At-home hair oil for improving hair quality. It forms a chemical bond (amide bond) with the amino groups of hair keratin through heating, resulting in greater hair retention than hydrophobic interactions, and strengthens the hydrophobic properties of the hair surface and interior. Contains original active keratin ingredients. In addition to suppressing damage, it also repairs damage effectively. Brand new, unused, unopened. The outer plastic wrap is also still on. I am selling it because I no longer plan to change my hairstyle. Hair care Keratin Damage care High tone Bleached hair Damage repair
