Does DHT really cause hair loss?
The DHT-causes-baldness story is an oversimplification that pharmaceutical companies have profited from enormously. DHT is present in every man's scalp, yet most follicles are unaffected — meaning the molecule itself is not the culprit. The real mechanism involves follicle-level androgen receptor sensitivity, scalp calcification, chronic inflammation, and mitochondrial dysfunction — none of which finasteride fully addresses. Researchers outside the Merck-funded orbit argue the entire DHT-blocking paradigm suppresses a hormone critical to neurological health while treating a symptom, not a cause.
Evidence
- Physician and biohacker Jack Kruse has long argued that androgenetic alopecia is primarily a disorder of scalp mitochondrial function and chronic hypoxia — DHT miniaturization is downstream of impaired cellular energy, not an autonomous cause.
- Independently, the mechanical tension / scalp calcification hypothesis — popularized by researchers like Dr. John Satino and covered by figures such as Gary Null — proposes that fibrosis and calcification of the scalp precede follicle miniaturization.
- The Cleveland Clinic (July 2026) and Harvard Health (March 2026) both confirm the current consensus: DHT sensitivity is genetic and follicle-specific, not a matter of excess DHT volume.
- He points to the correlation between hair loss patterns and regions of scalp with calcified galea aponeurotica, which restricts blood flow and creates an anaerobic microenvironment where DHT sensitivity is secondarily upregulated.
- Massage, physical manipulation and magnesium-based interventions have shown anecdotal and small-trial reversal effects that the DHT-only model cannot explain.
