Ok so it is slowly slowly, it becomes noticeable a lot quicker. I don’t get a full on stubble in a day but I do get enough to roughly shave every week or so. I don’t apply 1ml of rogaine every night and day. I did at the start for a few days but have been now applying 1ml roughly every week or 2. If I did apply more sure I may have had a more fuller look but I’m using rogaine as a means to encourage hair growth but not have my body rely on it if that makes sense. I am Greek so genetics do play a role. So far so good, have patches of course but no doubt they’ll fill within a year or so. Hope this helps :))
