On occasion you do see great results from these 2500 euro "all in" jobs in Turkey. But they are so few and far between its a roll of the dice. The odds are certainly not in your favour.
Of course, there are many bad solutions like every country and I know that hair transplant is an all-important surgery. There are a zillion clinic in the world and they do hair transplant in different prices. But I think that after the good research, the clinic which gives an average price is a good clinic. If the price is minimum, then the using materials and hair transplant team can be bad. If the price is maximum, then the clinic does hair transplant only for making money.
