Is it okay to use oral and topical min both together?

To all those who have used oral + topical min together and to even those who didbt i wanna asj you is it better than just sticking to oral itself? So i was taking oral 1m25mg for 2 months had a good gain later on switched the brand and upgraded to 2.5mg been on this brand for 2 month , all my gains lost + hairfall increased severly this brand dint worked for me , so now i am going back to the same brand as previously i was usijg ( lonitab) but this time i m thinking to add topical 5% solution as well to my routine for 1 ml a day , like 2.5mg oral tablet + 5% 1ml topical soln a day and 1mg fin? Is it good? Will it give me better and faster result? Or is it just a overkill?
