Just need to know what this can be?? A friend of mine, who is not my client, has been having L&P tip extensions for over 2 years. I saw her yesterday and she showed me her thumb nail. There are a lot white blisters at the side of her thumb which is spreading under her nail plate. She says her nail underneath her extensions is breaking away. Anyway the doctor has now prescribed a course of tablets for this but she still wants to keep her extensions. I said it could be that she is now allergic to the products and have suggested she have a break from extensions. What does this sound like!! I've never seen or heard of this before and she wants me to advise her!!!
