No. They work by separate mechanisms so if you start minoxidil then you have to stay on it to keep its gains. You can't "maintain" them with finasteride only. It seems like so many hair loss forum users make this mistake with disastrous results. It would be like saying, "I've been drinking beer and weed tonight and I feel really good. But if I cut out the weed and drink only beer, can I stay both drunk AND high?"
