No no, what I'm saying based off studies online is if in the rare case someone has a Vitamin D deficiency, and no genetic link to hairloss, and their hair is thin it can sometimes be due to the vitamin D deficiency if levels are low enough for long enough. I'm saying there is a chance it's due to my bad levels of vitamin D, but also could he genetic (some how, idfk)
So ideally, if it's due to vitamin D levels being low and hair not getting enough of what it needs, supplements may regorw hair if it isn't genetic. I'm asking how can I spot regrowth, and would it take like 3 or 6 months to notice any? Since if I'm genetically thinning, I'm in early stages so I have time to figure it out.
