K18 will bring your damaged hair back to its original state, and it is now at K Bella! This product uses a K18Peptide, which is clinically proven to reverse the damage caused by bleach, chemical services, and heat in just 4 minutes! They pinpointed one unique bioactive peptide that helps to fix damaged hair. When hair is damaged, the keratin chains that make up the inside of hair strands become weakened and break. There are billions of keratin chains inside one single strand of hair, and when they become compromised, the hair loses its strength, elasticity, resiliency, and shine. The K18Peptide is the perfect size and makeup to reconnect those broken chains. This peptide also re-conforms any disturbed disulfide bonds in the process. Repairing these connections is what restores your hair's strength and elasticity. K18 is a serious game changer in the hair world, and we are so excited to help you get your hair back to its healthiest state!
