I have weak nails because they’re always in water so wearing gloves while washing, try keeping your hands out of the tub when having long baths etc.
You can also take hair, skin and nails supplements.

Weak nails often has to do with a nutrient deficiency, you may want to visit a naturopath when it’s an ongoing problem.

I bought the Sally Hansen nail hardener from Priceline and it did help

Use Revitanail you can get from a chemist,it works!

you can paint them and file them regularly

Revitanail Nail Strengthener actually works well.

I used to add a teaspoon of powdered gelitin to a glass of orange juice and drink this everyday. Now i have very hard nails.

I recommend blackmores hair skin and nails supplement, since taking this they have become a lot stronger I also use cuticle oil and Sally Hansen hard nails regularly.
