1. Choose a Comfortable Nail LengthAn integral part of how to make nail polish stay on longer is choosing a length for your nail that allows you to comfortably do any activity while avoiding breakage. A chipped nail can sometimes be a traumatic and painful experience. It also is one of the main causes of a ruined manicure. If you play an instrument or your job involves a lot of typing on a keyboard, a shorter nail length is the way to go. Keep your nails trimmed to a length that compliments your fingers or toes, but remember to avoid going too long unless you have resilient nails.
