- Aging
Nails naturally become thinner, drier, and more fragile with age.
This is common and doesn’t necessarily indicate disease.
- Fungal Infection
A fungal nail infection can cause nails to become thick, discolored, brittle, crumbly, or separated from the nail bed.
Fungal infections usually require appropriate treatment rather than simply applying strengthening products.
- Skin Conditions
Conditions such as psoriasis, eczema, or lichen planus can affect the nails.
Changes such as pits, ridges, discoloration, or separation from the nail bed may provide clues.
- Repeated Trauma
Biting your nails, picking at the cuticles, using nails as tools, or repeatedly hitting the fingertips can damage the nail plate.
Keeping nails at a moderate length and avoiding unnecessary trauma can help them grow healthier.
