I haven’t been on a plane in what feels like years, but I have a vacation coming up and I am so excited! Packing has always been stressful for me, especially if I’m confined to a carry-on. My beauty regimen is so important to me, but most of my products either take up too much space in my luggage or exceed the 3 ounce TSA limit!

My hair is really frizzy and unruly after years of abusing it with hot tools and hair dye. Hotel shampoo and conditioner definitely won’t cut it for my heat + chemical damaged hair! I went to the mom blogs in desperate hope to find a solution that would simplify my hair routine and bring my fried hair back to life for the strength and softness I had years ago.

The recommendations kept pouring in for one; the K18 Leave-in Molecular Repair Hair Mask. I’d heard of it but doubted that one product could replace everything I use. So I checked out their website and found out that their patented peptide is clinically proven to reverse hair damage from bleach + color, chemical services, and heat. Best part, it does it all in just 4 minutes—so I can spend less time perfecting my hair, and more time enjoying my vacation.

Plus, my big family is all staying in one Airbnb, so downsizing my hair routine with K18’s mask would help preserve counter space in the bathroom, and my suitcase.

Out of their three sizes, I went with the 50ml mask since it was the best value (and is still TSA-friendly!) For trips with just my carry-on, the travel size mask would definitely come in handy. Plus, K18’s highly-concentrated formula means a little goes a long way—so this tiny-but-mighty mask will last longer than you think. Here’s how I put it to the test!

Here’s how to use K18 in any hair routine:

  1. Clarify before your first use + skip conditioner (it will block the peptide from getting where it needs to go). Don’t worry, if you want you can add a leave-in at the end!
  2. Towel-dry your hair ‘til damp, then apply 1 pump to your hair. If you missed some strands, add ½ pump more at a time. Average use is about 2 pumps (yep, that's it!)
  3. Leave it in (no rinse needed); just wait 4 minutes before combing + styling as usual.

Start by using K18 after the first 4-6 washes, then switch to maintenance mode to renew hair when needed. The patented K18Peptide™ is just the right size + molecular structure to reach the innermost layers of hair, reconnecting broken disulfide bonds (what bond builders do) AND broken keratin chains, which are responsible for hair’s core strength + elasticity. Now that’s next-level damage repair!

After a quick blow-dry, I was impressed! There was absolutely a noticeable difference in the texture of my hair - even without my expensive conditioner, hair mask, and detangler!

For my trip, I packed shampoo, K18, and a little texturizer. The process of doing my hair became so simple and efficient, and I didn’t miss lugging around that huge bag of toiletries.

K18’s Leave-In Molecular Repair Hair Mask works for all hair types, so do yourself a favor and try K18—at home or on the go!
