MPB Progression

Can rates of mpb change time to time in a person. From 2017 – 2018, my hair line went to Norwood 1 from Norwood 0. The texture of my hair changed and density decreased. From July 2018 to now, there was no change in hairline or density, remains the same. Essentially does mpb progress in a linear, exponential, or sine wave like fashion? Or is there no idea.

Moving from a Norwood 0 to a Norwood 1 is just moving from a juvenile to a mature hairline, and it is NOT balding. To be sure, I would have to see what you are referencing with some good photos.
