Online I saw an article that was saying that baking soda can be damaging to the hair due to its high acidity. Will this be detrimental to my hair in the longterm use? Also On top of my head I noticed, not quite a bald spot, but it seems like a kind of spiral between about three points of hair groups so it is showing my scalp, is this normal when the hair is starting to section and it will show areas of the scalp kind of like balding but not actually balding, just showing more scalp then usual?
