I keep wondering if it's right for me to start taking hair loss medication.

I feel like my hair has thinned over the past few months, so I'm thinking of getting a checkup, but I'm a little scared to start medication.
It doesn't look severely hollow yet, but I can't decide whether it's better to manage it before it gets worse or if I can just watch it.
For those of you who have started hair loss treatment, I'm curious to know what prompted you to visit the clinic and what you were most curious about during your first consultation!
