Which hair treatment aims to repair damaged hair cuticles?

The aim of protein treatments is to repair damaged hair cuticles because they contain hydrolyzed proteins and amino acids that penetrate the hair shaft and strengthen the hair structure. When hair is damaged, such as from chemical processing, heat styling, or environmental factors, the cuticles can become compromised, leading to issues like frizz, breakage, and lack of shine. Protein treatments work by filling in the gaps in the hair cuticle, effectively reinforcing it and improving the hair's overall health and resilience.

While color treatments focus primarily on altering the hair's appearance and may not address the underlying damage, moisturizing treatments generally aim to hydrate and improve softness rather than directly repair the cuticle. Oils and serums can provide shine and reduce frizz but do not necessarily repair the structural integrity of the hair. Thus, protein treatments are specifically designed to target and mend the damage at the cuticle level.
