K18 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 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

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

Tiny tiny bottle so be aware of that! But you only need a few pumps when you use it. It’s a heavy investment but worked right away to recover my hair.

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.

This was recommended by my new hairdresser to help get my hair back into better conditioner. After the first use I was surprised how good my hair feels. A little definitely goes a long way. You use your normal shampoo, no conditioner, towel dry hair and then apply a few pumps of the k18. It's recommended to initially use this for 4-6 consecutive washes then every 2-4 weeks for maintenance. I'm hoping this will be one my holy grails on my hair care journey! Only four stars given as I haven't used it long enough to determine if it's going to help my hair get into better conditioner, bit after the first use it's definitely feeling better!

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

This has totally changed my life! Having had long, lanky and extra fine hair I decided to have blonde highlights to try and give it volume. I found an excellent colour technician who came highly recommended and she recommended I use K18 once a week. Well, this has been an absolute game changer! I even get compliments from family and friends which never happened before. My hair seems to have improved in strength, is glossy and very easy to manage. Every day looks like a fresh out of the salon day. Yes, it’s pricey but you only have to use a very small amount once a week. It should last for ages at this rate. Whatever magic ingredient is in this the inventor has to applauded. I will keep on recommending it as I’m so happy. Just buy it and see for yourself.

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.
