Works very well. I applied it onto my hair in the outdoors and had no trouble with the fumes, I kept it for a week on my hair. It’s been around five weeks after using it for the first time and it’s still looking fabulous. I totally recommend it and will keep buying it. I am not a fan of writing reviews but this one is a must. ### ⭐⭐⭐⭐⭐ Salon Results -- It Works, But Know What You're Doing *by on Reviewed in the United States October 17, 2022* This is an excellent keratin treatment, and I plan to continue buying it -- but it's not for the faint of heart. I do EVERYTHING to my hair at home, and have had a handful of keratin salon treatments, and this is a case where experience helps. If you're a newbie to home treatments or to keratin treatments, here's what you need to know.* Fumes. You will have them, and on this one, they are BAD. They start the minute you open the little bottle, so be prepared. The fumes are what make it work, but make sure you're in a well-ventilated place, and proceed carefully.*No, you don't have to use sulfate-free shampoos to keep keratin in your hair. (Great news for me as my hair hates that stuff.) You do need a clarifying shampoo before you treat. After the treatment, any mild, moisturizing shampoo will work fine.* The longer you leave it in before shampooing, the better your results. Which leads us to...* DO NOT saturate your hair with the treatment. I have below shoulder length, thick hair, and only needed half a bottle.--and this is a small bottle. When people complain about a "sticky" feeling from keratin, it's because they used too much.Here is the process I followed to achieve utterly amazing, smooth, no-frizz results on my thick, ridiculously coarse, unmanageable hair:1. Shampoo'd with a cheap clarifying shampoo and let my hair air dry.2. Put on gloves, opened the bottle, got KNOCKED OUT by the fumes, and applied the product to my air-dried hair with my fingers.3. Used a thick-toothed comb to distribute it evenly.3. Waited one hour.4. Used my hair dryer and a brush to blow my hair straight with the treatment still in it.5. Used a flat iron at 450 degrees to iron my hair, tiny section by tiny section. I watched a movie while doing this, it took a long time. FUMES, FUMES, and more fumes.6. Admired my beautifully straight, shiny, hair.7. Left it in for five days before shampooing. I was going to leave it in for just 3, but it never looked greasy or dirty.Results: It used to take me two hours to go from wet to straight hair. Now, I can blow it dry in about 10 minutes and flat iron it in another 10 for far, far better results. I have no frizz and tons of shine. Best of all, if I let it air dry, I get smooth, soft waves that also look great. I could NEVER just wash and go before.I plan to continue using this treatment every few months. The others on Amazon are all in the $50 to $60 range, which is cheaper than going to the salon, but still a little pricey. This $12.99 treatment works as well as the ones I paid hundred of dollars for in the salon. ### ⭐⭐⭐⭐⭐ BAD FUMES *by on Reviewed in the United States November 18, 2018* FIRST OFF ALL I AM LAZY TO REVIEW PRODUCTS, IVE BEEN USING KERATIN FOR QUITE A WHILE FROM REJUVENOL COPOLA ( WHICH WAS THE BEST ) BUT SINCE I STARTED TO DO IT AT HOME BECAUSE ITS TOO MUCH MONEY AT SALON I HAVE NOT FELT MY HAIR SO SOFT AND STRAIGHT. YES THE FUMES ARE STRING I HAVE ASTMA BD PRACTICALLY BLOWED IT OUT ON BALCONY WITH 30 WEATHER BUT I GOT IT DONE AND USUALLY MY HAIR DRIES KINDA DRY LOOKING AND WHEN ITS IRONED YOU CAN SEE THE ROUGH BURNED ENDS BUT WITH THIS ONE ITS SMOOTH SOFT STRAIGTH AND MY ENDS DONT LOOK DRY LIKE WITH THE OTHERS. I HAVE OVER PROCESS HAIR WITH BLEACH THAT I DO CONSTANTLY HIGHLIGHTS AND I HAD JUST GOTTEN DONE THREE WEEKS AGO. IT HAS A CHOCOLATELY SMELL AND IF I WOULDNT HAD CUT MY HAIR THE 2 ONCE BOTTLE WOULDNT HAD BEEN ENOUGH I BARELY MADE IT BUT I WANTED TO TRY IT BEFORE GETTING A BIG BOTTLE. NOW I HAVE TO SEE HOW UT COMES OUT WHEN WASHED OFF HOPEFULLY MY HAIR WONT FALL OUT. MY ENDS LOOK A LITTLE DRY ON BACK BUT ACTUALLY THEY ARE NOT THEY ARE VERY SOFT ITS NOT I HAVE SHOULDER SURGERYY IT ITS KINDA HARD TO BLOW OUT THE BACK AND IRON. ## Frequently Bought Together - Keragen - Brazilian Keratin Smoothing Treatment, Blowout Straightening System for Dry and Damaged Hair - Forte, Sulfate Free - Eliminates Curls and Frizz, Medium to Coarse Hair (2 Oz) - KERAGEN - Clarifying Shampoo with Keratin and Collagen, All Hair Types, Sulfate Free, 2 Oz - Deep Cleansing, Purifying, Refresh and Reset Damaged, Color Treated Hair - KERAGEN - Nourishing Hair Serum for Dry Damaged Hair - Argan Oil for Hair Treatment - Brilliant Shine, Heat Protection with Paraben, Phthalate and Sulfate Free Formula (1.7 Oz) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/57804318-brazilian-smoothing-keratin-hair-treatment-frizz-control-2-oz-formaldehyde](https://www.desertcart.jp/products/57804318-brazilian-smoothing-keratin-hair-treatment-frizz-control-2-oz-formaldehyde) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-26*
