What exactly is "healthy hair"?

Question

I hear this phrase on tv ads all the time. Is there such a thing as UNhealthy hair? Is there diseased hair?? (ew). What are the facts. Sounds just like a marketing gimmick to me.. Anyone know?

Answer 1

Unhealthy hair is dry, brittle, limp, and dull. Healthy hair is soft, shiny, and has volume.
