For how long should we take Nioxin?
The vitamins?
I plan to always take them, unless for some reason my body is able to be extremely healthy on its own. I don't see that happening since, I'll get older every year and my diet will stay pretty much the same. - I eat healthy foods but I'm not a fanatic about it and I believe in supplements.
If taking the vitamins for hair only, I still think they should be taken indefinately. Whatever is causing thin or thinning hair will most likely still be there unless it is from stress or a health issue that resolves itself and does not return.
