When to get FFS?

I’ve read I should wait a year after starting HRT. But I want to get it done on my 6 months. Is it really necessary to wait a year?

Full disclosure I’m closer to 40 than 30 and recently cracked my egg so I feel like I can’t wait any longer I’ve waited so long already.

In response to the comments so far: thank you! More context:

I’m paying out of pocket and chose Dr. Torres in Argentina. My major source of dysphoria comes from my forehead - my hairline and brow.

I already had my rhino done, already had my laser hair removal done, already had FUE AND already grew out my hair (all of this in the past 4 years) and I JUST accepted, OK I’m not NB/genderfluid etc I’m a doll haha

For me HRT was more about the body feminization I hope to achieve than facial because I recognize it’s BONE work.
