Among the multitude of remedies for Grey hair listed on this thread, I have not seen onions mentioned. Onions work for me. Now in my late sixties, with barely a Grey hair, I average one small, raw, yellow onion a day, either in salads or otherwise. With a life style subject to constant changes, there are times, where my nutrition is not always guaranteed. One month with very few or next to no onions, will show up on my hair similar to tree rings - my normal colour, a whitish section, then normal colour, or another whitish section, depending on nutritional circumstances. This is my experience only, and simply and strictly anecdotal. I don't know how onions prevent or even reverse greying hair, all I know, it works for me. Onions, a household staple, inexpensive to obtain, may be the answer for those where other recipes don't work. Simply mix in salads, mix with mayonnaise, or what have you. Warning: Onions being a blood thinner, check with your physician if you are taking any blood thinning medications already. Do not exceed onion intake to more than a medium size yellow onion per day. Women may start to menstruate, even if beyond menopause.
