Bryan Johnson Tested Everything for Longevity—This Is the Only Hair Growth Solution That Passed His Standards

Advertorial

Bryan Johnson doesn’t mess around.

Not with his health.

Not with his diet.

And definitely not with his hair.

The man who spends $2 million a year tracking every marker of aging refused to waste time on treatments that only might work.

So when he noticed his hair starting to thin, he turned to the one thing he trusts most: testing.

That’s how he discovered Roots by Genetic Arts—the only hair growth solution that begins with your DNA and builds a formula around your exact biology.

And today, that same approach—peer-reviewed and officially biohacker-approved by Biohack Yourself Magazine, the world’s only peer-reviewed biohacking journal—is helping thousands of men and women reverse hair loss and restore confidence in just 3–6 months.

The Secret Behind Bryan Johnson’s Hair Growth Protocol—And the Painful Reality Millions Face

Bryan has been called “the most measured man in history.” Every decision he makes comes down to data.

So when he noticed thinning hair,

he didn’t gamble on drugstore foams or generic pills.

“It’s not about trying every product out there—it’s about finding the right one. With Roots by GA, I know my treatment is backed by research and tailored precisely for me.”

What Bryan discovered—and what thousands are now realizing—is that hair loss isn’t just about aging.

It’s about your DNA.

What Goes Into a Formula That Meets Bryan Johnson’s Standards?

Generic shampoos and foams throw the same ingredients at everyone. Roots by GA is different—we design a formula built for your exact DNA profile and prescribe only what’s likely to work best for you.

Here’s a closer look at some of the clinically validated ingredients our doctors use in custom formulas:

• Minoxidil – Stimulates follicles and increases blood flow to the scalp for stronger, thicker strands.
• Latanoprost – Extends the growth phase of your hair cycle, helping hair grow denser and darker.
• Finasteride – Lowers DHT (the hormone behind male pattern baldness), slowing loss and promoting regrowth.

The Choice Is Yours

When it comes to hair loss, there are really only two paths forward.

Option #1 is to close this page and keep relying on generic foams, random pills, or over-the-counter products that never fully deliver.

You can keep hoping things will improve on their own… even as your hairline slowly recedes and confidence slips away.

You can keep spending money on treatments not designed for your biology—and risk years of disappointment.

Or you can try Option #2.

You can follow Bryan Johnson’s lead and join thousands of men and women who’ve chosen a smarter path—personalized treatment matched to their DNA.

With the Precision Hair Growth Bundle, you’re not guessing. You’re using science to target the exact genetic causes of your hair loss—and finally seeing results in as little as 3–6 months.

If you’ve read this far, it’s not by accident.

It means you’re ready to take back control of your hair, your confidence, and your life—without the trial-and-error.

The clinical results speak for themselves. So do the transformations of real people who trusted Roots by GA when everything else failed.

So ask yourself…

Which path feels right?

“I knew my grandad was bald — didn’t expect I’d inherit it this early. Took a DNA test with Roots by Genetic Arts (super easy, by the way) and found out hair loss really does run in the family. Now I’m on a custom prescription treatment, and honestly… it’s working. What do you think?”

– Jeff, 33

The Precision Protocol Behind Bryan Johnson’s Hair Routine

What Bryan discovered wasn’t another complicated protocol.

It was simple—the Precision Hair Growth Bundle by Roots by GA, which includes:

• At-Home Hair Loss Genetic Test (DNA cheek swab + prepaid return label)
• Custom 45ml Topical Treatment (prescribed by a board-certified dermatologist based on your DNA results)

Here’s how it works:

1. At-home DNA Test + Questionnaire – Quick cheek swab at home, with a prepaid return label so sending it back to the lab is effortless.
2. Insights Delivered – Within 10 days of the lab receiving the sample, a detailed genetic report is generated—analyzing 50 genes linked directly to hair loss.
3. Dermatologist Prescription – A board-certified dermatologist reviews the genetic insights and prescribes a custom topical treatment designed to match the individual’s unique biology.
