My hairline looks the same as yours .. but I keep my hair long. I am 25 and noticed significant hairloss when I was 20.. But I only started using the med recently
fin -8 months minox 10% - 4 months. I think rate of hairloss has subsided now but it looks like I am still thinning in the front at a faster rate. For me, the hairloss has worsened and my hairline looks much different than when it was at 20. Your best bet would be going to a doc. and getting a prescription.. I heard the meds work great when you are young. For me , I don't find them to be miracles,but they are the only option I got. Other suggestion I get from many people is try not to stress out too much about hairloss. Seems to be the best option out there but it's very difficult to follow..
Best of luck.. keep updating your thoughts and progress
