I have looked at my hair over the years in pictures (I'm 60) and it is interesting to me how it has changed. When I was 2 I had this long, wild, wavy hair and then when I was 5 it was almost perfectly straight. Then it had a slight wave and then was gorgeous when I was 20 then got strange, etc. What I found interesting was to think about "who" I was during each time period, what was going well/badly and I think I can sometimes see it in what my hair does!
