Thinning and spot in the nape of the neck (photos)

I just wanted to ask you about this potential region of hair thinning at the nape of my neck. I attached a photo below that shows this in clear lighting. What are your thoughts about this? I have noticed this for around a year now. I am 19 years old with no known deficiencies. The first photo is the spot a year ago. The second photo is the spot now.

I don’t see the spot now. Thinning nape of the neck hair is genetic but not associated with Male Pattern Balding directly.  Nothing to do about it.
