Hi Declan,
HDC only do consultations in London, they perform surgery in Cyprus.
1. Yes, I've seen some good results from them.
2. No, 4000 grafts will cost you 10600 Euro.
3. No, your doctor or a nurse can take them out.
I'm from the UK and I flew to Dr. Rahal in Canada and I'm thrilled with my result. 4000 grafts with Dr. Rahal will cost you 8745 Euros in today's exchange rate.
Hope this helps
