KERATIN RESEARCH Most Effective Brazilian Keratin Hair Blowout Straightening Smoothing Hair Treatment Instant Professional Results Salon Formula With Clarifying Shampoo (120ml+120ml)

Firstly, this product works on my hair. I have wavy hair with strong waves in places and the formula has completely flattened them. It is worth noting...as many seem to be complaining about the fumes... that during the process, you will blow dry and straighten your hair without rinsing out the product so, yes, it creates a lot of fumes, it contains formaldehyde and you need ventilation...ie a door open to outside in the same room. Not just a little window. My hair is just past my shoulders and there was plenty of formula, had a bit left over. The shampoo has lasted 6/7 washes. I have not used conditioner since as haven’t needed to. It is extremely important that you do NOT wash the treatment out for three days. Your hair will be better for leaving it.. if you do then your results will not be as hoped. I Did this at home and it’s money well spent, in the past it has cost over £100 at the salon and genuinely, the results, for me, are the same. Just follow instructions properly.

I followed the process step by step and the results are amazing! I've had Keratin treatment in hairdresser's before and I must say the results are similar, even better! The photo is immediately after the treatment. I'll upload one more after I wash it.

It is great. I have very thick frizzy hair especially when blow dried but after doing this my hair was soft and shiny with hardly any frizz. It was easy to apply but would recommend having someone help and had a very strong smell when drying and straightening but definitely worth it seeing the results

it did not work, it is too strong and caused me dry scalp with heavy dandruff which I never had, itchy and sensitive scalp. would not recommend it for any one.

I have been using this product since Covid and I find it really effective - my hair dresser applies it for me and does the straightening with the straighteners. I have the process done 3 times per year and it lasts well

This really is the best product to use at home for professional hair straightening Has taken all my frizz away and best thing I’ve done for my hair - just make sure your prepared with using the right hair products - you’ll need paraben and sulphate free of everything you use ie hair serum, hair straightener , I did so much research on this and so happy I did now as it’s just an amazing product

Absolute miracle stuff this is the ultimate game changer, my hairdresser recommended a keratin treatment at the salon. It would cost £150. I had never heard of this before so obviously went home and googled it and found this product was not one single bad review and I can tell you, it’s worth every penny. I have washed my hair a few times since doing it and it’s still luscious and silky and I would only advise to follow the instructions down to the T! No matter how strange it might sound it works perfectly. This product have saved me so much time and less use of straighteners and curling tongs. I wish I had discovered it years ago.

As with many things, this product may not be suitable for everyone, despite following the instructions carefully. It requires patience. I very much strongly recommend wearing a mask and eye protection while using this product if you can. Even with a double mask, I experienced irritation to my eyes, nose, and throat. The formula has a strong odor. It's best to use it in a well-ventilated area, particularly when blow-drying your hair.
