Can’t get this little bit of hair on my hairline to grow past a certain point

Hi there so I (23m)have been on finasteride for 18 months and minoxidil for 9 I have recently switched over to dut 1 month ago instead of fin as I had stabilised really well on fin but never had any regrowth

However I have always had this little bit of hair in the front of my hairline that no matter how much I grow my hair never seems to get past the halfway point of my forehead even though the rest of my hair grows really long I’ve tried hair vitamins biotin all of it but nothing has helped so far I have added pictures to show what I mean

The rest of my hair is thick all the way through it’s just the hairline

Also side note I want to start taking creatine would this be a bad idea?
