15 tips for strong healthy nails:

1. **Keep nails clean and dry**: Regularly wash your hands and feet with mild soap and water, ensuring to dry them thoroughly afterward to prevent fungal infections.

2. **Moisturize**: Apply moisturizer to your nails and cuticles regularly to keep them hydrated and prevent them from becoming brittle.

3. **Trim nails properly**: Use sharp, clean nail clippers to trim your nails straight across and then round the tips slightly. Avoid cutting your nails too short, as this can increase the risk of ingrown nails.

4. **File nails gently**: Use a fine-grit nail file to shape your nails, filing them in one direction to prevent splitting and weakening.

5. **Protect nails**: Wear gloves when doing household chores, gardening, or using harsh chemicals to protect your nails from damage and drying out.

6. **Limit exposure to water**: Prolonged exposure to water, especially hot water, can weaken nails. Wear gloves while washing dishes or cleaning to minimize water contact.

7. **Maintain a balanced diet**: Eat a nutritious diet rich in vitamins, minerals, and protein to support healthy nail growth. Include foods high in biotin, such as eggs, nuts, and whole grains.

8. **Stay hydrated**: Drink plenty of water throughout the day to keep your nails and cuticles hydrated from the inside out.

9. **Supplement if necessary**: Consider taking supplements containing biotin, collagen, or other nutrients known to promote nail health, but consult with a healthcare professional before starting any new supplements.

10. **Limit nail polish remover**: Avoid using nail polish remover containing harsh chemicals like acetone too frequently, as it can dry out and weaken nails. Opt for acetone-free formulas when possible.

11. **Give nails a break**: Take breaks from wearing nail polish and artificial nails to allow your natural nails to breathe and recover.

12. **Use protective base coat**: Apply a protective base coat before applying nail polish to prevent staining and damage to the nails.

13. **Avoid picking or biting nails**: Resist the urge to pick, bite, or peel your nails, as this can damage the nail bed and increase the risk of infection.

14. **Massage cuticles**: Gently massage your cuticles with moisturizing oils or creams to promote healthy nail growth and improve circulation to the nail bed.

15. **Protect nails during manicures**: Be gentle during manicures and pedicures, avoiding overly aggressive techniques or tools that can damage the nails or cuticles.

By incorporating these tips into your nail care routine, you can help promote strong and healthy nails. If you have specific concerns about your nail health, consult with a dermatologist or healthcare professional for personalized advice and treatment.
