Why is My French Manicure Yellowing? Causes & Solutions

Question
Hi!
I have been getting my nails done at the same salon for several years.  I have
natural nails,, and always get a French manicure.  Recently my manicure will
yellow after just a couple of days.  Could you tell me what could cause this?  
My manicurist said it was blow drying my hair too soon after the manicure...I
have never had this problem before, so I feel like there must be a different
answer.  Soa?  Hair products?  Skin products?  Top coat?
HELP!  and thank you for your time!!!

Answer
Hi Mary, you and your technician need to go over everything that was done. Anything is possible when it comes to chemicals. Has she started using a different top coat, have you started using a different lotion? Are you a smoker, did her product get contaminated? I'm figuring this is a new product problem. Do things differently next time visit. Ask your technician if its in the product or on the product. It could also be from Fluorescent Lighting as well!

If none of this works let me know.

Thanks!
