Keragen Brazilian Keratin Hair Smoothing Treatment - Blowout Straightening System - Forte 16oz

I have incredibly thick and curly hair prone to frizz, I have tried a few products and this has been by far the most effective. My tips are to ensure the space is extremely well ventilated, because the fumes from this are really strong and the chemicals in the fumes are not good for you. I wore gloves, ear covers, a face mask, a towel covering the back of my neck, and if you have sensitive eyes wear goggles as it does make your eyes run when blow drying/ straightening. You need a clarifying shampoo to use first (skip conditioner), and then work the product through your damp hair in sections, I left it on for an hour for full effect (put hair in a shower cap and chill for an hour, there weren’t any fumes until I had to brow dry so it was okay) and then blow dried on a cool setting (less fumes on a cool setting) before straightening with my GHDs (you need very hot straighteners for this to work). I straightened each section of hair 5 times. The thing I like about this product is that you can wash it straight away after (normally you have to leave it on your hair for 3 days!) so it’s nice to know that you wash all the chemicals out after the treatment is done (use sulfate free shampoo). You can feel the change of the texture of your hair even when wet, and it’s so much quicker and smoother to blow dry. Also the bottle is huge and you only need a small amount per treatment so it’s going to last me ages… This product is the best I have used, however note that it’s not formeldyhyde free (which is probably why it works so well!) so use precautions to be safe with it (use in well ventilated area and avoid contact with your skin.). You do get amazing results with this.

A great product. It actually works and now I don't have to chemically treat my hair anymore as this Brazilian Blowdry does a similar job without it snapping off. So pleased and will buy again. Just a tip, open your windows as you should do when applying any Brazilian Blowdry as this is a salon product. Ignore any negative feedback. Just follow the instructions and it will work. My hair is so much better and smoother.

Beat product for keratin treatment i have ever used!!! Will be buying more

It’s very good, works as expected but the smell is so strong - not that it smells bad, but very toxic and the fumes when inhaled it’s so difficult to breathe. i recommend in a well ventilated area and perhaps try one without the toxic smell. works well though.

This product doesn’t work. We followed the instructions my daughter even kept the product in her hair for 2 days still came out as curly as it was for the beginning

I used the product and do not get me wrong: I did not read the ingredients list on the bottle before using it however this was not specified in the product listing and formaldehyde has been banned from most countries as an extremely harmful ingredient and I am sure that it was banned from the UK for cosmetic products. This product contains it and I started getting suspicious when it started bothering my eyes in an unusual way: I normally get keratin treatments in the salon every 3 months but this one bothered me particularly. Upon checking ingredients I then realized why the incredible discomfort. Despite me opening the windows and ventilating the room for 3 hours the fumes still got to me and today I woke up as if I had drank alcohol or been in contact with something harmful as I have a headache, itchy eyes and a sense of nausea. I will contact Amazon customer service and make sure that this product can actually be sold in the UK. Update: one week after using the product my scalp started flaking in an extremely visible and unappealing way. I contacted customer support but no update on whether this product should be sellable or not in the UK. The product description does not specify any heavy chemicals used and even the Amazon robo advisor suggests that the product doesn’t contain any harmful chemicals, which is obviously not the case. To the seller: please specify the ingredient list in your listing.

Does not work at all!
