In fair-skinned people: Could be melanoma (nail-bed cancer)—even without pain
Urgent: See a dermatologist immediately if it’s new, widening, or on one nail only
(Note: In darker skin tones, benign stripes are more common—but still monitor for changes)
Daily Habits for Healthier Nails
Hydrate: Dehydration shows in dry, brittle nails
File gently: Use a glass or fine-grit file; never rip hangnails
Go polish-free 1–2 weeks per month
Eat protein + healthy fats: Nails are made of keratin—build them with eggs, fish, beans, and avocado
