Moroccan Keratin Brazilian Keratin Hair Treatment blowout Straightening Product Professional Grade Natural Organic Looking Results at Home or Salon (4oz Keratin)

Wow, this stuff really, really works, BUT - as other users warned - the fumes are truly AWFUL during the process (this review will be very long and thorough do skip to the end if that’s all you’re interested in). I included pictures for reference: the first is my hair styled pre-treatment (even flat ironed it still felt slightly “crunchy” after the first day), second is blow dried before doing this treatment, and the last two are after I washed and lightly styled my hair after day three. You can really see the difference! First, the good: For background, my hair is 2b/c, medium thickness with waves and some curl, naturally red but I dye it soft black. I wash my hair about once a week, dry it with a quality blow drier, and use hot tools every day with good heat protectants. I’ve bleached and dyed my hair with both semi-permanent and permanent dyes twice over the past six months, but I’ve been doing my own hair for 15+ years and know how to do it safely and with minimal damage. I had also trimmed my hair about a month before doing this keratin treatment so I’d gotten rid of most of my split ends. It’s been about three weeks post-treatment, and WOW. The results did not disappoint! I used a different highly-rated keratin treatment last year that I also purchased from Amazon, and while it was good, this blows it out of the water. My hair is smooth, silky and my blow drying is cut in half! It takes about 5 minutes with a flat iron on 360 to smooth out any areas that I want really straight or smooth, and my hair still holds a wave or curl that I put in it. I have no flyaways, no frizz, and my hair still has enough body that it doesn’t just hang there like after the last treatment. I took an extra step during the application/flat ironing portion to keep body and volume in my hair, and I’ll detail in a minute. The process: The kit comes with clear instructions - first you wash your hair twice with clarifying shampoo (I use the clear Neutrogena anti-residue shampoo because it’s cheap and it works), then blow dry it straight; section your hair and apply the lotion liberally, combing through with a fine comb to saturate and remove the excess; blow dry your hair straight in sections (a good round brush really helps); finally, flat iron small sections at a time at 400-450 degrees (make sure you’re using a REALLY GOOD flat iron with temp control), going over each section 7-12 times until you no longer see fumes, getting each piece REALLY straight. Then wait overnight or for three days before washing, running your flat iron lightly over your hair once or twice each day to keep it smooth. What I did to keep some body and volume in my hair was to apply the lotion at least an inch from my scalp, and over direct the flat iron during the straightening stage by holding the section up and away from my head and slightly rotating the flat iron like I was going to curl it under, but only at the roots. I did this several times a day during the three day waiting period, and it made a huge difference! If your hair is naturally very curly or kinky it’s recommended to still apply the lotion near the scalp but to over direct the flat iron as I described. Now, ON TO THE BAD: This stuff is TOXIC. When people mentioned “fumes” and needing fans/applying outside, I honestly just figured they were exaggerating because most people aren’t used to doing their own hair. NOPE. Please, please believe me that this stuff is incredibly irritating to your eyes, nose and throat, and you MUST have proper ventilation AND at least one fan blowing away from you when applying and blow drying. I was also dumb and assumed the worst time for the fumes would be during the flat ironing stage, but it’s noxious as soon as you open the bottle. I tried to use swimming goggles without the strap because my eyes burned immediately, but that didn’t work out well; I also wore two disposable masks and still had to tie a kitchen towel over my mouth because my throat was burning like I was breathing acid. I moved out into my living room, opened the patio doors, turned on the ceiling fan and set up two additional standing fans, and I still felt it. All that being said, it’s not any more noxious than you would find in a salon; by doing it at home, you’re still getting the same results through the same process, but saving at least $200. Would I do it again? Absolutely! I’m going to do it again once these results wear off. Just be careful, and it’s worth it.

I don’t write reviews for every product, but I couldn’t NOT, after using this treatment on my hair. After taking my time to read reviews and add multiple keratin/brazilian blowout treatments to my cart, I decided to give this one a try, the reviews tipped the scale - and I am not disappointed. I decided to try the treatment on a Friday morning, a day off from work, with plenty of time over the weekend for my hair to ‘process’ ahead of returning to work on Monday. I started by using the Olaplex clarifying shampoo, and blowed my hair 85% dry with my hairdryer. I used a bowl and a color applicator and began with the bottom/under hair and worked in sections until everything had a coat of this treatment on it. For reference, my hair is a smidge longer than shoulder length and I used about 30% of the bottle for this application. I combed the treatment alllll the way through, covered with a shower cap and waited 30 minutes. Surprisingly, even with the cap on, the treatment had dried in many places. I began again with the bottom/under part of my hair, with my blow dryer and a round brush, and although some parts were a little tangled, it was a quick brush out with a flat brush and back to the round and blow dryer. Like some reviewers, I did notice fumes that bothered my eyes while drying, so I opened a window and turned the bathroom fan on. After it was all dried, I began again with my flat iron, giving each section multiple passes. The whole process, from shower to flat ironed took about 2 hours. My hair looked good - but lemme tell ya, I was not prepared for the final transformation. Saturday I woke up and noticed some pieces that got a little kinked from sleeping (I did pivot to a satin pillowcase too) so I brushed them out gently and re-ironed them with my flat iron. I did not wash my hair this day. Same thing on Sunday - and no washing. Honestly, this was the hardest part, not washing for those couple days. But man, I am so glad I let this treatment work for 2 days. Monday morning, I washed my hair, using Lanza’s smooth shampoo and conditioner. My hair felt AMAZING wet, it was smooth and soft, which was a brand new experience for me. I dried my hair a bit with my towel and could not wait to get it dried with my dryer. My hair is a BRAND NEW girl. I dunno how else to say this. My hair is shiny and soft and all the flyaways and wavy sections have relaxed - it looks and feels amazing, and I’ve had a TON of comments/compliments about how great my hair looks and how shiny it is - and I’ve shared where to buy this magic in a bottle with everyone who’s asked. But most importantly, I have hair confidence that has been a complete game changer. I love touching my tendrils now - I just can’t believe my hair could look and feel this fantastic. I will never NOT use this. I understand it’s relatively normal to have these treatments every 4-8 weeks, as needed - and, oh yes, yes I will. Buy this, you will not regret your purchase!

I do it once every 3 months, keeps your hair smother and easy to brush

Excelent !!!! I used this product several times and it really works!!!!

The fumes are expected but they will ABSOLUTELY leave you gasping for air and your sinuses truly burning. Please use care, ventilate the room well and have lots of air circulating. Keep children and pets away during those hours. I am glad it is quicker than I’ve used before and washing sooner helps but the smell of sulphur is really very heavy and wears into your hair leaving an odor for about a week. Stains clothes. Had to throw away two hair brushes. Wasn’t able to remove the smell after weeks of soaking and scrubbing the bristles. Some mild skin irritation. These things are all expected and I have done this type of treatment many times with good results. It does what it says it will do. Always makes my hair significantly more manageable and seems to improve the quality of each strand no matter how harsh it seems. I might try a different brand to see if results last a bit longer considering how tedious this processing is to perform on yourself. No issues with shipping or handling. Product came as described and delivered results it supported. You just can’t imagine the smell.

I followed the directions to a tee and my hair feels like straw. First, the smell was unbearable. My eyes were watering, I felt dizzy after a while, and it left substantial amounts of product on my flat iron, and brushes. I immediately placed all but the flat iron in a basin and filled it with hot water and clarifying shampoo to sit overnight. I slept with a hair bonnet because the smell was awful. It says to leave on up to three days, but after I write this, I am going to shampoo and deep condition my hair with the hopes that some damage can be repaired.

The product is ok. It helps minimize the effect of humidity but it only lasts until you wash your hair again. Not permanent at all.

Great product and excellent price!
