impressed with the results
I recently tried the Amazonliss Keratin Hair Straightening Treatment at home, and I’m genuinely impressed with the results. The three-step system is easy to follow, and the instructions are very clear — especially if you’ve done smoothing treatments before. After completing the full process, my hair looked noticeably smoother, softer, and much easier to manage. The frizz was reduced significantly, and the shine was beautiful without feeling heavy or greasy. What I love the most is that the formula feels gentle and doesn’t have a strong chemical smell, which makes the application much more comfortable. It’s been a few weeks, and my hair still feels silky and stays straight for much longer, even in humidity. For an at-home treatment, this kit delivers salon-like results at a great price. I would definitely repurchase and recommend it to anyone wanting smoother, more manageable hair.

LOVE THIS PRODUCT
Awesome, awesome, awesome product. Let me start off by saying that this is my first keratin smoothing treatment, either at home or professionally. I'm a total weirdo with researching products before I buy them and kind of a home beauty junkie. I probably invested a good 2 hours scouring the internet making sure that I was getting the best deal and the best product. I'm extremely happy that I ended up ordering this!!!! I have hair that has been badly damaged by years of bleaching, dying, straightening, and other heat application. I recently made the decision to try to go almost completely heat and bleach free and to wash my hair less so that I can give it time to heal and grow properly. Before I started using this product, I had been setting my hair every few days with curlformers (overnight curlers that work wonders.. you should check those out too) to smooth out my hair and give it a style that worked professionally. Left alone, my hair is frizzy, poofy, and wavy.. just kind of a goofy texture. I will link pictures for the before and after. (It had been set in braids or something in the before one but is still a pretty accurate representation. I couldn't find an unaltered before one because I never took pictures with it without fixing it). The actual processing of the product wasn't a walk in the park, but was nothing impossible. Takes a little over an hour, with directions included in the kit. They give you a clarifying shampoo, the actual straightening product (the bread and butter of the product), and a mask. I used a regular shampoo before the clarifying shampoo (washed it twice). The worst part about it was the fumes during the actual straightening process. You may want to use an older or backup straightener if you have one, though I did not notice any residue on mine. Make sure that you do this in a large room (I ended up moving from my small bathroom to my larger bathroom) so that the fumes are less of an issue. I ended up closing the eye on the side of the head where I was straightening. Goggles probably wouldn't be a bad idea. I would also recommend not having kids or pets in the room if you have any of those. It is definitely unpleasant, but if you get that smell you will know that you are doing it correctly. I then used the mask and then my regular conditioning treatment. I could feel my hair sitting flatter in the shower. I let it air dry so that I could see the full results. They were great! It looked better than if I had straightened it, and my hair is so shiny. It also helps your hair to lay better with extensions if you use those. However, I would not recommend using this if you like the look of big hair all of the time. It might smooth it out too much for you. Anyway, it's been about two weeks since I've used it and the results are still about the same. I'm going to try to hold out as long as I can before I use it again because I don't like the idea of the iron that hot on my hair, but it definitely beats having to straighten it every day, so it saves your hair in the long run. You might have to do a few touch up spots in the morning if you like it super straight, but that's it. I'm not sure why more people do not use this product!! Saving me money in the long run, and a huge chunk of my morning. Hope you like it! I have not been paid or received a discount for writing this review, just really liked it and wanted to share. Last thing, the company originally sent me the smaller bottles that sell for 55 on here (1.4 oz?) I messaged them and they were very nice. They let me keep the smaller ones, as well as overnighting the bigger ones the next day. Just make sure that they send you the right size (big bottles about the size of normal shampoo and conditioner). :) EDIT: one month later and still no damage. Hair is still pretty straight.. I might touch it up soon.

I can’t stand the smell!
It kind of works, emphasis on “kinda.” If you have straight or wavy hair that’s a little frizzy, I’d say give it a try, you’ll probably like the results, but if you have curly hair, not so much. My hair is a little less frizzy, there’s no denying that, but, by no means is it straight and silky smooth with no frizz. If you want this to be your styling routine, you might be disappointed. Chances are, you will still have to style your hair every time you wash it, which is exactly what I’m trying to avoid. In other words, your hair probably won’t look good enough to skip blow drying it, straightening it, or whatever you currently do. The biggest difference for me, as far as the before and after, is that now my hair doesn’t hold a curl at all, which is not what I was after. Obviously your results will depend/vary based on your expectations. The dealbreaker for me (the reason for the 1 star) is that I couldn’t stand the smell. I had to do one little section and walk away from the product. I imagine (not exaggerating) this is what drinking bleach would feel like. My throat and nose were a mess, and my eyes were blood shot. I was applying it with my COVID-19 mask. I had to take 3 painkillers to get rid of the headache I got from it. All in all, the product “does” work (to a certain extent). It does some of what it claims to do, which is improve frizz, but it doesn’t eliminate it completely. I think that as long as you don’t expect perfectly flawless, pin straight, zero frizz hair, you’ll be fine. Update. It’s been over 4 months since I put this on my hair, I’ve tried again and again, and still haven’t been able to get my curls to come back. I’ve always curly hair, and I don’t mean wavy, not kinky or coily type 4 curls, but actual wringers, and now, all I can get is a very loose, barely there S shape wave. We obviously won’t all get the same results, you might love this stuff, but losing your curls could be a risk you’re taking. I just cut 10 inches off my hair hoping that would would help my curls, but it didn’t. Just something to keep in mind...I uploaded before and after pictures for reference.

Would definitely buy again!
Really happy with this keratin treatment! I used it at home and my hair feels so much smoother and softer. Frizz is noticeably reduced, and my hair looks shinier and more healthy. The process was easy to follow, and the results were visible right after. My hair is easier to style and feels much more manageable. Great at-home option if you want smooth, salon-like hair. Would definitely buy again!

Nous sommes en test avec tous les produits Amazone de lissage à la kératine. Celui-ci nous a agréablement surpris ! L’odeur est incroyable, il sent la gomme balloune alors ⭐️. Nous ne l’avons pas rincé immédiatement comme le protocole le suggère, nous avons attendu 48h de + et replaqué les chvx entre temps. Le résultat séché à l’air est vraiment bien, sur cheveux naturels, wavy et fins. Nous allons l’essayer sur des chvx plus corsés prochainement alors 🤞🏼

The result is not magic for this first treatment but I can see that my hair is smoother and easier to style, I could also see a reduction in volume. Indeed, it is necessary to apply the product in a well ventilated room to avoid being indisposed by the fumes. My hair was not damaged at all so I cannot comment on the repairing effect of the keratin. I have been doing henna (100% natural) for over a year. I did a lot of research before doing this treatment because I was afraid of hair breakage. So with my natural henna, no damage, no breakage but it may have made the keratin treatment less effective. Overall I am satisfied! I took the 250 ml pack and I will do the treatment again in 3 months. The only thing that could be improved would be to seal the large bottles.

I have curly/wavy frizzy hair & it helps tame my hair its not perfectly straight since i do it myself its a long proccess and loose patience but it works wonders my hair is 87% straight and it lasts couple months. It does smell very strong it hurts the lungs so wear a mask + gloves and keep the fan on or do it outside if possible. I can finally leave the house without styling and damaging my hair with heat
