Hi guys, please can you help me out. My client has asked if she needs to give her nails a break from shellac. i dont yet offer this service so i dont know the ins and outs of the product. She is concerned that her nails will be weak underneath. Also is it okay say if they had a french finish in shellac that i could paint over the top of if using a normal nail polish...she wants to change the colour when she goes out in the evening..... if this is okay what would you do to remove the polish to revert back to the french tip. Sorry about the questions!!!!!!
