After spending a decade in the lab scanning and testing all amino acid sequences across the entire keratin genome that makes up human hair searching for a breakthrough, we discovered one unique sequence (a bioactive peptide) that brings damaged hair back to its original, youthful state. This is our K18Peptide™.
Traveling deeper into the inner layers of hair than traditional repair products, our revolutionary peptide is just the right size and makeup to fit in and reconnect those broken polypeptide chains (keratin chains). And because our peptide is a bit of an overachiever, as a result of this reconnection, any disturbed disulfide bonds are also re-conformed.
Our peptideemploys biomimetics to get the job done. To put it simply: Biomimetics is the practice of learning from and mimicking nature. Mimicking the natural structure of keratin building blocks (amino acid sequences), our K18 bioactive peptide is recognized as natural by the hair. It’s not washed away by water or shampoo like traditional bonding agents either, making K18 a genuine, lasting solution for damaged strands.
An Analogy: When building proteins, the order of the amino acids determines the kind of protein and its properties, much like the way letters are arranged to make meaningful words and sentences. In the same way the order and where each word sits in a sentence leads to its overall meaning, K18 is the magic word that fits right in, integrating itself with the keratin chains as the hair recognizes it as a natural building block.

I have not been able to find a product that does anything remotely close to this. Repairs damage and just brings my curls back to life. Pics are before, after one use, then after 2 uses and it just keeps getting better. Plus I touch my hair all day and it’s lightweight and not sticky.

I bought my first bottle at HongKong Sephora back in March. I wasn’t sure how good it’s gonna be since I was recommended by AI. I have thin/fine hair, and I bleach it to blonde every 3 months. I always had a hard time growing my hair long cause it’s so damaged. Nothing I tried worked!!!! Not even the products recommended by my hairstylist.
