It's been awhile since I wrote an update on my hair-care regimen, so here it is...
Since January 2, I have been using a mixture of baking soda and water to wash my hair instead of regular shampoo.
In all, my hair is a bit more difficult to manage than it used to be - I have to be quite thorough when rinsing my hair of the baking soda rinse, or my hair will have a bit of a greasy-feeling film on it, and my hair is a bit more difficult to run a brush through than it was when I used conventional conditioners.
It has also been commented to me that may hair seems more 'dull' in colour than it used to, and others have described this look as being more 'natural'. This makes sense, since the more damaged your hair is by chemicals, the shinier it will be - just take a look at anyone who spends a lot of time in a chlorinated swimming pool.
My hair seems thicker than it used to, and looks better in less 'perfect' hairstyles, like 'messy' ponytails, than it used to. I can also go at least two days between washing my hair, while in the past my hair became noticeably greasy after only one day. It also takes quite a bit off my monthly grocery bill, which is really just all win.
So, for the foreseeable future, I will continue washing my hair with baking soda. Even though my husband thinks it's weird.
