K18Leave-In Hair Repair Mask, 15ml

I really did notice the effect on my hair, it’s not making hair heavy and does not prevent it to have volume. I makes hair look and feel more healthy and thick.I asked my hairstylist at Vidal Sassoon salon (as I saw they were using k18 treatments there) if this mask is really a treatment that improves health of the hair, or if it just affects the look. And she said that it really works from inside of the hair.I always had lots of hair but they were quite thin. Now I use this mask 2-3 times a week for maybe 3 weeks, and I see a noticeable result, it feels like my hair is 1,5 times thicker and more healthy and silky

This is a big game changer it’s expensive but worth it my hair was very damaged dry but after just one use I noticed it was smooth and soft

My hair was damaged after a salon disaster with bleaching they actually burned my hair and patches snapped off went to a lovely lady who recommend this and it's been 3 weeks and the different in my hair is incredible it's looks so healthy

This has transformed my hair. I have very fine and fragile hair that breaks easily. I have never been able to grow it long because it gets so broken and shaggy. With this I have been able to grow my hair longer than usual and it gives an amazing shine. I will still never be able to have very long hair but I have actually never used a product that works as well as this. You don't use conditioner with this, and a small amount goes a long way. It is VERY expensive but when you have hair like mine it is worth it. I just put it on the ends and use a tangle teaser to comb through and let it air dry. Once it dries my hair feels a little crunchy at first but once I brush it through again it feel silky soft and shiny. It's definitely a five star product in terms of quality and ingredients but I've knocked a star off because of the high price, which also recently went up.

I bought the 5ml sample size which was perfect - though it looks tiny it has lasted six applications for my shoulder-blade length, medium thickness, bleach damaged, heat-treated, perimenopausal hair. I had noticed a lot of breakage, especially near my crown. My hair always felt frazzled at the ends and just didn't look shiny or healthy. I used Head and Shoulders clarifying shampoo then K18 for six consecutive washes, followed by Redken Extreme Length leave in conditioner. You have to wait four minutes once you've applied the K18 then style as usual (no need to wash out). It's simple to use in the shower routine and adds no extra time - in fact it saves time as you don't need to use conditioner afterwards.My hair felt softer and healthier after each use and others have complimented my hair. It's not got any particular wow factor after one wash but my hair is now 100% in better condition. Broken ends are smoother and less noticeable, my hair looks so much shinier, fuller and healthier. I'll have a rest from this now but probably do another six washes after my next lightening session to maintain strength and health.

I'm really not sure about this product. I do, however, have opinions. Ultimately the jury's out about the benefits and healing treatment on the hair long term, I have a few more uses left. I think my thoughts (which are complicated) could best be summed up as pros and cons for brevity's sake.Pros:- I fried my hair trying to add an auburn sheen - I used to dye my hair a lot and should have known better than to try again, but I was not prepared for the frizz I unleashed! Since the 2nd-or-so K18 application, my frizz is a lot less (but NOT gone!)- My hair does feel very soft- Frying my hair drastically reduced my natural curls, K18 may have helped start to bring these back - however changing my conditioner may have changed that too.Cons:- Price. Much like Olaplex, I feel this is very, very overpriced for what you get. The changes are not THAT amazing, and the amount of product is criminal.- Packaging. £30 for a 15ml, which is in an air-tight plastic pump that you cannot open to get any product left in the tube. I'm fully willing to bet there's a lot of product wastage there!- Hype. Hype never does anything any favours long term... yes, I think it helped with my damage from dying, but nothing's a miracle product and YMMV as to how much this helps you or not, how much a difference it makes or not. Personally it did make a difference for me, but I still expected more from the hype.- Long term benefit. I'm not sure about the long term pros of this product.- Method. How you're meant to use this product is very strict and I don't think it will work that well if you don't follow the instructions. Personally, my hair NEEDS a good conditioner, so having to omit conditioner... not so great. Also they recommend using it for multiple washes in a row - my hair cannot go multiple washes with shampoo each time and no conditioner each time, no way. And then there's the cost of using it for each wash, multiple washes in a row!- Amount. Goes back to price. I don't have masses of hair but I do have thick, longish hair and I could not make the amount they suggest stretch through all that. I had to use more, and that gets £££ as you burn through product.Ultimately, it's not a miracle product. It's a fairly decent product IF you have hair damage from chemical/heat, but if you're battling with just frizzy/thirsty/etc. hair I don't think it will do much. I do think the amount it will help you varies from person to person by a lot. And I really do think rave reviews, hype and marketing oversell how beneficial this product is.It is very expensive for what it is, and I think if you know your hair type and needs and have time to research or money to try new things, you can get better products which, if not cheaper, are at least more targeted for what you specifically need. It is marketed as a long term use product which is just not accessible price-wise for many people, myself included, and I don't know if the benefits will get any better than what it has already done for my hair.But it did help with damage in my specific circumstances - not to a miracle level but to a noticeable level.If you have the disposable income AND have chemical/heat damaged hair, give it a go. I would not splurge on a big size to begin with though, and I would be very, very realistic about the results and cost-to-impact you are going to see.

Love this mask. It makes hair look healthy and silky
