  • Miracle Treatment
Size: 4 Piece Set
I’ll start with saying this product is absolutely amazing! I usually get my hair chemically straightened in a salon (the Japanese straightening not a Brazilian blowout- I think those are horrible for your hair-it just dried mine out & created a frizzy disaster). This service generally costs me $1000+ last time being about $1300. My hair is VERY long (37in), about half way down my bum and EXTREMELY thick, wavy with some ringlets & depending on it’s mood, frizzy. With that being said- my hair is also very healthy and I try to take good care of it; doing masks once a week, deep conditioning it every time I wash (you can do this by just leaving your regular conditioner in for at least 10-15min). I regularly do keratin treatments & use Pureology shampoo & conditioner along with their other products & mix in Olaplex hair perfect No.3 once-twice a week. Having a love/hate relationship with this current length, taming it was a necessity making it at least manageable. If you've ever had your hair chemically straightened you know they price by length and last time I went my hair was about half way down my back so with it being this long I dreaded to think of how much they’d charge now. I began the unlikely search for an alternative to the salon with my hopes set at something that would possibly give me a slightly similar result or at least calm it down. Upon finding this product I saw other reviews that looked promising even though none of the hair types in the photos posted matched my wild locks, still, I decided to take a chance. So stoked I did. It beyond exceeded my expectations. Today was the first day I washed the product out of my hair after nearly four days instead of just the suggested three and my hair dried exactly as straight as it would have from an overpriced treatment (natural dry as well no blow dryer etc). The only thing the instructions don’t have, is, each time I got mine done at the salon, the dresser would do a painstakingly longgg perfect straighten; doing hair strips that were about the width of a nickel. It’s extremely important to have your hair this finely straightened because that’s the “standard” you're setting for the product (I know that’s not very technical but it’s gets the point across lol). My hair feels amazing- it didn’t dry it out, didn’t cause any to fall out (which was a huge concern of mine) in short it did absolutely no damage just worked wonders. For perspective on the amount of product, you know how long my hair is, (bare with me here) I don’t have dainty hands by any means I can almost palm a basketball lol and it takes two large palm fulls of shampoo and conditioner each time I wash my hair. The bottles in this product are a good size, but I was still skeptical if I should have gotten two but one box worked just fine and there was JUST enough of the keratin straightening product to have my hair perfectly saturated. So to those with shorter hair you’ll really be getting your dollars worth gettin two treatments (maybe more) out of this. Now let’s see how long it lasts, either way I’m happy. I will absolutely be using this method from here on out. -Follow up: it’s now been nearly two months since I used this product; my hair has a little wave back to it but for the most part is still very straight and silky smooth. Happy customer. Absolutely recommend. Also to those who are have skin irritation etc... like with anything you use on your skin- check the ingredients label and for the love of god do a small test patch on your skin! ... show more

  • FINALLY A HAIR PRODUCT THAT WORKS! (Sorry for shouting, it REALLY works!)
Size: 4 Piece Set
The closest to a life-changing hair product as I have ever found, and I have tried too many to count, wasted hundreds, probably thousands, of dollars. I saw something about a keratin treatment on pinterest and looked this up on amazon. Checked out reviews, figured even if it didnt work, which I kind of expected, it was at least a minor investment, and I wouldnt have to waste any more time wondering if this one did work.... It worked soooooo well! I am caucasian with thick, wavy, not smooth, frizzy, unmanagable, hard to dry, hard to style hair. Air drying leaves me with frizz, my waves are frizzy and irregular, I have tried every product to enhance waves/reduce frizz, all attempts leave me looking like I just escaped from an institution. There is no just blow drying to style it, I cannot hold enough tension with a brush to smooth it, blow drying dries my hair, but it looks like a straw broom. So after blow drying, I have to heat style to smooth, with either a flat iron, curling iron, or instyler (highly recommend the instyler, by the way). So I went through the process of applying and ironing repeatedly. I found the initial application of the product to have the worst of the fumes, rather than the ironing portion. Waited three miserable days before washing, reironing my hair each day as kinks develop in my hair overnight. I say the days were miserable because the solution leaves a waxy coating on the hair. My hair felt dirty. Friends kindly said it did look fine, however. It was at least passable in public. Finally, the happy moment of being able to wash it out... And my hair was glossy! I could air dry it! My wave pattern is still....not good, but I could go out in public with NO heat styling at all. I could just blow dry it, and not have to heat style with anything else. This is major for me. So much less time consuming. It also dries faster. For the first couple days I almost felt it was too glossy (as if that is possible). The initial glossiness toned down to normal and infinitely more manageable, normal texture. Despite the excessive passes with a flat iron, I have not found this product to actually straighten my waves, which are intact in their original wave pattern, oh well. I dont know if this is just due to my hairs thickness. Other people report straightening. For me it seems to fill in the porosity of the hair structure, making it smoother, shinier, easier to dry, faster to style, cutting so much time from my routine and making things like swimming in public and getting my hair wet something I can actually do! And not feel horrified. This is the set I initially bought, there was enough of the keratin treatment for only one treatment with a little left over. After this I bought a bulk size, with enough for probably several years of treatments for about $100. I have repeated treatments two more times so far, and will probably keep using this stuff forever. There is a slow washing away of the keratin, and after about 3 months I am ready to go through the process again. I did try not waiting the three days once, waiting instead just one day to wash it out, but I do think the effectiveness was lessened. I have plenty of clarifying shampoo from the original kit, but I will use dishsoap when I run out. It seems the more porous, damaged, and roughed up your hair is, the better the keratin is able to bond to it. I have never used the shampoo/conditioner from this kit, but I definitely use sulfate free shampoo to slow the washing off of the keratin. I will be doing another treatment this monday, and will stay home as much as possible during the three day wait till shampoo time. I get excited just thinking about the fresh shine and smoothness! I wont go into the questionable health issues regarding the treatment. But I would as with all things recommend educating yourself before making a decision for yourself in that regard. I hope my somewhat lengthy review helps someone! I appreciated the reviews left by everyone else when making the decision to purchase this! ... show more

  • Straight Hair in 90% humity
Size: 4 Piece Set
Absolutely loved this product and will buy again when time to redo my hair. Leave hair silky smooth and straight. I have really curly frizzy hair and only need a slight flat iron every morning after using this product. Whereas before using 5 mins after intense flatiron my hair would revert back to a major frizz ball. As for the smell I had no issues at all, with no burning effect either. ... show more
