Permanent nail polish typically lasts 2 to 4 weeks on natural nails, depending on several factors:

• Nail Type: Oily or weak nails may cause the polish to lift sooner.
• Daily Activities: Frequent exposure to water, cleaning products, or rough surfaces can reduce its longevity.
• Application Quality: A professional application with high-quality products ensures better durability.
• Aftercare: Keeping nails hydrated and protecting them from harsh chemicals can extend wear time.

If nail growth becomes noticeable, most people opt for a touch-up or removal after 2-3 weeks to maintain a fresh look.
