I currently do nails and have been offering my clients shellac for over 12 months. I dont have any problems with it and rave about it to everyone including my sister. I have been telling her for a while to get it done (I would do it myself but she lives in Spain) she found a nail tech in her area and had acrylics done by her first but due to sheer amount of lifting after a couple of days she decided to have them removed and had shellac applied instead. I did stress to her that her nails wouldn't be great at the moment due to the extensions. However she had it done and within 2 days they had all lifted. Her friend also had them done and 3 nails peeled completely off the same day. She however hadn't had anything previous on her nails. I know its not a CND lamp that is being used so for this reason is this why they are not staying on? I have sent her solar oil to look after them and emailed an aftercare sheet but feel gutted that this is happening when I convinced her to have it done in the first place. Is there any other reason why it is not lasting on them at all. Thank you
