Yes I had this also clients saying yes I want a certain shellac colour I did not have. Only to find when I got it In they didn't want that colour anymore!!!!Clients are the very worst for reading about something and saying 'you should get xyz in, it'd do really well'. Get the stuff in, and they don't bother to get it done.
I did ok with myscara, but we marketed it hard. Lash extensions were a flop, I can't even give my body treatment stuff away, and only about two clients had crystal toes.
