Welcome! I see faint signs of thinning, but nothing to panic over just yet. Try a short buzzcut first if you think going sly is a bit extreme for now...You can always elect to go sly when the full blown MPB kicks in. Good luck!
I can see some thinning at the crown but hair loss is a gradual process so you don't need to do anything just yet. Being aware of what's going on is helpful because you'll be prepared to take action when the time comes.
