I Thought K18 Was Just A TikTok Brand – Then I Tried It

My hair is damaged but I literally do not care. For me expression always comes first, so even though I know it’s supposed to be stronger + softer.…it hasn’t stopped me from experimenting with my hair.

I adore styling my curtain bangs with big 70’s waves, then going stick straight. Basically for as much as I change my mind, I also put my hair through equal amounts of damage. This year, I even bleached my front pieces and the underside of my hair to add some fun colors like purple and green.

When I asked my stylist what it would take to go platinum blonde, she told me it’d be much easier if my hair was healthier. With all that I put my hair through, I thought I’d reached the end of the line–time to chop off all my hair and start over–when she recommended I try the K18 leave-in molecular repair hair mask.

I couldn’t imagine one mask was going to fix what I had going on, but she said the biomimetic technology is next-level to anything she’s ever tried before.

I’ll try anything, but the $75 price tag was daunting. But K18 has a $29 travel size option and a $12 try-it size option. Plus, thanks to the highly-concentrated formula, the full-size hair mask contains dozens of doses per bottle. When you break down each use as a salon-level treatment, it’s a steal!

The product seemed suspiciously good–cruelty-free, vegan, and they claim the leave-in treatment repairs damage from bleach + color, chemical, and heat damage. Best part, it only takes 4 minutes!

I happened to be scrolling TikTok when I saw someone raving about their amazing results and how easy it is to use. When I started digging through #k18hairflip, I found a ton of positive reviews on all hair types. I decided to get the full-sized version, just to see what happened.

It arrived in a cute little box with a canvas bag along with instructions. I hopped in the shower and used just my regular shampoo–skipping conditioner felt strange at first, but it helps the K18 mask penetrate better. And then when I got out, I towel-dried my hair and smoothed 1 pump from my ends to roots, adding more of the mask as needed (I ended up using 2 pumps for my whole head). You wait 4 minutes (back to my Instagram feed I went) before applying any heat or styling product.

I gave my hair a blow dry, and felt like I’d stepped back in time; my hair felt so much stronger and softer! You’re supposed to use the K18 mask every wash for the first 4-6 washes, and then move to maintenance mode with use every 3-4 washes. But, there was such a noticeable difference after just one use! I was so impressed—never had a product promised this much and actually delivered.

I think the science behind it impressed me the most. K18 uses patented peptide technology to reconnect broken keratin chains in the inner-most layers of hair, traveling further than most repair treatments that merely sit on top of hair. So instead of my hair just looking and feeling healthy, K18 made my hair’s core structure healthy!

Despite continuing to heat damage my hair with blow dryers and curling irons, my hair got better with each use. I snapped a pic to my stylist, who told me if I wanted to go platinum this year, she could now make it happen!!! Plus, my stylist can use K18 in the salon to repair my hair damage right after it happens.

I feel like I’m cheating. I can do (almost) whatever I want to my hair. And with K18, I’m no longer afraid of damage.

If you love to express yourself with your hair, K18 is an absolute must-buy for lasting repair on all hair types!
