So, I took the plunge a couple of weeks ago and went no 'poo. I've tried it before but it was AWFUL. My hair ended up stringy and dry at the ends, miserably greasy at the roots. I did way more research this time around and realized that part of my problem is hard water (can't do much about that in our rental) and part of it was that I was trying to do no 'poo the same way I used shampoo--that is, washing my hair too frequently.
Well, this time around I've only washed my hair 3 times in two weeks (plus, once with a homemade dry shampoo made of arrowroot powder) and it's finally working! My hair got that slippery feeling when I washed it last night, rather than still feeling a bit dirty. The greasiness is totally gone and my hair looks shiny and healthy, feels soft and isn't super tangly.
In the last year I've started having to change my shampoo each time I needed a new bottle because while things would start off really well, by the end of the bottle my hair would be getting greasy really fast. I tried a huge variety of shampoos too, from cheapest to a really expensive (supposedly) earth-friendly one. So I decided to give this another try, since shampoo clearly was not doing me any favors.
My husband told me I'm strange, but I might try to turn him into a convert once we start seeing long-term results.
Baking soda and vinegar for the win!
