If you're a male and you had real candida overgrowth then I'm sorry to say but in my experience you probably won't see any real significant regrowth of hair.
You may regain some fullness, yes, but if you developed male pattern baldness during the candida period, as I did, then basically your body went into shock and aged rapidly during that period. This is what happened to me. I basically aged a decade in a few years. After I beat the candida the first time, my hairline improved, but it never came back to what it was and I still have the rear bald spot that I didn't pre-candida.
