I know my hair has begun to grey since going Paleo (2 1/2 years now). Then again, I'm 45, so it's about time for it. I have no way of knowing if, perhaps, it's been slowed by my excellent Paleo diet (I only have a half a dozen strands of silver so far).
I WILL say that both my hair and my skin have improved markedly since I gave up soap, shampoo, conditioner, lotions, sunscreen, etc, etc. It's been astounding. So my Paleo lifestyle has definitely helped my look younger despite the grey, LOL!
My hair was just starting to develop a few greys when I started paleo. Seems like that has somewhat reversed now. THere are fewer of them or they seem less grey. But it's a bit hard for me to tell because my hair is light and so the greys did not stick out well anyway. Could be that my hair was right on the threshold of greying so maybe it was easier to alter that? (just guessing) -Eva
Well, if graying hair is a sign of aging, and aspects of the Paleo diet have a decelerating effect on aging, then theoretically graying could be delayed by following a Paleo lifestyle. I know that glycation has a lot to do with markers of aging in other areas (i.e. skin elasticity v.s. wrinkling), so I would suspect that natural graying would be linked to that and the usual damaging aspects of living life 'too fast' - inflammation, rapid cellular destruction, etc.
There are other reasons behind the graying of hair; however, many can still be attributed to inflammation - i.e. stress & shock.
A few years ago I fell down the stairs and broke my back. Shortly after my blonde hair fell out (not surprising really) and grew back a lovely silver colour. And now, after being Paleo since August, my hair is falling out again but the regrowth is DARK! Something strange is happening!
Since going Paleo 4 years ago, I've noticed markedly LESS grey hair. I thought the mirror (or my vanity) was fooling me, but I've had a few online convos with some others who have experienced similar. I'm 53 and no longer colour my hair (I was not that grey when I started). It's not that the grey has disappeared, it hasn't, it's just lessened considerably.
I also had some gray hair reversal. Gray at the bottom, brown at the root. Here's a post from evolutionary medicine forum that discusses it. It has to do with the peroxisomes in our hair roots - we bleach our own hair as we age.
