Clinical Expertise

Dermatology & Venereology

The clinical practice of Dr. Apostolos Karalexis covers a wide spectrum of dermatological and venereological conditions.

His long-standing hospital and private-practice experience allows him to evaluate both common and more complex dermatological problems, with an emphasis on accurate diagnosis, individualized treatment and long-term patient follow-up.

His background in military and hospital medicine has also provided substantial experience in managing diverse clinical presentations across different age groups and patient profiles.

Hair Loss & Scalp Disorders

Hair and scalp disorders represent one of the main fields of interest in Dr. Apostolos Karalexis’ clinical practice.

With more than two decades of experience in Dermatology, he evaluates different forms of hair loss, including androgenetic alopecia and other conditions that may affect hair density and scalp health.

An important part of the diagnostic process is identifying the underlying cause of hair loss before choosing the appropriate treatment strategy.

Depending on the individual case, management may involve medical treatment, supportive therapies or hair transplantation when surgical restoration is considered appropriate.

Hair Transplantation

Hair transplantation is one of the areas in which Dr. Apostolos Karalexis has developed particular expertise.

His international training and extensive experience in hair disorders have allowed him to refine his approach to hair restoration, focusing not only on improving density but also on creating a result that respects the patient’s facial proportions, natural hairline and existing hair pattern.

Careful planning is particularly important in modern hair transplantation. The position and shape of the hairline, the distribution of available donor follicles and the long-term progression of hair loss must all be considered before the procedure.

For this reason, Dr. Karalexis places particular emphasis on individualized surgical planning rather than applying the same design or graft distribution to every patient.

His goal is to achieve a balanced and natural-looking result while preserving the donor area and taking into account the potential evolution of hair loss over time.

Dermatologic Surgery

Dr. Apostolos Karalexis received advanced postgraduate training in Dermatologic Surgery at Tulane University in the United States.

This additional training expanded his experience in procedural Dermatology and provided exposure to modern surgical techniques within the specialty.

Dermatologic Surgery remains an important part of his broader professional profile and complements his clinical expertise in both medical Dermatology and hair restoration.

A defining element of Dr. Apostolos Karalexis’ professional development has been his decision to pursue further education outside Greece.

Following his initial dermatological training, he continued his specialization at Tulane University, New Orleans, Louisiana, where he focused on Dermatologic Surgery.

The experience gained in the United States allowed him to become familiar with different clinical protocols, surgical approaches and developments in contemporary Dermatology.

International education has remained an important element of his career, which is also reflected in his continuing participation in scientific meetings and professional organizations outside Greece.

An Individualized Approach to Hair Restoration

Successful hair restoration requires more than the technical placement of hair follicles. Every patient presents a different degree and pattern of hair loss, donor-area capacity, hair characteristics and expectations regarding the final appearance.

For this reason, Dr. Apostolos Karalexis approaches hair transplantation as an individualized medical and aesthetic procedure.

The design of the hairline, the number and distribution of grafts and the management of the donor area must be planned according to the patient’s existing anatomy and the expected progression of hair loss.

This personalized approach aims to create a result that appears harmonious rather than artificial, while maintaining options for future treatment if hair loss continues.
