When hair is damaged, its molecular structure, composed of peptides, becomes compromised. This can lead to hair breakage, excessive elasticity, and a lack of movement. The challenge is that most peptides are too large to be effectively reinjected into the hair fiber, making the damage almost irreversible.
However, through its advanced research, L'Oréal has achieved a breakthrough. They have developed a process to decompose peptides into their individual components, allowing them to be separately injected into the hair fiber.
