Common Causes and Cures
Yellowing of nails on the fingers or toes often have different causes.
Fingernails stay healthiest when they are not covered with polishes, artificial nails, and glues for too long. Exposure to air and lots of water are what keep nails healthiest, and frequent application of nail conditioner or simple hand cream help as well.
This doesn’t mean not being able to wear nail polish all the time. It does mean changing it frequently, and also giving nails the occasional day or two to “rest” once in a while. Washing nail polish remover off well and immediately is an important first step after removing old polish, as well. Acetone remover is more drying, so even if you don’t use artificial nails or tips, it’s wise to stay away from remover with acetone in it.
When nail polish (or artificial nails) has been left on for more than two or three days, when it is removed the nails will appear dramatically drier and less naturally “pink”. The healthier color starts to return after that first good washing-off of the remover, but it can take a little while if the nails that have been covered with old polish for too long.
Although it isn’t necessary to NEVER immediately polish nails after removing old polish, giving nails that “rest” between polishings is the best practice. That can be accomplished easily and effortlessly by simply doing something like removing polish in early evening but not putting on a new coat until bedtime; or removing polish before bedtime and applying new polish the next day. When nails begins to appear just slightly less pink and healthy than they ordinarily do, it’s a good idea to leave polish off for two or three days; and just go with buffed and conditioned nails for a little while.
