Cause of male pattern hair loss – is the answer to be found in the face?

[user27041995]

Hypothesis on the cause of male pattern hair loss: Increased muscle tone (chronic contraction) of the facial and masticatory muscles as a result of psychophysiological conditioning (stimulus-response pattern) caused by interpersonal interaction.

This is what ChatGPT says: 

The idea that increased muscle tone or chronic contraction of the facial and masticatory muscles can lead to hair loss is considered pseudoscience. There is no scientific evidence to support this claim, and it is not a recognized cause of hair loss by the medical community. Hair loss can be caused by a variety of factors, including genetics, hormonal changes, medical conditions, and certain medications. Therefore, it is important to consult with a healthcare professional to determine the underlying cause of hair loss and develop an appropriate treatment plan.

This is just the blutflow theory.

If it were true, wouldn't hair transplants and 5AR inhibitors be ineffective in people already prone to hair loss?

Yes

The consequence of the extraordinary tension (increased muscle tone/chronic contraction) of the muscles mentioned could be an increased regional tension of the scalp and the galea aponeurotica (a) and/or a direct permanent squeezing of blood vessels by the tensed mimic muscles and the masticatory muscles (b) and/or a malposition of the mandible (c).

(a) The consequence of the increased regional tension of the scalp and the galea aponeurotica could be inflammatory processes. Chain of effects: Inflammation → DHT at scalp sites → TGF beta 1 → scarring of the hair follicles → hair loss.

(b) The consequence of a direct squeezing of blood vessels by the tensed mimic muscles and the masticatory muscles could be a disturbance of blood circulation and thus an obstruction of the removal of metabolic products from the scalp sites. The assumption is that especially the veins (function: blood backflow to the heart) are affected. Chain of effects: Accumulation of metabolic products at scalp sites → Inflammation → DHT at scalp sites → TGF beta 1 → scarring of the hair follicles → hair loss.

(c) The consequence of a malposition of the mandible could be a squeezing of blood vessels, whereupon a regional circulatory disturbance occurs, i.e. an obstruction of the removal of metabolic products from the scalp sites. Chain of effects: Accumulation of metabolic products at scalp sites → Inflammation → DHT at scalp sites → TGF beta 1 → scarring of the hair follicles → hair loss.

The assumption is that the degeneration process (a/b/c → scarring of the hair follicles) takes place over a period of about 5 to 20 years, until the function of the hair follicles is so severely impaired that there is clearly visible hair loss. The basis for this assumption is the observation of people with transplanted hair, whereby the transplanted hair follicles – contrary to common claims – are apparently also affected by the described degeneration symptoms after a certain time.

On 5AR2 deficiency/5AR inhibitors:

Men who are castrated before puberty or are born with a congenital 5AR2 deficiency develop a phenotype that is rarely male, gender ambiguous to completely female. This means that these men have, among other things, a female skin structure, thinner skin, lower muscle mass and strength. These two groups thus develop the physiological characteristics that are (according to theory) causal for the absence of pattern hair loss in women – despite an increased tone of the mimic muscles and the masticatory muscles. A possible side effect of 5AR inhibitors is gynecomastia (enlargement of breast tissue in men). 5AR inhibitors can therefore apparently change parts of the physiology. So 5AR inhibitors can possibly also alter the parts of physiology that are hypothesised to be causative for hair loss.

Basically, a major contributing factor to male pattern baldness is your genes, and when your male hormones (DHT) attack hair follicles and destroy them. These are the conditions when you're most likely to experience male pattern baldness. Studies have shown that poor nutrition, smoking, and mental stress can contribute to this condition.

These factors can trigger male pattern baldness:

• Emotional stress
• Low water intake
• Poor sleep
• Fluctuating diet changes
• Using anabolic steroids
• Medications

The shape of the face has no role to play in male pattern baldness.

Thanks! Hope this helps!

Plenty of men have great health and still go bald. Your comment only serves to stigmatise balding as a sign of poor health. 

It is almost entirely genetic and simply relates to the follicles sensitivity to DHT.

We've correctly sniffed out DHT as the culprit in 1916, conspiracy theories like this don't help people.
