Speculations by jpj
The following is part of a rather long message that a man who calls himself jpj posted on my Discussion Forum:
Contracting the frontalis and occipitalis muscles pulls the scalp tight and pushes downwards on the lymphatic drainage system of the scalp, thus pushing metabolic stagnant wastes away from the follicle and getting the fluids up there a'mixin. DHT is a very stagnant molecule. It easily loses the two hydrogen molecules to be turned into plain testosterone. Most of the DHT that assaults your hair was probably made in the cells of your scalp - in many cases the very same cells that are adjacent to the receptor sites in the outer root sheath of the follicle proper.
Bryan [a knowledgeable poster on another discussion forum] told me this. DHT just chemically reacts too easily with the beacoup chemicals in your bod to travel from your arm to your head unchanged. Getting the fluids in the scalp "movin" in the S.E. [scalp exercise] probably changes alot of DHT to testosterone by liberating the H2 molecules on them. More importantly the Scalp Exercise will reduce inflammation. Exercise and reducing inflammation are linked.
Wookie [another discussion forum poster] linked a super article describing this a while back. How many bodybuilders have your ever seen with pinkish, unhealthy complexions covering their muscles (unless they had a sunburn). Now, how many fat lardasses who are pre-diabetic have flushed complexions all the time? That's inflammation. The scalp exercise will make blood rush into the frontalis and occipitalis muscles and the entire scalp's capillary system. All that pressure is bound to push the blood to the extreme capillaries, pressing them open as far as they will go, ridding them of plaques and other waste gunk. When capillary walls expand, nitric oxides are released from them.
Nitric Oxide is something of a growth stimulant in its own right and is one of the reasons minoxidil and NANO are suspected to have success because of this. It's been demonstrated over the years that areas of the body adjacent to exercised muscles see a beneficial effect. Not only are more nutrients delivered via the extra blood flow (or bad nutrition if you live on Twinkies), but if you look at a weightlifter's skin around his muscles, it will generally be better aged than a sedentary person's. Less sags, fewer wrinkles.
Just by following a good diet, you can do alot for your hair too. The website hairloss-research.org considers a diet high in soy isoflavones, green tea, and adding a prostate herbal medication (usually with alot of high quality Saw Palmetto) to be about as effective as Propecia. If you don't want to take a pill, a couple of handfuls of pumpkin seeds, husks and all, probably deliver a decent amount of beta sitosterol (which is probably the effective active ingredient in Saw Palmetto - and the only common denominator in Saw Palmetto, Pygeum, Stinging Nettle, Pumkin Seed extract, and the Avocado.
The Avocado and its dietary inclusion is probably why Mexican's have so fewer prostate problems than us, by the way. It has been stated hair loss might be related to health. Yup, advanced diabetics definitely have a higher tendency to baldness than the general populace. Arterioscleratic folks and heart disease sufferers would also have higher incidences of baldness for their age groups for the reasons that we have been around and around about on in these threads. I still think, like the majority of scientists think (via a Webmd article I read) that people with a tendency to go bald inherit 4-5 (maybe 6) genes and have them all strongly expressed. Four genes scientists associate with baldness have been found. If you, like my uncles, don't have them, you can eat whatever the hell you want and be overweight (they are) and keep your teenage hairline (they have, and are in their fifties). But the rest of us have to work at it.
Comment: jpj writes, "DHT is a very stagnant molecule. It easily loses the two hydrogen molecules to be turned into plain testosterone." It would be nice to believe that this is true. I'd like to see some scientific support for this assertion. The making and breaking of chemical bonds (a chemical reaction) leading to changes in the composition of molecules like testosterone and dihydrotestosterone is a complex process.
Comment number two by an anonymous poster on my discussion forum (Tuesday, July 4, 2006):
Now, back to the theory behind healthier hair. Tom has said that when he first started the SE at the age of 19, he had a very balanced and healthy diet. I'm sure his diet allowed him to have a good deal of nutrients that are necessary for an overall healthy body in general. In addition, consuming a variety of fruits and vegetables gives one access to increased levels of phytosterols, which are known to bind to the enzyme 5 alpha reductase. This is the enzyme that also binds testosterone and turns it into the dreaded, suspected hair loss culprit DHT.
Another one of jpj's hypotheses I would like to point out is that because DHT is a very stagnant molecule, it easily loses the two Hydrogen atoms to turn back into normal testosterone. This however, chemically speaking, seems implausible. Dehydrogenation reactions, especially of stable molecules (such as DHT) do not merely proceed with "bumping" the molecule around (which could occur with vasodilation and increased blood flow). Thus, a more plausible explanation of the SE working is that coupled with a good ingestion of phytosterols (which block the enzyme conversion of testosterone to DHT), and increased blood flow leads to an increase of the presence of these phytosterols in the scalp. These then block the enzyme 5-AR, and reduce levels of DHT.
