Understanding the latest research and development in the genetics of hair loss can help people decide if they may be susceptible to hereditary hair loss and how to best protect their hair health.

The most common form of genetic hair loss is androgenic alopecia, which is caused by a sensitivity to Dihydrotestosterone (DHT). DHT is produced when testosterone is converted into its metabolites. Inherited hair loss generally occurs on the top and front of the head in men, and generally on the top of the head in women.

Genetics of Hair Loss

While genetics can explain some instances of hair loss, it’s important to keep in mind that hair loss is a multi-factorial condition and there are other factors at play. These additional factors include poor nutrition, medications, health conditions, and even stress.

However, genes are known to play an important role and they can often be the main cause of hair loss, especially in men and women with a family history of androgenetic alopecia. The gene responsible for the condition is located on the X-chromosome. This gene is thought to be inherited from a person’s mother and can increase the risk of male pattern balding in their offspring.

Hair Health and Treatment Options

If you are experiencing hair loss, it’s important to look into the potential causes, including genetics. Knowing if hair loss is hereditary can help you determine the best course of action for yourself, and to protect the hair health of your family.

Treatment options such as prescription medications or surgery are available, but they should be discussed with a healthcare provider. Also, lifestyle changes such as stress management, healthy diet, and improving hair hygiene, can help improve the health of your hair and reduce the risk of additional hair loss.


Genetics may play a role in hair loss, but it is not the only factor. Hair loss can be prevented or reversed if addressed early, so it’s important to watch out for the early signs and to speak to your healthcare provider if you have concerns about your hair health.
