I only really save the toothbrush and mini toothpaste for use - they are great for a 1-2 day trip overseas when every inch of space counts in my carry-on bag.
My GF despairs at what toiletries I take (or more accurately I don't) when I travel. Toothpaste, toothbrush and deodorant...that's it for me. Even the deodorant is one of those mini ones you can buy in Boots so to keep uder the 100ml limit. Shower gel is simply whatever the hotel provides...
The GF can't seem to travel without taking between 15-20 items of shampoo, conditioner, numerous lotions and skin care products, perfumes, body sprays, deodarant, make-up etc etc
I always tell her she looks lovely whether she uses these products or not....but she can't seem to go away without decanting he whole bathroom cupboard first
