Most of us, I'm sure, with the 3-1-1 rules for carry-on, buy travel/sample size toiletries to at least get us started.
I have to admit I've never looked for these items in Europe.
Have people been able to find travel size items such as toothpaste, deodorant, sinkwashing liquid, shampoo, etc over there? If so, what did you find and where.
I'll start. For shaving, I've switched to shaving oil and the best stuff I've found is made in England by a company called Somerset. They make it for both men and women. If used correctly...and that means following the directions not what you think you should do....a little 12 ml bottle (about 0.4 oz) can last up to 90 shaves. And you get a pretty close shave.
Of course, now we have the shaving "sheets" (50 in a pack) that don't have to go in the 3-1-1 bag. They're not bad. I find I need 2-3 sheets per shave. I use the ones made by Travelon.
