I've read here and on other women's packing sites about bar shampoo and conditioner from Lush. I thought this sounded interesting, so I bought some last week to try out. I love it! A couple of swipes of the bar across my wet hair, and I'm all sudsed up. The conditioner works equally well, my hair feels soft,and scalp irritation is less than with my normal expensive shampoo. Lush makes it in little round shapes, and they sell lightweight carry tins that fit just right. Each tin+bar weighs less than 2 oz. Each bar lasts 60-80 washes, they say, so I think I'll use about half of it now, and pack the rest for my six-week trip this summer to make it even lighter. (BTW - I'm not staying in any hotels.)
The reason I'm interested is to reduce the amount of water weight I'm carrying in my 3-1-1 bag and overall in my carry-on luggage. Yes, I have often left wet toiletries home and purchased them in Europe. I really enjoy browsing supermarkets and pharmacies wherever I travel. But the often-overlooked problem is that once you buy that stuff, you are adding that weight to your carefully-packed-and-weighed bag for the rest of your trip. Sure, ditch it at your last stop, but now you've hauled it up and down subway stairs, and in and out of every subsequent hotel and mode of transportation. I'd much rather carry wine than shampoo!
With the encouragement of the Lush success, I looked at the rest of my wet stuff. Body lotion, sunscreen, and antiperspirant come in roll-on versions; mosquito repellent and hand sanitizer can be found as individual wipes; Lush body soap also fits a little round tin; even toothpaste can be bought in powdered form. I'm not carrying liquid makeup, just a 50-ml tinted moisturizer; that's still in my 3-1-1. That and possibly a mini bottle of mouthwash should be about the only liquids I'm taking. I haven't finished assembling and weighing these items, but I think I'll probably save over a pound of liquid weight.
Has anyone else tried this, and what were your results? Any tips on other items that fit the non-liquid/non-gel category?
