Androgenetic Alopecia: Connection between Genetics, Testosterone, and Age

15 Mar, 2023

Androgenetic alopecia, commonly known as Male Pattern Baldness, is a common type of hair loss that affects millions of people all over the world. This condition is caused by a combination of several factors, including genetics, testosterone, and age. In this blog, we’ll explore the connection between these three influential factors and how they contribute to Androgenetic Alopecia.

Genetics and Androgenetic Alopecia

Genetics play a significant role in Androgenetic Alopecia. The condition is often passed down from one generation to the next and is believed to be caused by several genetic factors. If your parents or grandparents experienced hair loss, there’s a good chance you will too. However, genetics is just one factor in the development of androgenetic alopecia, and other factors, such as testosterone and age, also play a role.

Testosterone and Androgenetic Alopecia

Testosterone is a male sex hormone that plays a crucial role in the development of male characteristics, such as muscle mass, body hair, and a deep voice. However, testosterone can also have negative effects on the hair follicles, leading to hair loss.
Testosterone is converted into dihydrotestosterone (DHT) in the body, and it is this hormone that is responsible for shrinking the hair follicles and causing hair loss. High levels of DHT can lead to Androgenetic Alopecia, particularly in individuals who are genetically predisposed to the condition.

Age and Androgenetic Alopecia

Age is another factor that contributes to Androgenetic Alopecia. The condition begins in men at a predetermined biological age (genetic programming), with 30% of men starting in their late teens or twenties, 40% in their early thirties and so on. As the hair follicles shrink, hair becomes finer and eventually stops growing altogether.

It is impossible to prevent a genetic tendency, with poor lifestyle and diet you can prematurely aggregate your hair loss, starting the whole process a lot earlier and quicker. Or with a healthy diet and exercise we can help slow the rate of thinning as well.

Treatment Options for Androgenetic Alopecia

If you’re experiencing hair loss due to androgenetic alopecia, there are several treatment options available. Here are some options to consider:

1. Medications: Finasteride and Minoxidil are two commonly prescribed medications that can help to slow down hair loss caused by testosterone. Finasteride works by blocking the conversion of testosterone into DHT, while Minoxidil promotes hair growth by increasing blood flow to the hair follicles.

2. Lifestyle Changes: Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can help to reduce the negative effects of testosterone on the hair follicles.

3. Hair Transplantation: For those with significant hair loss, Hair Transplantation can provide a permanent solution. This procedure involves transplanting hair follicles from the back of the head to the front, where hair loss is more prevalent.


Androgenetic alopecia is a complex condition caused by a combination of several factors, including genetics, testosterone, and age. Understanding the connection between these factors can help you take steps to mitigate their effects and maintain a full head of hair. If you’re experiencing hair loss, consider speaking with a hair Trichologist to determine the best course of action for you.
