Tell me about K18 Leave-In Molecular Repair Hair Mask

[Sea_Otter spins]

I've been hearing about this lately and I was wondering if anyone here has used it. I never know if reviews are real and unbiased. How do you use it? How did it work for you? Is it better than a deep conditioner? And is it worth the price?

Thank you! I did a search earlier and that thread didn't come up.

I've used it. I use it about once a month now, because it's so expensive. When I use a deep conditioner, I literally use a big handfull, but with this, 2 ml is enough, and so, a bottle will last a long time. (it's still expensive though....). To be able to use this little on my BCL Lenght hair I have to detangle wet, and it has to be completely detangled, so that when I put product in my hands slip right though. Using this product before detangling or as a detangler is a big mistake that would mean wasting a ton of product and not getting many uses out of the bottle.

This can't really be compared to a deep conditioner, as it's not that at all. It actually repairs the hair (apparently...), a deep conditioner doesn't permanently repair hair.

I found that the K18 delivered what it promised. I was quite amazed at the results. My hair went from dull (pre LHC neglect, including a lot of swimming in chlorine without even rinsing afterwards...) to shiny, soft and more bouncy. I used it for 4 washes in a row, and now every month to maintain, as there is always new damage happening. This keeps my ends soft too, I apply more there. I am now over four months post last trim, and my ends are still soft and nice, but that comes down to other factors too, of course.

For reference, I have no heat damage, bleach damage or anything like that... all of my hair is completely virgin, but I probably had some chlorine damage + mechanical damage. I felt a noticable difference after first use and the difference is permanent - as permanent as anything can be, of course, since there is always new damage happening to the hair (even if you are careful).

Would I recomend? Perhaps. I won't care to use this after I reach my goal lenght. It's too expensive, and as long as my hair looks nice and I can trim again when maintaining, I don't think I need this. But this can certainly help on the way to goal lenght if you are a non trimmer or want to trim rarely.

I really appreciate your post, SeppV. Thank you. I think I'll try it! My hair is currently about BSL or just above.

[SeppV]

Hope you get good results! I usually part my hair by two or four when I use this, just to be able to use a tiny bit at a time, a little product goes a long way, but not if you blob it all on your hair at once.

Not a chance that I would pay this much money and put in my hair something that has alcohol this high on ingredient list :eye:
When in doubt always read INCI first;)

I don't quite understand what you meant by your comment, I might have a hard time reading English after a night of sleep training with a baby! But, I wanted to comment on the alcohol denat bit. They explain that on their website, since people (with good reason!) will react. Here is how they explain it: "Denatured alcohol is used in K18 formulas to open the gates for our peptide to reach hair’s damage sites" Which makes sense, but this is also the reason I only use it about once a month. It does have excellent results. I don't doubt their cleverness in this product. Usually I use drug store products. I don't care to put too much money into my hair care, but for some reason I got fooled into this.... and I will gladly spend the bottle.

So I used it once last year on hair that has been bleached and dyed.

Didn't really do anything.

I think my usual products (Alfaparf semi di lino for dry hair) keep my hair in really good condition so there wasn't much for the K18 to do. my hair was also shoulder length so probably not as much damage to the ends as if it were longer.

Idk, I didnt notice a huge difference on myself.

I used it back when I had a bob that was bleach damaged. I didn't notice any significant improvement. If anything it made my hair feel a bit dry.

I've been using it probably 4 times? And I'm seeing a difference in my ends. I definitely like it.

[BlushingRose]

I used it pretty religiously when I bleached my hair and definitely noticed a difference. I did platinum and changed fashion colors which meant I was continuously doing bleach washes over the years. I still have some bleached length and ends that I swear would've broken off by now if I hadn't used bond builders, and they are mostly as silky as my virgin growth except the tips. It's expensive but better than Olaplex and a bit less annoying to use too (imo) I think it's good investment if you're going to have chemically treated or heat styled hair.

I really am curious to try this too but if it did nothing it would suck

[SeppV]

I used it yesterday again, I use it every third or fourth week. Great results, as always. This has really helped my ends stay nice for the past seven no-trim months. It's not a hair mask in the regular sense, but it's repairing damage, so if I don't re-wet my hair and apply conditioner after the four minutes this is supposed to be in, I will get really flat, static hair (but shiny and in a better state, of course). Maybe some people get dissatisfied because they don't understand the concept... (not discrediting the fact that it might notwork for every one, though), But for you, Bat, with coloring and bleach damage, I woyld expect it to work really well! I rave about this product so much because it really changed my hair for the better, with lasting results.

I'm going to get a trial size when my Olaplex 3 runs out! I figure it can't hurt.

The trial size should last you a few washes if you are really careful distributing the product! It lasted for about four washes for me, and I had hip lenght, medium thick, hair at that point.

That's what I did and it lasted me several weeks. I liked it so much that I bought the larger size next.

I also tried Olaplex, but I don't like their products.
