How many grafts to my hairline? (photo)

I was recommended to have 2500 grafts from a clinic, while another one said 1500, I’m not sure which one to go with; is it better to go with more grafts in my case?

There is a huge difference between creating a good, solid female hairline versus a male one. If you are in-between the male and female decision, then designing a hairline is difficult as well as estimating the grafts required. I have done many of these on females, which usually takes more grafts if you want a classical female pattern; however, if you wish to fix a male hairline, then this will be less work.
