Building Scalp Infrastructure to Nurture Vellus Hair into 'Thick Hair'. A Practical Manual for the Temporomalis Muscle Pump via Chewing and 'Hair Shaft Diameter (Thickness) Tracking'

Many people with hair concerns observe only the “visible transparency of their scalp (widening of the crown or hairline)” in the mirror every day, and if it looks even slightly progressive, they panic and reach for new, expensive hair growth tonics.

However, “visible changes (transparency and number of hairs)” are entirely lagging indicators (results). By the time you notice them, the “soil (capillary network)” of your scalp has already turned into scorched earth, and the hair matrix cells have fallen into a state of long-term oxygen deprivation.

The most certain physical approach to halting the progression of hair thinning (AGA or FAGA) and rebuilding the scalp infrastructure is the “dynamic operation of the temporalis muscle (masticatory muscle near the temples)” (blood flow pump circuit in E13). The absolute KPI meter to measure whether this intervention is “really working” is the “tracking of hair shaft diameter (thickness and stiffness of hair).”

The “Extension of the Anagen Phase” Triggered by the Chewing Pump

Why does hair become thinner and turn into vellus hair (soft hair)?

It is because, due to lack of blood flow and microscopic inflammation (cytokines like IL-6), the hair cannot fulfill its original lifespan (an anagen phase of several years) and is forcibly transitioned to the “catagen phase (preparation for falling out)” in just a few months (hair cycle bug in E12).

1. Restarting the Temporalis Muscle (Engine): By choosing hard-texture food ingredients and “chewing off 40 times per bite” at every meal, and continuously chewing gum powerfully during daytime desk work, the temporalis muscle begins to work fiercely as a pump.
2. Bombardment of Blood Flow and Extinguishing Inflammation: When the volume of blood flow defying gravity to reach the top of the head increases drastically, stagnant fatigue substances and inflammation signals (IL-6) are washed away.
3. Rebirth of “Thick Hair”: The hair roots, whose supply routes (infrastructure) for nutrients and oxygen have been restored, begin walking the several-year “anagen phase” once again without running out of strength halfway. As a result, the hair goes back to taking root deeply, thickly, and stiffly.

”Hair Shaft Diameter (Thickness) Tracking Protocol” You Can Do at Home

Even without using the expensive microscopes at AGA clinics, it is possible to score your scalp blood flow (the performance of the temporalis muscle pump) extremely accurately using just your morning routine.

1. Sorting “Fallen Hair” (Looking for Thin, Short Hairs)

• Observation: Fix a date and time, such as the second Sunday of every month, and pick up 20 stray hairs at random during hair washing or from your pillowside upon waking up, and line them up on a piece of white paper.
• Abnormality Score (Vellus Hair Rate): Count what percentage of these are “thin like vellus hair, light in color, and moreover short (with a pointed tip).” With a healthy scalp, fallen hairs are all thick and long, and the hair root is round like a matchstick (telogen effluvium). If vellus hair exceeds 20%, your scalp is oxygen-deprived (IL-6 is inflamed).

2. “Pad of the Finger” Touch Test

• Measurement: Pinch a single hair from the healthiest part of the back of the head and slide it between the pads of your fingers. Use that “taut stiffness (thickness)” as your baseline.
• Comparison: Next, pinch a hair from the crown or frontal area (hairline) where thinning hair is most likely to progress in the same way, and slide it. Memorize (or record in your smartphone’s notes) the “lack of body (softness, limp feeling)” at this time.

When you continue a lifestyle of maximizing your chewing count (making the texture of meals hard and tiring out the temporalis muscle every day) for 3 months, this “pad of the finger touch test” and the “percentage of vellus hair” will dramatically improve (increase in thick, black, stiff hairs).

Rejoicing while looking in the mirror saying “Hair grew / The number increased” is for amateurs. The true evidence that the powerful jaw movement of the temporalis muscle has restored the blood flow pipes of the scalp appears only in the overwhelming presence of “thick, pitch-black, tough fallen hairs” dropped at your feet.
