Is eyelash tinting any good and safe? - eyelash tinting safe

Hello
My friend is gettng her eyelashes tinted at a salon next month and will go with it and do well.
I am tempted because I'm blond and blond eyelashes, but I've heard it is not clear complexion (I thought it was like his design for the eye and uses reputable salons) and dropped something on the lashes!? is the contrast that makes them? i dont want that! It is also worth it? I do not dye the fullness and volume mascara that does nothing, but I can not be bothered with mascara on holiday!
I thank you all xx
