While clear nails indicate healthy and adequately hydrated nails, sometimes it might be the opposite. Pay attention if your nails are being overly hydrated, which makes one's nails transparent or clear. If your nails are brittle, easily flexible, then they're excessively hydrated. Eat and drink water in moderation. Try to use gloves whenever possible for housework. Apply lotion every night before sleep. Doing so can make your nails healthy and back to their natural-looking form.
