Which of the following is a sign of healthy hair?

Healthy hair is characterized by several key traits, one of which is being free from split ends. Split ends occur when the hair cuticle splits, often due to damage from over-processing, heat styling, or environmental factors. When hair is healthy, its cuticle remains intact, which allows for moisture retention and strong, resilient strands. This integrity promotes a smooth texture and shine, indicating that the hair is not only healthy but also well cared for.

The presence of split ends suggests that the hair may be undergoing stress or damage, which can lead to further degradation and breakage if not addressed. This makes the condition of being free from split ends a clear indicator of healthy hair, as it reflects the overall strength and vitality of the hair structure.
