What is often a sign of healthy hair?

Shininess is often a sign of healthy hair because it indicates that the hair cuticles are smooth and well-aligned. When hair is in good condition, it reflects light effectively, producing a natural shine. This shine is characteristic of well-moisturized hair that retains its natural oils, which not only contribute to the aesthetic appearance but also protect the hair from damage and environmental factors.

In contrast, dryness and brittleness typically signify that the hair is lacking moisture and may be damaged or over-processed. Frizziness is often the result of hair that is porous and unable to retain moisture, leading to an unmanageable appearance. Healthier hair tends to be smooth, well-hydrated, and free from excessive damage, all of which contribute to its shininess.
