Those two pictures are taken in the exact same location and way, being with wet hair under the heat lamp after a shower with flash on. I think the first one just looks different since I missed framing it and took it far too close as where the second one is further back which I also think messed with the white balance, I cropped the 2nd one to like a 4th of it's size.
You can see the regrowth the best in my first hairloss album which I posted months ago, I also attached a more recent hairline shot

Currently my density is improved but I still have a bald patch on my crown and my hairline is still awful but not quite as bad, I'll probably make my own post on Reddit once I feel my regrowth is significant enough. I've taken lots of pictures and I was doing updates at one stage but I got lazier as my hair got better as the anxiety of hairloss used to drive me.
