So I had been using shampoo/conditioner every other day; on off-days I would just let water run through it in the shower.
That was working out fine enough, I suppose, but I had some recurring scalp dryness issues that I thought could be from all the chemicals and also the shampoo/conditioner I use is getting harder to find. Add to that the fact that my husband doesn't actually wash his hair at all anymore, and it looks perfectly fine and normal... I've now started experimenting with a new washing frequency.
At first I just tried to stop washing it until I couldn't stand it... and my hair got pretty greasy pretty fast.
But NOW I've realized that it might have had a lot to do with my still using conditioner. The shampoo was stripping my hair of oils/etc (at the same time as removing dirt), and the conditioner was adding back some of it, but that was starting me off with extra build-up. SO! I'm currently on day... 6? of no shampoo, and my hair's only just beginning to be kind-of unacceptable looking.
I'll wash it in the morning.
But for now, look at my awesome front-hair once it's been taken out of its french braid!
Doubt I'd often wear it out this way, though...
