Hi Anisa
Either you have a vitamin/mineral deficiency that is causing your nails to become weak or your nails are over exposed to water or cleaning detergents. Get a supplement that will promote healthy hair, skin and nails. Be sure to eat enough fruit and vegetables. You can also look for a nail strengthening gel (not nail varnish) that you can apply to the surface of your nails. If your hands are exposed to harsh detergents then get a pair of gloves that can protect them from chemical damage. I would also advise you get episone E ointment for your hands and nails
