I wonder if I have cider vinegar or if I need to stop at the store tomorrow.

Any vinegar will work, but cider vinegar is the least ... startling when you're pouring it over your head.

Unfiltered apple cider? Because it is that or balsamic (I also have apricot balsamic) vinegar. I have no plainish vinegars.

I can't wait to try this.

But in the morning. Because I am going to try and go to bed and sleep now.

Jen, make sure whatever you're washing & conditioning with has no silicones.

It really depends on the texture and thickness of your hair. If your hair is thin, skipping washing it for a couple of days will make it look flat and stringy and gross.

Jen, you're probably not going to like this answer, but if you can go several days without washing your hair, let it get all gross and then after you start shampooing again, go to an every other day schedule, it works great. I did that a couple of years ago and it's worked great. I used to wash my hair every morning, but now I need to wash it only every other day. Unless I've been really sweaty.

I'm guessing you have fairly thick hair, and/or a lot of body, though?

I wash my hair once a week (in between I wet it and run conditioner through it once) and it's great. It's at its best on the second day after washing. The fun thing is after four days untouched it will basically stick in any position you pull it into. My co-workers treat it like a toy. "Is your hair dirty enough today to do the THING?"

make sure whatever you're washing & conditioning with has no silicones.

Yeah, and this is really important if you have long hair.

Also, I really sing the praises of dry shampoo. Bumble & Bumble makes a great one. It comes in different colors, and when I have to go out but my hair is a dirty greasy mess, I spray some B&B powder in there and smoosh it around, and voila! Instant illusion of cleanliness.

OK, no silicones. Off to read labels in my bathroom....

Jen, make sure whatever you're washing & conditioning with has no silicones.

thinks, "but it's just vinegar"

thinks again, and for real this time

I'm not "Jen" here. Not me.

Though it does lead me to realize that I have a gel that has "encapsulated silicone" and now that I read that, it seems bad. But it makes my hair not!stupid a lot of the time. I only use a dab though because I fear the lubed look.

I've used up all my sanity chits tonight I think. (eta: Now I am stressing that chit is a not nice word. Natter has changed me.)

I've combed talcum powder into my greasy hair many a time. Works pretty well.

I've stopped shampooing my head, and it's working out pretty well, not that my hair extrapolates that well around here. My no-cone was made simple by buying conditioner at Lush.
