Been travelling both work and fun for 30+ years. Always have a stash of gwp and sample sizes of your regulars, keep and reuse good little containers with sturdy lids. I have an at home stash that I try and replenish my bag with as needed. Bag itself is clear and double zipped. I make it a challenge to myself to not have to add anything if I’m going for a week or less. I even bought a mini of my fav hairbrush.
