The Science Behind Hair Loss: Biology and Genetics

Science Behind

and Health

It’s natural to experience some hair loss over the years as we age, but what causes hair loss in certain individuals? The science behind hair loss is complex and involves factors such as biology, genetics, and health. Hair loss is a common condition that affects both men and women and can lead to significant psychological distress. Understanding the science behind hair loss can help individuals identify potential causes and treatment options.

The Biology of Hair Loss

It’s important to understand the biology of hair loss to gain insight into the various causes. Hair follicles remain in a state of active growth for a period of two to six years. During this time, the follicles produce new hairs which replace older hairs that are shed. Over-activity of the hormones testosterone and dihydrotestosterone (DHT) may cause the follicles to shrink, resulting in hair thinning and even complete baldness.

The Genetics of Hair Loss

Genetics are also believed to play a role in hair loss, with researchers finding that certain genes are linked to a greater risk of developing androgenetic alopecia. Androgenetic alopecia is the most common type of hair loss and is believed to be hereditary. While genetics can predispose individuals to hair loss, there are also environmental factors at play which can contribute to the process.

It is important to talk with a doctor if you are experiencing hair loss to identify potential causes and treatment options.

Preventing Hair Loss
