These products are called nail polish strengtheners (or just nail strengtheners), which can easily be added to your existing nailcare routine in the form of a fast-acting and easy-to-apply treatments that can be applied anywhere from daily to biweekly depending on the formula.
Even if you don't normally receive gel and acrylic manicures, your natural nails could always use some TLC to help them look their best.

What should I look for in a nail strengthener?
According to Brendan Camp, MD, double board-certified dermatologist at MDCS Dermatology, "nail strengtheners fortify the nail to support its health and ability grow." He explains that nail polish strengtheners are often formulated with nourishing ingredients such as proteins, vitamins, and minerals to prevent nails from becoming dry, brittle, and cracked while addressing present damage.
If you were wondering if nail strengtheners perform miracles, the answer is that they're not magic and take consistency. When you decided to add a nail polish strengthener to your nailcare routine, make a deal with yourself to commit to following the product's recommended use. "The regular use of a nail strengthener can potentially improve the overall quality of the nail," Camp says. "Strengtheners are good products to use if your nails have been subjected to many treatments that have left them brittle, dry, or slow growing."
He also reminds me that our nails have a slower growth cycle than you may think. "It can take three to six months for your fingernails to grow out," says Camp. "They need to be used consistently over time." While some of these products may have a gentle enough formula to be used daily, others may only require biweekly use. There are also products on the market with multipurpose formulas that can be used as a nail treatment, polish primer, and base coat (which happen to be some of my personal favorites).
How should I use a nail strengthener?
It might sound counterintuitive, but when it comes to getting the most out of your nail polish strengtheners, less is more. It's important to follow directions when using these products and to take note of how your skin and nails respond to product application. "Overuse of nail strengtheners can cause the opposite of the desired effect by causing dryness or irritation of the surrounding skin," Camp explains. Harsh ingredients in formulas like formaldehyde are known to be the biggest culprits. Luckily, there are a lot of next-gen options on the market.
If you're struggling with chronically damaged nails, Camp says that a using nail polish strengthener isn't enough. "In addition to nail polish strengtheners, maintaining a healthy diet and avoiding treatments that can damage the nail and cuticle can improve nail growth," he says. Following all of these tips can help you achieve stronger, healthier nails.
