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!

This used to be a fantastic product. Unfortunately they seem to have changed the content and when i received it, it had a sticker on it saying dont use in the same way as before, it has changed, read the instructions. It was TERRIBLE and I actually thought my hair was going to be damaged. It was like straw! Once I had washed it out after the new 90minute wait (?!) it got better but it was as though I had never gone through the process. Really sad to say they have changed this to be less than useless - it was my go to product.

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 .

I tried this as they discontinued my usual brand. You have to leave in for 90 mins, the most difficult part was leaving product in while you blow dry as it is thick and oily. very strong smell when you use heat, my hair is white and it lightened to yellow but I washed with purple shampoo and returned to normal. It has straightened my hair but there are easier to use products.

Unbelievable! Absolutely amazing! Love the result.

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.

This product is by far a miracle treatment to get that perfectly formed straight hair. My hair has never been in such fabulous condition. And, it doesn't' fizz when I'm out in rain or damp conditions. It needs less attention too as it stays looking great all day without any fussing or correcting. When out in the wind, it just falls back into place when back in doors. Sheer Bliss. Beforehand, I watched plenty of YouTube videos to ensure I applied it the right way. The best advice was to stick to the instructions. Also, I only wish I'd coloured my hair the week or two before as it did lighten my hair to a silly colour, which I hated. I had to stick with this horrid colour for 2 weeks. Seek advice on this.In the UK it is FORMALDEHYDE FREE so no smells at all and, less chemicals applied. I LOVE IT. My hair is just below shoulder length, wavy and finer than most. It goes fizzy in the least damp conditions and, put simply, it's annoying. For the length of my hair this little bottle 4 oz was about right. In fact I did have some left over. I would guess for the thicker, long hairy you will need a bigger bottle. It's much cheaper for our friends in the USA and, you get a bigger bottle. Lucky you. It's a good reason to move though. Happy hair days.
