Resultaat na gebruik.

Geur

Prijs

Dit product maakt je haar zijdezacht.

Ik heb dit product leren kennen bij mijn kapper en meteen zelf aangekocht. Het maakt je haar heel zacht en de pluis verdwijnt. Het is een prijzig product maar zijn geld wel waard.

Easy to use

One product does it all

Fantastic!!

This product saves my hair. I dont need conditioner, and K18 just repairs split ends and leaves my hair even more conditioned for every time I use it.

Works well

(translated) Did what it said my hair was less dry and frizzy

Odor

Operation

Very pricey

Never without

(translated) K18 is a godsend. My hair has become so bad due to wrong blonding by the hairdresser. Without k18, my hair is a bunch of straw. Fortunately, with k18 I can still let my hair grow out instead of cutting everything short.

Economical consumption

A delicate fragrance

Instant absorption leaves no residue on hair

Hair rejuvenation

(translated) My hairdresser told me about this mask. This is a great remedy, after a week of constant use, my hair started shining and seemed more vibrant. The dryness that results from applying hair fixing products has disappeared and the hair looks healthy, shiny and full of energy.

09-02-2026 | monique bartniczok

So good for my hair

(translated) My hair is so revamped with the use of k18 and even cheaper too at Deloox

My experience with the K18 Leave-In Molecular Repair Hair Mask 150 ml

(translated) I am really impressed with the K18 mask. My hair felt so much softer and healthier after just the first use, like it was finally coming back to life. I didn't expect a product to make such a difference, but this has really become a permanent fixture for me.

21-01-2026 | Leonie Hoogenboom

Very soft

Easy to use

Results clearly visible

Duration

Fantastic

(translated) I had quite dehydrated hair and you can just see that this product makes my hair more alive again. I have a slight wave and it becomes a full wave after using this stuff. It is very easy to use. It makes my hair incredibly soft without weighing it down.

10-11-2025 | Elly Van den Heuvel

Lifesaver

Nourishing and restorative

Leave-in mask (saves time)

Pricey

Bought 2nd bottle - can't live without it

(translated) My hair gets drier with age, and I still dye my grays. So this product is a lifesaver. My hair feels softer, falls better, and looks healthy.

17-05-2025 | Sara

Disappointed

(translated) To be honest, I had high expectations for this product, but unfortunately, it didn't live up to them. I didn't notice any noticeable difference.

07-02-2025 | Sibel Yorulmaz

Super

(translated) It does exactly what it's supposed to. I notice more shine and a healthier appearance.

16-01-2025 | Stephanie Zwartjens

Better than all other repairers

really works

Best product ever

Pricey for the content

Best product ever!

(translated) My hair was broken and quite coarse. This product really helps a lot; it softens your hair and repairs the damage. I'll never use anything else but this. It's truly the best product I've ever used.

04-01-2025 | Mirian Renzema

Awesome

(translated) What you feel after treatment so soft the hairs are completely restored

Super!

(translated) Perfect in all areas. My hair is really healthy again after all the treatments in the salon. I have had highlights for years but with this treatment it is not visible.

Less time spent washing your hair

Hair has a beautiful shine

Hair doesn't feel so dry

Great!

(translated) I have naturally curly hair and have been using a flat iron for years, which has caused my hair to become very damaged. K18 has really helped my hair! My curls feel much healthier now and my curl pattern is finally coming back nicely. I like that you can just leave it in your hair—no hassle of rinsing it out. Hairwashday is much shorter with this product! My hair feels softer and stronger, and there is almost no breakage anymore. It is on the pricier side, but the results are worth it!

12-12-2024 | Cathy Van Lierde

nourishes the hair

Your hair recovers from heat and color damage

K18 a miracle for your hair!

(translated) My hair regularly gets damaged by coloring and styling with heat. And this product from K18 really works wonders for my hair. Just follow the instructions and your hair feels silky soft again and can go for a few more months. Absolute recommendation!

04-11-2024 | Tania

Does its job!

Makes your hair stronger!

I recommend it 100%!!!

(translated) So far very satisfied !!!!! I had never bought or used this product before... but had been looking for something to strengthen/improve my unruly, not so healthy hair... for a long time. I dared to buy it, and have now used it 2X. I REALLY notice, even after only those 2X, a difference, improvement, healthier hair !!!

16-10-2024 | Coby Vd linde

I haven't tried yours yet

(translated) I love it better than olaplex it is easy to use wash hair K18erop 4min and you're done

15-10-2024 | Anja

Does what it promises!

Fantastic leave-in hair mask

(translated) This is my favorite hair product! Use a small amount. I rub it in my hands first so I can see where I'm applying it. Leave it on for 4 minutes and you're done! My hair is shiny and healthy!

15-10-2024 | Lee

Very good

(translated) Hair becomes softer, dead ends are reduced.

07-10-2024 | Sibel

Works great!

(translated) Even without conditioner it makes your hair very soft. Hair feels a bit stronger

03-10-2024 | Nancy

The solution

(translated) For my hair (lightened) quickly dry and frizzy, the perfect solution. My hair looks shiny and healthy. And very little of the product needed per treatment.

30-09-2024 | Julia

The best product for damaged hair

(translated) It's an investment but it makes a huge difference! This leave in conditioner is the salvation if you have damaged hair. In the store you pay a lot more so I'm glad I found it for a good price via this website

24-09-2024 | Sonja Jansen

Makes hair baby soft

The price, of course

Does what it promises

(translated) Had my doubts because I already use Olaplex. For hair loss, brittle hair and thinning hair, I wanted to try this product. I can say that my hair becomes soft and manageable, you now have the feeling that your hair has become thicker (feeling, in fact that is not the case) and I feel much better. Costs a few cents but then you have something. I will also try the other products.

23-09-2024 | Anais Indeherberge

Fast result

soft hair

Much needed for thick hair

Great product

(translated) I saw this product on tiktok and I must say this was the best purchase. My hair is so soft and looks healthier after 3x use.

22-09-2024 | Nancy Wojciechowski

Inside in care

Texture of the product

Let your hair air dry, very soft

Expensive for quantity

Use multiple times

K18

(translated) Top product, very competitive price, noticeable results after 4 weeks, I thought there was more in the jar

17-09-2024 | Sandra Rooroh

The hair is really nourished

Very pricey

Nice mask

(translated) Very fine cream that makes the hair really soft. Very expensive but certainly happy with it.

16-09-2024 | Rita De Prins

Hair mask

(translated) Does what it promises. It makes your hair soft immediately without weighing it down.

12-09-2024 | Annemiek Schenkels

The result after just one use.

Great product!

(translated) Simply great for your hair! Looks and feels better, much less dry.

30-08-2024 | Sandra

Easy to use

See and feel results immediately

Most precious

Otherwise there really is no downside

Fantastic leave in repair mask

(translated) I have terribly dry, damaged and bleached hair, have tried so many products but nothing helped. K18 is really a miracle, wash hair, do not use conditioner. Distribute 4 pumps in hair, leave for 4 minutes and then comb through and style! Easy and it works!!

12-08-2024 | Eveline

Super!

(translated) Great product that really helps! I have long gray hair that is just stiff Tried a lot and this makes my hair shiny and it moves!

07-08-2024 | Sylvia Arts

Good price

Great working leave in mask

Your hair is really improving!

Great stuff

(translated) My hair was really dry after I had highlights put in. Unbearable, I jokingly called them haylights! After searching for a product for this, I ended up at K18 via many good reviews. Also skeptical because I now have a shelf full of all kinds of stuff that doesn't really work that well. But after 2x I already noticed a difference, wow!!! Ordered here at deloox because of the competitive price. Delivered within 2 days, TOP!
