I currently mix 2-3tsp of baking soda with 8oz of water. Don't laugh; I mix it in the peri bottle I got from the hospital when I had Raiden. And I only use about 1/4 of the bottle when I wash my hair.
This took a lot of trial and error, and seems to have finally decided to work perfectly, after I cut nearly a foot of hair off my head. My long hair seemed to feel like there was build-up on it a lot, and my short hair doesn't at all. I don't know if my long hair was damaged or just not rinsing cleanly or what, but it felt yucky, and I'd still have to use shampoo every fourth shampoo or so to get rid of it.
Since getting the hair whacked off, I haven't used shampoo once. The way it gets dirty now is completely different than how it got dirty before. With shampoo, you're stripping away your body's natural oils and your scalp freaks out and overcompensates by making itself more oily. With baking soda, it just sort of removes the excess oil without stripping anything, and it feels like a cleaner oil. I can go 3-4 days without washing at this point, and even when it starts looking like it needs to be washed, it doesn't look gross, and it doesn't feel dirty when I run my hands through my hair. Just a totally different world.
About 2tbsp of apple cider vinegar (ACV) in about 8oz of water. Typically I slosh some ACV into a cup and hold the cup up to the shower head until it looks like about a cup or so. After washing and rinsing well with the baking soda, I pour the entire cup of water over my head, massage it in, and let it set until I'm ready to rinse it out. My hair is the softest it's ever been.
I have definitely learned to use a higher quality, more natural ACV. Braggs is good, though there was another natural, organic variety right next to it at the health food store for a dollar or two cheaper, so I got that instead. Before, I used Kroger brand cheap ACV, and it made my hair feel really oily. Also the smell isn't as strong, and goes away faster, with the higher quality ACV. Yes, the smell goes away when it dries. It kind of smells like, um, nothing.
This is a recent one. I tried making homemade flax seed hair gel (boil flax in water and then strain; I've seen varying amounts of flax/water suggested online). Hahaha, fail. Trying to "strain" this mixture of goo was absolutely ridiculous and looked totally inappropriate, dripping out the bottom of the strainer. I'll say it: I nicknamed it "flax jizz." I was able to salvage enough to put in a little bottle and it doesn't suck to use, but oh man, not a process worth repeating. I saw a suggestion somewhere online that said to put the flax in some old nylons and then boil, so you don't have the problem with straining, but we'll see.
My next try -- lemon hairspray -- worked much better. Cube one lemon, or orange, or half of each (something, somewhere said that the orange is better for dry hair) (I used a large lemon), and boil it in 2 cups of water until the amount is reduced by half; strain and pour into a spray bottle. This, I love. I probably ought to strain it a little more thoroughly, as a bit of pulp came through the wire mesh strainer, but I'm not bothered by it enough to do anything about it.
I've used this a few times now, both having sprayed it on when my hair was wet and letting it dry along with it, and spraying it on when dry, and it seems to work well either way. It's just enough to keep the flippy-outty part of my hair from falling flat, and helps it keep some of the wave, without feeling yucky later.
I use henna, instead of dye. Check out http://www.hennaforhair.com/ for all kinds of info. The color looks more natural (it stains each hair individually rather than dying it one certain shade, so there's still a natural color variance), it makes your hair stronger and softer, and it's an anti-fungal, which means anti-dandruff. I mix mine with tea (what kind depends on what mood I'm in, but it's been apple-chamomile the past few times), and you can get a different color shade depending on what you mix it with, as well. Turns out mixing it with chamomile is supposed to make it more golden. I wish I'd read that before I mixed it with chamomile and hoped it'd turn out a cooler red rather than warmer. Oh well, now I know.
You'll see some repeats here.
The same baking soda and water mixture I use on my hair. I squirt some on a wash rag, and wash my face. The end.
A 50/50 mixture of ACV and water. I keep a mixture in a tiny Gladware tub in my medicine cabinet, and dip in a corner of a wash rag then run it over my face.
Raw, unrefined coconut oil, with a few drops of Rose essential oil and Sweet Orange essential oil. Coconut oil is good for pretty much everything and is supposed to be a good anti-wrinkle product, too. Rose oil is good energy, sweet orange oil is supposed to be energizing, and mostly, I just like the combination of scents. I'll use a little of the mixture for lip gloss every now and then, too.
Another repeat: while I'm slathering the 50/50 ACV/water mixture over my face, I do the same for my underarms. The acidity in the ACV raises your pH so bacteria can't grow. No body odor. No chemicals giving me breast cancer. I still sweat (it's not an anti-perspirant), it's just not stinky.
Next up, I want to try making my own natural bug repellent from essential oils as seen here (at the bottom) and here. The little one and I can attract every chigger and mosquito within a 12 mile radius. My poor kid, he even had chigger bites on his scrotum recently. I can't imagine that would be pleasant.
I'm looking into some natural flea remedies today, too, as I don't like the idea of spraying my cats or carpet with chemicals and poisons that "should" be safe when they dry. So far I've found Diatomaceous Earth that I could sprinkle around the house, and a few more natural options to use in/on the pet, that I need to do a bit more looking on, but it's a good starting point.
