You were told hair loss is just genetics.

But over 1 of 3 men in their 20s are already thinning—and it’s getting worse every year.

This is a metabolic red alert.

Here’s what’s really driving early hair loss (and how to reverse it): 🧵

Hair loss used to hit men in their 40s and 50s.

Now? It’s hitting guys fresh out of college.

And the bald truth: it’s not just genes.

It’s your metabolism, your hormones, and the silent damage of modern life.

Watch to see the real truth behind your hair loss:

Let’s talk DHT.

Dihydrotestosterone is a testosterone byproduct that shrinks hair follicles.

But here’s the kicker—lifestyle factors like insulin resistance and stress amplify DHT activity.

It’s not just genetics. It’s the fuel we’re giving it, see yourself here:

Chronic stress = high cortisol.

Cortisol lowers testosterone and increases the conversion to DHT.

This means every sleepless night, every over-caffeinated, anxious day...
Is accelerating your hair loss.

And Gen Z is the most anxious, overworked, and underslept generation ever.

Then there’s insulin resistance.

Yes—pre-diabetes is linked to baldness.

Studies show men with higher insulin levels have more DHT activity in scalp tissue.

Sugar doesn’t just give you a gut—it can kill your hairline too.

Micronutrient depletion is another silent trigger.

Zinc, magnesium, biotin, and vitamin D are all essential for hair growth.

Most young adults are deficient in at least 2 of these.

Here are 4 things you should change immediately: 👇

1. Eliminate seed oils, sugar, and processed junk.

Seed oils (like canola, soybean, sunflower) are loaded with omega-6 fats.

These trigger chronic inflammation and oxidative stress in hair follicles—leading to early miniaturization.

See what oil you should consume instead:

2. Fix sleep, lift heavy, manage stress.

Poor sleep and chronic stress spike cortisol—reducing testosterone and increasing DHT conversion.

Lift 3–4x/week, meditate daily, and aim for 7–9 hours of deep, uninterrupted sleep to restore balance.

3. Get your bloodwork done.

Hair loss is often a sign of hidden deficiencies or metabolic issues.

Check:
• Vitamin D
• Ferritin (iron storage)
• Thyroid (TSH, T3, T4)
• Fasting insulin

Optimizing these can restart growth, even if genetics aren’t in your favor.

4. Eat more protein.

Hair is made of keratin, a protein.

If you’re under-eating, especially while lifting, your body prioritizes muscles over hair.

And remember: hair growth is not essential, so your body sacrifices it first.

Hair loss is reversible if you catch it early.

But ignore it too long, and those follicles die for good.

This isn’t just about vanity.

It’s a metabolic signal that your body is under attack.

Your hair is trying to warn you.

If you’re under 30 and seeing hair fall:

Don’t panic, act.

You can fix this with the right inputs, not just pharmaceuticals.

Optimize your body, and your hair often follows.
