Diet and genetics play significant roles in influencing hair growth. Genetics determines the inherent characteristics of your hair, including its thickness, type, and growth rate. Some individuals may have a genetic predisposition for thicker or faster-growing hair, while others may experience slower growth or thinner strands.

Diet significantly impacts hair health and growth because hair follicles require essential nutrients, vitamins, and minerals to function optimally. Nutrients such as protein, iron, omega-3 fatty acids, and vitamins like biotin and vitamin D are crucial for healthy hair growth. A well-balanced diet that provides these elements can lead to stronger, more resilient hair and may promote faster growth.

Other factors such as environmental conditions can certainly have an effect on hair quality and health, but they do not have as direct an influence on the rate of hair growth as diet and genetics do. Hair styling frequency and hair length are more about the appearance and manipulation of hair rather than its biological growth process.
