The hair's natural color is primarily determined by what?

External products
Genetics
Health condition
Diet

The correct answer is: Genetics

The natural color of hair is primarily determined by genetics. Genetic factors influence the amount and type of melanin produced in hair follicles, which in turn dictates whether hair is blonde, brown, black, or red. Melanin comes in two forms: eumelanin and pheomelanin. The ratio and density of these pigments, determined by an individual's genetic makeup, establish a person’s hair color. While external products, health conditions, and diet can affect the appearance of hair or its health, they do not fundamentally change an individual's natural hair color, which is intrinsically tied to their genetic inheritance. Therefore, understanding the role of genetics in determining hair color is essential for anyone in the barbering or cosmetology fields, enabling them to provide accurate advice to clients regarding hair coloring and care.
