got a question?

Less is more, so don’t overdo your K18 mask appllication. This highly concentrated formula was made to use way less than your traditional hair mask or conditioner. Start with 1 ml (1 pump of the 50ml mask, 3 pumps of the 15ml mask) and massage the product between your palms until the product thickens. Add more as needed, the maximum recommendation is 3ml (3 pumps of the 50ml mask, 9 pumps of the 15ml mask).

Think of K18 mask as a highly concentrated treatment. It restores hair’s strength + elasticity in the innermost layers of hair, instead of traditional conditioners that coat the outside of hair. Skip conditioner before applying the K18 mask so it has a clean canvas to penetrate into the innermost layers of hair. After the 4-minute wait time post-K18, feel free to add a leave-in for a boost of conditioning if needed.

Swap your regular shampoo for this power wash once a week or as needed. No matter your hair type or product routine, a regular detox shampoo is essential to remove buildup, reset texture, and maximise the performance of treatments and stylers — like K18 molecular repair.

The detox shampoo combines activated charcoal to absorb toxins, excess oil, and dirt from hair and scalp with salicylic acid to clear sebum buildup in follicles—without stripping essential moisture and lipids. Our patented K18PEPTIDE™ helps reduce protein loss, keeping hair feeling healthy and strong with every wash.
