Toxic Chemicals in Nail Polish: Risks You Should Know Before Your Next Manicure

Glossy, colourful nails can instantly lift your look and boost confidence. But behind the beauty, nail polish often hides harmful chemicals that can damage your nails and even affect your overall health. With recent bans in Europe on toxic ingredients, it’s time to understand what’s really inside your favourite nail polish.

Why Nail Polish May Be Harmful to Your Health

Many nail polishes contain chemicals that weaken nails, dull their shine, and may trigger infections. Prolonged exposure to these toxins can cause serious health risks beyond nail damage, including respiratory problems and reproductive health issues.

Europe Bans TPO in Nail Polishes

A major step towards safer beauty products came when the European Union banned trimethylbenzoyl diphenylphosphine oxide (TPO) from 1 September 2025.

• Why the ban? TPO is linked to fertility problems, skin allergies, and reproductive health concerns.
• Impact on salons and brands: Nail salons across Europe must now remove TPO-based products and switch to safer, TPO-free alternatives.

This move highlights the importance of checking product ingredients before your next manicure.

Other Toxic Ingredients Lurking in Nail Polish

While TPO is currently in the spotlight, several other harmful chemicals are often present in commercial nail paints:

• Formaldehyde - Triggers skin irritation and allergies.
• Toluene - Causes headaches, dizziness, and breathing issues.
• Dibutyl phthalate (DBP) - Known to harm reproductive health.

Breathing in the fumes of these chemicals during regular use can affect your respiratory system over time.

How to Protect Your Nails from Damage

Want to enjoy pretty nails without risking your health? Follow these expert tips:

• Take nail polish breaks: Allow your nails to breathe for a few days each month.
• Choose “3-free” or “5-free” polishes: These formulas avoid the most harmful ingredients.
• Keep nails and cuticles hydrated: Use coconut oil, almond oil, or cuticle cream.
• Switch to acetone-free removers: They are gentler and prevent dryness.
• Always use a base coat: Protects nails from staining and adds a protective layer.
• Maintain hygiene: Keep nails trimmed, clean, and dry to prevent infections.

Nail polish may seem like a harmless beauty essential, but the hidden toxic ingredients can have lasting effects on your health. With growing awareness and regulatory bans like the EU’s restriction on TPO, it’s crucial to make smarter choices. Opt for safer nail polish brands, take regular polish breaks, and prioritise nail health over constant glamour.
