How does the K18 mask work?
The K18 Mask works as a treatment to reverse damage in 4 minutes. It’s powered by our biomimetic K18PEPTIDE to seamlessly fit in and reconnect broken polypeptide chains at the molecular level.
What is the K18PEPTIDE?
K18PEPTIDE is a biotech-developed peptide that mimics hair’s structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during damage from bleach + color, chemical services, and heat.
Why skip conditioner?
Conditioner leaves a film that blocks our peptide from penetrating effectively. Once the 4-minute wait time is up, feel free to use a conditioner, a leave-in, or any type of product.
I noticed there’s alcohol in the formula, isn’t that bad for you?
We like to keep our formulas minimal, only using the exact amount of ingredients needed to get the peptide where it needs to go. Here the alcohol serves as an agent to optimize the hair environment for the K18 Mask to work on a deeper level.
When should I expect to see results?
Most see results after 2-3 uses. The more damaged the hair, the more dramatic the results so it may vary depending on your hair type and level of damage.
