Leave-In Molecular Hair Mask, Repairs Dry or Damaged Hair, Reverse Hair Damage from Bleach, Colour, Chemical Services & Heat

Very expensive product, but it has worked on my hair. I have tried so many other well known brands, not quite as expensive hair repairing treatments and my hair was still in terrible condition from bleaching, It improved while having it coloured at a hairdressers, but I was unable to afford regular visits and reverted back to colouring my self, unfortunately my hair is not great on the top from over bleaching catching other strands of hair while attempting to colour my roots only. K18 leave in treatment is really good and has helped my hair, I am telling myself it's worth it in the long run, if I add up what I have already wasted my money on so far trying products claiming to repair your hair. Very happy this product is actually helping my hair and improving the condition, it's a Shame it is so expensive though.

Although it is very expensive, it does leave my hair in a better condition than any other Keratin products I’ve tried so far and so I return to it….albeit reluctantly.

Wow. It does work even after second use there is a huge difference with the ends of my hair . It’s an absolute GAME CHANGER. A little goes a long way . I only bought the smallest size but I do feel that will last a while . I only use 2x a week . I definitely will not be going back now !! Worth the money if you want to restore your hair . It’s magic

Just used for the second time after my hairdressing recommending after lots of dying then bleaching 4 times including a full head then I went abroad my hair was fried and went like straw I have long thick hair so I used 2 pumps on top running through and 2 underneath my hair running all the way through it now feels amazing and soft honestly I am shocked how it feels now

Don't waste your money Have used 5 times now to give this product a chance and my hair feels like straw. It's noticeably frizzier and a lot of breakage has occured. It has done nothing it's advertised to do. Very chemical smell and you need to be in a well ventilated room due to the steam and smell that comes off your hair. The only thing that's changed is my bank balance.

Fantastic for improving her health and appearance. It has really reduced my split ends and made my hair feel soft and moisturised. It smells lovely. My only issue is that this does cost a lot for a small size product however you do only need 2 to 3 pumps each use and can use just once a week to get a good result.

Excellent product, definitely recommend it It has worked on my colour treated hair. My hair feels soft and bouncy and gives my fine hair volume.

Bloody heck!! This stuff is amazing, I fried half my hair off last year and had to have extensions, I wish I had just tried this stuff cos my hair feels brand new after just a couple of uses 💜it’s a game changer for sure. Just don’t put it directly on your scalp or it can burn a bit!!

Muy bien

The quantity you pay for at the salon is very economical; it's suitable for more than 5 hair washes and is safe.

Tenía dudas por algunos comentarios que había leído sobre que no era para tanto, pero realmente puedo decir que funciona desde el primer uso. Mi pelo está decolorado, además llevo peinado bob, por lo que suelo peinar con calor y está rompiéndose. Aposté por este producto por su fama y puedo decir que desde el primer lavado se siente el pelo con más peso y menos fragilidad. Evidentemente si buscáis que solucione la rotura, seamos realistas, ningún producto lo hará. Si quieres mejorar la calidad de tu pelo y recuperar parte del daño, pruébalo. Es caro sí, pero los buenos productos lo son. No se necesita aplicar demasiado producto como cualquier producto de calidad.

I didn't use it that much but my hair is good

fortalece bastante. com certeza vou comprar de novo.
