How Bryan uses it:

Protocol 1: Blueprint Peptide Shampoo in shower

Protocol 2: Blueprint Peptide Serum post shower

Protocol 3: Blueprint 302 Laser Cap for 6 minutes to regrow hair

What if I use Minoxidil / Finasteride?

Blueprint hair care products are not a replacement for Minoxidil. Minoxidil is designed to slow hair loss. Blueprint Peptide Shampoo and Peptide Serum uses a nanoliposome system to deliver peptides to the scalp for follicle vitality. 

You can use all three as part of your protocol.

Suggestions if you are using Minoxidil / Finasteride:

Morning

+ Use Blueprint Peptide Shampoo

+ Apply Minoxidil / Finasteride in the morning on a clean, dry scalp

Night

+ Apply Blueprint Peptide Serum

+ Wear the Blueprint 302 Laser Cap for 6 minutes

Frequently asked questions


Micro needling can be used alongside Blueprint Peptide Serum and Blueprint Peptide Treatment Shampoo which can enhance product penetration. If you micro needle, do it and then apply the Blueprint Peptide Serum. Not the other way around. And not too much.

No. The Blueprint formulations are for scalp and follicle vitality. Minoxidil is designed to slow hair loss.  You can use Minoxidil, Blueprint Peptide Treatment Shampoo, and Blueprint Peptide Serum as part of your hair protocol. See instructions above.

Changes to scalp and hair health take at least 4 months. The key is to be consistent over the four month time period. Results will be motivating to continue usage.

Yes, Blueprint Essential Capsules, Advanced Antioxidants, and Collagen Peptides. Essential Capsules have antioxidants such as Vitamin C and zinc. Advanced Antioxidants has fat-soluble antioxidants including Lutein, Zeaxanthin, Lycopene and Vitamin K1 and K2. Collagen supports hair and skin by providing structural proteins that maintain skin firmness and elasticity while strengthening hair follicles for healthier growth. I consume Blueprint Collagen daily which has type I, II & III.

No. Blueprint formulations are designed to support scalp and follicle vitality. Finasteride and dutasteride are prescription DHT blockers that primarily prevent further loss rather than directly stimulating new growth, though some individuals may experience modest regrowth as a secondary benefit.

The Blueprint formulations can be used to support scalp and hair health at any stage. 

Some users report differences in the appearance of gray hair, but more research is needed.

    Great Stuff!

    It is not greasy, and spreads well. I believe it's already working, I am seeing small new growth. It's nice that it is unscented, great product!

    Blown Away!!

    I’m 40 years old- and I have tried all the “nice” products. Nothing beats this serum, and the companion shampoo. Thank you Bryan Johnson for putting this product out there. I’ve always felt like hair products have stripped away instead of replenish. This one replenishes and revitalizes. I can’t recommend it enough! Buy it. Try it. It’s worth it.

    Wow! Powerful stuff…. A little scary tho

    I have noticed hair regrowth within 3 weeks. Very very powerful serum. While it is working for hair regrowth, especially since I am combining with a red light cap - I feel like the peptides are going systemic. All of the peptides in this product are growth promoting… leading me to be weary of potential tumor growth. Experiment peptides without much safety data published. It also seems to cross my blood brain barrier and makes me feel more angry than usual and emotionally less regulated… very strong stuff but I do think the nanoencapsulation of the peptides is leading to systemic effects that might effect the cell cycle and promote potential metastatic and cell cycle disregulation in favor of growth… this is my 2 cents. Use product with caution. A little goes a long way.

    We’re glad to hear you’ve noticed visible results with the Peptide Serum. We want to reassure you that all Blueprint products are tested for quality and safety before release and are designed to only benefit hair and scalp health.

    The formulation uses biomimetic peptides that replicate naturally occurring signaling compounds in the skin and scalp, and they are not designed to act systemically or cross the blood-brain barrier. Each ingredient is carefully evaluated for topical use, and the product was developed to support rejuvenation at the scalp level only.

    We always recommend patch testing and using the serum as directed, as a little truly does go a long way. Thanks for sharing!
