K18 Mini Leave-In Molecular Hair Mask, Repairs Dry or Damaged Hair, Reverse Hair Damage from Bleach, Colour, Chemical Services & Heat, 15ml

I feel upset that I’ve gone so long without knowing about or using this product. It’s been transformative for my straw-like, damaged, bleached hair.The first time I used it I was confused, because I had just rinsed the bleach off my roots and used a couple of pumps in my hair and, when it had dried, somehow my hair felt not just good, but the best it’s felt in years. I thought, surely it’s not that tiny amount of product that I used that’s made the difference??? But it was! Miracle stuff, just a shame about the price.

Life saviourThis is best one on marketHair thick & silky and shinyIt's very expensive but I am saving to buy bigger bottleThis is worth. Best mask I had recently

Changed my hair. Amazing product. The best I’ve used

I would give it none but cant so gave it one. Waste of money, hugely expensive and sold by the beauty journalists in weekly mags. Don't bother seriously.They get their kick backs to push it. I like a fool fell for it. Won't name the journos but caveat emptor

It's a nice product however when I saw the size of it I thought that it's definitely overpriced for the amount you get. It should be about half the price of this. On the flip side it does make a difference and isn't heavy or greasy. It smells lovely too.

I have so much to say but can't write all the good things about this one.In summary:1. makes your hair bonds stronger (Wont break from length)2. Makes your hair so silky and soft3. Lasts long (6 months) - I have mid length hair and little product goes a long way4. Instantly repairs damage - 3 uses.

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.

Fantastic product
