Keep in mind that caring for your nails doesn't stop at the nail itself. It also means caring for your cuticles, because “Keeping cuticles well-moisturized is one of the best ways to promote stronger, healthier nails," says Dr. Benjamin. She also suggests taking intermittent breaks from gel manicures and avoiding aggressive buffing, filing, and scraping, which can exacerbate nail brittleness and breakage.
When it comes to nail polish removers, choose one without acetone to avoid further drying out your nails. Lastly, wear gloves when working in hot water to protect your hands, and immediately follow up with moisturizer. And though most nail weakness is due to external factors, if over-the-counter and lifestyle fixes don't help, talk with your doctor to see if something else is going on.
