Glossary Capillary Density

number of tiny blood vessels per unit area of tissue

Capillary density refers to the number of capillaries (tiny blood vessels) per unit area of tissue. In the context of hair and scalp health, higher capillary density can indicate better blood flow and nutrient delivery to hair follicles, which is crucial for hair growth and overall scalp health. This term is also used in other biological contexts, such as muscle tissue, where it can affect oxygen delivery and metabolic efficiency.
