When I travel, I just bring my LI and a hard hold gel. I use the LI for my co-wash. Might bring some more stuff if I was traveling for a special occasion but for a road trip I wouldn't stress it.. just too much of a hassle to carry around a lot of stuff for a short trip! Travel size bottles work well. Also, if you're going to stay at a hotel that has a hair dryer, you could bring a sock diffuser--way easier to carry than the bulky bowl diffuser.

Wish my hair was longer and fuller but it breaks off like crazy!
