K18 Biomimetic Hairscience Leave-In Molecular Repair Hair Mask, 5 ml

I was having doubt about this product but after I tried it's worth the price. I bought this small amount to try first. I have bleached damaged dry hair. This product is amazing. Leaves your hair restored smooth and not heavy with the nice volume. Small tube it is comfortable for traveling not just testing. Superb product!

I wish I'd taken a before photo .I have been using £40 quid salon masks and shampoos and serums and nothing has been working to revive my fine, fried multi -bleached over- processed and breaking hair.I bought the sachets of Aphogee protein treatment on here a fortnight ago ,which was incredible and definitely helped stop the breaking and did make my hair feel and look so much better.I wanted to use it again because 2 weeks later my hair was back to looking flat and damaged,but but was advised not to due to 'protein overload' .I've been obsessed with finding a miracle since an expert hairdresser advised that my only solution was to get a pixie which I can't face ,as it took me 4 years to grow out my last short cut due to bleach damage to almost shoulder length but I just had to cut 4 inches off to disguise all the recent breakage from a semi permanent (that was not supposed to be damaging ) I bought this after tons of research and since it is only £6 I felt had nothing much to lose . The tube is teeny but I read that you only use a pea sized amount .In 5ml there is at least 4 applications left . The results have been ASTONISHING .Suddenly I've got my pre -dyed teenaged big hair back .It looks longer probably because of the fullness ,it looks like completely different hair.. I did use leave- in conditioner ( Peurology) after the initial 4 minutes , though it says not to use conditioner afterwards .It's shiny and has gone big and woofy with minimal styling and feels soft,I can barely feel the fried parts anymore and it's just doing all the right things Tell me kind of witchery is this !? I really hope results last .

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 was amazed at how ths product seemed to repair my curl pattern after the first use. I continued as directed for a further 5 washes and all was good. I intended to do as directed and use it as maintenance every 3rd wash . But the very first hairwash without it made my hair return to the frizzy mess it was before. I surmise that the effect of this product is only valid whilst it is in use after every wash and that the effect is simply a temporary fix. Extremely disappointing considering all the hype and the vastly overpriced cost of the product.

My hair felt gorgeous after using this, the curls were more defined and then once straightened was lovely and silky (I have type 3c/4a mixed afro hair). I have thick hair also and this bottle just about covered it, could maybe have done with a second one for good measure but overall good results!

I have been thinking about K18 for months, but the steep price was putting me off.However after breakage due to bleaching so bad I’m almost bald on the right hand side (please don’t use 40 volume peroxide even if you’re dark! Do twice 20 but don’t go nowhere near 40 🥺! Anyway…) I decided to give it a go since I was literally browsing for pixie cut hair whilst balling my eyes out (no, it’s not just hair when it’s falling off, trust me! ) and OMG .You can literally feel your hair getting better as you apply the K18 in your hair.I’ve been told it’s miracle stuff before, but I was disappointed with Olaplex so I was sceptical.It really is miracle stuff! I’m so happy I got 3 more straight away.If your hair is ruined and you think it’s beyond saving, it’s probably not if you try this.

This is the worst product I have ever used. Had hair done on Monday (no issues) , went to use this today (Friday) and it has made my hair stretchy and snapped it.

It is a pity it is sooooo expensive… because I have a very long hair 😒 The product is amazing
