A patent dug up from 2001 outlines a method to reduce or reverse hair loss by injecting the scalp with Botox.

Two Toronto, Canada-based doctors named Marvin Schwartz and Brian Freund claim the following:

Injection of (Botox) improves the tissue environment surrounding the hair follicles by reducing scalp tension and, by doing so, improves bloodflow through the arteries. In turn, the tension in hair-bearing tissue is reduced and hair growth is stimulated.

and that you’re losing your hair because of your trampoline:

The anatomy of the scalp can be conceptualized tension-wise as trampoline-like. Over the scalp area, the layers beneath the skin are an unyielding fibrous layer called an aponeurosis (galea aponeurotica). The muscles surrounding the scalp (..) are analogous to the springs which would tension and hold taut the tarp of the trampoline. Blood vessels carrying oxygen and nutrients must traverse this area to provide a suitable environment for hair follicles to flourish. When the muscles surrounding the scalp tighten, the areas of scalp mechanically under the highest tension are the vertex and frontal areas. Thus, the most common areas of male pattern baldness correspond to the areas under highest tension. The inventors have found that by reducing the tension of the musculature surrounding the scalp, tension in tissue of the frontal and vertex areas is also effective reduced. This reduction of tension (..) permits an increase of blood flow into that area of the scalp.

The doctors seem like Botox believers in general, suggesting it be used for whiplash, headaches and oral surgery. Some lucky bald guy with an overbite that fell off a ladder recently is in for a treat.

Reportedly Germans have been doing it for a year with some unimpressive results, but have hope: some other Canadians on the opposite side of the country may have better luck in a trial that was scheduled last January.
