I have recently qualified and booked to do my first lash lift and tint tomorrow on a paying client (I'm nervous). I hope that i can explain my query properly - when you place the lift product on the first lashes, once happy it is covered you start applying on the second lashes. Then you start the timer? I am concerned because by the time i have applied the product to the second lot lashes, the first lot may have already been on processing for a minute? Do you apply to the first eye and then start the timer, then apply to the second set and apply the timer? Take off and apply the setting in the same way? I think I am possibly confusing myself at the moment. Don't want to over process one eye more than the other.
