I finally got around to trying a baking soda wash with a vinegar rinse for my hair, as I said I would at the start of the month.
Most places I read about it said to use 1 tablespoon of baking soda in warm water, although others said to make a paste of it. I used probably a half tablespoon to try things out as some people found the full amount made their hair really dry. With hair as long as mine I tend toward the cautious side of things.
The mix is applied to the scalp, not the length of the hair. Overall I think I used too little, but I could definitely tell when the oils by the scalp started loosening up and moving. There was a definite change to the feel of my hair as I scrubbed it. Can’t say lathered it, as obviously there’s no lather with baking soda.
The vinegar rinse was made in the same way, one tablespoon of vinegar to one cup of warm water. That was applied to the length more so than the scalp.
First try, I’m not ecstatic. I’ll try using a bit more baking soda next time and maybe a bit less water and see if that helps. The hair near the scalp was left just a bit too oily.
