The Hair Loss Encyclopedia
Estriol is a weak estrogen hormone primarily produced during pregnancy by the placenta, and it plays a role in regulating various physiological processes. In the context of hair loss, estriol's relevance lies in its potential influence on hair follicle biology and the hormonal balance that affects hair growth cycles. Unlike stronger estrogens, estriol has a lower affinity for estrogen receptors, which may result in less pronounced effects on hair density and growth. Understanding estriol's role can help in exploring hormonal treatments for conditions like androgenetic alopecia, particularly in women.
