Why you’ll love it: A Paul Mitchell’s cult-fave reimagined as a zero-plastic shampoo bar. Tea tree, peppermint, and lavender deliver that signature tingle that refreshes your scalp with every wash.

How you’ll use it: Lather up, massage in, and rinse out. TSA-friendly design makes it easy to stash in a travel bag–and it lasts longer than liquid shampoo too.
