6 Common Nail Health Myths Debunked by a Professional Technician

By Emma Reed

As a certified nail technician with years of experience, I’ve heard my fair share of nail health advice from clients—some helpful, and others downright misleading. Unfortunately, myths about nail care can lead to bad habits and unnecessary damage. Let’s set the record straight by debunking six of the most common nail health myths.

Myth #1: White spots on your nails mean you’re calcium deficient.

Truth: White spots on your nails, also known as leukonychia, are rarely related to calcium deficiency. They are more often caused by minor trauma to the nail bed, such as bumping or pinching your finger. These spots usually grow out with the nail and aren’t a cause for concern.

Myth #2: Nails need to "breathe."

Truth: Nails don’t breathe because they’re made of keratin, a protein that doesn’t require oxygen. The nail bed (the skin underneath the nail) receives oxygen and nutrients from your bloodstream. While it’s a good idea to take breaks from nail polish to prevent discoloration or dryness, your nails won’t suffocate without it.

Myth #3: Cutting cuticles is good for nail health.

Truth: Cutting your cuticles can lead to infections and damage to the nail bed. Cuticles act as a protective barrier, preventing bacteria and dirt from entering. Instead of cutting, gently push them back with a cuticle pusher and keep them moisturized with cuticle oil.

Myth #4: You can fix brittle nails with lots of water.

Truth: While hydration is essential for overall health, soaking your nails in water too often can actually weaken them. Nails absorb water, which can cause them to expand and then contract as they dry, leading to brittleness. Focus on using a high-quality nail strengthener and moisturizing regularly to maintain nail flexibility and health.

Myth #5: Gel and acrylic nails ruin your natural nails.

Truth: When applied and removed correctly by a trained professional, gel and acrylic nails should not damage your natural nails. Problems often arise from improper removal methods, such as peeling or picking at the product. Always follow professional advice and never force artificial nails off.

Myth #6: Filing nails in a back-and-forth motion is fine.

Truth: Filing nails in a back-and-forth motion can create micro-tears, which weaken the nail and lead to splitting or peeling. Always file in one direction, starting from the side of the nail and moving toward the center, to achieve smooth edges and minimize damage.
