So i have don't a few full sets and few sculptured so far and an overlay on myself. It seems like whenever i do tips or sculptured nails they always break. All my clients break their nails. i don't know if its me or them. I can only assume its me. I try to pay extra attention to the apex so i build in the stress area but it doesn't seem to help. I don't know where i am going wrong. or if its even me. My nails have not broken once since i've done them. My sisters have actually grown out to a point where they are now overlays and she isn't having problems anymore either. What am i doing wrong? Please help me.
