.. I'm speechless that you actually slogged through this (let alone found it)~!
I know it's not an easy read, it's primarily for a few artists who like to know about Alacrity's background[in particular *SiegeRedwolf and *Rikona who are at present working together on a pictorial bio],
plus a handful of curious bystanders.
Alacrity's age at "retirement" is in her mid-forties; her greying hair is indeed a combination of stress and age, and gives her an even more ambiguous appearance.
It is more than just a cosmetic change reflecting her life (after all, greying hair could be dyed should she choose);
it also signifies her mental state at that time - in the process of reinventing herself, Ala accepts such changes.
