WellaNail review: the nail grows out on its own clock, not the seller's.

WellaNail is a topical oil from the brand WellaNail, operated by UAB Rara Digital, sold as a cosmetic product for the appearance of nails affected by discoloration, thickening or brittleness. The seller's own materials name three ingredients in the formula: rosemary, castor and green tea oil, described only in marketing prose, with no published INCI list or stated concentration in any text of the checkout, product pages, upsells or legal pages we read on September 1, 2026. The seller's own hero photo shows a bottle labeled "10ml," but since no text in the funnel repeats that number, we treat the bottle volume as unconfirmed and photo-only, not a published fact. The product's own name includes the words "Fungus Treatment Oil"; we use that as its name, not as our own description of what it does, since we treat it strictly as a cosmetic, not a drug.

Four package sizes, read directly from the seller's own checkout on September 1, 2026, all in US dollars: 1 bottle at $45.99 plus $3.99 shipping ($49.98 total); 2 bottles at $37.99 each plus $4.99 shipping ($80.97 total); 3 bottles at $33.99 each plus $5.99 shipping ($107.96 total); 4 bottles at $30.99 each, the lowest per-bottle price, plus $6.99 shipping ($130.95 total). Shipping is never free; it scales with pack size. A $5.99 "Shipping Protection" add-on appears as a checkbox at checkout, priced once per order; today's payload reads preselect_warranty: false, meaning it is not pre-checked, but a dated Trustpilot complaint (June 28, 2026) says it arrived pre-checked anyway, so check that box yourself before you pay. None of this includes the three optional one-click add-ons that appear after you pay, previewed and detailed on this page.

Not in our voice. Thickened, discolored or crumbling nails can be a sign of onychomycosis, a diagnosable fungal infection, and that's a question for a doctor or podiatrist, not a cosmetic oil review. WellaNail's own sales page uses treatment language throughout, including a badge that reads "FDA-CLEARED INGREDIENTS"; the same seller's own Terms & Conditions state, in a separate section, that "neither the Product(s) nor any statements regarding them have been evaluated by the U.S. Food and Drug Administration (FDA), and the Product(s) are not intended to diagnose, treat, cure, or prevent any disease." Those two passages, from the same site, contradict each other. We describe WellaNail only as a cosmetic oil for the appearance and feel of nails and skin, never as a fungus treatment.

Three named oils, per the seller's own marketing copy: rosemary, castor and green tea oil. Rosemary and green tea both show antifungal and antimicrobial activity in lab (in vitro) studies; that's not the same as a clinical result on a human nail, and no dose or concentration is published here. Castor oil is a genuine emollient, the one effect on this list that's honestly plausible as a cosmetic: it conditions the nail plate and surrounding skin. There is no tea tree oil and no undecylenic acid anywhere in WellaNail's own materials, despite those being the ingredients most associated with over-the-counter antifungal products; we don't invent ingredients the seller doesn't list. No INCI list and no percentage appears anywhere in the funnel we read on September 1, 2026: NOT PUBLISHED. The seller's own hero photo shows "10ml" printed on the bottle label, but that number appears in no text anywhere in the checkout, product pages, upsells or legal pages, so we treat the bottle volume as unconfirmed, photo-only, not a published fact.

No subscription in the checkout we read on September 1, 2026: the site's own subscription module is configured off in the payload we captured, and no recurring-billing tab appears on the page. It is not a one-screen checkout, though. Right after you pay, the seller's own post-payment flow offers three separate one-click add-ons, each a new charge on the same card: more of the same oil at a discounted unit price, a UV/LED nail lamp (a different product), and a $12.95 "Premium Shipping" upgrade. Each one has its own "No thanks" decline link. A dated Trustpilot complaint (July 19, 2026) describes a single bottle order turning into charges "totaling 292 dollars," which lines up with accepting this exact chain.

A 30-day guarantee, counted from delivery, not from your purchase date, per the seller's own Returns & Cancellation policy: "You can return products purchased from us within 30 days of receiving your order for a refund or exchange..." The seller's sales page separately promises "Send your package back and get a full refund, no questions asked." The same returns policy narrows that promise sharply in its own Return Conditions section: "Health & Personal Care (including supplements, topical creams, and beauty items) cannot be returned once opened, unless defective or damaged upon arrival." WellaNail is a topical oil, so an opened, used bottle isn't eligible for a change-of-mind refund under that clause, whatever the sales page implies. Returns also need advance approval and an RMA, you pay return shipping, original shipping isn't refunded, and the seller can take up to 7 days to inspect a return before refunding.

We found no FTC action, recall, or fabricated celebrity endorsement against WellaNail. On Trustpilot, read September 1, 2026, WellaNail carries a 2.9 out of 5 TrustScore from 94 reviews, and 54% of those ratings are 1 star, against 26% five-star. The company has claimed its profile and responds to reviews, typically within about a week, which is a real signal of an operating business. Dated complaints on that profile describe a single bottle turning into "292 dollars" in charges (July 19, 2026), an unwanted $5.99 shipping-protection charge (June 28, 2026), a late order with an unanswered refund request (June 25, 2026), and the oil not working after 90 days of use (July 6, 2026). We won't repeat any of the seller's own on-page customer counts, which range from about 1,000 to over 75,000 across two pages of the same funnel, roughly a 9x spread. The seller's on-page reviews widget also shows a star breakdown and total count that is digit-for-digit identical to a sibling product's widget from the same operator, a strong sign that number is a template, not measured data.

We did not confirm an official WellaNail listing on Amazon or in any retail store during our September 1, 2026 research; the checkout we read runs direct-to-consumer through the brand's own site, and that same site's own code sets a "do not index" instruction for search engines. If you find a WellaNail listing on a marketplace, we can't vouch for whether it's the same seller or a genuine product, and the safest path is the seller's own checkout.

WellaNail is operated by UAB Rara Digital, a company registered in Lithuania (company number 306641699), with a registered address at Gedimino pr. 20, Vilnius, per the checkout's own configuration data and the site's Terms & Conditions. The same operator's name was the subject of a UK Advertising Standards Authority ruling on November 26, 2025, upheld against a different product (a portable cooler) for unsubstantiated performance claims; that ruling doesn't concern WellaNail directly, but it's a dated, public fact about how the same operator has handled advertising claims before.

People who want a low-commitment cosmetic oil for the look and feel of nails and surrounding skin, and who understand it's not a substitute for medical care. It is not for anyone with a nail that's painful, lifting from the bed, or changing shape quickly, and it is not for anyone with diabetes or a circulation problem without a doctor's input first: the seller's own funnel features a testimonial from someone with diabetes claiming the oil resolved a foot infection, and we're telling you plainly to see a doctor instead of reading that as permission. Nothing on this page is medical advice.
