Leave-In Molecular Repair Hair Mask, 4-Minute Speed Treatment, Renews Hair Damage From Color, Chemical Services Heat

 

 


A leave-in treatment mask for all hair types that clinically reverses damage in 4 minutes. The patented peptide technology works to repair damage from bleach, color, chemical services & heat – restoring strength, softness, smoothness, and bounce to hair.

creates hair like new
Traveling deeper into the inner layers of hair than traditional repair products, our revolutionary patented K18Peptide™ is just the right size and makeup to fit in and reconnect broken keratin chains, renewing hair with strength, softness, smoothness, and bounce. You can feel and see the difference with the first use.

See dosage chart for exact usage. For best results, use for the first 4-6 consecutive washes, then every 3-4 washes as needed to maintain hair strength.

IN the shower

  1. Shampoo, do not condition.

OUT of the shower

  1. Towel dry thoroughly.
  2. Begin with 1 pump of the K18 Mask and add more as needed depending on the length, thickness, and condition.
  3. Work evenly into hair from ends to roots, one pump at a time.
  4. Let sit for 4 minutes to activate.
  5. Do NOT rinse out.
  6. Style as usual


    • DO use a clarifying shampoo if you’re a heavy product or dry shampoo user to remove buildup and help our peptide penetrate and get where it needs to go.
    • DO wait the full 4 minutes before styling or applying other product
    • DO use every 4-6 shampoos consecutively to see and feel ongoing results
    • DON’T condition your hair before application (trust us, most won’t need it after K18, if you still need, add a leave-in after the 4-minute window is up post-application)
    • DON’T overuse, a little goes a long way.
    • DON’T rinse out. This is a leave-in, so you know, leave it in

      Our K18Peptide™ is clinically proven to reverse damage in just 4 minutes.

Arrived Fast! And Authentic

I was very skeptical buying off a not well known website, I called them up and got convinced.
because they offered me free expedited shipping!
It arrived the next day. I am very happy that It is Authentic.
I am now recommending my hairstylist to buy this product from here because it is $5 cheaper than amazon.

K18 Review

I’m taking better care of my hair, stopping bleaching 3-4 months before due to chemical cutting. Masks every sulphate/paraben free weekly wash, leave in conditioners, heat protectants etc., I see this as an addition to the current market lead number three. The tube is tiny, I have thick hair 2” above my shoulders. I wore gloves to help K18 go further. You wash but not condition, towel dry with your micro-fibre turban and run it through your hair. After 4 mins style as usual. Hmmm my hair after was a bit stiff and dull…so I have just washed it today day 2 and it’s soft again. For a tenner you get 2 maybe 3 at a push 10p sized amounts. It’s over priced but promises big things! You already know that I cut open the tube so as to get it all. As I said my hair was compromised so the small improvement maybe is all I can expect?. I think I need a bigger bottle for repeated treatments. If I do I will return here to tell you x

Game changer

I don't normally write reviews unless I'm absolutely blown away. I saw a couple of negative reviews on here but I purchased anyway after watching some videos on YouTube and I wasn't disappointed. A few days ago I went from brown to blonde at home. As you can see in the picture to the left (and that's before I processed it again with a toner) as you can see there's damage...I knew there would be going back to blonde. The picture to the left is 2 days ago. This morning I shampooed my hair twice with a clarifying shampoo, it's important to really shampoo and to NOT put any conditioner on. Towel dry. .. always gently squeeze the water from the hair with the towel,never rub the hair with a towel when drying. I understand some people will find it hard to not condition but if u stand up in the shower when washing it and dry your hair this way your hair shouldn't be tooo tangly, when you have removed as much excess water as you can apply a SMALL amount... the package has a guideline for the length of hair. I used a pea sized amount and I did think it couldn't possibly be enough but TRUST THE PROCESS! I combed through and left it on probably 10 mins (it says atleast 4 minutes) do not wash it out , after the initial 4 mins you can add styling products, I used a conditioning and heat protecting spray before blow drying. I can't get over how good my hair feels after 1 use, it feels better then pre bleaching, I honestly can't wait to wash my hair again! I will be buying the full size bottle, yes it's expensive but it's insurance for your hair. Its just over 50 pounds on their site for 50mls... that's like a pound per ml and I think i will use 1 ml per use... that's 50 uses for my length hair. I never had results like this with olaplex! I definitely recommend you try the sample size, follow the instructions and you will get a couple of uses...I think I will have 4 uses. This has to be one of the best things I've brought!

GOOD LORD I LOVE IT

Today I received this product today, I’ve been wanting to try it, do I bought the sample size, that I’ve been really wanting to try. I read the directions, and it say ‘ use on shampooed hair, DO NOT CONDITION.’ I spoke to this 1 ounce tube in my hand…’ I’m terrified, I have curly hair and you said do not condition.’ Anyone with curly hair will understand this inexplicable fear that coursed though me. I’m trying it out tomorrow, please send me all the good energy, I’m going to need it to see me through this no conditioning phobia

***Update***
So….my hair didn’t feel like a straw tangled mat on my head. Feels like it would if I had conditioned it. I think I will actually buy the full size product. My hair feels better after one use than after several uses of Oliplex
