Bryan Johnson Hair Protocol: Peptide Shampoo, Serum, Laser Cap & Minoxidil
Bryan Johnson hair protocol guide covering Blueprint Peptide Shampoo, Peptide Hair Serum, the 302 Laser Cap, minoxidil, ingredients, and research.

This Bryan Johnson hair protocol keeps the order simple: clean the scalp, apply the peptide products, use light therapy consistently, and keep minoxidil as the medical hair-growth layer when it is appropriate for you.
The Blueprint product buttons use the recommendation link and may show $25 off at checkout when eligible. For the dedicated coupon page, see the Bryan Johnson discount code guide. For a broader evidence map, see best peptides for hair growth. For the shampoo-specific breakdown, see peptide shampoo.
Protocol Order
| Order | Step | Use |
|---|---|---|
| 1 | Peptide Shampoo | Use as the scalp prep/treatment step in the shower. Massage into the scalp, leave for about 2 minutes, then rinse. |
| 2 | Peptide Hair Serum | Apply to a dry scalp, focus on thinning areas, massage in, and let it dry before styling products. |
| 3 | 302 Laser Cap | Use on dry hair/scalp for 6 minutes daily. Blueprint's public protocol uses the cap after the serum. |
| 4 | Minoxidil | Use topical minoxidil according to the product label or prescription plan. Oral minoxidil is prescription/off-label for hair and needs clinician guidance. |

Step 3
Blueprint 302 Laser Cap
$25 offThis is the light-therapy layer. Blueprint describes the device as an FDA-cleared 302-laser-diode cap for androgenetic pattern hair loss, used for 6 minutes daily on dry hair and scalp.
View laser cap| Spec / feature | Role |
|---|---|
| 302 laser diodes | Full-scalp coverage for common pattern-loss zones such as hairline, crown, and part line. |
| 655 nm red laser light | Low-level laser therapy wavelength used for hair-growth device protocols. |
| 6 minutes daily | Short daily exposure target from Blueprint's instructions. |
| Dry scalp use | Keeps the laser session consistent and matches Blueprint's directions. |
| Device layer, not a topical | Works separately from shampoo, serum, and minoxidil; consistency is the main variable. |
Minoxidil Layer
Minoxidil is not a peptide product, but it belongs in the protocol because it has direct human evidence for androgenetic alopecia. Blueprint's public protocol mentions topical minoxidil and oral minoxidil, but those are different risk categories.
| Option | Role | Notes |
|---|---|---|
| Topical minoxidil | Evidence-backed hair-growth medication layer. | Use according to the label or a prescriber's instructions. Let it dry before layering other scalp products. |
| Prescription topical blends | Clinician-directed formulas may combine minoxidil with other actives. | Follow the exact dose and timing from the prescriber. |
| Oral minoxidil | Off-label systemic option for hair loss. | Requires clinician oversight because it can affect blood pressure, fluid retention, heart rate, and body-hair growth. |
Evidence Map
| Layer | Evidence | Read |
|---|---|---|
| Topical minoxidil | 5% minoxidil RCT and DailyMed labeling. | Most evidence-backed layer in the protocol. |
| Laser cap / LLLT | Meta-analysis of randomized trials. | Reasonable adjunct for androgenetic hair loss when used consistently. |
| Caffeine | Topical caffeine vs minoxidil study. | Good active logic, especially in leave-on formulas. |
| Adenosine | Adenosine vs minoxidil study, topical adenosine trial, and adenosine complex study. | One of the better-supported cosmetic actives in the formula. |
| Copper tripeptide / GHK-Cu | GHK review and GHK-Cu delivery paper. | Interesting repair-signaling ingredient; finished-product hair-growth proof is limited. |
| PDRN | PRP plus PDRN hair-loss study. | Mechanistically interesting, but most hair data is not simple leave-on cosmetic use. |
| Follistatin-style peptides | Activin/follistatin hair-follicle biology review. | Supports the rationale, not a finished-product outcome claim. |
Safety Rules
Patch test the shampoo and serum first. Stop if you get burning, rash, severe itching, or unusual shedding. Be careful with irritated, infected, painful, sunburned, or recently treated scalps.
See a dermatologist for sudden shedding, patchy hair loss, scalp pain, scarring, infection, or hair loss tied to a medication or medical condition. For oral minoxidil, prescription minoxidil blends, finasteride, or dutasteride, use clinician guidance.
FAQ
What is Bryan Johnson's hair protocol?
Bryan Johnson's public hair protocol combines scalp products, hair-growth medications, and device-based light therapy. This page focuses on the practical stack people usually mean when they search for the Bryan Johnson hair protocol: Blueprint Peptide Shampoo, Blueprint Peptide Hair Serum, the 302 Laser Cap, and minoxidil.
What products are in the Bryan Johnson hair protocol?
The core Blueprint hair products are Peptide Shampoo, Peptide Hair Serum, and the 302 Laser Cap. The broader protocol also references minoxidil as a hair-growth medication layer.
Does Bryan Johnson use minoxidil?
Bryan Johnson's public protocol references both topical minoxidil and oral minoxidil. Topical minoxidil is available over the counter in many markets. Oral minoxidil is prescription and off-label for hair loss, so it needs clinician guidance.
Does Blueprint Peptide Hair Serum replace minoxidil?
No. Blueprint's peptide shampoo and serum are cosmetic scalp products. They can fit next to minoxidil in a routine, but they should not be treated as direct replacements for proven hair-loss medications.
How often do you use the Blueprint 302 Laser Cap?
Blueprint's laser cap directions describe daily use on dry hair and scalp for 6 minutes. Consistency matters more than occasional long sessions.
Which matters more, the shampoo or the serum?
The serum is the stronger peptide step because it stays on the scalp. The shampoo can still be useful as scalp prep, but rinse-off products have less contact time.
Is there a Bryan Johnson discount code for the hair products?
The recommendation links may apply $25 off at checkout when eligible. The coupon-focused page is here: Bryan Johnson discount code.
