Nervous about first eyebrow waxing

I’ve never had any waxing or brow work done before. My biggest concern is that once they’re done, all the hairs that were waxed out will grow back darker and then I’ll have to keep waxing the rest of my life. I’ve plucked random hairs on my brows before and even though science says they don’t grow back darker, I swear the ones I’ve plucked come back darker.

Also, do your brows look crazy for like the first 24 hours after? What if they drop wax in your hair? How bad does it hurt? Tell me everything!

Oh, I plan on getting them tinted too so if you have advice about that, I’ll take it too!
