eyebrow tattoo

You'll remove your makeup before getting eyebrow tattoos, right?

Then, do I need to take a picture of my usual eyebrow shape?

Or does the director take charge and adjust it to suit your face shape?

Or do I go with makeup on, show it, and then remove it?

My eyebrows are so sparse that both I and everyone around me are telling me to get them done, but since it's my first time, I don't know where to start.
