Ooh hey, just found this thread.

I have long (hip length) hair, which I henna. I've been no-pooing for--gosh, about sixteen months now! Cool. (I was buying EXPENSIVE salon formulas before that, so I've saved a ton).
My routine is: Scritch and scrub under the shower for quite a while. Then dunk my hair in a chamomile tea brew (in a big Pyrex measuring jug, just because!) and swirl it around for maximum effect before tipping the tea over my head. Then I add about a tablespoon of ACV to the jug, half fill it with water and do the same swirl-tip-rinse routine. I have to rinse the ACV out, otherwise it makes my skin feel itchy; I know some people happily leave it on. Then, depending on my mental fortitude that day, I may or may not finish with a blast of cold water to seal the cuticle. (If not, I cheat and dip my braid in cold water afterwards).
In between washes, which are distressingly infrequent now I have a baby, I use a boar bristle brush to spread the sebum down the hair shaft. At least, in theory I do--my hair's been kinda gross lately, I've been so busy! I'm also one of those unfortunate mortals for whom henna does
not improve hair--my hair likes moisture, not protein. So after a henna I give my hair a moisture treatment. Last time's treatment, which worked quite nicely, was honey mixed with a tiny bit of very strong chamomile tea, and some milk powder mixed in. I slathered it on and left it for a bit while I cleaned the bathroom. Honey is good--I'd use it more often, but it's so expensive.
Things that haven't worked for me include aloe vera gel and jojoba oil. I used the latter for ages, fondly hoping it was helping, but it just made my hair feel crunchy and greasy without being moisturised. Works for lots of people, just not for me!
I'd like to try a rosemary brew sometime, we have a bush of the stuff in the garden. The trouble is, I'm never sure where red hair fits into the 'rosemary for dark, chamomile for blonde' scheme! My hair is naturally a sort of blondey brown, so that doesn't help; and my hennaed hair probably errs towards dark rather than light, but there's not much in it...
