Locerin Review 2026Does It Actually Work?

What is in it, per 2 capsules: 16 ingredients, led by AnaGain Nu (a pea sprout extract) 100 mg, with horsetail and bamboo silica, nettle leaf, MSM, alfalfa, cayenne, biotin 500 µg, zinc 10 mg, copper, manganese, selenium, magnesium, niacin and vitamin C.

What the evidence says:

• AnaGain Nu is at the studied dose, but the evidence is thin: one supplier study of 21 people over 8 weeks, with no placebo group mentioned.
• Biotin has no evidence of helping hair in people who are not deficient, and can distort some blood tests.
• A 2023 JAMA Dermatology review of hair supplements lists zinc among those with potential benefit; none of Locerin's other ingredients appear on its list.

The page promises a 90-day "satisfaction guarantee", but the binding terms allow 10 days from purchase, for unused goods.

Our Dose Check compares each label amount with the best human study.

• AnaGain Nu: 100 mg vs 100 mg a day for 8 weeks in 21 people. Matches the studied dose; the study is small and supplier-run.
• Biotin: 500 µg vs no trial in people without a deficiency.
• Zinc: 10 mg, 100% of the daily reference; the review abstract gives no doses.
• Silica, MSM, nettle, alfalfa: no human hair trials to compare with.

The label says 2 capsules a day, about 30 minutes before a meal, with 300 ml of water. A bottle lasts a month; the AnaGain study ran 8 weeks, and hair changes usually take 3 months or more to show.

Our Transparency Score checks five things a buyer can verify. Locerin scores 2 out of 5.

• Label with doses: yes. All 16 ingredients are dosed.
• Identifiable company: no. The Swiss site names Key Player Limited, Dubai Airport Freezone; the English site names only "Locerin.com" in Hong Kong. The brand is a NuviaLab trademark. No manufacturer is named.
• Refund terms in writing: yes. 10 calendar days from purchase, unused goods only.
• Independent testing shown: no.
• Study on the finished product: no. Only the supplier's pilot on one of 16 ingredients. NuviaLab also says AnaGain Nu "leads to 78% hair growth after just 3 months"; we could not find a source for that figure.

Correction. An earlier version of this review named a medical reviewer we cannot identify, and claimed GMP manufacture and free shipping. We have removed these.

Prices when we checked in September 2026:

• Swiss site (where our link leads, in German): CHF 49.99 for 1 bottle, CHF 99.98 for 3, CHF 149.97 for 6, plus shipping.
• US site and NuviaLab: $49.99, $99.98, $149.97. UK: £39.99, £79.98, £119.97.

90 days or 10 days? The sales page says that if your hair has not become "significantly stronger, thicker and full" within 90 days, you should "contact us". It does not describe a refund. The binding terms allow withdrawal only "within 10 calendar days from the date of purchase", in writing, for goods with no signs of use, and state that EU law does not apply. A 90-day trial falls outside that window.

• Biotin and blood tests: laboratory guidance says supplemental biotin can cause clinically significant errors in some tests, and the FDA has received reports of falsely low troponin results, a test used to diagnose heart attacks. The dose needed varies by test, so tell your doctor and lab you take it.
• AnaGain Nu: no adverse events were reported in the pilot.
• Too much selenium can itself cause hair loss, according to the AAD; Locerin's 55 µg is within the daily reference.

There is no clinical study on Locerin itself.
