Beneath is an approximation of this video’s audio content material. To see any graphs, charts, graphics, photographs, and quotes to which Dr. Greger could also be referring, watch the above video.

Intro: We’re kicking off a three-video sequence on hair loss. What causes it? And what can medication, dietary supplements, and meals do to assist stop or reverse it?  Watch the movies to seek out out. I do know I’m going to.

“Research present that by age 50, roughly half of women and men will expertise hair loss.” No, it’s not brought on by washing your hair an excessive amount of, or brushing your hair an excessive amount of––two of the various myths on the market. The vast majority of hair loss with age is genetic for each men and women, within the case of this examine. Primarily based on twin research, the heritability of baldness in males is 79 %, which means about 80 % of the variations in hair loss between males is genetically decided. However that also leaves some wiggle room.

Even when you’ve got an identical twins––an identical twin sisters on this case, with the identical DNA––one can have extra hair loss than the opposite, due to Elevated stress, elevated smoking, having extra youngsters, or having a historical past of hypertension or most cancers. For instance, try these two an identical twin brothers. Similar genes, however the twin on the proper reported extra stress in his life. On this pair, the an identical twin on the proper was a smoker and drank extra alcohol.

Smoking can contribute to the event of each female and male sample baldness as a result of the genotoxic compounds in cigarettes could harm the DNA in hair follicles, and trigger microvascular poisoning within the base of the follicle. Different poisonous brokers related to hair loss embrace mercury, as a result of it appears to pay attention about 250-fold in rising scalp hair. In truth, perhaps the explanation Shakespeare began dropping his hair was attributable to mercury poisoning from syphilis remedy. Fortunately, docs don’t give folks mercury anymore. As of late, because the CDC factors out, mercury primarily enters the physique via seafood consumption.

“Ladies of reproductive age often search remedy for what’s considered hormone-related hair loss particularly at menopause.” However, for instance, this lady got here in with hair loss, and blood assessments indicated elevated mercury ranges. And, no marvel, as she had a eating regimen excessive in tuna. However the excellent news is that her mercury ranges fell with elimination of dietary tuna. Inside two months, her hair began to return again, and after seven months sustaining a fish-free eating regimen, her hair fully regrew. So, docs ought to take into account screening for mercury toxicity after they see hair loss, since there’s one thing we will do about it. Instructing sufferers to cut back fish consumption and repeat blood assessments may supply reduction of signs, and uncover dietary habits which may be a supply of heavy metal-induced hair loss. Although admittedly, generally heavy metallic can result in an excessive amount of hair.

What about nutrient deficiencies as a reason for hair loss? After bariatric surgical procedure, probably the most frequent nutrient deficiency symptom is hair loss. However that’s as a result of they’ve had their anatomy rearranged to trigger malabsorption on goal. Generally, there’s little proof to recommend that vitamin and mineral supplementation advantages folks, except they’re truly poor.

For instance, we’ve identified for hundreds of years that scurvy, extreme vitamin C deficiency, could cause hair loss, however after you have sufficient vitamin C such that your gums aren’t bleeding, there’s no information correlating vitamin C ranges and hair loss after you have a sure baseline sufficiency of vitamin C.

It’s additionally a fantasy that dietary supplements containing zinc will enhance hair progress––except you could have zinc deficiency, like when you’re an alcoholic or one thing. However when you’ve got regular zinc ranges in your blood, taking extra zinc received’t assist, and actually can have detrimental unwanted side effects. It’s the identical factor with taking iron dietary supplements.

The commonest ingredient in top-selling hair loss merchandise is vitamin B7, also called biotin. Sure, biotin deficiency causes hair loss, however there are not any evidence-based information that supplementing biotin promotes hair progress. And extreme biotin deficiency in wholesome people consuming a standard eating regimen has by no means been reported. However when you eat uncooked egg whites, you’ll be able to purchase a biotin deficiency, since there are these compounds that connect to biotin and stop it from being absorbed. However aside from uncommon deficiency syndromes, it’s a fantasy that biotin dietary supplements enhance hair progress.

However hey, why not simply have the angle, ‘‘Can’t damage, may assist?” Due to the shortage of regulatory oversight of the complement trade and, within the case of biotin, interference with lab assessments. Many dietary dietary supplements promoted for hair well being include biotin ranges as much as 650 occasions the really helpful every day consumption of biotin. And extra biotin within the blood can play haywire on a bunch of various blood assessments, together with thyroid operate, different hormone assessments (together with being pregnant), and the check they do to see when you’ve had a coronary heart assault––so it may probably even be life or dying.

And by way of poor regulation, as I’ve achieved tons of movies about, there are all kinds of complement producer shenanigans. For instance, this outbreak during which lots of suffered selenium toxicity as a result of that they had an oopsie, and put 200 occasions the dose, and so it ended up inflicting hair loss. And the identical factor can occur with getting an excessive amount of vitamin A.
