The conversation discusses using peppermint oil for hair loss, with one user applying it undiluted to the scalp and another combining it with finasteride and microneedling. Some believe in its effectiveness despite limited scientific evidence, and also mention rosemary oil as potentially beneficial.
Finasteride is metabolized in the liver and excreted through urine and feces. Users humorously discuss its excretion, with one joking about it being expelled through ejaculation.
