Do You Inherit Hair Loss from Your Mom or Dad?

Hair loss can be a sensitive topic, and understanding its genetic origins can help clear up some common misconceptions. Many people believe that hair loss is only inherited from their mother’s side of the family—specifically from their maternal grandfather. But is this really true?

The Genetics of Hair Loss

Hair loss, especially male and female pattern baldness (androgenetic alopecia), is influenced by multiple genes, which come from both parents. The gene most commonly linked to baldness, AR (androgen receptor), is located on the X chromosome, which males inherit from their mothers. This connection explains the origin of the “mom’s side” myth; however, it doesn’t tell the full story.

Your Mom’s Side – The X Chromosome Link

Since males inherit the X chromosome from their mothers, any hair-loss-related genes on that chromosome are more likely to impact male offspring. But females, who inherit an X chromosome from each parent, can also inherit these genes and may experience hair thinning or loss, though often to a lesser degree.

Your Dad’s Side – It Matters Too

It’s important to remember that there are other genetic factors outside the X chromosome, many of which can come from the father’s side. For instance, multiple genes located on non-sex chromosomes, known as autosomes, also play a role in hair loss. Therefore, both maternal and paternal genes can contribute to the likelihood and pattern of hair loss.

How Hereditary Factors Work Together

Hair loss is polygenic, meaning that it results from multiple genes interacting, often across both sides of the family. So, while you may inherit a key gene for hair loss from your mother, contributions from your father’s side might influence how early or severe the hair loss will be.

Busting the Myth

Ultimately, hair loss isn’t as simple as inheriting it from one side of the family. Instead, it’s a blend of genetic influences that come from both parents. If you have a family history of hair loss on either side, it may increase your likelihood of experiencing it yourself, but it’s not a guarantee.

Considering Treatment

If you’re noticing hair loss and are concerned about genetic factors, speaking with a hair restoration specialist can provide clarity. A professional can help you understand your unique situation and guide you on options ranging from medical treatments to hair transplant solutions.
