Since I've got a living testimonial to no 'poo in my own house (two if you count Miss F), how could I not try it? But my hair's always been really greasy. When I was working, I washed every.single.day. If I didn't, I worried about how greasy my hair was, whether it actually was or not. Now that I (mostly) stay at home, I could stretch that to washing every other day. But when I worked out, which I do four days a week, I absolutely had to wash my hair.
The last time I washed my hair with commercial shampoo was Monday morning. On Tuesday, I washed after my workout with hot water only. I was pretty greasy feeling. It didn't look terrible, but I itched pretty badly. Wednesday, I washed with a mixture of 1 tablespoon of baking soda in one cup of water. I put it in a squeeze bottle (below) to make it easier to apply.
And I felt clean! Just like if I washed with shampoo. On Thursday, I washed with only water after working out. It didn't feel as clean as Wednesday, but I was able to go out in public without worrying about what people thought. Friday and Saturday went the same way - I washed with baking soda Friday, and on Saturday, you couldn't even tell it hadn't been washed when it was up in a ponytail.
One of these two pictures is me having washed with shampoo, and one is having washed with the baking soda mixture.
