Discolored, thickened, or damaged nails affect confidence and daily comfort more than most people admit. Whether caused by fungal infection, aging, or repeated polish use, nail concerns rarely resolve on their own and often worsen without consistent intervention.
How we choose
This article highlights eight useful products that tackle these problems through different approaches: drug-grade antifungals, botanical homeopathic formulas, renewal oils, and comprehensive foot care systems. Each option serves a distinct need, routine style, and severity level—so you can find a fit that works with your lifestyle rather than against it.
Our 8 Picks
Kerasal Nail Renewal, Restores Appearance of Discolored or Damaged Nails, 0.33 fl oz (Packaging May Vary)
What it is
A topical nail renewal solution with urea and lactic acid designed to improve the appearance of discolored, thickened, or damaged nails.
Why it's worth it
Well suited to those seeking a daily nail care treatment that exfoliates and hydrates as it works. The precision applicator allows targeted application directly to affected nail areas, and the included nail files help prep nails for better absorption. A good fit for people managing roughness, ridges, or discoloration who want a straightforward, mess-free routine.
Caveat
Visible improvement requires consistent daily use over an extended period, and results vary by individual nail condition.
Fungi-Nail Anti-Fungal Liquid Solution, Kills Toe Fungus and Tolnaftate & Clinically Proven to Cure and Prevent Fungal Infections, 1 Oz (Pack of 1)
What it is
A maximum-strength antifungal liquid with 1% tolnaftate and essential oils for treating toe and foot fungus around and under nails.
Why it's worth it
Well suited to those wanting an over-the-counter antifungal with a pinpoint applicator for precise delivery around infected areas. The formula combines tolnaftate with tea tree oil, aloe vera, and lavender to address fungus while conditioning surrounding skin. A good fit for people dealing with athlete's foot or fungal infections seeking a mess-free, targeted treatment.
Caveat
The pinpoint applicator may not reach fungus deep under the nail plate where the infection originates.

What it is
An extra-strength antifungal solution with 10% undecylenic acid and a blend of botanical ingredients for treating toe, finger, and foot fungus.
Why it's worth it
Well suited to those seeking a plant-enriched antifungal with a built-in brush for controlled application around nail edges and cuticles. The brand states the formula penetrates and absorbs into the skin around infected nails. A good fit for people who prefer a USA-made option with a comprehensive ingredient list and want a clear, non-staining finish.
Caveat
The brand recommends allowing five minutes for absorption before covering, which may not suit those needing a quick-dry option.
Probelle Natural Renewal Nail Oil, Nail Color Restoration, Clear Topical Solution, Restores Appearance of Discolored or Damaged Nails, .5 oz/ 15 ml
What it is
A plant-based nail oil formulated to restore the natural color and appearance of discolored or damaged fingernails and toenails.
Why it's worth it
Well suited to those preferring a naturally derived, USA-made option for nail discoloration and thickness concerns. The oil format absorbs into the nail and surrounding skin, offering a conditioning approach rather than a harsh chemical treatment. A good fit for people with sensitive skin or those wanting a gentle, daily-use product for gradual nail appearance improvement.
Caveat
As a cosmetic nail oil rather than a drug-grade antifungal, it does not claim to cure fungal infections.

What it is
A two-step foot care system combining a tea tree oil foot soak with Epsom and sea salts plus a nail repair oil for damaged nails and cuticles.
Why it's worth it
Well suited to those wanting a comprehensive routine that addresses both foot environment and nail appearance together. The soak softens callused skin and prepares nails, while the nail oil nourishes dry, brittle nails and cuticles. A good fit for people who enjoy spa-style self-care and want to tackle multiple foot concerns—odor, roughness, and nail damage—in one kit.
Caveat
The two-step process requires more time and commitment than a single-product treatment, and the soak basin is not included.

What it is

The brand states the formula absorbs beneath the nail surface to target problem areas directly. A good fit for people who prioritize natural and organic certifications in their personal care products and want a treatment free from synthetic chemicals.
Caveat
Homeopathic formulations may work more gradually than conventional antifungal medications, and the 11ml size requires repurchasing for extended treatment.

What it is
A pen-format antifungal treatment with 25% undecylenic acid, tea tree oil, and oregano oil for targeted nail fungus application.

The concentrated formula with high-percentage undecylenic acid delivers active ingredients directly to affected nail areas. A good fit for busy individuals who need a travel-friendly option they can apply discreetly at work or on the go.
Caveat
The pen format holds a limited amount of product, and the brand recommends 15-30 days of use depending on nail thickness, which may require multiple pens for full treatment.

What it is

The formula combines nail-hardening and hydrating ingredients to address breakage and thickness concerns simultaneously.

This is a nail strengthener and conditioner rather than a drug-approved antifungal treatment, so it does not claim to cure fungal infections.
