hormones that circulate unbound in the bloodstream
Free androgens are a type of hormone, like testosterone, that circulate in the bloodstream without being bound to proteins. These unbound hormones are biologically active and can directly interact with cells, influencing various bodily functions such as hair growth, muscle development, and reproductive health. Elevated levels of free androgens can contribute to conditions like acne, hirsutism (excessive hair growth), and androgenic alopecia (hair loss).
