So for face masks, I would offer a variety for different skin types/needs. My favorite DIY mask is brown sugar, oatmeal and raw honey mixed together. Another good one is whipped eggs whites. This clay mask can be mixed with pretty much whatever you think is best for your skin, I personally just use apple cider vinegar. Sheet masks are great and you can find a lot of reasonably priced ones on amazon or even in drug stores these days.

For hair, I'd recommend a beer rinse! Sounds crazy, I know, but I assume there will be beer there anyway and it's just something nice to do for your hair. Cheap, room temp works best (don't waste the good stuff, drink it!), if there are any fallen soldiers (left over unfinished beer) from the night before you can just pour it through your hair after washing. it's great for removing product build up and leaves your hair seriously soft. And once you rinse the beer out and everything dries, you don't smell like alcohol.

That's all I could of off the top of my head, I hope you have a fun trip!

I have kind of a funny story.

A couple weeks ago I ordered this face mask off Amazon, but I got sent this $100+ electronic instead.

Quite the mix-up. Amazon gave me a refund and told me the converter is now mine with which to do what I want.

My dad said he might want to keep it for his old films. So, it's either going to be a free Christmas present for him or I'm going to sell it for a 100% profit.

This was the most random item I ever got because I didn't even order it.
