My friend says that Dr Mercola (?) says that Insulin Growth Factor 1 causes hair loss. What is IGF 1 and what is its relation to insulin? Is the theory nonsense? Shall I pack in the booze and Diet Coke, as they lead to an insulin surge?
I think the doctor your friend was refering to was Dr. Mirkin. He's got a radio show and a website:

Dr. Mirkin has lots of ideas on hairloss:

HAIR LOSS AND INSULIN
Gabe Mirkin, M.D.
Exciting new research shows that high blood levels of insulin and its growth factors may cause male pattern baldness in which men and women lose hair from the top and front of their heads, while hair on the sides of their scalp continue to grow luxuriously. A study from Harvard School of Public Health shows that men who have the highest blood levels of insulin like growth factor-1 are the ones most likely to suffer male pattern baldness. Women who have high levels of insulin (polycystic ovary syndrome) are the ones most likely to lose hair from the tops of their heads. It still is early in the research, but evidence is accumulating that male-pattern baldness may be caused by high levels of insulin that are produced by eating huge amounts of sugary and floured foods such as bakery products and pastas. We need research to show if male pattern baldness can be prevented by avoiding flour and sugar, eating fruits only with meals and taking drugs such as Glucophage, Actos and Avandia that lower insulin levels.

MALE-PATTERN BALDNESS
Gabe Mirkin, M.D.
More than three years ago I reported that the present treatment for male-pattern baldness is almost worthless and that male-pattern baldness may be caused by insulin resistance, which means that eating sugar and flour contribute to hair loss. The prevailing explanation, that baldness is caused a male hormone called dihydrotestosterone, does not tell us what men do to lose their hair at a young age.
A study in Lancet ( September 30, 2000, page 1165) shows that male pattern baldness may be caused by insulin resistance. When you eat, your blood sugar level rises.. To keep blood sugar levels from rising too high, your pancreas releases insulin which drives sugar from the blood into your cells. Some people can't respond to insulin so their blood sugar levels rise too high and then they produce way too much insulin that may cause both men and women to lose hair. Men who are at high risk for male-pattern baldness store fat primarily in their bellies, rather than their hips; have high blood triglyceride levels, have low blood levels of the good HDL cholesterol that prevents heart attacks, have a family history of diabetes , and are at high risk for suffering a heart attack and eventually developing diabetes. They can help to prevent diabetes, heart attacks and possibly male pattern baldness by eating lots of fruits, vegetables, whole grains, beans, seeds, and nuts. Avoid foods made with flour, white rice, milled corn and anything that has sugar added. Eat fruits and root vegetables such as potatoes only with meals.

NEW BREAKTHROUGHS IN MALE PATTERN BALDNESS.
Report #6943; TWO
We used to think that male-pattern baldness,/ on the top of the head/, is caused by a derivative of the male hormone called dihydrotestosterone. Recent research show that theory may be wrong and that male-pattern baldness may be caused by a combination of an infection and the female hormone, estrogen.
In the first study, French researchers report in the Journal of Dermatologic Treatment, that biopsies of the scalp in men with male-pattern baldness show signs of infection/ particularly a marked increase in the density of activated T cells and IgG antibody deposits. When men with male-pattern baldness rubbed an antibiotic cream on their balding heads for 10 months (piroctone olamine and triclosanon), biopsies showed that their T cells and IGG deposits disappeared and the rate of hair loss slowed down to normal. Another recent study in the Proceedings of the National Academy of Sciences shows that the female hormone, estrogen, in mice puts hair into a resting stage that can prevent hair from growing/ and/ that giving hormones that block estrogen causes the hair to start growing again. If these studies can be duplicated by other researchers, the future treatment for male-pattern baldness may be to shampoo daily and then apply a special antibiotic cream to the scalp. I am sure that studies will start soon to see if a cream containing the anti-estrogen drug, tamoxifen, stops male-pattern baldness from progressing. More than 30 years ago, several studies showed that a cream containing another female hormone, called progesterone, slowed hair loss in male pattern baldness.
