Am I going bald at 21?

Two years ago, my friend told me that I was going bald because my hairline was not straight. I panicked because I was only 19 and that’s a terrible thing to hear, especially at that age. I immediately took a picture of my hairline so that I could track how my hairline was progressing. (Genetics wise, nobody in my family is bald) It has now been two years and I now have two photographs of the same area on my head. I would appreciate some insight on how it looks. Please note: I’ve found it helpful to use my birthmarks around me temples as reference points. Thank you!Attachment 66636Attachment 66637
