What is one key characteristic of healthy hair?

Healthy hair is characterized by being smooth, shiny, and elastic. These traits are indicators of well-nourished hair that has not been damaged by excessive heat, chemical treatments, or environmental factors. Smoothness allows hair to withstand elements without becoming overly frizzy or rough, while shine reflects light, indicating that the cuticle layer is intact and well-aligned. Elasticity indicates that the hair has the ability to stretch and return to its original shape without breaking, showcasing its strength and health.

In contrast, hair that is dull and brittle suggests damage and lack of moisture, while being easy to tangle indicates weakness or rough cuticle layers. Split ends are a common sign of dry and unhealthy hair, indicating that the hair shaft is fraying and in need of care. Overall, the presence of smoothness, shine, and elasticity is a clear sign of healthy, robust hair.
