Subcutaneous blood flow in early male pattern baldness

Atherogenic index of plasma in non‐obese women with androgenetic alopecia

“…In addition, the association between arterial hypertension and AGA due to high aldosterone levels, the presence of hyperinsulinemia (which is the central element of metabolic syndrome, favoring carbohydrate intolerance and central abdominal obesity), and the effect of genetic factors (which play a role in the development of alopecia and the major hereditary component of CVD) all contribute to CV risk …”

Androgenetic alopecia and insulin resistance: are they truly associated?

“…Insulin resistance may also have an effect on scalp circulation, causing vasoconstriction of blood capillaries with reduced blood flow and, therefore, worsening of AGA. Subcutaneous blood flow was shown to be reduced in early male pattern baldness 18 and, compared with a hair‐bearing scalp, microvascular insufficiency with local tissue hypoxia was also demonstrated in a bald scalp 19 . One or more of these proposed mechanism(s) may play a role in the etiopathogenesis of AGA and, therefore, further studies are recommended to clarify these suggestions.…”

Scalp Surgery: Anatomic and Biomechanical Considerations

“…This is particularly so with respect to hair transplantation for male pattern baldness. In 1980 Klemp et al 9 evaluated scalp subcutaneous blood supply in subjects with male pattern baldness (MPB) and concluded blood supply to be reduced relative to controls. In 1990 Toshitani et al, 10 using Doppler flow meter and thermography studies, demonstrated relatively reduced flow in the central scalp of MPB patients.…”
