If you want to keep your hair, start Minoxidil now. Yeah, you’ll have to stick with it, but quitting later just means losing what it helped keep. Shedding happens, lasts a couple months, then you see results in 6-12. Waiting won’t stop MPB.
Finasteride is what actually stops hair loss. If you can’t get it, look into alternatives. Overseas pharmacies, telemedicine, whatever works, check the product finder. Minoxidil helps, but without Fin, you’re still losing ground.
