In This Review:
If you have noticed more hair on your pillow, in the shower drain, or on your brush than you used to, you are far from alone. Diffuse hair thinning in women is one of the most common — and least discussed — conditions affecting quality of life, with hormonal shifts, nutritional gaps, and chronic stress all playing a role at once. The challenge is not just finding a product; it is finding one with a formula worth trusting.
Locerin is a multi-ingredient capsule supplement manufactured by NuviaLab, a European supplement company with a growing catalog of health products. It positions itself as a comprehensive internal hair support formula, combining 16 active ingredients — including three patented complexes — to address multiple root causes of hair loss simultaneously. That is an ambitious claim, and this review is going to examine it closely.
Over the following sections, we will break down every major ingredient against the available clinical evidence, identify where the formula is genuinely strong, and be equally direct about where it falls short. By the end, you should have a clear picture of whether Locerin is worth adding to your routine — and, just as importantly, whether it is the right fit for your specific situation.
What Is Locerin?
Locerin is a dietary supplement produced by NuviaLab, a European manufacturer specializing in health and beauty nutraceuticals. It is formulated specifically for women experiencing hair thinning, slow growth, or reduced hair quality, and comes in the form of easy-to-swallow capsules.
Each pack contains 60 capsules — a one-month supply at the recommended dose of two capsules per day, ideally taken 30 minutes before a meal with approximately 300 ml of water. The manufacturer recommends consistent use for at least 90 days to fully assess results.
The formula is organized around three patented complexes — AnaGain™ Nu (organic pea sprout extract), SeLECT® (a selenium-biotin-zinc mineral blend), and BioPerine® (piperine extract) — supported by a range of plant extracts, vitamins, and minerals. The core claims include inhibiting hair loss, stimulating new growth, strengthening existing strands, and helping to maintain natural hair colour.
Pricing at the time of writing sits at approximately $49.99 for a single one-month supply, with multi-bottle packages reducing the per-month cost significantly. The product is available exclusively through the official Locerin website — it is not stocked in pharmacies or on third-party retail platforms.

Ingredient Analysis
This is the section that separates a genuine review from a marketing summary. Locerin contains 16 ingredients, which is more than most competing supplements. More ingredients does not automatically mean better results — what matters is whether the right ingredients appear at meaningful concentrations and whether the evidence supporting them is credible. Here is the breakdown.
AnaGain™ Nu (Organic Pea Sprout Extract)
This is the headline ingredient and the most scientifically documented component of the formula. AnaGain™ Nu is a water-soluble extract derived from organic pea sprouts (Pisum sativum L.), developed by Mibelle Group Biochemistry in Switzerland.
A clinical study published in Phytotherapy Research in 2019 evaluated 21 volunteers with mild-to-moderate hair loss, who received 100 mg of the extract orally per day for eight weeks. Researchers observed a statistically significant reduction in hair loss after 28 days of treatment (p < 0.002), with hair loss down 34% after one month and 37% after two months. The mechanism centres on the ingredient's ability to stimulate FGF7 (fibroblast growth factor-7) and noggin expression in dermal papilla cells — the signalling pathway that initiates the anagen (active growth) phase of the hair cycle.
It is worth noting an important caveat here: the study was small (21 participants), conducted over a relatively short duration, and was partly funded by the company that holds the patent. Independent, large-scale randomised controlled trials have not yet been published. The evidence is promising and mechanistically credible, but it remains preliminary. Locerin uses 100 mg per serving, which matches the dose studied.
Horsetail Extract (Equisetum arvense)
Horsetail is one of nature's richest sources of organic silica — a mineral that supports the structural integrity of hair strands. Silica plays a documented role in maintaining hair elasticity and tensile strength. Research from traditional botanical medicine, as well as more recent observational data, supports the use of horsetail for improving hair and nail quality, though large-scale clinical trials are still limited. As a complementary ingredient in a multi-component formula, it contributes meaningfully to the overall composition.
Bamboo Stem Extract
Like horsetail, bamboo stem is a concentrated silica source — some extracts contain up to 70% silica content. It is often paired with horsetail in hair formulas for this reason. While independent clinical trial data specific to bamboo-derived silica for hair loss is limited, its inclusion reinforces the formula's silica supply, which may reduce brittleness and support strand thickness over time.
Nettle Leaf (Urtica dioica)
Nettle has been studied for its potential to inhibit the enzyme 5-alpha-reductase, which converts testosterone to DHT — the androgen most closely linked to female pattern hair loss. Research published in journals covering phytotherapy has demonstrated nettle's in vitro capacity to inhibit this conversion, though in vivo human trials are fewer and typically smaller in scale. Nettle also provides a natural source of silicon, vitamin C, vitamin K, and several B vitamins.
SeLECT® — Selenium, Biotin, and Zinc Complex
This patented trio addresses three common nutritional deficiencies associated with poor hair health. Selenium supports the body's antioxidant defences and is involved in thyroid function, disruption of which frequently presents as hair thinning. Zinc is essential for follicle repair and growth, and deficiency is well established as a contributor to telogen effluvium. Both minerals have solid evidence for hair health in the context of deficiency.
Biotin (vitamin B7) requires a more nuanced discussion. It is widely marketed as a hair growth supplement, but a systematic review published in the Journal of Clinical and Aesthetic Dermatology found that the utility of biotin as a hair supplement "is not supported by high-quality studies" in individuals who are not biotin-deficient. In cases of true deficiency — which can occur due to dietary restriction, pregnancy, antibiotic use, or certain medications — biotin supplementation shows clear benefit. For individuals already meeting adequate intake, the effect is less certain. Locerin's biotin inclusion makes the most sense for users who may have subclinical deficiency.
BioPerine® (Black Pepper Extract / Piperine)
BioPerine is a patented, standardised piperine extract with a well-documented role as a bioavailability enhancer. Research indicates that piperine can increase the absorption of selenium, iron, vitamin B6, and beta-carotene by modulating intestinal transport mechanisms. Its inclusion in Locerin is functionally important — it helps ensure the other ingredients are absorbed effectively rather than passing through largely unmetabolised.
Magnesium (Aquamin™)
Aquamin is a marine-derived magnesium sourced from the waters off the Irish coast, a form associated with higher bioavailability than standard magnesium oxide. Magnesium supports cell division and protein synthesis, both of which are relevant to hair follicle cycling. While not typically marketed as a primary hair supplement, maintaining adequate magnesium levels supports the broader hormonal and cellular environment that hair growth depends on.
Alfalfa, MSM, and Additional Vitamins
Alfalfa contributes additional flavonoids and minerals associated with scalp health and natural hair colour maintenance. MSM (methylsulfonylmethane) is an organic sulphur compound that supports the permeability of cell membranes, potentially aiding nutrient uptake at the follicle level. Niacin (vitamin B3) promotes microcirculation in the scalp, helping nutrients reach the follicle. Vitamin C supports collagen production, which strengthens the structural tissues surrounding hair roots. Vitamin B6 is involved in amino acid metabolism and is co-transported more efficiently alongside BioPerine.

Pros & Cons
Pros
- AnaGain™ Nu is the strongest ingredient in the hair supplement category. It is one of the few hair-specific ingredients supported by a peer-reviewed pilot trial published in an indexed journal, making it a meaningful step above generic "hair blends."
- Three patented complexes in one formula. AnaGain™ Nu, SeLECT®, and BioPerine® are each standardised, quality-controlled forms of their respective ingredients — a sign of manufacturing rigour that many competitors skip.
- BioPerine® enhances absorption of co-ingredients. This is not just a filler. Inclusion of a bioavailability enhancer addresses one of the most common shortcomings in multi-ingredient supplements: absorbing what you are taking.
- The silica content is genuinely high. Having both horsetail and bamboo stem extract provides a meaningful silica load from two distinct sources, which may benefit users who have dry, brittle, or breakage-prone hair.
- Manufactured by an established European company with a 90-day guarantee. NuviaLab operates with European manufacturing standards, and the money-back policy provides a reasonable window to assess whether the supplement delivers results.
- Dosing is well-matched to clinical studies. The 100 mg AnaGain™ Nu dose aligns with the amount used in the published pilot trial, which is not always the case with supplements that cite research at doses they do not actually deliver.
Cons
- The AnaGain™ Nu research base remains limited. The primary study involved 21 participants and was partly industry-funded. Until larger, independent trials confirm these results across diverse populations, confidence in this ingredient should remain measured rather than absolute.
- Biotin's benefit depends on individual biotin status. For women who are not biotin-deficient — which is most women — the biotin in Locerin may contribute less than its prominent marketing presence suggests. If you eat a varied diet and have no absorption issues, do not expect biotin alone to drive the results.
- Only available online. Locerin cannot be purchased from pharmacies or major retail platforms. While the official website offers secure ordering, this requires planning ahead and means the product is not immediately accessible if you run out.
- Results require consistent long-term use. The manufacturer acknowledges that visible improvement takes four to twelve weeks for most users, and some user reports suggest the clearest results only emerge after four to five months. This is not a rapid-response supplement — and the cumulative cost of multi-month use adds up.

Who Should Consider Locerin?
Locerin is most likely to be a useful fit for women who are experiencing diffuse hair thinning — particularly thinning associated with nutritional shortfalls, post-pregnancy hair loss, the hormonal fluctuations of perimenopause, or chronic stress-related telogen effluvium. The formula's multi-pathway approach (targeting growth signals, scalp nutrition, DHT modulation, and mineral absorption) makes it better suited to this kind of multi-factorial hair loss than to any single-cause scenario.
It is also a reasonable choice for women who have already made lifestyle adjustments — diet improvements, stress reduction, better sleep — and want internal nutritional support to complement those changes. Users in this situation are most likely to see results within the typical four-to-twelve-week window.
Women whose hair loss is associated with a confirmed nutritional deficiency in zinc, selenium, or magnesium may see a more pronounced response, as correcting documented deficiencies tends to produce more reliable results than supplementing on top of adequate levels.
Locerin is less likely to be the right primary solution for women with clinically diagnosed androgenetic alopecia (female pattern baldness) at an advanced stage, those with autoimmune-related hair loss (such as alopecia areata), or individuals with significant thyroid conditions that are not yet well-managed. In these cases, supplementation may play a supporting role, but medical assessment and treatment should come first.
Additionally, the product is not suitable during pregnancy or breastfeeding, and women taking medications that affect hormone metabolism or who have chronic renal or hepatic conditions should consult their GP before starting any new supplement regime.
Frequently Asked Questions
How long does it take for Locerin to show results?
Most users report early improvements — less hair shedding, improved texture — within four to eight weeks of consistent use. More significant changes in density and growth tend to become visible between months two and four. Some users note that a four-to-five-month course was required before they saw meaningful results in thickness. Because hair grows slowly by nature, patience is genuinely necessary with any internal supplement, not just Locerin.
Does Locerin work for all types of hair loss?
Locerin is most effective for diffuse hair thinning caused by nutritional gaps, hormonal fluctuations, post-pregnancy shedding, or chronic stress. It is not a treatment for scarring alopecia, alopecia areata, or androgenetic alopecia at an advanced stage, and the manufacturer does not position it as one. Women with these conditions should seek specialist dermatological advice rather than relying on a supplement as their primary intervention.
Are there any side effects from taking Locerin?
Locerin is formulated from natural ingredients, and the manufacturer states it should not cause side effects in healthy adults who are not allergic to any component. A minority of users report mild gastrointestinal discomfort in the initial days of use; taking the capsules with food rather than before a meal typically resolves this. As with any supplement, individuals with known ingredient allergies, chronic health conditions, or who are on regular medication should review the label carefully and consult a healthcare professional before starting.
Can I take Locerin alongside other supplements?
In most cases, yes — but with some caution. If you are already taking a multivitamin that contains biotin, zinc, or selenium, it is worth checking that your combined intake does not exceed established upper tolerable levels for these nutrients. High-dose biotin (well above typical supplement amounts) has been shown to interfere with certain immunoassay-based lab tests, which is relevant if you have routine bloodwork scheduled. Discuss with a healthcare provider if you are unsure about any combinations.
Is Locerin worth the cost compared to other hair supplements?
At approximately $49.99 per month, Locerin sits in the mid-tier of the hair supplement market — less expensive than premium brands like Nutrafol but more than basic biotin-only products. The differentiation lies in the inclusion of AnaGain™ Nu (a clinically studied, patented ingredient), the bioavailability-enhancing BioPerine®, and the multi-deficiency approach. Whether it represents value depends largely on the user's specific needs and how their body responds. The 90-day guarantee does reduce the financial risk of a trial significantly.
Final Verdict
Locerin occupies a credible middle ground in a market crowded with under-dosed, under-evidenced products. Its headline ingredient, AnaGain™ Nu, is one of the better-supported hair-specific compounds available in a supplement format — backed by a peer-reviewed pilot study at a dose that matches what Locerin actually delivers. The addition of BioPerine® to enhance nutrient absorption is a thoughtful formulation decision that many competitors overlook. And the inclusion of both horsetail and bamboo as dual silica sources, alongside copper for hair pigmentation and a mineral complex for follicle nourishment, gives the formula meaningful breadth.
At the same time, intellectual honesty requires acknowledging what the evidence does and does not support. The clinical base for AnaGain™ Nu, while promising, remains small and partly industry-funded. Biotin's role in hair health is genuinely overstated by the supplement industry as a whole, and Locerin is not immune to this. And results — as the manufacturer and many verified users confirm — take months to accumulate, not days.
The overall assessment: Locerin is a well-constructed supplement for women dealing with the kind of hair loss that sits at the intersection of nutritional insufficiency, hormonal change, and lifestyle stress. It is not a shortcut, and it is not for everyone — but for the right candidate who is prepared to commit to a 90-day trial, the formula gives a genuine reason for cautious optimism. The money-back guarantee makes the trial financially manageable if results do not meet expectations.
Rating: 3.9 / 5.0 — Recommended for women with nutritional-deficit or hormone-related hair thinning who are ready for a multi-month commitment to a well-formulated internal support supplement.
