I was a cosmetologist and I also did some manicures. I had problems like this too when I wore the plastic gloves. I also have eczema and it could be that too. Her best bet would be to go to a dermatologist and also make a list of the products she uses and take that with her.Or better yet take the product containers with her. She may be ablet to continue the manicuring but maybe switch to different product to use on the customers. Hope this helps.
