Is this a mature hairline?

[Lisciu94]

I have noticed a differrnce in my hairline since i was 15 and now Im 26. I went to a trychologist , she examined my head like a year ago and she said that i have healthy hair and that i have a high hair growth but my hairline seems to be going back a little. I used seboradin men , hairgen and i microneedled but i didnt get any results . Is this like a genetic mature hairline that needs no intervention and will eventually stop maturing? No males on both sides of the family are bald . My dad has thick long hair and is like a norwood 2.5 at 50. , both grandpas on both sides of the family are like between norwood 2-3 and theu are 70 years old. My uncles are like norwood 2. Do I need to worry?
