I can see myself not wearing when I am in my 40s or 50s, but then again maybe I will or maybe my NW3 will stay NW3 and I'll be happy with it at that age. I'll cross that bridge when it comes.

Live for the moment and decide bit by bit what to do. At the moment, I wear two partials at the hairline but use a little batch of concealer at the crown. Maybe I'll need to switch soon to a piece as my hair could get thinner.

I'd say just keep your eye on your hair and step by step make the adjustments that are manageable for yourself, wallet and what makes you happy.
