Age 26 is this sign of thinning crown?

Good afternoon my name John I’m 26 years old and have noticed some thinning at the hairline corners and sides. Now recently I’m not sure if it seems like the lighting or the natural whirl. But, based on opinions and experience would you think this is related to male pattern baldness? And should I do a treat meant if so? I haven’t really taken pictures or analyzed the top of my head before. My father is bald but none of my grandfathers are. I put pictures of the crown and also hairline just to give an idea. Thank you. Attachment 60893Attachment 60894Attachment 60895Attachment 60896Attachment 60897Attachment 60898

Hello, TBH it is quite hard to tell, do you naturally have very curly hair? Because it does look like you are beginning to diffuse on your crown and on top, although you may just have very curly hair and it's 'clumping' together making it look like it is diffusing.
