I have had a lady for nearly a yr now that came to me with eggshell nails, she specifically wanted gel overlays so thats what I gave her.
Unfortunately she came back a week later and they had all come off, I`m sure it wasn`t my prep as there was bits and pieces of gel on them, it looked really strange.
I wasn`t creative trained at the time and although I did L&P, I avoided doing them like the plague......She was eager to try something else so I used Backscratchers extreme.
She still has the same and during that time her nails began to take a nice shape and we`ve not had any more trouble with them, I only wish now I`d taken a before and after pic
