Acquired canities is primarily the result of which factor?

Stress
Genetics
Age
Nutrition

The correct answer is: Age

Acquired canities, commonly referred to as premature graying of hair, is primarily attributed to the aging process. As individuals age, the pigment-producing cells in hair follicles (melanocytes) gradually decrease in activity, leading to a reduction in melanin production. This results in hair gradually losing its color and turning gray or white. While various factors can contribute to the onset of canities, such as stress or nutritional deficiencies, these often play a secondary role compared to the natural aging process. Aging is a biological inevitability that affects everyone, although the exact timing may vary between individuals based on genetics and environmental influences. Therefore, recognizing age as the main factor governing acquired canities is crucial in understanding the phenomenon of graying hair.
