Are the latest beauty and wellness products worthy of a spot in your teensy carry-on? T+L Associate Editor Kathryn O’Shea-Evans shares her take.

Pros: For someone with the finest hair in creation, I had high hopes for this (translation: I hoped my hair would get considerably high-er). And—surprise—it did! A few spritzes at my roots gave me news anchor-volume.

Cons: Unfortunately the bottle is too big to make it past the TSA, so won't work if you carry on.

Verdict: Packable—but only if you’re checking your bag.
