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.

I was very curious to try the K18 Leave-In Molecular Hair Mask because my hair has been through a lot: bleach, colour, and heat styling. After a few uses, I can honestly say it does make a difference, but it’s not exactly a miracle in one wash. First, it’s important to follow the instructions: shampoo, skip conditioner, towel-dry your hair, and apply a small amount. You really only need a tiny pump. The product feels light and not greasy, which I like, and it doesn’t weigh my hair down. After about 3–4 uses, my hair started to feel stronger and less brittle, especially on the ends where bleach damage is the worst. It doesn’t make the hair super silky like a traditional mask, but it improves the structure of the hair over time. My hair feels healthier and looks a bit smoother. The downside is the price for such a small bottle. Also, if you’re expecting instant softness like a regular deep conditioner, you might be disappointed because that’s not really what this product is designed to do. Overall, it’s a very interesting treatment for damaged hair and I can see why it’s popular. It takes consistency, but it does help improve the strength of over-processed hair

I don't normally leave reviews and I would also never normally spend this much on such a small amount of product, but my hair is extremely damaged from lightening / dyes and straighteners. After one use, my hair is visibly improved and feels so much better. Highly recommend

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.

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.

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

I have used this product after 4 washes so far and even after the first use my hair looked and felt in much better condition. It now feels smoother and looks so much better. I have tried so many products to help my thinning, fine, frizz prone hair but most just add oil and make my already oily scalp more oily and my hair would look greasy even though just washed. It is expensive but, I have wasted so much money in the past on other recommended products. If this keeps giving these super results I will definitely order again.

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.
