The Nail Files: Debunking the Biggest Myths with Science
In the ever-evolving world of beauty, misinformation spreads faster than a viral nail trend. From social media tips to old wives’ tales, it can be difficult to separate genuine advice from well-meaning myths. One of the most common claims? That your nails “need to breathe.” But is there any truth behind these ideas?
In this article, we explore several nail care myths and explain what the science actually says. Whether you're a beauty professional or simply passionate about nail health, this guide will help you make informed, evidence-based choices.
Myth #1: “Nails Need to Breathe”
This is perhaps the most widely shared myth in nail care. The belief is that wearing nail polish too often deprives your nails of oxygen, leading to weakness or discolouration.
The science:
Nails are composed of keratin, a fibrous protein also found in hair. Once the nail cells reach the surface, they are no longer living tissue. This means they do not require oxygen or nutrients in the same way your skin does. Instead, the nail matrix — the part beneath the cuticle — is responsible for producing and nourishing new nail cells.
The reality:
Nails do not breathe. They do not absorb oxygen through the surface, and applying polish or extensions does not suffocate them. Discolouration and brittleness often stem from improper removal techniques or poor overall nail care — not from lack of air.
Myth #2: “Nail Polish Weakens Your Nails”
Many believe that constant application of nail polish leads to thin, fragile nails.
The science:
The polish itself isn’t inherently harmful. However, repeated use without breaks, or using products with harsh chemicals like formaldehyde or toluene, can contribute to nail dryness. Additionally, aggressive removal methods — especially scraping or peeling — can strip the top layers of the nail plate, leading to thinning.
The reality:
It’s not the polish — it’s the process. Choosing high-quality, nourishing formulas and removing them properly can help preserve nail strength.
Myth #3: “Acrylic and Gel Nails Always Damage Natural Nails”
This myth has persisted for years, with many avoiding nail enhancements due to fears of permanent damage.
The science:
When applied and removed correctly by a trained professional, acrylic and gel systems do not inherently harm the natural nail. In fact, these enhancements can offer protection against environmental damage and breakage.
The reality:
Damage typically occurs when nails are over-filed, pried off, or filed too aggressively during removal. It’s not the product — it’s the technique. With proper application, regular maintenance, and gentle removal, enhancements can be worn safely.
Myth #4: “White Spots on Nails Mean Calcium Deficiency”
It’s common to hear that those little white marks on your nails are a sign of poor calcium intake.
The science:
Most white spots (known as leukonychia) are caused by minor trauma to the nail matrix — often unnoticed at the time. While nutritional deficiencies can affect nail health, calcium is rarely the cause of these specific marks.
The reality:
White spots are usually harmless and grow out over time. A balanced diet is important for overall nail health, but spotting a few white marks doesn’t necessarily mean you’re lacking in calcium.
Myth #5: “You Should Cut Your Cuticles”
Many people trim their cuticles regularly, thinking it makes the nails look tidier or promotes growth.
The science:
The cuticle acts as a protective barrier between the nail matrix and the outside world. Cutting this delicate area increases the risk of infection and inflammation.
The reality:
Rather than cutting, gently push back cuticles using a cuticle stick and apply cuticle oil daily. This maintains both hygiene and nail strength, without compromising protection.
Conclusion: Science Over Superstition
When it comes to nail care, it’s easy to fall into the trap of outdated advice or anecdotal evidence. However, understanding the science behind your nails empowers you to make better decisions — whether you’re maintaining a home routine or working as a beauty professional.
By debunking these common myths, we hope to encourage a more informed and sustainable approach to nail health. With the right knowledge and care, strong and beautiful nails are entirely achievable — no “breathing” required.
