K18 x Future Society leave-in molecular hair mask

Making the impossible possible in haircare and scent with biotech.

K18's biology-first molecular hair repair mask, powered by the patented K18PEPTIDE™, has the right size + molecular structure to repair multiple types of bonds at the molecular level. It works in just 4 minutes*—delivering immediate + lasting strength, softness, smoothness, and bounce for all hair types.

In collaboration with Future Society, this limited-edition scent is inspired by extinct flower DNA, and brought back to life with biotech. Floating Forest is a cool aquatic floral scent, rooted in an extinct rainforest tree once found only in Borneo.

• Reverses damage in 4 minutes* to restore strength, softness, smoothness + bounce
• Immediate + progressive results*
• Limited-edition scent

In the shower:

• Shampoo, don‘t condition.

Out of the shower:

• Gently towel dry hair until damp.
• Apply one mL/one dime-sized amount of K18 Mask.
• Only add more as needed. Average use is two mL/two dime-size amounts (this is a highly concentrated formula, so you‘ll need much less than traditional masks).
• Work evenly into hair from ends to roots.
• Wait four minutes for the K18PEPTIDE™ to reach the innermost layers of hair
• Don‘t rinse out.
• Style as usual after the four minutes is up (fine to add heat protectant or styling product now).
• Use for the first four to six washes, then swap to maintenance mode and use as needed.

• DO clarify before K18 if you’re a heavy product user (demineralize for mineral + metal buildup).
• DO apply on clean, damp hair.
• DO wait the full 4 minutes before combing or styling.
• DO add whatever styling products you love after the 4 minutes.
• DO use for 4-6 shampoos consecutively for progressive results.

• DON'T use conditioner before applying K18 Mask (you can apply after the 4 min but most find they don’t need it).
• DON'T overdo it—less is more.
• DON'T rinse it out.
