Several small or few larger FUEs

[pstolen]

Hi!

Due to thinning hair i had an 1100 grafts FUE procedure 2 years ago. My hair has continued thinning and I am now considering having a new procedure.

But I wonder if I should do a small procedure now, or if I should wait and do a more comprehensive procedure later.

In general, what are the pros and cons regarding small vs. larger FUE procedures?
Is there any disadvantage to performing several small treatments?

Thank you for all answers
