      You should look into whether eating blackstrap molasses helps reverse graying hair. I tried it once, for a little while, and it seemed to help. Haven’t been able to get back into it. Don’t really know what to put blackstrap molasses on, lol.

    Thanks and happy holidays, doc!

    It seems that grey hair will get to us all at some point. I am always fascinated by people in advanced age who have very little grey hair.

  • @spoudaois says:

    What about spermadine and graying hair?

  • @KevsGuide says:

    What age is not premature. For Frey hair pls

    • @cat12-b7i says:

      Premature graying is defined before age 20 in Caucasians, but before age 30 in African-Americans. Age 25 has been suggested as a cutoff for India.

    Zinc deficiency can cause premature gray hair.

  • @DashingPartyCrasher says:

    Just turned 56 and still color my greys every two months or so. Thankful it’s just on the sides and a bit in back. Some people look great with grey, but I don’t like looking older, or even my age.
    It seems that I now have less grey after increasing my B complex to three times a day (I open and split up one capsule), and better managing my reaction to stress. That’s the main key! 🔑🧘‍♂️

  • @kurtzcol says:

    now if i only had enough hair to worry about

  • @RoughNeckDelta says:

    Anecdotally, B12, zinc, whole foods, and lots of anti-oxidants is not stopping my progression of greying

    • @AmroNaddy says:

      Your dietary choices may have significantly slowed down your graying – it’s impossible to know. Do you have any siblings who went gray before you for comparison?

  • @memofromessex says:

    Looks in a mirror, immediately takes B-12 tablets.

    Thank you!

  • @levi5073 says:

    My hair went grey very suddenly shortly after my GERD and IBD diagnosis. However, the pain stops me sleeping and eating properly which in turn causes chronic stress and anxiety. When I found a tolerable diet, the pain and thus stress reduced and my hair colour came back. It was very weird.

  • @VeganChiefWarrior says:

    I lost nearly my whole beard to stress, its mostly white baby hairs now lol aging backwards 😅 and yea the head hairs thinning and going grey 2, i am 30, but only in age not life experience so that sucks, i will be dying my hair and going hard on the rosemary oil, I guess it really is like 99 percent genetics, question is what causes genetics to weaken to the point of going bald, it’s not in my genetics my pop died with a full head of hair on both sides, so I better not go bald, it’s looking thin on top but maybe it’s just from going through bouts of severe anxiety and depression and becoming a dam hypochondriac after learning I have a habit of doing everything wrong according to science
