I've got a client coming into my salon tomorrow and she wants a facial, eyebrow and eyelash tint and an eyebrow shape. I'm not sure which order to do them in. Can anyone tell me what they think please.

What I would do is first do the facial then cleanse the brow and lash area apply the tint then clean and do the wax

it's eyebrow plucking i'm doing

I agree with Klassy Klaws.Although, its irrelevant whether you are waxing or plucking , you will still need to tint before shaping.
