What Really Causes Male Pattern Baldness? Genetics, Hormones & More
Quick Answer
- Male pattern baldness is primarily caused by genetics and the hormone DHT.
- DHT shrinks hair follicles over time, producing thinner hair until growth stops.
- Lifestyle factors like stress and poor nutrition can accelerate the process.
Think your dad's baldness is your destiny? Well, you're not totally wrong—but there's more to the story. Let's unpack what's really behind male pattern baldness.
The Main Culprits
1. Genetics (AR Gene)
The androgen receptor (AR) gene plays a crucial role. If you inherit a sensitive version of this gene, your hair follicles are more susceptible to DHT damage.
2. DHT (Dihydrotestosterone)
DHT is a hormone derived from testosterone. When it binds to hair follicles (especially those with sensitive AR genes), it causes them to shrink and produce thinner, shorter hairs until they eventually stop growing.
3. Aging
As men age, hair follicles naturally become more sensitive to DHT, and the hair growth cycle shortens.
4. Inflammation
Chronic scalp inflammation can damage hair follicles and accelerate hair loss.
5. Lifestyle Factors
While genetics and hormones are the primary drivers, lifestyle factors like stress, poor nutrition, smoking, and lack of sleep can accelerate the process.
Environmental Factors
Environmental stressors, pollution, and UV damage can also contribute to follicle damage and hair loss over time.
The Bottom Line
Male pattern baldness is primarily driven by genetics and hormones (specifically DHT). While you can't change your genes, you can address DHT with clinically proven treatments like finasteride and minoxidil.
