5 Expert-Backed Tips To Getting Long Nails That Last, Sans Breakage

If someone told you they had a multistep skin care routine they do every day, you probably wouldn't be shocked in the slightest. However, when someone mentions the phrases nail care and every day in the same sentence, you may have a few questions. 

"One of the most important aspects of a manicure is how the cuticle is cared for," board-certified dermatologist and nail expert Dana Stern, M.D., tells mbg. So while this step may seem like an occasional luxury, you may want to make it a staple in your daily routine. 

Cuticle care isn't just about looks—your cuticle has an essential function too. This means when your cuticle is in less than ideal condition (dry, peeling, etc.), that function will be affected as well. "If the cuticle compromise persists chronically, the nail will eventually grow in irregularly (white patches, bumps, thickening, discoloration)," Stern explains. 

"This is because the cuticle overlies the nail matrix, which is the nail-producing center of the nail," she continues. To sum up: Cuticle care is essential for healthy nails, growth included. 

Specifically, biotin has been shown to support thickness and firmness of nails1 in several human studies.* One moderately sized human study found that those who took biotin supplements had 25% thicker nail beds2 than the placebo group.*

If you want to learn more about the buzzy supplement, this biotin breakdown covers everything from benefits to food sources and more. 

This one should go without saying, but picking at your nails and cuticles will not support healthy nail growth. Not to mention, this can lead to serious cuticle fraying that will raise even more risks than just stunted tip growth—remember, your cuticles protect the nail.

If you have trouble fighting the urge to pick or bite, you may want to keep up with a polished manicure. This way, you're less likely to mess with your nails (as the fresh look is another reason to hold back). If you tend to bite, you may consider layering a no-bite top coat instead to remind you to keep your hands away from your face.

Navigating the world of nail systems, strengtheners, and "growth polishes"' can be a bit overwhelming. The mixed messaging gets confusing, especially because many products that momentarily strengthen the nail, in turn, actually weaken it over time. 

Here, Stern explains, "Many so-called nail strengtheners contain formaldehyde or formalin. These ingredients are very hard on the nail. Formaldehyde will initially harden the nail; however, with time, the nail becomes paradoxically brittle and is at risk for lifting or separating off of the nail bed." Further, formaldehyde can cause allergic reactions for some that may lead to irritation around the nail. 

The solution: Opt for natural, science-backed ingredients instead. Stern herself created one of the most classic strengthening products on the market: The Nail Renewal System. This kit contains three steps: a glycolic acid exfoliation prep, a priming wand, and a hydrating finish. The system will leave your nails supported for healthy growth and glowing so bright you'd think you have a top coat on.
