At what point do I worry?

[L90]

I've been losing hair at my temples for a long time now, more recently it's creeping more towards the center of my hairline even though I've been on 1mg of Fin for a long time also.

Should I up my fin?

I've just started microneedling with a pen once a week and using min twice a day. It seems like one area I've been putting the min on is maybe getting thinner. I've read about thinning and shedding when you first start using min. At what point should I be worried about it not starting to work though? I don't want to keep thinning what I have left if it's not going to regrow my hair or thicken up what I have

My friends and I had hair loss problems until we started going to the sauna.
After systematically improving circulation, I noticed that my hair became stronger!
I bought myself a round sauna and put it on the property. Now I go every day and feel great.
