1. (self) Manicure once per week to include gentle filing, tidying cuticles and massaging an oil into cuticles (e.g. I use a small amount of peach oil, but olive oil works. Even Vaseline/lipbalm helps). Trim any part of the nail that looks like it's going to break and gently file away jagged edges. Smooth nail contours are less likely to break/catch on things. Squoval or rounded shapes are good. Square means the edges can be vulnerable and pointy can be tricky to maintain and probably isn't possible on short nails anyway.
2. Use a strengthening base coat (on clean, dry nails only)
3. Nu Nale cream is supposed to be very good. I bought it, but haven't used it yet
4. Use gentler nail polish removers e.g acetone free, moisturising
5. Avoid acrylic/any fake nails. These will only weaken your nails
6. If you buff, only buff gently and infrequently
7. Moisturize your hands constantly. Especially if they feel dry or after washing your hands. Have a large bottle next to your desk and carry a small tube in your handbag when out and about
8. Avoid getting your hands dirty/wet unless absolutely necessary. This reduces the need to wash your hands
9. If you must do washing up etc, USE GLOVES!
10. Use a moisturizing/gentle handwash e.g. Dove. Many handwashes (esp those in public toilets) are very harsh
11. Once every few weeks exfoliate hands with a mixture of olive oil + salt or sugar and wash off. Massage cuticles and nails gently. Hands will feel super soft. Also works all over the body (except face)
12. Never use your nails as tools e.g. to open cans, peel/scratch things. Use a fork or a coin etc
13. Eat more protein and healthy fats
14. Eat more fruit and veg
