I'm searched PaleoHacks quite thoroughly for topics pertaining the Male Pattern Baldness and the diet connection but I haven't found anything information that I thought was worthwhile or certain.
Searching the internet, there appear to be a multitude of studies showing a link between IGF-1, SHBG, and insulin. I just want to know if anyone here believes that there is a true link and if removing yourself from a SAD way-of-life can protect you from MPD. Feel free to cite any studies or first-hand accounts.
"We show that prostaglandin D(2)
synthase (PTGDS) is elevated at the
mRNA and protein levels in bald scalp
compared to haired scalp of men with
The product of PTGDS enzyme
activity, prostaglandin D(2) (PGD(2)),
is similarly elevated in bald scalp.
During normal follicle cycling in
mice, Ptgds and PGD(2) levels increase
immediately preceding the regression
phase, suggesting an inhibitory effect
on hair growth.
We show that PGD(2)
inhibits hair growth in explanted
human hair follicles and when applied
topically to mice.
inhibition requires the PGD(2)
receptor G protein (heterotrimeric
guanine nucleotide)-coupled receptor
44 (GPR44), but not the PGD(2)
receptor 1 (PTGDR).

If you click on the link below, you'll be able to download a free article by Loren Cordain and the Drs Eades on the connections between the SAD and many disparate conditions -- including male pattern baldness. The section on baldness is pretty darn short compared to the whole rest of the article, but if you're truly interested in the issue, the whole thing is definitely worth a read. Great info. (Covers PCOS, cancer, acne, myopia, male baldness, and others.)
One of the big things leading to hair loss is stress. Part of the Paleo lifestyle is reducing stress, whether through exercise, proper sleep or diet. The diet part is eliminating foods that cause inflammation, thereby reducing physical stress. Another part of it is restoring proper hormone levels, which is another reason we lose hair. In my case genetics plays a very large role, so I am doomed. My hair loss did slow, but has not stopped.
A lot of this is related to DHT vs testosterone - if you don't have enough testosterone receptors in your muscles, the free testosterone gets turned into DHT, which certain hair follicles are susceptible to.
Using polysorbate-80 as a shampoo can help remove the excess DHT and prevent further hair loss... (You'd wet your hair, then rub a small bit of polysorbate-80 in your scalp for about 3-4 minutes, then rinse it out.)
Or you could pack on more muscle.
Adding some zinc can help prevent the conversion too.
