The verdict
K18 Leave-In Molecular Repair Hair Mask
50,000+ bought last month
Size0.51 Fl Oz (Pack of 1)
TOO EARLY.
This is a leave-in hair treatment you apply for 4 minutes after shampooing to repair damage from bleaching, coloring, heat, or chemical treatments. It uses peptides that work inside the hair structure rather than just coating the surface, so it's meant to actually rebuild damaged strands instead of just making them feel softer temporarily.

The read
What's actually worth knowing.
- You skip conditioner and don't rinse it out, so it's a different routine than a typical mask. The idea is that the peptides stay in your hair to keep working.
- It's a small bottle at 0.5 fl oz, so you're getting a concentrated product that goes a long way with just a few pumps per application.
- Results typically show up after a few uses rather than immediately, even though the treatment itself only takes 4 minutes to sit in your hair.
