I have been wearing nail enhancements since the beginning of the year, but after having took them off a few weeks ago my nails are bright yellow. It happened before when i took them off for about week in the summer. i thought it was with smoking but i have stopped since i found i was pregnant in August. One of the other nail techs i work with said it was caused with the products. I was just wondering if anyone has had this and what it is? Honestly it looks like i have smoked about 100 hundred fags a day!!
