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 forestall 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 numerous myths on the market. The vast majority of hair loss with age is genetic for each men and women, within the case of this research. Based mostly on twin research, the heritability of baldness in males is 79 p.c, that means about 80 p.c of the variations in hair loss between males is genetically decided. However that also leaves some wiggle room.

Even if in case you have equivalent twins––equivalent 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 kids, or having a historical past of hypertension or most cancers. For instance, take a look at these two equivalent twin brothers. Identical genes, however the twin on the best reported extra stress in his life. On this pair, the equivalent twin on the best 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 might harm the DNA in hair follicles, and trigger microvascular poisoning within the base of the follicle. Different poisonous brokers related to hair loss embody mercury, as a result of it appears to pay attention about 250-fold in rising scalp hair. In reality, possibly the explanation Shakespeare began shedding his hair was because of mercury poisoning from syphilis remedy. Fortunately, medical doctors don’t give individuals mercury anymore. Nowadays, because the CDC factors out, mercury primarily enters the physique by seafood consumption.

“Girls of reproductive age continuously search remedy for what’s considered hormone-related hair loss particularly at menopause.” However, for instance, this girl got here in with hair loss, and blood assessments indicated elevated mercury ranges. And, no marvel, as she had a food plan 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 come back again, and after seven months sustaining a fish-free food plan, her hair utterly regrew. So, medical doctors ought to think about screening for mercury toxicity after they see hair loss, since there’s one thing we will do about it. Instructing sufferers to scale back fish consumption and repeat blood assessments might provide aid of signs, and uncover dietary habits which may be a supply of heavy metal-induced hair loss. Although admittedly, generally heavy steel 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 function. Normally, there’s little proof to recommend that vitamin and mineral supplementation advantages individuals, until they’re truly poor.

For instance, we’ve recognized for hundreds of years that scurvy, extreme vitamin C deficiency, may 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 fable that dietary supplements containing zinc will enhance hair progress––until you’ve got zinc deficiency, like in the event you’re an alcoholic or one thing. However if in case you have regular zinc ranges in your blood, taking extra zinc received’t assist, and in reality can have adverse uncomfortable side effects. It’s the identical factor with taking iron dietary supplements.

The most typical ingredient in top-selling hair loss merchandise is vitamin B7, also called biotin. Sure, biotin deficiency causes hair loss, however there aren’t any evidence-based information that supplementing biotin promotes hair progress. And extreme biotin deficiency in wholesome people consuming a traditional food plan has by no means been reported. However in the event you eat uncooked egg whites, you may 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 fable 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 useful day by day consumption of biotin. And extra biotin within the blood can play haywire on a bunch of various blood assessments, together with thyroid perform, different hormone assessments (together with being pregnant), and the check they do to see in the event you’ve had a coronary heart assault––so it might probably even be life or dying.

And when it comes to poor regulation, as I’ve achieved tons of movies about, there are all kinds of complement producer shenanigans. For instance, this outbreak during which a whole lot suffered selenium toxicity as a result of they’d 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.

Please think about volunteering to assist out on the location.
