KERATIN RESEARCH Brazilian Keratin Hair Treatment Straightening Smoothing Damaged Hair Repair Complex Blowout Long Lasting Organic Natural Results, Argan Oil collagen Proteins Amino acids (120ml x2)

I don’t usually write reviews but felt this product needed it! I’ve had a few Brazilian blow drys at the hairdressers but needed to find a cheaper alternative. Didn’t have much hope for this to be honest but I can honestly say it works so well and it may of even been better than the salon. It’s easy to do though it takes some time. I have very thick and frizzy 2b hair which usually leaves me looking like hagrid when I leave it to dry. This stuff means I can leave it to dry naturally and it is so soft and smooth. Dries quicker and feels so healthy. I applied the treatment about 3 months ago and it is still noticeably smoother! The only small downside is that it does leave your hair smelling a bit funky but only really when it gets wet. Once dried it’s not noticeable! 10/10 recommend!

I have used this product previously and the results were fabulous. it left my hair soft and silky with a glass like shine. However... The most recent product came with new formula and usage instructions. After following the instructions to the letter it left my hair feeling like waxy straw and had lightened it a lot more than the previous formula. I have lost confidence in this product and will not be purchasing this again.

This product is truly amazing ,I’m in my 60’s and I have very fine blonde hair due to bleaching and colouring over several year’s ,also I have a under active thyroid problem too which doesn’t help. In lockdown I sorted out some old family videos and my hair looked so different from the hair I have today , I still have my same hair style a short Bob but my hair used to move as I turned my head and it didn’t anymore UNTIL I had keratin research treatment on my hair my hair feels amazing and swishes lol . I have also been in contact with keratin research in Florida they have been so helpful answering any questions I put to them within hours they have a website so I do recommend you contact them directly if you have any questions you need answered. Hope this may help too I have been using plantur 39 and I must say I found it to do what it says on the tin, my hair loss in my comb was next to nothing whilst using it however since I’ve treated my hair with keratin I’ve used a sulphate free shampoo and conditioner as it advices , however my comb has again lots of hair fall in it . Problem solved as I have found a sulphate free caffeine shampoo with great reviews, it’s called Grow me shampoo by Waterman’s . I used Keratin research express treatment which I purchased on Amazon Uk be very careful of eBay as this product is selling on eBay with unbelievable postage charges, so please be very careful. keratin research say it has a good shelf life of up to 2 years after opening if stored correctly , a 120ml bottle will do 3 treatments on my short hair .

If you’re in the U.K. - it has NO FORMALDEHYDE version. So no need to worry. You do get a strong smell when applying it to your hair though (open windows, maybe move around), but no scent or irritation when straightening your hair. It was a long process (expected) but considering I was technically saving £150 to do it myself, I cannot complain. The first affect was okay, it reduced my curl a little and made it shiny but not wavy or straight (which I didn’t want anyway), the back of my hair was very resistant. So I re-did the process but this time without using clarifying shampoo. This gave a better effect (from type 4 hair to now maybe 3b). So far (1 month), still good. I even swam every single day in the salty sea on holiday for a whole week and my hair remained as it was before, I did not need to straighten it or anything. With this your hair does feel drier if you’re not careful, but daily argan oil and castor oil (for VERY dry days) does the trick. I will use them again but I’ll use the treatment specifically for curlier hair.

This product made my hair smooth and vastly reduced frizz. If you follow the instructions it works... I am a 63 years old white female with greying hair that's grey and frizzy all over but particularly around the hair line. It doesn't hold a curl & becomes frizzy as soon as I step outside. It has a little natural wave . It is coloured red although frizzy it is soft . I followed the instructions to a T. The results were smooth hair that shone and dried much quicker than normally. But if like me you have naturally flat hair but like me you like fulness..then bare in mind this will make your hair lank.. it's for this reason I won't be using it again...I like big hair and this product did smooth the cuticle but made my hair too flat to my head..if you have thick bushy hair that you want less bushy I can imagine it would work

Ive used keratin treatment for many years now. My own fault but I expected the bottles to be bigger I didn't check this before I ordered. I usually use coco keratin treatment but thought i would give this brand a go. First the clarifying shampoo didnt seem to strip my hair as well as the others I've used in the past, not sure if this matters or not. This brand did leave a burning sensation on my scalp, more so than the coco brand. I followed the instructions, after straightening my hair felt like straw... I resisted the temptation to wash it out and waited overnight. Again if I was to compare with coco brand at this stage my hair felt better with that treatment. I washed and blow dried and straightened and yes I can tell its had keratin treatment, it feels softer and easier to manage but I can still feel the treatment in my hair, with coco at this point I can feel no dryness or left over treatment. It's only been a day so I'll report back on how it feels after a few more washes. I think next time I'll stick to what I know though 😏 *Update* Although it did the job, it didnt last as long as coco does, I'll be returning to using that as my go to.

Never but this product, it smells like hell, and certainly has strong chemical good enough to cause cancer or other issues. I couldn't keep this product on my scalp for more than 2 hours and its been 2 months now, that I have lost half of my hairs. I never had a hair loss problem, prior to using this product. Absolutely, bad choice and terrible product for hair.

Works well, Easy to use Saves money ( same procedure in salon will cost 5 times more)

Tratamiento muy recomendable te deja el pelo listín encrespamiento. Las instrucciones tan en inglés tuve k mirar tutoriales en YouTube.
