Medical Specialty
The official medical specialty is recorded separately from hair transplantation. “Hair Transplant Specialist” is not used as a medical specialty; it describes a clinical focus or role, not a Turkish residency branch.
Credential Membership
No accepted hair-restoration credential membership has yet been verified for this profile.
Techniques
Technique labels are tracked separately from medical specialty and operative responsibility. A check mark identifies a technique verified in the current research record; a question mark means it has not yet been verified for this doctor.
Doctor Involvement
These five stages are tracked separately. A check mark means the doctor’s personal involvement is verified; a question mark means the public evidence is not yet sufficient to confirm that stage.
Procedures
Procedure types are shown only where the doctor's current record supports them. Unverified beard, eyebrow or revision work remains marked with a question mark rather than being inferred from clinic-wide services.
Biography and Medical Education
Dr. Öykü Maraşoğlu Çelen is an Istanbul-based Dermatology specialist with published work in medical and cosmetic dermatology and hair-transplant planning. Historical ISHRS directories linked her to Skin Health Turkey, while recent academic records describe her as a private physician in Istanbul.
Çelen completed medical education at Istanbul University Istanbul Faculty of Medicine and then undertook a five-year Dermatology residency at Istanbul University Cerrahpaşa Faculty of Medicine. The source workbook records medical graduation in 2003; the residency pathway and specialist title are independently corroborated by her professional media and publications.
Her academic record includes peer-reviewed dermatology work and congress participation. A 2023 special issue on hair transplantation assigns her the chapter on candidate selection and preoperative planning, confirming continuing subject-matter work in hair restoration.
ISHRS membership directories from 2018 through 2020 list I. Oyku Celen, MD as an Associate Member at Skin Health Turkey in Istanbul. Her name was not found in the reviewed 2024 directory, so the historical affiliation is retained in editorial data but is not displayed as a current Credential Membership.
Education and career chronology
Current practice and evidence context
Published material establishes specialist expertise in dermatology and hair-transplant candidate selection and planning. It does not document which operative stages she personally performs in current cases, so supervision alone is verified and all four operative-stage fields remain unverified.
