But - read up in the side effects and potential risks, they can both cause other issues in some people, and for me it took a while to find the right finasteride dose.
Another downside is oral finasteride use means I can no longer give blood.
Minoxadil increases blood flow and restores the natural growth cycle lengths of weakened follicles. This is applied topically, and promotes hair growth pretty much anywhere - beard, crown, temples. You can take it orally, and it will promote hair growth everywhere (more body hair). However, it can't fix follicles already dormant or scarred over. So if things are already bald, it may not give the results you want.
A word of warning that about 5% of those who take Minoxadil experience a shedding period where it gets worse. Because it restores normal hair follicles growth cycles, this includes the process of pushing out old hairs. This is not permanent and will last, at most, a month. This is why most providers like "Keeps" will try to sell in batches of 3 months.
In 2026, a new drug will finish phase 3 human trials. That one targets (IIRC) stem cells and can restore even advanced hair loss where the follicles are dormant or dead. Very exciting!
My hair is very grey now which I think makes it also look thinner, but I don't want to dye it - though I tried Alpecin 'grey targeting shampoo' and it turned my hair blue... Not a good look for the office and extra visible in video calls
It's also pretty trivial to prevent or recover at onset. Finasteride and minoxadil are FDA approved on-label prescriptions for it (well, the later is OTC).
Dermatologists will happily write the prescription and check in with you as often as you want to schedule.
