Do you often ask yourself, "Will I go bald if my dad is bald?" If so, you're not alone. 

Many believe that baldness runs in the family, but the truth is a bit more complex. 

In this article, we'll dive into the genetics of baldness, clarify some common misconceptions, and help you understand what really determines if you'll follow in your father's footsteps hair-wise.

How does the balding gene work?

It's a myth that a single gene decides if you'll go bald. Instead, baldness results from a mix of genes plus factors like diet, age, and health. Scientists have identified 63 genes that influence androgenetic alopecia, the scientific term for common hair loss.

The main player here is the AR gene, or androgen receptor gene, which profoundly affects male hair loss

Although everyone carries this gene, variations make some people's hair follicles more sensitive to dihydrotestosterone (DHT)

DHT is a hormone that causes hair follicles to shrink, leading to hair loss if your receptors are particularly sensitive.

More AR gene activity can increase the number of receptors on your hair follicles, further heightening your risk of hair loss. So, while the AR gene doesn't guarantee baldness, its behavior in your body plays a crucial role.

Will I go bald if my dad is bald?

Research shows a strong correlation—over 81% of sons with bald dads experience hair loss. However, inheriting baldness isn't guaranteed just because your dad is bald; genetics are more complex than that.

While there's a significant chance you might see a similar pattern due to genetics, the key gene affecting baldness—the AR gene—is linked to the X chromosome, typically inherited from your mother. 

This contributes to the common belief that baldness can be traced back to your mother's side of the family.

However, it's crucial to remember that numerous other genes also play a role in baldness. These genes are located on your autosomes, the non-sex chromosomes you inherit from both parents. Any of these genes might affect your hair loss, not solely those from your dad.

So, while there's a notable link between having a bald father and becoming bald yourself, many factors and genes can influence this trait, reflecting the complex nature of genetics.

What causes baldness in men?

Male pattern baldness, or androgenetic alopecia, primarily results from genetic factors and hormonal changes. It typically manifests as a receding hairline and thinning hair on the crown of the head.

Hair grows from follicles under the skin, and baldness occurs when these follicles shrink, producing progressively finer hairs until they no longer grow hair. 

Although the follicles don't die and can potentially grow new hair, they commonly cease hair production due to hormonal influences.

What are the signs of male pattern baldness?

Male pattern baldness often starts with a receding hairline that forms a distinctive "M" shape at the front of the head. Here are key signs to watch for:

  • Gradual backward movement of the hairline.
  • Expansion of a thinning area on the vertex of the head.
  • Hair becomes finer and takes on a U-shaped pattern around the sides and back of the head.

Baldness in your maternal grandfather can suggest a higher risk of early-onset male pattern baldness—this means potentially starting to lose hair before the age of 40. However, this doesn't guarantee baldness.

The genetics of baldness are complex, involving not just one gene but many, including those on autosomes (non-sex chromosomes). 

While there's a greater phenotypic resemblance between males and their maternal grandfathers in cases of baldness, this relationship is still under investigation.

Ultimately, if male pattern baldness is common in your family, regardless of which side it comes from, there's a good chance you might experience it too. 

More research is needed to fully understand the diverse genetic contributions to baldness.

How does the baldness gene affect women?

While women are less likely than men to experience genetic hair loss, about 30% of women will face female pattern hair loss by age 70. Both men and women have the AR gene, which influences hair loss, but because women have two X chromosomes, they inherit the AR gene from both parents.

Interestingly, some women develop hair loss without high levels of androgens like DHT, suggesting other mechanisms at play.

Researchers have also linked the CYP19A1 gene, which governs the aromatase enzyme converting androgens to estrogens in hair follicles, to hair loss in women. 

This connection might explain why hair loss in women often accelerates after menopause, when estrogen levels drop, impacting hair growth.

Is balding from a dominant or recessive gene?

Balding's genetic basis was once thought to hinge on whether the AR gene was dominant or recessive. Early 20th-century research suggested that the AR gene is autosomal dominant in men and recessive in women, meaning men could express symptoms with just one copy of the gene, whereas women needed two.

While this theory holds some water today, the picture is more complex due to the multitude of genes involved in hair loss. 

Thus, whether a gene is dominant or recessive is just part of the story—multiple genetic factors contribute to baldness, complicating predictions based on single genes.

How to know if you have male pattern baldness genes

The most reliable method to determine susceptibility to male pattern baldness is to observe your hair over time. Early signs often include hair thinning at the temples and front of the head. Some men might notice hair loss at the crown, but this usually indicates more advanced baldness.

As male pattern baldness can begin as early as late adolescence, being aware of these changes is crucial for early identification. 

Unfortunately, without genetic testing or visible symptoms, predicting whether you will experience male pattern baldness is challenging.

How to treat male pattern baldness

Here are some effective ways to treat male pattern baldness:

1. Bio-Pilixin® Activation Serum

Hair growth serum

Bio-Pilixin® Activation Serum is a cutting-edge solution designed to help combat hair thinning and promote hair growth. 

Developed using advanced stem cell technology, this serum includes multiple plant growth factors that nourish hair follicles and encourage healthier hair.

2. Minoxidil

Minoxidil is one of the most well-known treatments for male pattern baldness and is available without a prescription. 

It works by widening blood vessels and opening potassium channels, which allows more oxygen, blood, and nutrients to the follicles. 

This can help to revive shrunken hair follicles, increase their size, and prolong the growth phase of hair.

3. Finasteride

Finasteride is a prescription medication that reduces the production of dihydrotestosterone (DHT), a hormone linked to hair loss. 

It’s particularly effective in slowing hair loss and promoting regrowth at the crown and in the middle of the scalp. Finasteride is typically taken as a pill once a day and is most effective in men under 60.

4. Microneedling

Microneedling involves using a roller or pen equipped with fine needles to create tiny punctures on the scalp. 

This procedure is believed to stimulate the skin’s healing response, boosting collagen production and encouraging the growth of new hair. 

It’s often used in conjunction with other treatments, such as topical minoxidil, to enhance absorption and effectiveness.

5. Platelet-rich plasma therapy

Platelet-rich plasma (PRP) therapy involves drawing a patient’s blood, processing it to enrich the plasma with platelets, and then injecting it into the scalp. 

Platelets are rich in growth factors that can promote hair growth by stimulating follicular cells. PRP is becoming a popular option due to its natural approach and promising results in hair regrowth.

6. Hair transplant

A hair transplant is a more permanent solution for hair loss. It involves taking hair from parts of the scalp that still have active growth and transplanting them to thinning or balding areas. 

This procedure can offer dramatic improvements in appearance and is a long-term investment in regaining fuller hair.

Conclusion

Understanding baldness involves more than just looking at your family tree; it's about genetics, lifestyle, and other health factors. 

While genes like the AR gene play significant roles, both your mom's and dad's genetics contribute to hair loss risks. 

In this article, we've explored how baldness occurs and highlighted effective treatments, including Bio-Pilixin® Activation Serum.
