Here's what I use right now, but there are MANY MANY recipies out there, so if this isn't your cup of tea, keep searching
Deoderant: Mix together 1 Tablespoon each olive oil, cornstarch, and baking soda. That's it! Sometimes I add 1 part Shea Butter to help with any irritation and a drop or 2 of essential oils are always lovely. I put it in an airtight container and simply dip my fingers in and rub on. Whatevers left on my hand makes a great lotion!
Air/Fabric Freshener: To 2 Cups of Hot water add 2 Tablespoons Baking Soda. Mix thoroughly until dissolved. Add 2 Tablespoons Lemon Juice. Ta da!! Pour into a small spary bottle and let the freshening begin! (Essential oils here are great too!)
Conditioner: Using a vinegar rinse after you shampoo is a great way to seal the moisture into your hair. Mix 1 Tablespoon Apple Cider Vinegar into 1 Cup of warm water and pour over your luscious locks. (If you need more just add 2 TB to 2 cups and so on...) You're hair will not smell like vinegar once it's dried... promise. As far as a creamy-full-of-vitamins-makes-my-hair-shiny-and-happy conditioner any of the following are marvelous: Avacado, mayo, olive oil (My fav), egg yolk, or tea tree oil. Mash up whatever you have, goop it into your hair, wrap it up in a warm towel (just use your clothes dryer) and watch your fav TV show. Rinse THOROUGHLY and Voila!
Body Scrub: Take an old dried spice container (like from Cinnamon or Oregano), rinse it out well, let it dry and fill it up with... drum roll please.... Baking Soda!! (sometimes I cut it half and half with sea salt) Regular H20 is usually all I need to feel clean, that and a washcloth for some exfoliation. But for those uber icky days or when I want to glow (about every 2 weeks or so for me), get wet and start sprinkling! Scrub until you feel great then rinse well. If you want an extra treat, follow up by rubbing half a sliced lemon (or orange or grapefruit) over your skin. You'll smell great and litterally radiate with a youthful glow :) Great for dry feet, hands, elbow and knees too (also great for removing that "spray on tan" mistake you made...lol!) The baking soda can be a little drying (especially during the winter months)but shea butter or any leftover homemade deoderant is a great remedy.
Fabric softener: Just plain white vinegar in the fabric softer dispenser of my washing machine. Usually about 1-2 cups will do the trick. It works wonders, helps remove odors, and is completely eco-friendly. Again, a couple drops of essential oils will have everyone smelling each other!
Toothpaste: See Body scrub above I just use a smaller shaker container (filled only with bakingsoda) and store it in the medicine cabinet. Sometimes I also rinse with a bit of diluted Hydrogen Peroxide beforehand for extra whitening and to help remove any extra gunkiness between my teeth. Just follow the directions on the back of the Peroxide for the proper ratio.
I'll have to look into bar soap without cooking, but I'll find you something
