Here's a report from dermatologists about healthy nails:
Myth: Always wearing dark nail polish can discolor your nails.
Fact: This is not a myth, itīs true. For some people who use darker shades of nail polish on their fingers and toes, removing the color may reveal yellowed, discolored nails. "Darker colored polish, like blue, brown, burgundy and black, can temporarily stain the nail plate. The staining will resolve over several weeks if the same color of polish is not reapplied," said Dr. VanBeek. "The staining is neither bad nor harmful for your nails." To prevent this from happening to unblemished nails, apply an extra layer of base coat first before using the nail color.
Myth: Fungal infections of the nail can be effectively treated with topical products.
Fact: Despite the wealth of over-the-counter products available that claim to treat fungal nail infections, the only way to cure an infection is to see a dermatologist. "Over-the-counter topical medications donīt penetrate the nail and therefore, arenīt as effective as oral prescription medications," Dr. VanBeek said. "A dermatologist can prescribe the proper medication to eradicate the infection in most cases." One of the best ways to deal with fungal nail infections is to prevent them from happening. Since nail fungus thrives in warm, damp environments, Dr. VanBeek recommends that you keep your feet clean and dry, refrain from sharing towels and wear sandals in public shower areas.
