I make lip balm/moisturizer with shortening and honey. This is also a good base for herbal salves (honey optional).
I don't dye my hair anymore, but when I did, it was with dye I made from black walnut hulls.
Dry hands: oats. Just steep a tablespoon or so of rolled oats in hot water for ten minutes and rub in the juice. Instant cure, lasts for days.
Hairstyling: frizzies can be tamed with the above oat juice, or actual styling/hold can be achieved if you use flaxseed, not oats. Use a much smaller amount for one time use, or store the mixture in the fridge for a couple of weeks if you style daily. I mostly style at Halloween and/or if I have to go to a funeral, so I use the one-time method.
Moisturizing salt scrub: two parts table salt, one part Epson salt, dash of olive oil. Can be scented with essential oils or dried chamomile flowers or rose petals.
Facial cleanser: homemade rosewater. Best stored in the refrigerator, which makes it all the more refreshing in summer. In winter, be sure to store it in a dark-colored or opaque bottle if you're not going to refrigerate.
