Do many people start hair loss management without others knowing?

It seems that hair loss is a topic that requires more caution than expected when discussing concerns.

I've heard that there are many cases where people start managing their condition after worrying alone, even though it isn't noticeable to those around them.

It’s not severe for me yet, but I keep wondering if I should start managing it in advance.

For those of you who have started hair loss management, did you let those around you know before you started?
Or did you quietly manage it alone? T_T
