Brittle nails treatment and prevention

Nails can weaken when they repeatedly move between wet and dry conditions, contact detergents or solvents, or are filed and buffed aggressively. Biting, picking, pushing back cuticles and extensions can add mechanical stress. Brittle nails may also accompany eczema, psoriasis, fungal infection, thyroid or nutritional problems, so prevention should not replace an assessment when changes persist. Notice whether one nail or many are affected, whether the surface is ridged or pitted, and whether there is pain, discoloration or lifting.

Keep nails at a practical length and file catches soon after they appear. Wear gloves for dishes, cleaning and gardening, with a cotton liner if moisture collects. Dry hands and nail folds thoroughly, then use a fragrance-free moisturizer. Remove polish gently and take breaks from gel, acrylic and strong remover products. Do not use nails as tools or scrape under them. Balanced meals support normal growth, but supplements should be considered only after a clinician has reviewed your diet, medicines and symptoms. Treat an identified infection or skin condition as directed.

Arrange a review if careful protection does not help, if the change spreads to other nails, or if the nail becomes thick, crumbly or detached. Prompt assessment is needed for increasing pain, redness, warmth, pus, fever, a changing dark mark or bleeding without a clear injury. Do not cover a concerning nail with cosmetic products before it has been examined.

Which exposures may be weakening my nails? Should infection or a skin condition be tested for? Are supplements appropriate for my diet? What nail length, moisturizer and protective routine fit my work?
