Leave-in Molecular Repair Hair Mask - Treatment for Damaged Hair

Amazing!

Works miracles ! Only thing that has tamed my dark hair since lightening it. You have to make sure you take a pea sized amount and rub it in your hands till it turns white before applying!

Rejuvenates perimenopausal my hair

I’m 54, have lots of fine wavy longer hair that I color and also have existing gray in. Many different textures on one head of hair! I did use the first restructuring product on market for years but find K18 works better on my hair. I did need to experiment- using it as leave-in after shampoo as directed without any emollient conditioner was horrible in my hair. Dry, tangled and stiff once dry (I only air dry.). I almost threw the bottle out but now I’ve figured out secret for my hair. I shampoo first then finger comb K18 thru and leave on recommended minutes. Then I wet my head again and use my regular conditioner like usual. Never dry it, comb with wide tooth comb then gently twist and wring it dry and then air does the rest. My hair texture and wave pattern then resembles what it looked like years ago before all the perimenopausal changes started! I maybe do this once a month, wash/condition every 4 days.

Really works!

I noticed a big difference in th condition of of hair, softer and smoother, after using it once a week for a month

Will BREAK off fine hair - use with caution

Do NOT use this product if you have thin bleached hair. I have noticed my hair get progressively weaker in the last year and now realize it is due to the K18 line and packing too much protein into my thin strands. It made my hair feel so strong and soft after first using but then tripled the amount of hair falling out in the shower. I don’t normally write reviews but I saw so many others people writing about this on reddit that I wanted to make sure I put my review on here - it broke so much of my hair off and slowly weakened my hair do NOT use if you have fine hair you will thank me later!!!

Glad I Tried

I bought this during the last Beaty Insider event…don’t know why but I’m glad I did. I have fine, straight shoulder length hair and the hair in the front on my right side is always frizzy no matter what I have done. I use 1 pump and work it through my hair with my fingers then brush. I wait the 4 minutes like the directions state, then I either air dry or blow dry. Et voilà! No more frizzy hair.

Amazing

I have fine color treated hair with highlights that tends to get frizzy and dull looking. Purchased this product for the first time. I use it once in a while and it never disappoints me.

I have used it as prescribed. It is not conditioning/repairing at all for me, I have coarse, color treated dry hair. It has to be used after shampoo and towel drying. They're supposing you are using some heavy-duty leave-in conditioner after (you can't condition before you use it). That's a step I can usually skip thanks to deep conditioning in the shower. But even with leave-in conditioner it leaves the hair a little stiff, a little dry, a little wiry. I get better results with shampoo + deep conditioner or mask in the shower. The Olaplex N.3 is such a pain to use because you have to do it (for 8 full minutes) before you even shampoo, but you can see the results from the first use and without changing anything else to your routine. It's too bad because I was hoping this would work, the flow seemed easier. Back to Olaplex.

Excellent unique product for medium fine wavy hair

I love this mask. I have been using it off and on for a couple years now, this mask has helped my curls come all the way back. It will help your natural texture come back after using for a while

Great hair mask

Great mask for bleached / dry hair. Highly recommend

Little miracle for someone who bleaches their hair

Surprised it worked so fast! I have seen a massive change to my hair in texture and feel. It has really helped massively in restoring it fully. I was hesitate, but will definitely be repurchasing a bigger size

You won’t regret it

I love it. I notice less damage. It makes my ends healthier But it’s expensive

Does not work at all it makes your hair messy and frizzy
