Clarifying hair: Baking soda... with starch?
I'd like to try clarifying my hair with baking soda. Going through the pantry, I found some baking "powder" (this is what they sell in Germany). It's basically Sodium Bicarbonate with starch. I'm unsure which starch it is, probably potato or cornstarch.
Does anyone know if this would be safe to use as a hair clarifying treatment? Starch and water alone basically make a glue, but I'm not certain if the bicarbonate in the mix will counteract it if it gets gunky.
