Not all the hair transplant clinics are ethical enough to regularly reject patients who are not suitable for the surgery due to their young age and/or sub-optimal donor area! All hair transplant clinics are businesses needing constant money inflow in order to survive in the highly competitive market!
Clinics can use outdated techniques because they were accustomed to them, but may not be the most suitable for a particular type of patients.
Every clinic prefers to be always fully booked. Patients who should normally wait with the surgery (due to a very young age/not being on medication) could be advised to get the surgery asap because it suits the clinic.
It’s in the clinic’s interest to quote you less grafts than you need in order to come for another surgery 1 year later as prices per graft are generally higher if a smaller session is performed (more common for the US clinics)
On the other hand, it is in the clinic’s best interest to quote you a way higher number of grafts than you actually need (very common in Turkey, where the cost of labor is so low that transplanting 5000 grafts per day costs the clinic’s owner not significantly more than 1500 grafts). In today’s globally competing market this is a common strategy for creating a no-brainer (max grafts low price) offer in order to dismantle the US, UK or European hair transplant offers for good and make the client go to Turkey in hope for max. density and coverage possible in one session. This, however, often comes at the cost of a permanently over-harvested donor area.
