Healthy hair exhibits several characteristics that indicate its vitality and strength. Shiny, smooth, and elastic hair reflects good moisture retention and proper care. When hair is shiny, it typically means that the cuticles are lying flat, allowing light to reflect off the strands, which also indicates that the hair has a healthy amount of natural oils. Smooth texture suggests that the hair is free from damage such as split ends, tangles, or rough patches, which can interfere with the hair's overall health. Elasticity is another important factor; hair that can stretch and return to its original length without breaking is a sign of resilience and strength.

In contrast, dull and brittle hair shows signs of damage and dryness, meaning it lacks moisture and may have been subjected to harsh conditions or treatments. Thick and coarse hair can be healthy, but it doesn't automatically indicate good health; it may also be lacking moisture or be prone to frizziness. Oily and weighed down hair usually indicates an overproduction of oil, possibly from inadequate washing or heavy products, which can lead to an appearance of uncleanliness and can also suffocate the hair, making it unhealthy. Thus, the characteristics of shiny, smooth, and elastic hair are the true indicators of health and vitality.
