The claim
In an October 2024 post on the Blueprint site, Bryan Johnson wrote that he began losing hair and going gray in his late twenties, and that by 46 he had a full head of hair with roughly half of his gray gone. He describes himself as genetically predisposed to baldness.
That single sentence about gray has done enormous work. It is repeated across YouTube, Reddit and TikTok, usually detached from the rest of the article. So it is worth being precise about what he actually said, and what he didn't.
What he actually does
The protocol he describes has five parts:
- A custom prescription topical, 1 ml to the scalp each morning, followed by a silicone scalp scrubber for one to two minutes. The formulation is built from a genetic test that predicts response to individual ingredients. His own version contains minoxidil 7%, cetirizine 1%, latanoprost 0.004%, dutasteride 0.25%, melatonin 0.1%, caffeine 0.2%, tretinoin 0.0125%, plus vitamins D3 and E.
- Oral minoxidil, 3.75 mg daily, titrated up from 2.5 mg.
- A red light cap, six minutes a day.
- Nutrition — adequate protein, omega-3, biotin, vitamins C, D and E, iron and zinc.
- Starting early, which he stresses more than anything else in the piece.
He also reports two things that get quoted far less often. He tried the topical twice daily and had to stop, because his DHT fell to 5.8 ng/dL — low enough to risk side effects. And he did PRP and PRF injections diligently for twelve months and saw next to no benefit, describing the process as painful, expensive and time-consuming before abandoning it. He is upfront that he runs many interventions at once and that a reader doesn't need to. He closes by saying it's helpful to remain humble.
The part nobody mentions
Not one item in that protocol is a treatment for gray hair.
Minoxidil, dutasteride, latanoprost and red light therapy all target hair growth and follicle miniaturization. None of them has an established mechanism for restoring melanin to a follicle that has stopped producing it. The gray observation is a self-reported, unquantified side note from a man running dozens of simultaneous interventions with no control condition. There is no way to attribute it to anything specific — and to his credit, he doesn't try to.
So if you arrived here because a video told you Bryan Johnson reversed his gray and sells the thing that did it: he doesn't. The Blueprint hair range is a hair loss range.
The products, reviewed
Prices are from the Blueprint US store and include the rating and review count shown at the time of writing. Review counts across the hair range are low — 10 to 43 — which is thin evidence either way.
Peptide Shampoo
$59The best-rated item in the range and the cheapest entry point. Copper peptides have some supporting literature for scalp and follicle health, though the trials are small and mostly industry-run. A shampoo has a contact time measured in seconds, which limits what any active can plausibly do.
For gray: no evidence. Verdict: a $59 shampoo is a $59 shampoo. If you want to try one thing from the range, this is the lowest-risk way to do it, but don't expect it to move pigment.
Peptide Hair Serum
$119This is the over-the-counter product, and it is not the formulation Johnson describes using. His is a prescription compound containing dutasteride, latanoprost and tretinoin. The retail serum is peptide-based precisely because it has to be sold without a prescription.
For gray: no evidence. Verdict: if you're buying it because you read his article, you're buying the wrong thing. The article's active ingredients aren't in it.
302 Laser Cap
$999Low-level laser therapy has the strongest evidence base of anything in the range for androgenetic alopecia — several regulator-cleared devices exist and the effect, while modest, is real. The problem isn't the technology, it's the pricing. Comparable cleared laser caps sell for a fraction of this. It also carries the lowest rating in the range, from ten reviews.
For gray: no evidence. Verdict: if you want laser therapy, buy a cheaper cleared device and put the difference towards something useful.
Haircare Stack
$178Shampoo plus serum. Bought separately that's $59 + $119 = $178. The bundle is $178. The saving is exactly zero. It exists to raise average order value, not to save you money.
Verdict: no reason to buy the bundle over the individual items.
The supplements
$39–$49These are broad multi-ingredient formulations, promoted alongside the hair article on the basis that the nutrients in question support hair health. That's true as far as it goes — but nutrients only help if you're short of them. Correcting a genuine B12, ferritin or vitamin D deficiency can affect hair, including pigment in some cases. Topping up when you're already replete does nothing.
Verdict: a blood panel tells you whether you need any of this. Do that first.
Before you go looking for the formula
The topical Johnson uses cannot be bought off the shelf. Dutasteride, latanoprost and tretinoin are prescription-only in the US, and oral minoxidil for hair is an off-label prescription use. Anything sold to you online as "Bryan Johnson's formula" without a prescription either isn't that formula or isn't legal.
The legitimate route is a physician or dermatologist. Topical minoxidil 5% is the one part of the protocol available over the counter, and it is the budget option Johnson himself points people toward.
What we'd actually do about gray
Honestly: very little, because very little works. If gray has arrived unusually early, get blood work done — B12, ferritin, vitamin D, copper and thyroid function. Correcting a real deficiency is the only intervention with a plausible route to affecting pigment, and it's cheap. Stop smoking if you smoke; it's one of the few lifestyle factors that shows up consistently in the research.
Beyond that, the options are coloring it or wearing it. Anyone selling you a third option is ahead of the evidence.
