Do you or your daughter have trouble with inflamed ear lobes when you wear ear-rings that aren’t gold or silver? Well a friend of mine who makes jewelry told me a trick for people who can only wear gold, silver or platinum ear-rings. Put clear nail polish over the post of your less expensive ear-rings. This will lessen the chance of your ear lobes having an allergic reaction to the cheaper metals. I had this problem myself and this solution worked. You have to reapply the clear polish after wearing the ear-rings after about three times. Also try plastic backings.
Another tip my friend gave me- The salt on your fingers can leave a brown color on the backs of your silver ear-rings. To get rid of it clean backings with toothpaste, but not the gel kind.
