I’ve been going to the salon to touch up my roots and maintain my blonde color every couple of months for at least five years. When I first went blonde, I felt invincible – a dramatic change that helped my hair finally look as fun and free as I feel. But, over time I’ve become less confident in how my hair looks.

It’s fried from all the bleaching and toning I’ve done over the years. A few days after the salon, the conditioning treatments wear off and the frizz comes back in full force. Beyond appearance, my hair is now so weak that the breakage leaves me with strands falling out in the shower and in my hairbrush.

My hairstylist has also been noticing it and we’ve tried all kinds of products to get my hair back to healthy… but nothing worked. I was about to give up my beloved blonde look just I could repair the damage until she came to me with the K18 Leave-In Molecular Repair Hair Mask.

She had seen the Hair Mask on social media and decided to test it out. Here’s what happened when she compared it to another leading bond builder:

My stylist has been by my side through all my hair hits and misses, so when she recommended using K18 and showed me these results, I knew it was the way to go. I can’t believe I’ve been feeling insecure about my bleached hair for years when K18 is out there.

While K18 sells to salon professionals, she told me I could buy my own Leave-In Molecular Repair Hair Mask to use at home. I was skeptical about the cost at first. A single full-size 50 mL bottle costs $75 but based on how terrific my stylist made my hair look, I gave it a shot.

Out of all the hair masks and treatments I’ve tried, this is by far the best. All the other products added so much time to my routine, while K18 takes only 4 minutes! It’s simple: simply wash with shampoo, towel dry, and apply a pump of the Hair Mask (how much you need depends on the length and thickness of your hair).

One pump was enough for me and after giving it 4 minutes to activate, I was good to go. There’s no jumping in and out of the shower to rinse, and after one use I saw an immediate difference. My hair is shinier, bouncier, and even feels stronger – all while getting to keep that beautiful blonde color I love.

I can’t believe that K18 reversed years of damage. Their K18Peptide™ repairs the hair at a molecular level with science-backed research, reconnecting broken keratin chains within the strands.

After using it for 6 consecutive washes, I was able to switch to applying every 3 or 4 washes for maintenance. The full-size product really does last thanks to their concentrated formula being so effective with a single pump. I’m getting professional, salon-quality treatment at home and my hair couldn’t be happier.

If you want to keep bleaching your hair, you need to try the K18 Leave-In Molecular Repair Hair Mask. The results speak for themselves, trust me.
