The Role of Genetics in Hair Loss: Understanding Androgenic Alopecia

The Role of Genetics in Hair Loss: Understanding Androgenic AlopeciaBy New Look Institute, San Jose, CA

Have you ever looked in the mirror and thought, “Why is my hair thinning like my dad’s?” Or maybe you’ve seen the same hairline shape in old family photos. If so, it might not be your imagination — it could be genetics.

Hair loss doesn’t just happen by chance. One of the most common causes is called Androgenic Alopecia, also known as hereditary hair loss or pattern baldness. And yes — it can affect both men and women.

Let’s break it down in a simple, easy-to-follow way so you can understand what’s happening and what you can do about it.

What Is Androgenic Alopecia?

Androgenic Alopecia is a fancy term for the kind of hair loss that runs in families. It’s caused by genes you inherit from your parents — and sometimes, grandparents.

Here’s what happens:

• A hormone in your body called DHT (dihydrotestosterone) affects your hair follicles.

• Over time, DHT shrinks these follicles.

• Hair gets thinner, weaker, and may stop growing altogether.

This type of hair loss is very common and often starts slowly. But it can get worse over time if left untreated.

Signs You Might Have Genetic Hair Loss

Wondering if your hair loss is from your family genes? Here are some signs to look for:

👨‍🦲 In Men:

• Hairline starts to recede (move back)

• Bald spot on the crown (top/back of head)

• Thinning hair on the top, while sides stay fuller

👩‍🦱 In Women:

• Hair starts to thin at the part line

• Scalp becomes more visible over time

• Overall thinning, but hairline stays the same

This kind of hair loss usually gets worse with age — but it doesn’t have to!

How Is It Diagnosed?

A trichologist or hair expert can help you figure out if your hair loss is genetic. Here’s what they might do:

• Ask about your family’s hair history

• Look closely at your scalp with a special magnifying tool

• Do a scalp and follicle health check

• Sometimes run blood tests to rule out other causes

Knowing the exact cause is the first step to finding the best treatment.

Treatment Options That Don’t Involve Surgery

While you can’t change your genes, you can slow down hair loss — and even regrow hair — with the right non-surgical treatments. Here’s what can help:

💡 Low-Level Laser Therapy (LLLT)

• Uses gentle red light to boost blood flow and wake up hair follicles

• Safe, pain-free, and works great over time

🧴 Topical Treatments

• Minoxidil (yes, the stuff in drugstores) helps many people grow new hair

• Other serums with natural ingredients like rosemary and caffeine can support scalp health

💆‍♀️ Scalp Treatments

• A healthy scalp is key to growing strong, healthy hair

• Scalp exfoliation, oxygen therapy, and customized care plans can make a big difference

🧬 Trichology-Based Care

• Trichologists use science to treat the scalp, reduce DHT, and support follicle health

• They create personalized plans based on your hair type and needs

👩‍🦳 Hair Replacement Systems

• For more advanced hair loss, these non-surgical systems blend perfectly with your real hair

• Comfortable, natural-looking, and totally customizable
