Here's the deal: Bumble is very kindly giving 5 ITG readers their own $500 gift certificate for treats and treatments at any Bb. network salon, plus the entire Hairdresser's Invisible Oil family of products. It's pretty great! Instead of just sending them away at random though, we're taking volunteers.

Tell us why you want to try these babies—why your hair NEEDS them, maybe—and we'll give 'em to the five readers whose answers we like best. Is it scientific? No, but it's a heck of a lot more fair (and fun) than some blind giveaway, right? So ladies and gents, start your Disqus engines! You have a week to respond...

*Update: The winners have been chosen! Thanks for participating. Wishing everyone a few more good hair days.
