Figure out how much actual product you need for your 1 week of travel and find the appropriate-sized refillable bottle and bring just enough for that 1 week. The amount one needs is rarely that entire 3 oz size drugstores sell in their travel section. Other items such as shaving foam can be replaced by switching to shaving oil or even conditioner in a pinch. A 1 oz bottle of shaving oil can last months. I also separate the actual liquids into the liquids bag and the non liquids into its own bag. My toiletries kit is extra-small because it is actually my non-liquids bag.
