INVERTO 60 Multi-Functional Keratin Hair Treatment Formaldehyde-Free Starter Keratin Hair Treatment Straightening kit 120ml

This is amazing product. It is easy to use, results are 100 straight silky, shine and soft hair. I have afro hair, and worked perfect. The best thing! It is Formaldehyde free, it does not smell awful like usual keratin treatment I have had in salon.

Came on time, and is easy to use.A bit of an odd smell, but worth it (would recommend as many windows open as possible!) but doesn’t have that overwhelming irritating stink of formaldehyde.I’ve 3a hair type and whilst it did have a positive effect I think 3 months would be more than long enough interval - not like what was in the description which I think said 3 months was minimum - but it does depend on hair type/washing frequency I guess!The main appeal for me was the low price compared to the salon cost, the volume is definitely generous and takes a couple of hours max (I used the shorter curl keeping method) and the savings when you’re on a budget makes it worth a try for sure!The instructions included were well written as well.

Very good product. I have extremely long hair (easily cover my breasts) and the whole bottle was barely enough to cover my hair, I had to brush it a lot to cover the tips and it was very painful! I washed the hair the next day cause I was afraid it didn't work ahahhaNext time I will buy 2 and use 1 and a half each time. It works perfectly if your hair is not very curly but frizzy, as mine is. The discoloration is real though, but I don't mind as the color it gave me is quite nice anyway!In the photos you can see the before, after and after the iron. Very shiny and soft, it closed all my split ends( my hair was very damaged, I had to keep it tied up all the time to avoid crying while brushing the day after :()Smells a bit funny and it smokes quite a bit when you are straightening the hair, but nothing too crazy.Will buy again for sure!

I have used it three times now, it's easy to use need an extremely well ventilated room. I did flat iron this time as I wanted to elongate my curls. I would suggest 2-3 passes with flat iron or u could end up losing curl pattern

Really impressed with this product. My hair is amazing smooth frizz free and looks great with little effort.Need a couple of hours spare to complete the treatment.

I had Keratin treatment done before which was formaldehyde-free and organic, I wanted to replicate the same result with this treatment but I must say that the formula is awful in comparison. It smells terrible and every time I wash my hair it still releases the same bad scent, as for the result itself it is not great either, I followed the steps meticulously doing the professional option given and yes the hair seems a bit more shiny and easier to manage but not really what I was hoping for.

Its really bad will make your hair more dry and doesn’t do any difference!! Really will never buy jt again!

Works great. Easy to use and so far lasted 2 months. No fumes and far from agressive. Not giving 5 stars due to the price as only serves only application on long hair. But I recommend.
