Question: 1 / 400

Which factor can affect hair growth?

Dietary supplements

Genetics

Genetics plays a crucial role in determining hair growth patterns, including hair density, texture, and the speed at which hair grows. Each individual inherits a unique set of genes from their parents that can dictate how their hair behaves. For instance, some people may have a genetic predisposition for thinning hair or baldness, while others may have a genetic advantage for thicker and faster-growing hair.

While dietary supplements, hair products, and water intake can influence hair health and appearance, it is genetics that fundamentally sets the baseline for an individual's hair growth characteristics. Understanding the genetic factors can provide insight into potential challenges or advantages a person may have regarding their hair.
