Finasteride 3 months before HT?

[Falconary]

I have booked for hair transplant in about 3 months from now, January 19 2022. Since I'm a diffuse thinner with nw 5 pattern, the Dr highly recommended me to take finasteride a few months ago. However, I have been to afraid to take it due to potential sides, but as of right now, Im pretty convinced that I have to take it to get better results, reduce the risk of shock loss etc. But my question is, should I postpone the hair transplant and take finasteride for a minimum of 6 months before surgery or is 3 months enough?

You can start with finasteride 3 months before the surgery but also it depends, some cases they do the surgery then starting to use the finasteride.

Could you please share some photos to assist?
