How to Determine Hair Density
The density of your hair is simply how thin or thick it is. The number of hair follicles in a specific area of your hair, say a 1-inch area, determines your hair’s density.
The only way to truly determine density is to have someone literally examine a 1-inch square section of your scalp and count the number of hair follicles, or the number of hairs, in that 1- inch section. However, you can also do a simple hair density test with just two of your senses — vision and touch. The width of your part can also serve as some indication of your density.
