"…the cortisol count in hair is the most reliable measure of the [stress-related] hormone to be found by scientists to date."
(Israel)—Several studies by Israeli-Canadian researcher Dr. Gideon Koren have revealed that a person's hair can be used to determine stress levels and also a person's risk of having a heart attack.According to the Israel21c report, the hormone cortisol is produced as a person experiences stress, and is present in hair follicles.

"As cortisol is a known biomarker for stress," explains Dr. Koren, "and because hair grows about a centimeter [0.4 inch] a month, I thought this was a great opportunity to measure chronic stress over time."
Israel21c reporter, David Shamah, went on to note the "cortisol count in hair is the most reliable measure of the hormone to be found by scientists to date. Previously they had to rely on measures of cortisol in blood or urine, which record only a few hours' or days' worth of the hormone. Thus, depending on hair length, a doctor could determine how much stress a person has been under for the preceding six months or even more, and whether or not those stress levels have increased recently."
