Hair loss is linked to cellular physiology and the IGF-1 to TGF-B1 ratio, not just androgen sensitivity. The theory lacks evidence, while finasteride and minoxidil are effective treatments.
Finasteride is not linked to a 60% risk of persistent sexual dysfunction; this figure applies only to those already experiencing sexual issues. Most users do not have side effects, and the study's methodology is criticized for selection bias.
Oral minoxidil dosing should be based on body weight to minimize side effects, with higher doses increasing risks like pericardial effusion. Combining oral minoxidil with topical treatments and finasteride can improve hair growth, but regular heart health monitoring is essential.
Dutasteride and finasteride have similar risks of sexual dysfunction for treating androgenetic alopecia. Users experience varying side effects, indicating individual differences in drug reactions.
