Nail conditions can reflect underlying health issues or arise from external factors. Common conditions include fungal infections (onychomycosis), which cause thickened, discolored nails, and brittle nails resulting from excessive exposure to water or chemicals. Psoriasis can lead to pitting, discoloration, and crumbling nails, while paronychia refers to painful inflammation around the nail bed, often due to infection.

Beau’s lines are horizontal ridges caused by temporary growth interruptions, and clubbing indicates oxygen deficiency in the body. Proper nail hygiene, balanced nutrition, and avoiding harsh chemicals are essential for nail health. Early diagnosis and appropriate treatment can prevent complications and restore healthy nails.
