Well, I bit the bullet today and tried washing my hair without shampoo. I have been reading about using baking soda and vinegar as shampoo and rinse, and thought I would give it a try. I have pretty long hair, down nearly to my waist, and it tends to be fairly dry and frizzes on top where my grey hairs play havoc, but also gets a little greasy at the scalp if not washed regularly. I used about 3 Tbs in a mug of hot water at first, but since I had not washed it in two days it still felt a little dirty at the scalp so I took a few Tbs in my hand and applied it directly to that area. After rinsing, I have to say my hair felt the same as after a good shampoo, so stage one seemed to be a success. I was pretty skeptical about the vinegar rinse. My hair is very picky for conditioners, and anything less than Pantene leaves my hair un-brushable. I used about 1/4 cup vinegar in a mug with hot water, and poured it over my head rubbing it in as I did so. Immediately my hair felt smooth, and that feeling stayed after rinsing with water!
After I was done with my shower and dressed, the true test came-the brush. I started to brush my hair and it ran through as if I had been using salon conditioner! Much easier than with even Pantene!
I am sold. I will see what it looks like dry, and give it the test of time, but so far I really am happy. The good news is the baking soda comes in cardboard with no plastic, and while I used vinegar from a plastic jug (left over from summer) it is available in glass jars with only a plastic lid. If I can figure a way to get the rest of my family to join me, we can nix all those plastic bottles of shampoo and conditioner!
I will be looking at making herbal vinegar for my hair, I bet many herbs and spices would smell really good in a hair rinse, such as lavender, citrus, and vanilla.
