Why is moisture important for chemically treated hair?

Chemically treated hair undergoes significant changes in its structure and composition, which can often lead to a loss of moisture and elasticity. Moisture is crucial for maintaining the hair's elasticity because it allows the hair strands to stretch and return to their original shape without breaking.

Chemically treated hair tends to be more porous and susceptible to dryness, which can compromise its strength and flexibility. When hair is well-hydrated, it has a better ability to withstand styling and manipulation, reducing the risk of breakage. Having adequate moisture in the hair helps to retain its natural bounce and resilience, essential for maintaining healthy-looking hair after being subjected to chemical processes such as perming or relaxing.

While other factors like volume, detangling, and color retention are significant in hair care, they are secondary to the primary need for moisture to ensure the hair remains strong and elastic, particularly after chemical treatments.
