...I suggest you do shave before MPB kicks in completely though.
How much hair loss would you consider "before MPB kicks in completely"? I just want to know what to look for.
Unless you want to make a preemptive strike before it recedes to a noticeable degree, I think your hairline looks fairly full. It's not receding at the temples, so it just looks like a high hairline.Do what makes you happy.
Honestly dude, unless your hairloss is very aggressive, you've got years left. I'm 25 and my hairline is wrecked, yours looks 100% to me. Enjoy your hair while you still have it, soon enough you won't have the choice.
Take a little time and enjoy what you have now, just don't hold on to a few ridiculous strands thinking theres more there than there really is, but you are a long way from that situation at this time.Oracle
