Snippet from the article:
The group aimed to see how energy drinks affect heart health, given that these drinks, along with dietary supplements, are not regulated as stringently as new drugs that must meet Food and Drug Administration (FDA) safety requirements, Shah said.
In a literature search, they identified seven observational and interventional trials that evaluated the impact of energy drinks on QT interval, blood pressure, and heart rate.
Three studies with a pooled sample of 93 subjects had QT/QTc data. Six studies with a pooled sample of 132 subjects had blood-pressure data, and seven studies investigated heart rate.
The patients, who were all young (aged 18 to 45) and healthy, underwent ECG and blood-pressure testing before and just after drinking one to three cans of energy drinkâ€”most commonly Red Bull, but also others such as Full Throttle and Meltdown RTD. An 8.4-oz can of Red Bull contains 80 mg of caffeine, compared with 35 mg of caffeine in a 12-oz Coke or about 100 mg of caffeine in an average cup of coffee, Shah said.

It’s not hair loss related, but it’s worth a post…
This is a study by Dr Sachin Shah, presented at the American Heart Association Nutrition, Physical Activity and Metabolism / Cardiovascular Disease Epidemiology and Prevention (AHA EPI-NPAM) 2013 Scientific Sessions.
According to the report, the increase buzz may be the result of caffeine alone, but the changes in the EKG has not been explained and the relevance of it is not clear.
