## Description

Product description

Review: 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 desertcart 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.
Review: 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.

## Questions & Answers

**Q: What is the full list of ingredients from the bottle? Thanks!**
A: Lasio 1 day treatment

**Q: Does this product cause brassiness in blonde/ highlighted hair? I've had two experiences with keratin treatments and both caused some degree of brass**
A: Most keratins will cause the hair color to fade or become brassy. Mostly reddish undertones. It will subside but you should do a toner 1-2 weeks later if it does not change. Blondes are okay if they are lifted past orange. Just color treated hair. More so brunettes/light brunettes. This product however is not real. The consistency and smell is different and it shows in the results. Fake. I contacted the provider expressing my issue and was not responded back to. Beware. P.s Licensed professional.

**Q: what is the shelf life of this keratin?**
A: 0 days. I would HIGHLY recommend not purchasing this product. Had it applied at a high end salon in NYC and it made my hair fall out. General thinning and then a large bald spot. Took months of steroid injections into my scalp and supplements for my hair to start growing back. After sharing my story online I learned that I am not the only one who has experienced this adverse reaction. Several salon owners contacted me to let me know that they are taking legal action for damage caused to their clients from using this product and the corresponding flat iron. Take caution.

**Q: is this formaldehyde-free?**
A: NOOOO!!!, DO NOT BUY THIS PRODUCT,,IT HAS DESTROYED MY HAIR.  Yes, I am that serious. Amazon shouldn't even support this supplier.

*by K***Y on May 11, 2020*

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.
