Comparing Hair Growth After 2 Weeks Post-Buzz Cut: Regrowth or Just Longer Hair?

First picture was taken today, I scrubbed my hair upward with my hands to make any thinning more visible.

Second picture was taken 2 weeks ago immediately after I buzzed my hair, it was completely dry, I mean the cut was done with dry clippers, no water used at all so my hair ain’t wet or damp in that picture.

Does this look like actual regrowth/thickening, or just normal growth in hair length?

Looks more like normal hair growth lengthwise over two weeks. Full regrowth usually takes longer.
