What hair styles make men look older and which make guys look older?

I don't actually mean specific hairstyles. I know you can't really tell that. I'm just talking about more general stuff related to hair. I'm a 19-year-old guy, and I haven't been able to really grow any facial hair (nothing of significance anyway), or even slight sideburns in front of the ears. Today I styled it so my hair does not cover my ears (as in make them hidden in the hair), but instead there is hair pushed in front of it. I do this since I am not able to get hair to grow directly in front of my ears. Now I actually look a lot like my avatar.





Now, I want to look more my age. A lot of people guess that I'm around 15, Is it true that having hair in front of your ears makes guys look older? Since I just made that change today I don't know if anyone else will think I look older.





What else can I do to make myself look a little older, and what should I do to avoid looking younger?





I'd also like to know if it is normal for a white 19-year-old male to not have any real facial hair, including hair growing in front of the ears.What hair styles make men look older and which make guys look older?
i have never grown out too much facial hair, because it tends to make me look older





i think it is more about hair color and texture
