hello. i have a client who i do opi axxium gel nails for. sometimes they stay on others they dont and we cant find any logical reason for it. anyway she has also tried bio sculpture gel colour with slightly more luck. the last time she had them done they placed a small dot of glue in the middle of each nail. why would they do that? is it a bio sculpture thing or something that they have done themselves. my client asked why she did it and didnt really catch the answer . only that it was somethiing to do with when it is removed. i stumped. anyone know?
