That's just silly. I travel all the time. I NEVER take shampoo, or even toothpaste. You can always get those things in the gift shop of your hotel, and the shampoo's right there in your room.
I quit taking liquids in my luggage, checked or carry-on, after a toothpaste tube got crushed by something and squirted the crap all over the stuff in my carry-on.
Of course, I'm a guy, and don't need twelve bottles of various lotions and unguents to stay beautiful.
It's just not that big a deal.
My FRiend, that's what Zip-Loc bags are for.
Well, I'm also a guy who travels all the time on business. Two trips in the next ten days. I generally don't have time to stop for contact solution & toothpaste (shampoo I can get at the hotel) every time I land.
Incidentally, I can't recall ever having a problem with stuff squirting all over my luggage.
I don't think this is about explosives at all.
Worse.
