What is an indicator of healthy hair?

A shiny texture is a key indicator of healthy hair because it reflects light effectively, which means the hair cuticles are lying flat and intact. When hair is healthy, it has a smooth surface that allows it to capture and reflect light, resulting in a shiny appearance. Shiny hair indicates that it has adequate moisture and is well-maintained, free from excessive damage such as split ends or brittleness.

On the other hand, dull appearance, frizziness, and brittleness suggest that the hair may be damaged or lacking in moisture and nutrients. A dull appearance often indicates that the hair is dry or lacking in essential oils. Frizziness can be a sign of hair that is not properly hydrated or is in poor condition, while brittleness indicates excessive damage, often leading to breakage. Thus, a shiny texture serves as a direct indicator of good hair health.
