty strong, makes your eyes water and hard to breathe ( probably not good for your health) but i just opened a window and it helped with the burning. Small price to pay for amazing hair - i never thought my hair would ever be this full, long and thick - highly recommend this product. My natural hair was wavey/ frizzy and if I let dry naturally I had soft curls.
