If someone told you they had a multi-step 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. 

It’s common for people to neglect their nails, which may be one reason so many struggle to grow long tips. Here, nail experts share their 5 best tips for achieving substantial nail growth and keeping them strong. Yes, it may take a bit more T.L.C. than you’re used to but it will all be worth it the day you nail that DIY salon-grade mani.

“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 impacted 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. 

If you don’t have one on hand already, here’s 10 different A+ oils to choose from. 

Specifically, biotin has been shown to support thickness and firmness of nails in several human studies.* One moderately-sized human study found that those who took biotin supplements had 25% thicker nail beds 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. 

In addition, you can look to collagen supplements. Studies indicate that collagen supplements can support healthy nail growth.* That’s because collagen supplements contain hydrolyzed collagen peptides, which are short chains of amino acids. These amino acids are the building blocks for keratin—aka, what your nails are made of. For example, one study found that when people took collagen daily for 24 weeks, their nail health was better maintained, including faster growth rates, reduced breakage, and improved appearance.* 

• Citrus fruits: Citrus fruits are a great source of B vitamins, especially B9. Also known as folate, vitamin B9 contributes to red blood cell formation and the development of new blood cells. For this reason, falling short of adequate folate can result in brittle nails. 
• Peanuts: Peanuts are rich in iron, which is also essential for healthy nails. In general, iron helps oxygen reach the cells. Hence, why a significant lack of iron can lead to vertical ridges in the nails. 
• Walnuts: Walnuts are a popular plant-based source of omega-3 fatty acids, which helps to support skin hydration. Again, a hydrated cuticle is key for healthy nails that grow to their full potential, so this step shouldn’t be overlooked. 

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.

Here’s 8 more derm-approved tips to kick this habit for good if you’re struggling.

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, Dana 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. Dana herself created one of the most classic growth products on the market: The Nail Renewal System. This kit contains 3 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.
