go to a local beauty salon that does nails and ask them to take a look at them and see if they think you should check with a doctor. they should be able to tell you if its a ';nail fungus'; or not.Nails problem?
The chemicals may have something to do with it. But, it maybe a nail fungus. If I were you, I would google ';nail fungus'; and see what pops up. Look at photos and see if they look similar to what your mom's nails look like.
Tell your mother to wear plastic gloves when she is cleaning. Get her some vitamins for nails, take her to get a professional manicure and last , take her to the doctor to get it checked out to be on the safe side.
