I have brittle nails that peel and flake how can I prevent this and make them strong?

This is caused by dry nails that fragment into layers and lift away from the nail bed. Brittle nails split and snap easily too, usually straight across or below the free edge or tip of the nail.  The problem is usually worse in the winter and in drier climates.  Brittle nails need to have flexibility restored by replenishing the nails' natural lipids with cuticle oil or cream.  Try Sally Hansen Diamond Nail + Cuticle Oil.

Sally Hansen Miracle Cure works wonders for severe peeling nails, filling in cracks to instantly strengthen and reinforce your nails.

There are many things which can trigger dehydration of the nails including frequent immersion in water or solvents such as soap or detergents, a lot of contact with soil and repeated use of nail polish removers. Try using Sally Hansen Acetone Free or Moisturising Nail Polish Removers to help prevent this.
