Transcript

Mercury affects adults too. Hair loss, memory loss, slurred speech. Here’s a case report of a guy who ate tuna every day—became so crazy he was thrown in a psych ward. Couldn’t even remember his name.
It’s not always this dramatic though. Eating fish gives people sub-clinical neurobehavioral abnormalities, meaning you feel fine, you look fine, but if you’re actually put to the test, the performance of those who eat fish is significantly worse on a bunch of tests, like finger tapping speed—like how fast you can do this. But if go up against your fish eating friends and win bets seeing who can tap faster, I get a cut.

    Im just curious. You eat a healthy plant based diet (vegan) i assume, and usually the people that do have great hair health but ou seem to be balding. Is this a genetic thing or maybe exposure to something in your past?

    Dr. can olive oil using on scalp prevent DHT ? if yes, can it work so actively . Actually as you know revivogen a natural DHT inhabitor product which has omega3( i believe its derived from either flax seeds, olive oil or fish) plus it has alcohol which I think make it quite active along with zinc. revivogen is quite thin actually. it really works , I’ve found it incredible product but its costlier to me that is why I also bought hairmax comb also which is a one time investment but I believe I still miss revivogen.
    I want something topical, so I was searching what aleternative can be of revivogen, last week I used extra virgin olive in my hair at bedtime , trust me any kind of itching/ tigling which specially occurs after hairmax went away, i washed hair in the morning they were shiny like they had a life, though revivogen also does same work. I am just wondering can it really helpful using olive oil into scalp to stop DHT ?
