GLP-1 Hair Defense · Micro-Infusion System

The Micro-Infusion Hair Recovery System

★★★★★ 3,578 reviews

Most hair loss products were built for pattern baldness. Yours isn't that. GLP-1 shedding is telogen effluvium, metabolic not hormonal, and it hits your follicles four ways at once. This system delivers 26 actives at clinical concentrations through 24K gold micro-channels to the dermal layer, past the surface where every serum you've tried has stopped.

Built for GLP-1 hair loss. The metabolic kind, not pattern baldness
2 minutes, once a week. Not another daily step to keep up with
Helps visibly reduce shedding. Fewer hairs in the shower, on the brush, on your clothes
Works to restore density along the part line and crown, where GLP-1 hair loss shows first

      How does the micro-infusion stamp work?

      The 24K gold 0.5mm needles create micro-channels through the scalp barrier — the same barrier that blocks 98% of topical serums. You apply the serum first, then press the stamp across the scalp for 2-3 minutes. The channels remain open for up to 24 hours, drawing all 26 actives directly to the dermal papilla where hair growth begins.

      Is it painful or difficult to use at home?

      No. At 0.5mm, the needles work within the epidermis only — no bleeding, no scarring, no professional supervision required. Most users describe a mild tingling. The 24K gold needles resist bacterial adhesion and cause less irritation than steel alternatives. The full protocol takes 2-3 minutes, three times per week.

      Will this work for my hair loss specifically?

      It was designed for it. Most hair loss products target DHT-driven pattern baldness — a different condition. GLP-1 hair loss is telogen effluvium caused by metabolic stress and rapid weight loss. Every ingredient in this formula was selected to address that mechanism. If your hair loss started 3-6 months after beginning a GLP-1 medication, this system was built for your situation.

      What's included?

      The starter kit includes the micro-infusion stamp device (24K gold, 0.5mm needles), a one-month supply of the GLP-1 Hair Defense Serum (26 actives, full concentrations disclosed), and a protocol guide. The 3-month and 6-month kits include additional serum supply at a lower per-month cost, and include priority access to our customer care team.

      The Protocol

      Two minutes. Once a week.

      Every serum vial is one complete session. Apply, stamp, and continue your normal routine. The actives are now inside your follicles, not sitting on the surface where they can't reach.

      Part and apply
      1

      Part and apply

      Apply the full serum vial directly to your dry scalp. Start along your part line, then work across the crown. These are the two areas where GLP-1 telogen effluvium shows first, and where the formula needs to reach.

      Stamp
      2

      Stamp

      Press the 24K gold stamp firmly across the treated area in overlapping passes. The 0.5mm microneedles create micro-channels through the scalp barrier in seconds — the same mechanism that produced 4x results over topical application alone in the landmark Dhurat clinical trial. Two minutes covers your full part line and crown.

      Absorb
      3

      Absorb

      No rinse. No waiting period. The formula is now at the follicle level, not sitting on the surface of your scalp. Apply any remaining serum along your hairline. Continue your normal routine.

      Clinical note. Micro-channels remain open for absorption for up to 24 hours post-treatment, with peak uptake in the first 2 hours. Apply serum before stamping, not after.

      The research is published. Every claim has a citation.

      26 Ingredients. Nothing Hidden.

      GHK-Cu (Copper Tripeptide-1) 2%

      GHK-Cu (Copper Tripeptide-1)

      Modulates over 4,000 genes involved in follicle repair. Stimulates dermal papilla cells by up to 70% and rebuilds the damaged follicle microenvironment caused by metabolic stress.

      AnaGain (Pisum Sativum) 5%

      AnaGain (Pisum Sativum)

      Upregulates NOGGIN to push resting follicles back into growth. Downregulates DKK-1 — the molecular driver of telogen effluvium. Targets the exact mechanism GLP-1 hair loss disrupts.

      Capixyl 5%

      Capixyl

      Anchors hair by rebuilding the extracellular matrix around each follicle. Increased anagen/telogen ratio by 46% in clinical data. Efficacy comparable to 3% minoxidil with zero adverse reactions.

      Adenosine 0.75%

      Adenosine

      The cellular energy signal that wakes resting follicles. Extends the anagen growth phase and activates the Wnt/beta-catenin pathway. Approved for hair loss treatment in Japan.

      Procapil 1%

      Procapil

      Three-component complex that improves scalp blood flow, anchors hair in the follicle, and protects against follicle miniaturisation — without hormonal pathways or pharmaceutical side effects.

      Apple Stem Cells (PhytoCellTec) 0.5%

      Apple Stem Cells (PhytoCellTec)

      Protects follicle stem cells from the exhaustion caused by rapid, repeated telogen cycling during GLP-1 weight loss. The cells responsible for initiating every new growth cycle.

      Procyanidin B2 1%

      Procyanidin B2

      An apple polyphenol that unblocks the PKC enzyme and promotes hair cell proliferation. In the first clinical trial, efficacy was comparable to minoxidil and finasteride with no side effects.

      Caffeine 0.5%

      Caffeine

      Counteracts testosterone-induced hair growth suppression at the follicle level. Female follicles show higher sensitivity to caffeine than male making it disproportionately effective for our ICP.

      Niacinamide 3%

      Niacinamide

      Reduces inflammatory cytokines elevated during rapid weight loss. Strengthens the scalp barrier and downregulates DKK-1 expression — improving follicle health from the outside in.

      Vitamin C (L-Ascorbic Acid) 2%

      Vitamin C (L-Ascorbic Acid)

      Neutralises free radicals generated by rapid metabolic change. Essential cofactor for collagen synthesis in the follicle dermis. Stabilised with Ferulic Acid for sustained delivery.

      Ferulic Acid 0.5%

      Ferulic Acid

      Doubles the antioxidant efficacy of Vitamin C by stabilising the molecule and extending its protective window. The exact 0.5% from the Pinnell landmark study — evidence-based, not estimated.

      Resveratrol 0.5%

      Resveratrol

      Acts as a caloric restriction mimetic — creating conditions favourable to follicle survival during GLP-1 caloric restriction. In a 12-week trial, reduced hair shedding by 61.47%.

      Taurine 0.5%

      Taurine

      Protects against TGF-beta1 — the master switch of follicle miniaturisation. Taken up directly by the hair bulb and outer root sheath, acting as an anti-fibrotic shield around each follicle.

      Rosemary Extract Standardised

      Rosemary Extract

      Performed comparably to 2% minoxidil at 6 months in a randomised trial — with no scalp itching or dryness. Improves perifollicular microcirculation and mildly inhibits 5-alpha reductase.

      Panax Ginseng Extract Standardised

      Panax Ginseng Extract

      Ginsenoside Rg3 promotes VEGF expression, improving vascular supply to starved follicles. Suppresses BMP4 which inhibits follicle development. Clinical evidence in alopecia areata.

      Green Tea Extract (EGCG) Standardised

      Green Tea Extract (EGCG)

      Nearly doubled hair follicle length in organ culture studies. Inhibits the androgen receptor at the follicle level and protects follicle cells against oxidative stress from rapid weight loss.

      Got questions

      Everything you need to know before you start

      The Genology system is formulated specifically for telogen effluvium triggered by rapid weight loss on GLP-1 medications — Ozempic, Wegovy, Mounjaro, and Zepbound. If your hair loss started 3-6 months after beginning a GLP-1 medication, this is the right product. If you have androgenetic alopecia (hormonal pattern baldness), this system is not designed for that condition.

      Yes. The 0.5mm needle depth is classified as a cosmetic procedure, not a medical one — it works within the epidermis and upper dermis only. At this depth, there is no bleeding, no scarring, and no professional supervision required. The 24K gold needles reduce irritation and resist bacterial adhesion compared to steel alternatives.

      Most users notice reduced shedding within weeks 2-4 — the first sign the telogen effluvium cycle is being disrupted. Visible new growth typically appears at months 2-3. Meaningful density improvement at months 3-4. Hair didn't thin overnight and it won't recover overnight — which is why our guarantee covers 120 days, not 30.

      No. Genology is applied topically to the scalp — it does not enter systemic circulation and has no interaction pathway with GLP-1 receptor agonists. This is fundamentally different from oral supplements like Nutrafol that enter the bloodstream. As always, consult your prescribing physician if you have concerns.

      Because Nutrafol and most hair supplements target hormonal pattern baldness — a different condition caused by DHT. GLP-1 hair loss is metabolic telogen effluvium. No amount of biotin or saw palmetto addresses the actual cause: metabolic stress, nutritional depletion, oxidative damage, and follicle stem cell exhaustion from rapid weight loss.

      0.5mm is shallower than a mosquito bite. The 24K gold needles reduce irritation compared to steel. Most users report a mild tingling sensation, not pain. The two-minute session is less time than she spends dreading the shower drain.

      Try the system for a full hair growth cycle. If you do not see results, contact us for a full refund — no questions, no photographs required, no hoops. We set the guarantee at 120 days because that is what the biology demands. A 30-day guarantee on a hair recovery product is not a guarantee at all.

      Yes — and this is when it matters most. The Genology system is designed to be used alongside your medication, not after you stop. The hair loss occurs because of the rapid metabolic changes your medication causes. Addressing those changes while you're still on treatment gives your follicles the best chance of recovery without interrupting your weight loss progress.

      A regular topical serum delivers approximately 2% of its actives to the follicle — the stratum corneum blocks the rest. The Genology micro-infusion stamp creates direct channels through the scalp barrier, increasing active delivery by up to 300%. The same ingredients in a regular serum produce dramatically different results when delivered past the barrier versus sitting on top of it.

      Rinse the stamp head under warm running water immediately after each use, then spray with 70% isopropyl alcohol and allow to air dry completely before storing. Replace the needle head every 8-12 uses or if you notice any bending or dulling of the needles. Replacement heads are available separately.
