Fantastic product
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

100% excellent results
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.

Works well for me
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

Game Changer!
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.

Not buying again
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.

I was hesitant to buy this at first. But, I did it anyways, thanks to all who gave reviews. My hair looks amazingly beautiful, shiny, healthy, soft. For sure it’s the best investment ever for my hair. I have done treatment for more than $500/ treatment. This is the most economical way to do it. Just follow exactly the directions like I did. Now I’m enjoying my hair everyday, can even skip to bathe my hair, and still looks great. I am giving this a review, for saying thank you for your product and the other people out there who are hesitant to try.

Producto muy eficaz para las que queremos lucir una melena lacia. Cuida el pelo, y desde luego lo alisa. Dejadlo siempre actuar 3 días antes de lavar el cabello. Antes me realizaba un tratamiento similar en la peluquería, pero el precio es tan elevado que no siempre puedes permitírtelo pagar. Lo recomiendo 100%. Si el cabello lo tenéis muy estropeado, no paséis tantas veces la plancha.

Amazing product. Smell wasn’t horrible. Open all windows and use a fan to blow the product steam away from your face. Take your time, I spent a couple hours on this. But it’s worth the time taken, don’t rush. I sectioned each piece and did tiny sections. Fully saturate hair, comb a lot. Then at the end sort of squeeze the hair towards the ends to remove excess product. When you blow dry your hair originally make sure it’s as straight as you can do with a round brush. I personally straightened my hair like 10+ times each strand. Until it was stick straight. Don’t wash your hair for as long as possible, I used dry shampoo to maintain the style for as long as possible. This stuff really really worked. I will say, Lost a lot of my curl… which is personally what I wanted to do without using a relaxer. If you are afraid of posing your curl use the other version of keratin from this brand, it’s apparently less strong but still effective. I will continue to buy this product!! So damn happy with my hair. I live in San Francisco where it is extremely foggy at all times. My hair frizzes up so much, but now it’s smooth and super soft. I feel like I lost most of my split ends using this. My review pictures included 1) my hair air dried with some “de-frizz” products 2) hair straightened after applying the keratin treatment 3) a week after applying the treatment, this is my hair air dried and applying no heat just olaplex oil. My suggestions for products to use for after care… Amika the Kure hair treatment (bond maintenance), sulfate free shampoo…sulfates makes keratin seep from the hair, hair oil on your ends, a super moisturizing hair mask/conditioner. I use Davines hair care and it’s amazing but expensive. Amika has cheaper options. Don’t crease yourself hair for as many days as possible and brush your hair everyday and keep it dry for as long as possible.
