Although cost is a big issue it should not necessarily be the deciding factor. Competence, medical quality/standards, patient care, artistic awareness are what you will remember as your result matures and over the following years, not the cost.
There will be some fluctuations in cost around the Europe and the world, some are simply down to running costs per country. For example, our Clinics in London and Malaga operate to the same standards of quality and care but Spain has slightly lower operating costs compared to the UK and we can offer this to our patients, with our doctors having worked in both Clinics from time to time.
It can go both ways, a massively inflated cost or hugely lower cost than the average should probably not be taken as an immediate upside but questioned as to why. How many procedures are being performed in a day, what role does the doctor play, are you being quoted hairs or follicular units. Is the cost dictated by the number of procedures, ie. it ´s more about numbers on chairs rather than the care and quality on a personal level.
No one in sound mind would deliberately put themselves in a compromising situation, and research is very important. Your choice of Clinic, regardless of country should be based on quality and having your well-being in mind.
