dr erdogan koray

Dr. Koray Erdogan was born in 1968 in Bursa-Gemlik, Turkey.

After graduating in medicine from the University of Haccettepe, Ankara, Turkey, he attended the Thoracic Surgery School at the University of Marmara, Istanbul, and served in an Intensive Coronary Care Unit.

In 2001, he opened his own clinic in Istanbul, ASMED, together with his first assistant Dilek Cakir.

After practicing both Strip and FUE techniques, in 2004 he decided to focus exclusively on the second one.


In 2006, he developed his own grafts extraction FUE technique called “DES”.


Dr. Koray – The DES technique

DES, also called sequential technique, requires the surgeon to hold a punch in one hand and the tweezers in the other.

Incision and extraction are performed fastly using both hands. According to Dr. Koray, this technique allows to speed up the follicular units extraction while maintaining a great quality. Dr. Koray thinks that the use of the “DES” technique allows to reduce also grafts traumas and transection rates.

Dr. Koray performs incisions by using lateral slit technique, that allows, in his opinion, to better control the angle direction and reduce scalp traumas.


Dr. Koray uses the manual punch that guarantees, in his opinion, higher growth rates, better wound healing and reduces transection rates. It allows also to maintain the sensitivity needed to change punch direction, in case of follicle transection.

Dr. Koray recently introduced two important concepts: donor area homogenization and coverage value.

The first is referred to the fact that patients can get a similar density of the donor area on the the receiving one, thereby achieving a natural appearance, also and above all with short hair.


The coverage value is nothing but the ratio between hair number per square centimeter and the average caliber of the hair. It’s a useful indicator that allows us to understand how many extractions can be made. The extraction will be planned considering the current coverage value and what you would get after surgery.

Thanks to these advanced techniques and a specialized support team Dr. Koray is one of the FUE megasessions  international pioneers (with more than 5000 grafts implanted in a single intervention).

Dr. Koray is an active member of Bellicapelli since 2005.
