Bookmarking — the dossier-vs-overview split is the right call. Most of the time I want overview; sometimes I want receipts.

Pattern hair loss is likely accelerating in the developed world because underlying health factors are not being addressed.

◐Partially SupportedHair loss can be broadly categorized into pattern hair loss and hair cycle/shedding disorders.

◐Partially SupportedPattern hair loss has significantly increased among young men in China since 2010, correlating with Westernization.

◐Partially SupportedHair shedding disorders are almost always temporary, with hair cycles normalizing and hair returning to normal within 3-8 months after addressing the underlying cause.

◐Partially SupportedThe dermal papilla cell cluster is crucial for hair follicle size, and reduced count leads to thinner hair.

◐Partially SupportedStress can cause hair shedding and accelerate pattern hair loss in predisposed individuals.

◐Partially SupportedAccelerated hair follicle cycling can speed up androgenic alopecia processes.

◐Partially SupportedDHT attacks dermal papilla cells in pattern hair loss, inducing TGF-beta 1 and apoptosis.

◐Partially SupportedVitamin D deficiency in Americans corresponds with telogen effluvium-based shedding.

◐Partially SupportedAddressing underlying health factors may be crucial for individuals non-responsive to finasteride for hair loss.

◐Partially SupportedPattern hair loss may be accelerating in the developed world due to unaddressed factors.

◐Partially SupportedUnderstanding the individual causes of hair loss is crucial for achieving desired outcomes.

◐Partially SupportedThe incidence and age of onset of pattern hair loss are increasing in the Westernized world, potentially due to factors like poor sleep quality, long working hours, processed foods, sugar, and nutrient deficiencies.

◐Partially SupportedAndrogenic alopecia may be accelerated by stress, nutrient deficiencies, and telogen effluvium.

✕Not SupportedReducing only DHT to target male pattern hair loss may yield suboptimal results because it doesn't address other contributing factors like stress and nutrient deficiencies.

✕Not SupportedDoctors often have insufficient time to thoroughly assess a patient's overall health, diet, environment, and activity levels when diagnosing hair loss.

◐Partially SupportedAutoimmune and scarring hair loss are related to immune system dysregulation of the hair follicle, potentially triggered by environmental factors and gut dysbiosis.
