Works great
I have been getting Keratin treatments at the Lasio Keratin Lounge in NYC for a couple of years now and unfortunately they had to close due to Covid-19. Desperate times call for desperate measures so I ordered this One Day formula bottle here (from seller Czbrm) to try to DIY. First of all I received an authentic bottle of the formula from the seller, complete with the holographic sticker. I proceeded by following the exact procedure as the salon, which is to 1) shampoo hair clean 2) blow dry completely dry 3) took a before picture which I have included here 4) put the formula in a spray bottle and carefully applied to hair from the base of head and working my way up ensuring total coverage of every single strand of hair 5) blow drying hair again 6) meticulously flat ironing every strand of hair and voila 7) took an after pic which I have also attached. It worked exactly like at the salon with a professional except I didn’t have to pay $400 bucks for a single visit like I had been up until now. It took me about 2 hours since I have a lot of middle eastern hair and now I’m going to save thousands of dollars going forward thanks to this one bottle! Hallelujah my hair is silky, shiny and frizz free. Now, this stuff has formaldehyde so it’s important to wear a mask (which we all now have) and be by an open window when you are blow drying and flat ironing to allow the fumes out and proper ventilation. For good measure I also brought my air purifier to the area I was doing my hair. I can’t tell you how ecstatic I am over how much money I am saving now that I can do this at home. For all my long hair I only used about 1/10th of the bottle for this one treatment, which means the $150 bottle should last a couple of years. Having good hair should not have to cost so much, and now thankfully it won’t for me.

Love this product
I’ve been using Keritin since we were able to buy it on-line, first Coppola’s then another brand, this is my favorite. This keratin goes on so easily I can use less and it takes less time to hot iron. For the past year I started using it different than the label. I don’t have time to wash//dry first. Every time I wash and condition my hair, I take a teaspoon or so at a time into the palm of my hand. I put my head down, flip my hair over and start by rubbing into the underside. Then another teaspoon into the rest of my hair. Ends/Bangs/close to my scalp. My hair is barely shoulder length and thin so it doesn’t take much, sometimes I use a little more. I wait as long as possible, sometimes as little as 10 min, longer if I’m watching TV. Then I blow dry and hot iron as usual My hair looks fantastic every time I wash it. Which is only every 5-7 days. My hair is always soft, shiny, frizz free. The label wash/dry with no conditioner then sit for 30 min, dry again then hot iron - it wasn’t getting done because it took too long. I’ve not had any issues putting a little keratin on my shampood/conditioned hair. My hair is healthy after a year of doing this. Just a suggestion for a quick way to look good Thanks

Excellent results, very easy to use.
UPDATE FROM MY FIRST REVIEW: It's now been about 1 year, between my sister and myself using it it's officially finished! I did mine maybe once every 3 months or so, my sister a little more often than that. I'm going to be buying another bottle. I got my money's worth that's for sure! This product is amazing! First time using this brand, I had been faithfully using another one that costed me double this cost but over the years sadly they had changed the formulation...which usually means they reduced the formaldehyde levels. So the results I had been getting was just OK. Users be aware formaldehyde is the ONLY way to get the keratin to bond to your hair, keratin treatments that have minimal amounts or use other aldehydes to compound it you'll just get passable results. Formaldehyde is also in so many other things you don't realize so don't be so afraid of it. Back to my results: My hair is very long and thick/wavy (should have taken pictures sorry!) Things you should have on hand if this is your first time using keratin: gloves, keep some paper towels handy bc I found it to be a bit messy. Some of the product ended up dripping on to my floor. Be in a well ventilated area. Get a spray bottle or better yet take the top off of a spray bottle and just screw it on to the lasio bottle..that's what I did. Applying: I did it the lazy person way...which worked fine for me: 1. Washed my hair and let it air dry, Saves time and energy. 2. Parted into 3 sections 3. Full on lazy mode: sprayed all over in each section and combed through .....maybe 5 mins total it took me. 4. Super lazy mode: didn't even bother blow drying, I let it air dry..which surprisingly didn't take long. 5. Flat ironed at 450- now that is the part where you need to make sure you're doing it properly, also be careful of the fumes. RESULTS: EXCELLENT! I'm very very happy. My hair looks shiny and feels very soft. It doesn't feel like I have any residue in it at all. And there's no strong odor from the keratin. My sister since stole my bottle and did it herself as well...lazy version too. I think this bottle will last us a good 1.5-2 years. Considering you end up using very little to begin with. Be aware that this is more like a liquid and not a cream like other keratin products so when you're applying be careful with all the spraying that stuff can end up all over the place but once you get the hang of it it's easier. Took me a long time to give this a try bc I had been using another brand for 10 years but the quality fell off and I was desperately looking for something else. Glad I tried it, won't be trying anything else.

Did not get results
I have had many many years of Keratin treatments. I was anxious to try this one. I found for my hair which is not curly just wavy that it did not straighten it at all. Maybe it does fight the humidity and frizz a bit but I wanted that straight look. I am disappointed and I have tried 4 times using the entire bottle up over the past year. Gotta try something else, maybe go back to the Rejunvenol 4 day which worked better than this. Try try again! sorry

Wow this is it
After spending $400 for each keratin treatment, finding this was was a definite money saver. I bought one bottle in Aug of 2022 and now that I'm down to one treatment left I'm looking to buy again now in Oct of 2023. Just did my hair 2 days ago and I was worried that it might have expired but my hair turned out great. I can buy my favorite Babyliss pro flat iron and this every year for less than one treatment was costing me. It changes my hair game and tames the fly aways when I go for a curly look and cuts my flat iron time down from an hour + to a little over 20 min. I've ordered one other treatment off Amazon and thought I was going to die from the fumes and never tried to order keratin treatments again but then I stumbled across this a few years later. Don't try to save money with other products, this last longer than my salon treatments were lasting and as long as I use keratin friendly products it stays for more than 6 months, of course new hair growth has me re-treating more often than that. I did take a break for about 6 months this year after I accidentally stripped this from my hair trying a new hair product. This is a win. It is a little fumey so good ventilation is a must. Also I have tried letting the product air dry and blow drying, both work but blow drying gave me better results. I wash my hair with clarifying shampoo, let it dry and dye it the night before. Rinse the cream hair dye out and wash with clarifying shampoo again and let it air dry again. Then apply the treatment the next day brushing or combing through a section at a time to make sure I'm saturating each section. Blow dry then flat iron small (really small) sections at a time, going over each section 8 to 10 times. My hair is past my bra line and the application took about 3 hours from first spray to last section flat ironed. It's a project and I did think about paying someone to flat iron it but I guess I'm too cheap. Maybe next time. Smells good, my hair is usually kind of stiff when I flat iron it but this product gives me slinky flowy hair. Love that it comes direct from the company in a nicely sturdy shrink wrapped bottle. Quality and budget friendly compared to salon prices! I am bi-racial have 3b hair, I have seen this on 4b hair and it still has great results too.

Best on the market
I very much appreciate being able to buy Lasio from this seller. This product is 5 star. There is nothing else on the market to compare. I can’t even imagine my hair without having this Keratin. I’ve tried every keratin product on the market for decades and this is by far the best. It can only be bought through a licensed seller which is a travesty but anyway I give my heartfelt thank you for selling this to me allowing my horrible frizzy breakaway hair to look silky and healthy. Thank you. Again. On another review I mentioned I don’t follow the manufacturer directions. I use this every time I shampoo. Shampoo/condition as usual (twice/week) Towel dry, then apply a few tablespoons of Keratin. Put the towel back on and wait 15 min sometimes longer. Blow dry and hot iron as usual. Don’t make a big deal of this, anyone can do it there is no messing up this product. For those who wait 2 months, no need to.

The Best
First of all, this is a real review!! I am always concerned that raving reviews are fake - this one is not. I have wild hair that is part straight, part wavy, part very curly, and ALL frizzy. It builds on itself and turns into a fro even in little to no humidity. I have tried a few different keratin treatments from Amazon after getting tired of paying hundreds in salons and not getting results, and this is by far my favorite! A few key things to know about this treatment: - It is more expensive than some other treatments on Amazon, but this is because it comes with WAY more product! Other brands give me only 1-2 treatments max while this single bottle gave me 3 (my hair is halfway down my back) and probably could've been stretched to 4. WORTH THE EXTRA PRICE! - It does have pretty horrible fumes, so use it in a very well-ventilated area - Lasted for about 3 months. Other brands lasted me about 2 months, but by month 2 my hair was completely back to normal. With Lasio, my hair was still manageable at month 3, but I could see some frizz coming back through and decided to re-do the treatment. Additionally, I noticed that with other brands, my hair was very straight after the first wash, but 2-3 washes later it became wavier and slightly frizzier (although not even close to completely back to normal). With Lasio, my hair stayed much straighter and frizz-free after multiple washes. - My very favorite thing about Lasio is that you only have to wait 1 day before washing. My least favorite thing is that you have to avoid sulfates AND sodium chloride while some other brands of keratin treatments only require avoiding sulfates. That being said, it is still worth it to stick with the Lasio. After trying other brands, I will be purchasing the Lasio from now on!

EASY DIY, NO NEED TO GO TO THE SALON ANYMORE!
I was paying close to $200 for keratin treatments once or twice a year in the salon, so I finally decided to bite the bullet and try to do it myself to save money. It turned out to be a lot easier than I thought! I used maybe 1/5 of the bottle for my first treatment and I have thick, fairly long hair, so this 15.87 oz bottle will last me over a year, since I will only need to apply it maybe every 3 months or so. Therefore, it was absolutely worth the price. All you need to apply it is a spray bottle, some clips to clip your hair up so you can separate sections, a comb, a blow dryer, and a flat iron. You just spray it on each section and comb it in to saturate the hair, then blow dry and flat iron. There are also YouTube videos available that can help guide you. FYI it does not come with the pump as pictured, so you will just need to pour the contents into a spray bottle as needed.

Follow Directions
I previously had this same Lasio Keratain treatment applied in a salon to the tune of about $600. This is the exact same product and if you follow the directions you will get the same result at a small fraction of the cost. It is very important to watch the Lasio video on the application process and to begin with clarifying with the Lasio clarifying shampoo - at least 2 shampoos to open the cuticle to allow the product to penetrate. The blow dry and flat iron techniques are very specific (not standard), and if you don't follow their method, it won't work as it does in the salon. You do need to open a window and turn on the bathroom fan, if you have one, and be careful not to breath in the fumes during the heating process (where the chemicals are released) - mostly with the flat iron. I have found that it is a good idea to use the Lasio shampoo and conditioner afterwards because it is sodium free which is a killer to the Keratin - beware if you have water softener in your home because the salts strip the Keratin. Also if you have the patience and time you can wash this out the same day after you flat iron it in - which is great. Totally worth the money and a huge savings over the salon treatment - but you must take precautions and follow the Lasio instructions in order to get results.

GREAT alternative to the salon (exp. only)
I would first say that I would only suggest this for people who have gotten a keratin treatment done at a salon to have the right expectations about how best to use this safely and how long it takes. I've been getting keratin treatments for years and the price just keeps going up and up at the salon so I needed another option- well, I found it! So happy with the price and how many treatments I will get out of one bottle. Pictures: 1-After shampooing (didn't have a clarifying one, but used a rougher shampoo and washed twice), and blow drying as straight as I could get it, but it would normally be a huge wavy frizzy mess. 2-After blow drying after putting the treatment in. 3-After using the straightener. I was really happy with how it all went, but I may try more of a coloring brush to put it on next time rather than a spray bottle and comb. 4- This is 5 weeks later and only a blow dry done (no straightener yet) after a trip to Mexico and some salt water and chlorine pools. It would probably have lasted longer than it has for me, but I used a harsh purple shampoo which basically stripped it out so I know not to do that next time.

Make sure if you were doing this at home that you are in a well ventilated area and have some kind of door open because this stuff stings your eyes and nose!!! I did this myself and I’m pretty happy with the results! I did it not that long ago so I will update this when it’s been a month! I have 3B to 3C hair and I’ve never been able to blow dry it completely straight on my own but with this keratin treatment I can blow dry my hair straight! It’s awesome. And I love how loose my curls are! They’re almost wavy. It’s like having brand new set of hair 😂

I like it so far!
So far, I like this product. I had been a little worried about whether or not this product was legitimate Lasio and whether or not it was safe. Here I am to tell you that I survived! I did use safety glasses, gloves, and a mask. Honestly, the worst part for me was when I was applying the product. The fumes didn't seem to bother me except during that point in the process. I made sure to have the window open and my bathroom fan on. I used my spray bottle that I bought from Walmart. I would buy this product again, but I probably won't have to, as I barely used any product. This will last me a very long time, I'm sure! I attached a picture to show before and after. Ignore the cookie monster blue color on my face. That's what happens when you eat too many cookies. Anyway, I'm glad I bought this product. Let's see how long it holds up though!

Perfect like always
I have been using this product on and off for years. I stopped using it for about 3 years and let my hair grow out curly. Got tired of the “fro” look and decided to go back straight and non frizzy lol. I cut my hair before applying product so that’s why my hair is shorter in the second pic. 1st pic is after washing and blow drying it and the 2nd pick is after the product and about 3-4 washes (maybe 3 weeks after applying the product.)

Finally Salon Treatment at Home without Fume
I am super pleased with the product. I have tried doing Keritain at home but they made me cried so much. I gave up. I normally do this in a salon and I would be paying $150 to $200 for it. Nowadays I need to dye my hair so the silky smoothness is gone once I dyed my hair! This one is truly fume free as long as you wait until mostly dry before you iron. I first dyed my hair and directly applied on wet hair instead of during the hair first as another customer suggested. It was better because the dye made my hair quite coarse. If I dried it first I might lose a lot of hair in the process. I put the treatment in a spray bottle. I sprayed in the shower and made sure to avoid scalp. I did acidentally reach the scalp so I quickly rainse it off to avoid the tingling feeling. After I am done, I dried slightly with a towel and combed my hair to let it air dry. I waited an hour and half before I ironed the hair. While it was air drying I already felt the smoothness of my hair. I did iron a little wet and it had a bit fume but nothing compared to the old kind. Once I finished I was so happy with the results. It felt like I went to the salon. The bottle is a bit pricey but it Worth's every penny. I can use probably another 6 to 8 times in the future.

I have wavy/curly very frizzy hair. This product worked amazing on my hair. I went to Mexico after using this product and my hair was able to air dry just absolutely perfectly, I am obsessed! It is now 12 weeks later and it has lasted me this long, I still hairdry my hair with minimal heat but can tell it's starting to wear off so I will be doing it again! Love it, worth the $$.

I don't think I need to say which one is which :) I've done Keratin treatment many times at home; all I can say is that you shouldn't do it if you don't want to follow all of their instructions. They have a 20-ish-minute video on YouTube that you need to watch first.

This product is fantastic. I used it the other day and it was incredibly easy. All you need is a clarifying shampoo, a blow dryer, and a flat iron. I was amazed at how fast and easy this was and also how great my hair looks and feels. By the way, I have shoulder length, thick hair and only used a quarter of the bottle, so I know I can have at least 2 or 3 more treatments within this bottle. (I put it in a small spray bottle to put on my hair and it worked wonderfully) Great price for a great product.

This actually works!
This product really works and for the first six weeks results are comparable to salon keratin treatments - my salon treatments keep me silky smooth for about three months. As such, I use less for cost effectiveness and more for saving time.It is critical that you apply it according to the directions so you may want to have an assistant for your first few "trys". I have gotten adept at the application enough to be able to do it myself. Be aware there are indeed chemicals in this that may cause some irritation to your eyes and nose so applying in a well ventilated room is advisable.

Definitely a legitimate product as I have used it at high-end salons so I know what the product should look and smell like. Very easy to apply.

I will definitely keep ordering as I’m so done paying so much $$ at hair salons. I just washed it out today and my hair looks and feels amazing. Highly recommend this product for those who have frizzy, curly hair. However, I would get something stronger if your hair requires it as this product is not as strong as other products.

Meh…. I have mixed feelings…..
On one hand, it’s way better than paying hundreds of dollars at a salon. On the other hand….. it made my hair feel kind of gross and sticky and very weighed down. Shared some with a friend and she used it “off label” in a totally different way than the instructions say. She was fairly happy with her results. I’ve noticed on these reviews that several other people said they use it in a different way than instructed. One person even said she uses it every time she shampooed her hair and gets good results. Maybe that’s the key….. use in a different way than Lasio suggests?? (I used it according to instructions on the bottle and videos ~ and I wasn’t super happy with results).
