Hair: Like others here, I do the baking soda-in-water instead of shampoo, with a vinegar rinse. I follow that with organic conditioner on the ends, or sometimes with almond oil. I don't dye my hair and have few white hairs. I'm hoping that it will all turn silver eventually. For DD6, I use a few drops of almond oil rubbed in my hands and onto her hair about once a week.
The no-poo method took a few tries for me. I finally got it after going a week or so without washing my hair at all, then used the baking soda/water and then diluted vinegar rinse. My hair finally felt clean and soft. It had been getting very very dry, and very tangly, so that my hands would get stuck in it if I tried to run my hand through my hair. Co-washing alone didn't help. Neither did fancy expensive products suggested by friends (I'm looking at you, Kerastase bottle). So now, it's been about a month and a half, and I used a drop of shampoo on the crown of my head one time in that month. Otherwise, baking soda/water and vinegar, plus maybe conditioner. I LOVE my hair again.
DH cuts my hair, and his hair and our kids' hair. He's good with sharp instruments. Plus I hate making appointments and my favorite hairdresser is never ready for drop-ins.
Face:
I drink a LOT of water and I smile often. Also, I use Oil of Olay with sunscreen daily.
Makeup: I use a Revlon BB cream about half the week (workdays), but I use very little and this tube has lasted more than a year and is still going. I use eyeliner and brow liner, both of which last forever. Honestly, the brow liner is 11 years old. I sometimes use shadow--maybelline. I use an eyelash curler, which does get a new cushion about once a year (or I buy a new one). And lipliner and/or lipstick, which I replace maybe every 2-3 years. I like to look professional at work.
Cleanser: At night only on days I wear the BB cream, I use a drop of an Oil of Olay sensitive face wash, and the bottle lasts for a long long long time. I want to say 3-5 years. I use a good washcloth in the shower on days I shower to exfoliate.
Body:
No soap except for underarms and pelvic area. Cheap conditioner as shaving cream. Used to wax, got tired of making appointments. Tried laser hair removal, it hurt. It was free, actually, but I don't like the pain and am bad at making appointments. I exercise a few times/week. Not in terrific shape, but it'll do.
Fancy stuff:
I occasionally get Botox. Was recommended for migraines, and it works for those, but I don't deny that I get more than is necessary for the migraine treatment. This is free for me and I don't have to make an appointment (I've got a hookup), though, so cost-effective. Judge away.
