Most Hair Supplements
Miss the Point.
TRX2® Doesn't.

Biotin and zinc support general hair health. But if your follicles are shrinking due to pattern hair loss, the real cause is a breakdown in potassium channel activity — something vitamins can't fix.

TRX2® is the first supplement formulated to restore potassium channel function — the molecular mechanism behind healthy follicle activity. Developed at the Oxford Science Park. Verified by independent clinical study.

The Science

Why Other Supplements Don't Work — And TRX2® Does

Most hair supplements throw a handful of vitamins at the problem and hope for the best. TRX2® was built differently — by starting with the actual chain of events that causes follicles to shrink, and designing a formula to push back against it, step by step.

What's Actually Shrinking Your Follicles

In follicles that are genetically sensitive, testosterone gets converted into a more potent hormone called DHT. Over time, DHT shortens each hair's growth phase a little more — so every cycle, the follicle produces a slightly thinner, shorter hair. Repeat this for a few years and thick hair gradually becomes the fine, "peach fuzz" hair typical of pattern hair loss.

How TRX2® Pushes Back

TRX2® combines L-Carnitine-L-Tartrate, Niacin, BCAAs and Potassium into a complex aimed at the follicle side of this tug-of-war. L-Carnitine has been shown to extend the hair's growth phase and increase the cells that build new hair. Niacin supports the potassium channels that keep follicle cells properly nourished, while the BCAAs help the follicle build those channels in the first place. Selenium and zinc round things out by protecting follicle cells from oxidative stress — another factor known to accelerate hair loss.

Why There Are No Side Effects

Hair-loss drugs work by forcing a change — blocking the enzyme that creates DHT, or forcing potassium channels open regardless of what the cell needs. That's effective, but it's also why they carry side effects: they override the body's normal regulation. TRX2®'s ingredients are nutrients your body uses every day anyway — just supplied in amounts tailored to support follicle health. Nothing is being overridden, which is why there's nothing to cause side effects.

Grounded in Peer-Reviewed Research TRX2®'s formula isn't a marketing story — it's built on published research. Studies have shown L-Carnitine-L-Tartrate extends the hair growth phase (Foitzik et al., 2007), and niacin supports the potassium channels implicated in pattern hair loss (Sukhodub et al., 2011). The complete formula was then clinically tested by Oxford Biolabs' own scientists (Bayer et al., 2019) — the same study behind the 87% improvement figure above.

Questions

Everything You Need to Know

You receive 3 bottles of TRX2® every 90 days, automatically. You're charged €168.95 (including VAT) per cycle with free shipping to EU and USA. You can pause, modify, or cancel your subscription at any time through your account — no penalties, no questions asked.
The hair growth cycle means results aren't overnight. First signs typically appear around months 3–5 for most customers, with cosmetically significant results at 8–10 months. A small number of customers see early changes at 12 weeks. The Supersaver is designed so you never miss a dose during this critical window.
TRX2® contains only drug-free, naturally-occurring compounds. The formula has no hormone interference and the dosage is well below experimental levels. Occasionally customers report mild, transient digestive effects — taking TRX2® with food eliminates this for most people. No major side effects have been reported in clinical studies.
Yes. TRX2® is effective for both men and women experiencing Androgenetic Alopecia (pattern hair loss). The formula works best for early-to-mid stage loss (Norwood stages 1–4 for men, Ludwig stages I–II for women), typically between ages 18–42, though many customers outside this range also report positive results.
Oxford Biolabs offers a 60-day money-back guarantee on all international orders. If you're not satisfied, return the product within 60 days for a full refund (excluding shipping and a €5.50 handling fee). Email support@oxfordbiolabs.com to initiate a return.
Because TRX2® works by maintaining the biological activity of your follicles, consistent supplementation is key. Most customers who discontinue use see their condition gradually return to its previous state over time — which is why uninterrupted delivery through the Supersaver is the most effective way to maintain results.
Yes — TRX2® is drug-free and works at the cellular level, so it does not interfere with minoxidil or post-transplant recovery. Many customers use TRX2® alongside topical treatments or as part of their post-transplant care to support follicle health in non-transplanted areas. As always, consult your physician if you have specific medical concerns.
