Key benefits:

• Deeper damage repair – 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.
• Immediate and lasting results – hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits.
• No rinse, leave-in convenience - convenient, leave-in formula works in just 4 minutes, with no extra rinse required.
• Effective on all hair types – because K18PEPTIDE™ targets on a molecular level (where all hair is the same), it works for straight, wavy, curly, coily, fine, thick, or chemically-treated hair.

How to use the K18 Hair Mask: Shampoo, do not condition. Towel-dry thoroughly. Apply 1-3 pumps depending on your length and density, starting at the ends and working up towards the roots. Let sit for 4 minutes. Do not rinse out. Comb, add product + style as usual.
