Lately, whenever I turn on the fan (not even the AC necessarily), a tangy smell like Elmer's School Glue or caulk comes out of the vents. The mechanics at Firestone don't recognize the smell.
Many salon workers face low wages, so tipping is their means of making ends meet. (And on that note, if you suspect your salon has poor conditions for its employees, report it to your local public advocate's office.) Tip 20% for a standard manicure, more if you feel your service was exceptional.
Pay attention to your nails and allow them to regrow and repair. Consider getting gel manicures only occasionally to decrease the risk of problems. When getting gel manicures, wear a broad-spectrum sunscreen on your hands to minimize damage caused by exposure to UV light during the curing process.
