## 30 percent of men bald by 30
Early baldness affects a significant portion of men, yet scientists have struggled to pinpoint exactly why it happens to some guys and not others.
## Your mom's metabolic health matters
Researchers found that genes linked to PMOS (formerly PCOS) in women can be inherited by men, increasing their risk of early baldness and metabolic disease.
## PCOS renamed to PMOS
The condition was renamed from PCOS to PMOS to reflect that it's a whole-body syndrome, not just an ovarian disorder, helping doctors avoid missing cases in men.

## No easy way to diagnose it yet
There's no definitive blood test to diagnose PMOS in women or men, making it hard to know if early baldness signals a metabolic issue or just genetics.
## Early baldness as a warning sign
Unusually early or aggressive hair loss can be the body's check-engine light for metabolic or endocrine issues, especially if you have family history.

## Start treatment immediately
Dermatologists recommend starting finasteride (a DHT blocker) and minoxidil together early, plus lifestyle changes like managing weight, stress, and blood pressure.

## Talk to your doctor about family history
If your mother or sister has PMOS, discuss screening for metabolic abnormalities with your doctor, especially if you're experiencing early baldness or severe acne.
## Key takeaway

Early baldness may signal a metabolic or endocrine issue inherited from female relatives, and treating it early with medications like finasteride and minoxidil works best.
