The GHK-Cu Micro-Infusion System combines a 0.5mm microneedle stamp with a dual-peptide serum chamber. The stamp creates hundreds of micro-channels across the scalp, allowing GHK-Cu, Rosemary Extract, and Caffeine to absorb deeper than topical solutions alone. Three times a week. No grease, no twice-daily routine.

Yes. The 0.5mm needles are ultra-fine and designed to reach just the upper layer of the scalp — enough to enhance absorption, but not deep enough to cause pain, bleeding, or irritation. Mild tingling is normal and a sign the serum is being absorbed.

Minoxidil requires twice-daily application indefinitely — stop using it and hair loss can return worse than before. Finasteride interferes with your hormones and carries documented side effects many men aren't willing to risk. This system is drug-free, hormone-free, and carries no rebound risk if you stop.

1 Month Supply: 1x micro-infusion stamp + 3x 5ml serum vials — 3 full treatments.

2 Month Supply: 2x micro-infusion stamps + 6x 5ml serum vials — 6 full treatments.

3 Month Supply: 3x micro-infusion stamps + 9x 5ml serum vials — 9 full treatments.

GHK-Cu (Copper Tripeptide-1) — supports healthier-looking follicles and scalp environment.

Acetyl Tetrapeptide-3 — helps support the appearance of fuller, denser-looking hair.

Rosemary Leaf Extract — studied ingredient, compared directly to minoxidil 2% in a 2015 Skinmed Journal trial.

Caffeine — supports a follicle-friendly scalp environment.

Biotin, Vitamin C, Vitamin E, Hyaluronic Acid — scalp conditioning and antioxidant support.

Here’s how it works:

  • You've Tried Things, But Nothing's Quite Stuck

    The crown, the hairline, the temples. You've noticed it for a while now. Maybe you tried minoxidil — the grease, the itch, the twice-a-day commitment. Maybe a serum that smelled expensive and did nothing. Not because you gave up. Because nothing you tried was actually getting through.

  • It Took a While, But You Finally Found It

    The micro-infusion stamp delivers the serum directly into the scalp — GHK-Cu, Rosemary, and Caffeine where they can actually do something. Three times a week, alternate days. No greasy residue. No complicated routine. Just stamp, absorb, and get on with your day.

  • Slowly, Looking at the Mirror Gets Easier

    Then one day your missus asks if you've had a haircut. You haven't told her anything. Then a mate says your hair's looking different. Then you notice it yourself — the crown, the temples, looking fuller than they did a few months back. No dramatic reveal. Just quietly, things looking better.

    Less in the drain. That's all I needed

    Three weeks in and I noticed less hair coming out in the shower. That was enough for me to keep going. Now at month four and the crown's visibly fuller — my barber actually commented without me saying anything. Didn't expect it to work this fast.

    Tried minoxidil for two years. This is different.

    Minoxidil made my scalp itch constantly and when I stopped it came back worse than before. Switched to this because there's no rebound risk and no greasy residue. Eight weeks in and shedding has slowed right down. Something is actually happening up there. Minoxidil made my scalp itch constantly and when I stopped it came back worse than before.

    My wife noticed before I did.

    I hadn't told her I was trying anything — just quietly did it three times a week and waited. Around week seven she asked if I'd had a haircut because it looked thicker. That was all the confirmation I needed. Still going and it keeps improving. I hadn't told her I was trying anything — just quietly did it three times a week and waited.

    Sceptical bloke, converted.

    Genuinely bought this thinking it probably wouldn't do much. I've been burned by enough ads to know better. But two months in the temples are filling in and I've got baby hairs at the hairline I haven't seen in years. Proper surprised. Genuinely bought this thinking it probably wouldn't do much.

    No side effects. That was the whole point.

    I refused to touch finasteride after reading about what it does. This has none of that — no hormones, no pills, nothing my body has to fight. Scalp feels good after every use and the shedding has slowed noticeably. Finally something I can actually stick with. I refused to touch finasteride after reading about what it does.

    Good product, just takes patience.

    Results took longer than I hoped — about ten weeks before I saw anything real. But I'm seeing new growth at the temples now and the crown looks stronger than it did six months ago. Shipping took a bit longer than expected too. Sticking with it though — it's working. Results took longer than I hoped — about ten weeks before I saw anything real.

    The 4 Science-Backed Principles of How the GHK-Cu Micro-Infusion System Works

    1. Micro-Infusion Activation

    At the core of the system is the 0.5mm gold-plated microneedle stamp, designed to gently create hundreds of tiny, painless micro-channels across the scalp. These channels support better serum absorption, allowing GHK-Cu, Rosemary Extract, and Caffeine to reach deeper than standard topical application alone. Three times a week. No grease, no harsh chemicals, no daily commitment.

    A 2022 systematic review and meta-analysis by Gupta et al. (Journal of Cosmetic Dermatology) found that microneedling monotherapy significantly increased total hair count — outperforming topical minoxidil 5% in the same study. Microneedling works by supporting the scalp's natural renewal process, improving circulation and enhancing delivery of active ingredients to the scalp environment.

    2. The Dual-Peptide Formula

    GHK-Cu & Acetyl Tetrapeptide-3

    The serum is formulated with two of the most researched actives in hair science — GHK-Cu (Copper Tripeptide-1) at 0.3% and Acetyl Tetrapeptide-3 at 5%. Together they support a healthier-looking scalp environment, helping to maintain the appearance of fuller, denser hair with consistent use.

    A 2023 study by Gelfuso et al. demonstrated significantly improved scalp delivery of GHK-Cu using a microemulsion system, supporting better absorption of the peptide into the scalp. A 2016 clinical trial by Lee et al. found that a GHK peptide complex showed improvement in male pattern hair loss participants.

    Study 2: Lee et al., 2016

    Link: https://pubmed.ncbi.nlm.nih.gov/27479396/

    3. DHT-Balancing Botanical Support

    As you age, DHT levels can increase — contributing to the appearance of thinning hair over time. The GHK-Cu Micro-Infusion serum contains Rosemary Leaf Extract, Caffeine, and Licorice Root Extract — botanicals studied for their role in supporting a healthier scalp environment and helping to counter DHT-related stress on the follicle.

    A 2024 study by Hagiwara et al. found that 18-β-Glycyrrhetinic Acid (from Licorice Root) inhibited 5α-reductase activity and supported dermal papilla cell proliferation in laboratory studies. A 2007 in-vitro study by Fischer et al. found caffeine counteracted testosterone-induced suppression of hair follicle growth in human follicle organ cultures.

    4. Scalp Health

    The Foundation of Fuller-Looking Hair

    A healthy scalp is essential for hair that looks and feels its best. The serum is formulated with Panthenol (Pro-Vitamin B5), Niacinamide, and Green Tea Extract — ingredients studied for their role in hydrating and conditioning the scalp, strengthening the scalp barrier, and protecting against environmental oxidative stress.

    A human clinical trial by Draelos et al. (Cutis, 2005) found that Niacinamide significantly improved skin barrier function and hydration, reducing transepidermal water loss and skin irritation — supporting a healthier, follicle-friendly scalp environment. A 2025 mechanistic study by Marsh et al. found that Panthenol penetrates the hair shaft and forms hydrogen bonds with hair proteins, increasing tensile strength and elasticity — helping reduce breakage and structural stress on hair.

    How long until I see results?

    Hair wellness takes time and varies person to person. Most people notice their hair feeling stronger and looking healthier before they see visible changes. Be consistent, give it a full routine cycle, and let the ingredients do their job. Don't judge it in two weeks.

    A regular serum sits on the scalp surface. The micro-infusion stamp helps the serum absorb more effectively and deeply into the scalp — getting the GHK-Cu, Rosemary, and Caffeine where they can actually do something rather than evaporating on top.

    Many people switch to this after minoxidil because it's drug-free, hormone-free, and doesn't come with dependency concerns. There's no rebound risk if you stop. If you're currently on minoxidil we'd recommend speaking to your GP before making any changes to your routine.

    Yes. The formula is drug-free and hormone-free with no synthetic dyes or harsh preservatives. The essential oils — Tea Tree, Peppermint, Eucalyptus — provide a mild cooling sensation most people find pleasant. If you have an active scalp condition like psoriasis or dermatitis, check with your GP before starting.
