What can be inferred about the relationship between hair elasticity and damage?

Higher elasticity indicates healthy hair because it demonstrates that the hair strands are resilient and can stretch without breaking. Healthy hair is typically more capable of returning to its original shape after being bent, twisted, or pulled. This elastic property shows that the hair cuticle is intact and the inner structures are functioning well, allowing the hair to endure stress without sustaining damage.

In contrast, lower elasticity often signifies that the hair has suffered some level of damage, such as from chemical treatments, excessive heat styling, or environmental factors, leading to brittleness and breakage. Therefore, the relationship between elasticity and hair health is significant, and high elasticity is indeed a positive indicator of overall hair condition.
