That kind of “family trick” can sometimes help a little—but thick toenails usually have an underlying cause, so it’s worth being realistic about what a home remedy can and can’t do.
🧠 Why toenails get thick
The most common cause is a fungal infection called onychomycosis. Other causes include:
- Aging (nails grow slower and thicken)
- Repeated pressure from tight shoes
- Injury to the nail
- Skin conditions like psoriasis
If it’s fungal, no quick trick will “cure” it overnight.
🧴 Common “home trick” (what your nana likely means)
Most versions involve:
- Soaking feet in warm water
- Applying something like vinegar, baking soda, or oils
- Gently filing the nail
✔️ What this actually does
- Softens the nail
- Makes it easier to trim
- Improves appearance slightly
❌ What it doesn’t do
- It usually doesn’t eliminate infection
- Results are temporary
✅ A safer, realistic routine
1. Soften and trim regularly
- Soak feet 10–15 minutes
- Trim nails straight across
- Gently file thick areas
2. Keep feet dry
Fungus thrives in moisture:
- Change socks daily
- Use breathable shoes
3. Consider treatment if needed
If nails are very thick, yellow, or crumbly:
- Over-the-counter antifungals may help mild cases
- Stronger cases often need prescription medication like terbinafine
4. Be cautious with DIY ingredients
- Vinegar: generally safe, mild effect
- Baking soda: can dry skin, not a cure
- Harsh mixtures: can irritate or damage skin
🚨 When to see a doctor
- Pain while walking
- Nail lifting or severe discoloration
- Diabetes or poor circulation (don’t self-treat aggressively)
🧾 Bottom line
Your nana’s trick can improve the look temporarily, mainly by softening and cleaning the nail—but it’s not a cure, especially if fungus is involved.
If you tell me exactly what the “trick” is (ingredients + steps), I can break down whether it’s safe, helpful, or something you should skip.
