key benefits
- Reverses damage in 4 minutes* to restore strength, softness, smoothness + bounce
- Immediate + progressive results*
- Limited-edition scent
Takes damage repair further – reconnects both polypeptide chains (and as a result, also reconnects disulfide bonds) for strength along the length + width of the hair - offering comprehensive, lasting damage repair
Restores hair from even extreme damage - by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair
Delivers immediate and lasting results – hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits
Simplified repair - convenient, leave-in formula works in just 4 minutes, with no extra rinse required
Works on all hair types – because K18PEPTIDE™ works on a molecular level (where all hair is the same), this product is effective on all hair types
how to use
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's + don'ts
- 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
