After my FFS in 2004 by Dr Z, I had three hairgrafting sessions with the brilliant Paul Cotterill in Toronto, Canada.
http://www.drcotterill.com/I was recommended to him by the dermatologist who I was seeing at London's St Thomas's Hospital for hairloss as being one of the best hairgrafting surgeons in the world.
I paid £3000 a session which was well worth it - Total £9000.00
Because my scalp had severe hairloss, typical 'M' patten, Dr Z removed a lot of non hair bearing tissue during the scalp advance because if he hadn't then I would not have had enough donor hair to fill in the baldy bits.
Also I had hairloss in the crown.
Dr Z and Dr Cotterill worked in concert together on this one and it's been an awesome success.
In fact this part of my whole transition process has been the most successful .
It also achieved like your hairline Ruby a lower hairline which I love. I don't like over high hairlines on any woman. In fact when I am out shopping, I often think to myself, that woman needs her hairline lowering by hair grafting or she needs a nose job or both !!! ..

Mind you we girls are perfectionists and what we put ourselves thru any genetic woman would shudder at ..

Another result of Dr Z removing a lot of this non hair bearing tissue, is that I still have enough donor hair for another session which is remarkable if you were to see my scalp and hairloss before my transition started.
The only slight negative of my scalp advance with Dr Z is the height of my eyebrows but it had to be a compromise with the hairloss that I had. When the inappropriate PEEK implants were inserted in my forehead in 2014 at London's Chelsea & Westminster Hospital, this raised the eyebrows a bit more but hopefully when they are removed by Facial Team in April, the eyebrows will drop down a bit.
I used to have to wear a hairpiece/wig for years but over the last 11 years I have been able to swim and play sports once again.
I will be getting another hairgrafting session done when all my forehead reconstruction is finished this April because there is some slight hairloss along the incision line since my 2014 forehead revision and there might be more after the next coronal incision with Facial Team this April.
