You’ll learn what a healthy nail is

Healthy nails are smooth, strong, and pinkish with a consistent texture, while abnormalities can signal underlying issues.

Look for discolouration (yellowing may indicate fungus, white spots suggest trauma), ridges (vertical are often aging-related, horizontal may signal illness), peeling (linked to moisture or nutrient deficiencies), or unusual shapes (spoon nails hint at anemia, clubbing may reflect lung/heart conditions). Dry, brittle nails often point to thyroid or vitamin deficiencies, while swollen cuticles suggest infection.

Always assess nails in natural light and consider recent traumaβ€”persistent changes warrant medical evaluation to rule out systemic conditions like psoriasis or diabetes.
