I think you will find that your liquids will fit easily if you just reduce the size of the container. That being said I've never had an issue with toothpaste, liquid face lotion, conditioner and shampoo, etc. Gosh, I can't even recall what I used to take in liquid form, but it fit. Change the sizing. I've reduced my liquids over the years to just my toothpaste, mouthwash, eyedrops and an eye drop medicine. The rest are non-liquids. Experiment and you might find bar and shampoo conditioners you like. I didn't like Lush, but my daughter gave me some from another vendor...Suds (? I can look it up if interested). Before having a child, I had curly/wavy hair. I am not much of a female I guess as I have no idea what you refer to to maintain it that takes up so much room. LOL. Mine was wash, fingers through it once, and let dry. Or iron...as that was the day. So maybe just adapt for vacation? Get your hair styled for a natural style? Love your hair as it is. Just something to think about. It's only 6 weeks, but they say 6 weeks makes a habit. It could change your life!
I also don't understand what @horsewoofie is referring to about extra old lady things...but I'd like to know as it is making me very curious. I digressed a little. I have a red head's skin coloring even though my auburn hair disappeared in my 20's, so I've used suntan lotion and avoided direct sun for my entire life as 15 minutes in the sun and I was burned in the salty air. I use solid form sun tan lotion...like the solid deodorants. I've always used Oil of 'Delay' on my face, which has some, not a lot, SPF built in, and that's disregarded on trips where I use a lush facial item under my solid roll on moisturizer or suntan lotion. So here I know you can avoid filling up a bag with suntan lotion ( and deodorant, shampoo and conditioner)...just get bar or solid form.
I wasn't a make-up type of girl, but with mature years I do use Boom sticks for lipstick and a little glow to highlight my wise wrinkles sometimes. Again, no liquid. You can do this. Just relax.
I check my carryon bag so I don't have to deal with it in the airport, but I suspect those days are over for a while. LOL.
