Home remedies for brittle toenails

Toenails can split or peel after repeated wetting and drying, pressure from tight footwear, picking, or frequent polish and remover use. A nail that becomes thick, yellow, crumbly, separated from the bed, or develops debris underneath may reflect nail fungus. Other causes include skin inflammation, injury, or a health problem affecting nail growth, so brittle texture alone is not enough to identify the cause.

Trim straight across after bathing when the nail is softer, and smooth sharp edges with a clean file. Wear roomy, breathable shoes and change damp socks promptly. Dry carefully between the toes, avoid sharing nail tools, and do not tear loose nail layers away. Pause gel polish, acrylic products, and harsh remover while the nail recovers. Moisturiser on the surrounding skin can reduce cracking, but it will not treat an underlying infection.

Book a medical review if one nail changes progressively, several nails become thick or discoloured, the nail lifts, or there is pain, swelling, pus, or bleeding. People with diabetes, reduced circulation, or a weakened immune system should seek advice promptly for foot or nail changes. Testing may be needed before antifungal treatment because injury and infection can look alike.

Could this be nail fungus or damage from footwear? Does the nail need a sample test? Which trimming and footwear changes fit my situation? Should I avoid salon treatments while it grows out?
