Long, strong nails are a beauty goal for many people—but weak, brittle nails can make growth feel impossible. While it’s important to be honest that nails cannot dramatically grow several millimeters in just three days, certain natural remedies can strengthen nails, improve circulation, and enhance their appearance quickly, making them look healthier and slightly longer. One popular home method combines onion and toothpaste—two items easily found in your kitchen and bathroom. Let’s explore how this remedy works and how to use it safely.
Why Onion Helps Nail Growth
Onion is rich in sulfur, a mineral essential for producing keratin, the protein that makes up nails. It also contains antioxidants and antibacterial compounds that help fight nail infections and strengthen weak nail beds. When applied topically, onion juice may help improve blood circulation around the nails, which supports faster and healthier growth over time.
Why Toothpaste Is Used
Toothpaste—especially plain white toothpaste—contains ingredients like calcium, baking soda, and mild cleansing agents. These can help clean the nail surface, reduce yellowing, and temporarily harden soft nails. When combined with onion juice, toothpaste acts as a carrier that keeps the remedy in place and enhances the strengthening effect.
How to Prepare the Onion and Toothpaste Nail Treatment You will need: 1 small onion 1 teaspoon white (non-gel) toothpaste Cotton swab or clean brush
Steps: 1. Grate or blend the onion and extract 1–2 teaspoons of fresh onion juice.
2. Mix the onion juice with the toothpaste to form a smooth paste.
3. Using a cotton swab, apply the mixture evenly to clean, dry nails.
4. Leave it on for 10–15 minutes.
5. Rinse thoroughly with lukewarm water and gently pat dry.
6. Apply a light moisturizer or cuticle oil afterward.
Repeat this once daily for 3 days.
What Results Can You Expect in 3 Days?
After three days, many people notice: Nails feel harder and less brittle Improved shine and smoothness Reduced peeling or splitting Nails may appear slightly longer due to less breakage
Remember, real nail growth takes time, but stronger nails break less, which helps length retention.
Important Tips and Warnings Always do a patch test first to avoid irritation. Avoid this remedy if you have cuts, infections, or very sensitive skin. Do not leave the mixture on overnight. The onion smell may linger briefly—washing with lemon water can help.
Final Thoughts
The onion and toothpaste remedy is not magic, but it can be a quick, natural way to strengthen nails and boost their appearance in just a few days. For long-term nail growth, combine this method with good nutrition, hydration, and regular nail Care
