Pssssst Instant Spray Shampoo helps remove oiliness when you don't have time to wash your hair (or don't want to). I've never tried it but it sounds pretty interesting.

The freebies are on a first-come, first-serve basis, so it's unclear when the samples will run out. The samples take 6-8 weeks to arrive.

Thanks, Frugal Freebies!
