are your nails very hard? or extra soft? there are creams that are supposed to help chipping nails. one is made by denco products, i think everyone that makes nail polish has creams for cuticles and nails. you could try taking vitamin b that has all the b vitamins in it. biotin is a good one for nails and hair. but in the multiple b vitamins it is usually included. for a while keep your nails short. try getting a manicure or give yourself a manicure every 2 weeks. wear rubber gloves when you hands have to be in water or detergents. the manicures will help because once you start working with your nails and this might sound dumb but they flourish. i was a nail biter for 19 years and when i went to cosmetology school and we started working on manicures i stopped biting and my nails actually took to the pampering. gotta do it on a regular basis though. hope this helped you.
