very unlikely you will go bald immediately because you are not really balding. Your hair looks great and noone would ever stop and think you are balding in the real world, people on here just have a finely tuned sense of the development of 'hairloss'. The thing is, the majority of men end up with some form of hairloss, and having a hairline that 'matures' (which is a euphemism for slow recession more or less) is extremely common which is why some people here are telling you to GTFO. Your hairline is good and your hair is thick all over. All you need to do is observe your hair because if you are someone with slow recession there isn't much sense medicating for a hairline that may or may not recede a few mm's in the next decade or beyond. If you start comparing pictures of your hairline every 6 months you should be able to determine if there is any more recession after a few intervals. If you get to a point where you feel it is continuing at a rate you don't like then you should consider doing something about it if its important to you, but as you are right now you have nothing to worry about, ur hair is great.
