K18 is a groundbreaking product for repairing damaged hair, as well as bringing naturally dry or frizzy hair a polished and healthy finish. Long term use promotes stronger healthier and smoother hair. 

No doubt this is a luxury product and not necessary for everyone. We recommend it mostly for anyone with chemical damage, chronic hair breakage, or anyone who losing the lifelong battle with frizz. 

A leave-in treatment mask for all hair types that clinically reverses damage in 4 minutes. The patented peptide technology works to repair damage from bleach, colour, chemical services & heat – restoring strength, softness, smoothness, and bounce to hair.

The K18PEPTIDE™ works at the innermost layer of hair, reconnecting polypeptide chains and disulfide bonds broken during bleaching, chemical services, and through heat damage.

By addressing these damage sites at the innermost layer of hair, core strength and elasticity are renewed for strong, smooth, bouncy hair—even after the most extreme damage done in the salon or at home.


  1. Shampoo, do not condition.
  2. Towel-dry thoroughly.
  3. Begin with 1 pump of K18 mask and add more as needed depending on length, thickness, and condition. Work evenly into hair from ends to roots, one pump at a time, maximum dosage is 3 pumps.
  4. Let sit for 4 minutes. Do not rinse out.
  5. Then comb + style as usual (fine to add heat protectant or styling product now).
  6. Use for the first 4-6 washes, then as needed

5ml sampler - gets 4-5 uses on fine hair, 3-4 on average hair, 2-3 on thick or long hair

15ml - is a great intro size which will get about most people about 15 uses. A good basis for finding out if its right for you, without breaking the bank. 

50ml - lasts the average person 4-6 months of semi regular use (depending on frequency of washing) 

150ml - is a 12-18 month investment.  We recommend this size for anyone who has used the 15 or 50 ml bottle and was convinced of the positive impact on their hair, as it has the best price to volume ratio.
