(Actually, this works really well for travel as a whole, as it lasts a long time and is a whole lot lighter.)

Solid products also eliminate a lot of packaging waste, of course--and no, I don't work for Lush! (and I know some of y'all consider them to be, um, lowbrow, but hey, the stuff does the job for me.)

Or, just use plastic grocery bags to wrap up anything in your checked baggage that could leak...

I have traveled with small bottles of shampoo in my checked luggage for around 30 years now and never had a problem. This is not difficult. I've never taken shampoo or things like that in my carryon.

I just put shampoo in a small 2 oz travel size bottle (or buy those kind, or refill them when I save them from hotels), make sure the cap is screwed on tightly, and put it inside a ziplock baggie with perhaps a small bottle of hand lotion, etc. I may have a couple of those small baggies of things (one for hair stuff, one for deodorant and razor), and I throw them in a plastic grocery bag and put that on top. Sometimes I just put a small bottle directly into zipper cosmetic bag or something, with a few things, those can be bought lined with plastic.

I've never had one leak yet, even within my plastic bags. You'll never convince me to use solid shampoo -- I used to work for a large cosmetic and toiletries company and know what's in that stuff and I prefer the formulations of a liquid.

Well, Christine, by all means TELL US what is in it LOL! otherwise it is like the headline on a "National Enquirer"...

"Cosmetics SHOCKER: Ingredients in Solid Shampoo Can End Your Days!"

Well, Dukey, all the gory details are right there on the website, as Lush lists all their ingredients. I'm not sure which one(s) are the culprit. My hair hasn't fallen out yet!

Oh, and, of course, these would also be good for those who want to do all carry on for those flights where that's permitted, as they're non-gel.

Be sure the bottles of liquid are not full to the top. Since the baggage compartment isn't fully pressurized any liquid expands - and if the bottle is full it can either burst or liquid can ooze out the top.

Besides of course putting them inside a truly waterproof toiletries bag.

Also, always squeeze the bottle you intend to put liquid into before you seal it for flying. It allows for expansion during the flight. Old tip from a pilot friend of mine.

I love Lush solid shampoos. I use the Shiney ones..they come in their own little tins too.
My kids take them on their trips also..it is good on your skin too if you forget the soap
I also like Charles Worthington shampoo so that goes into a little travel bottle that goes into a ziplock bag..

Christina, these are the ingredients to one of the Lush shampoo bars...

I've never had problems with shampoo leaking either, but a friend just gave me some solid shampoo bars from a Lush (or similar)shop in Montreal and I love them. Nothing weird in them.

I've used Lush Gentil Lentil shampoo bar for ages , it really leaves your hair shiny and there's no need for conditioner , unless your hair is damaged to begin with. If I run out before I can find more, then I switch to Burt's Bee's Rosemary Mint bar.

Beleive me ziplocks are not failsafe when a bottle breaks or leaks

I like the concept of the solid bars, in fact, when I cut my hair really short a couple of months ago - I brought one in the little Lush tin with me to Italy. I was changing hotels nearly every night, though and found that the bar got completely stuck and smushed in the tin, because it never had a chance to dry out. Anyone have any ideas how to combat this?

Solid shampoos have been around for ages. Years ago, I used a Redken strawberry scented shampoo bar. I didn't like it that much. I will pass by a Lush shop tomorrow, will take a look at their shampoos (normally, I HATe going into the Lush stores, I think they reek, they smell like 1969 to me). I'm curious to see how well the shampoo bars are smelling.
I don't usually take shampoo with me when I fly...I like trying out different products at my destination.

Oops, selling not smelling!

Body Shops smell more like 1969 to me than Lush does.

I love that Lush smell! I was in Frankfurt a couple of weeks ago and just stood there for a few minutes trying to locate the shop. Finally found it on the second floor of a 'mall' nearby. I've found the two shops in Venice the same way - got a whiff and tracked them down.

Last year I spent a month in Rome and bought a ginger body cream at the Lush at Campo dei Fiori.At that point,we didn't have Lush in the U.S.(I think)
Now whenever I use that ginger body cream,I'm back in Rome!

One more time for nytraveler and any others who may still be confused about baggage compartments and pressurization on airliners. The baggage compartment is pressurized to exactly the same level (and approximately the same temperature) as the passenger compartment - generally the equivalent of 6,000 to 7,000 ft above sea level during the cruise phase of the flight. Anything that leaks in your checked baggage due to the decrease in pressure would also have leaked in a carryon.
