If you're noticing gradual hair thinning or pattern hair loss, you may wonder: Is it just age, or is it in my genes? The answer, in many cases, is both. Androgenic Alopecia (AGA)—commonly referred to as male- or female-pattern baldness—is primarily a genetic condition.
What Causes AGA?
AGA is linked to a hormone called DHT (dihydrotestosterone), which is derived from testosterone. In people who are genetically predisposed, DHT causes hair follicles to shrink over time. This leads to thinner, shorter hair and eventually to permanent hair loss in certain areas of the scalp.
Is Hair Loss Inherited?
Yes. Genetics play a major role in AGA. The condition often runs in families, and both men and women can inherit the genes that make their hair follicles sensitive to DHT.
There’s a common myth that baldness only comes from the mother’s side, but this is not entirely accurate. While one of the key genes related to hair loss is found on the X chromosome (which men inherit from their mothers), many other genes from both parents can influence hair density, thickness, and DHT sensitivity.
How to Tell if You're at Risk
If you have close family members—like a father, mother, uncle, or older sibling—who have experienced pattern hair loss, your likelihood of developing AGA is higher. The following may increase your risk:
-
A family history of early-onset balding (before age 30)
-
Thinning around the crown or temples (in men)
-
A widening hair part or overall thinning (in women)
However, the pattern and timing of hair loss can vary even among relatives with the same condition.
What You Can Do If You Have a Family History
While you can't change your genetics, you can take steps to delay or minimize the impact of AGA:
-
Catch it early
If you're noticing early signs like increased hair shedding or a receding hairline, consult a dermatologist or trichologist. Early treatment can slow the progression. -
Adopt a hair-friendly lifestyle
Eating a balanced diet rich in zinc, iron, biotin, and vitamins A, D, and E can support healthy hair. Managing stress and avoiding harsh hair treatments also helps. -
Consider supplements
Nutritional supplements—especially those containing zinc, saw palmetto, and vitamin D—may support scalp health and hair strength. While they won’t reverse genetics, they can improve overall hair condition. -
Use proven treatments
FDA-approved treatments like minoxidil (a topical solution) can help stimulate hair growth and slow thinning, especially when started early. -
Seek expert advice
A medical professional can help you determine whether your hair loss is due to AGA or another cause, and suggest tailored treatments or lab tests if needed.
Final Thoughts
AGA is indeed genetic, but that doesn't mean hair loss is inevitable or irreversible. Understanding your family history allows you to act early and take proactive steps. A combination of proper care, nutritional support, and expert guidance can go a long way in managing hair loss effectively
