Another 'rule' breaker here. I wear my hair, clothes, jewelry, whatever that I like no matter what others say.

I've used vinegar rinses for a few decades and my hair loves them. And it does add some shine. I also us a dab of Ojon Restorative for shine and to control flyawayss.
I've never tried a baking soda rinse but will do that sometime.
