Hot water is nail polish's natural-born enemy!" Miss Pop exclaims. "Hot water lifts the paint on your nails and causes it to chip, so wait at least six hours before submerging your hands in hot water." She suggests always wearing gloves when doing heavy-duty scrubbing work like washing the dishes, and washing your hair with medium-temperature water instead of a burning-hot stream. "As a general rule, if you're looking for a manicure that lasts, tone down the temp."
