Trichology

Trichology is the scientific study of the hair and scalp, encompassing structural biology, growth physiology, disease mechanisms, and therapeutic innovation. While often associated with cosmetic hair care, trichology is deeply rooted in dermatologic science and plays a critical role in diagnosing and managing hair and scalp disorders. As hair loss and scalp concerns continue to rise globally, trichology has become a prominent focus at every international Dermatology Conference, where research-driven insights guide evidence-based care. Closely associated with clinical hair and scalp science, this field integrates dermatology, endocrinology, immunology, and regenerative medicine to provide comprehensive evaluation and treatment.

This session explores the biology of the hair follicle as a dynamic mini-organ influenced by hormonal signaling, genetic predisposition, inflammatory pathways, and environmental triggers. Disruptions in the hair cycle—anagen, catagen, and telogen—can result in shedding, thinning, or structural fragility. Participants will examine how androgen sensitivity contributes to patterned hair loss and how autoimmune processes underlie alopecia areata.

Scalp health is equally important in trichology. Sebaceous activity, microbial balance, and barrier integrity influence follicular stability. Conditions such as seborrheic dermatitis, folliculitis, and scarring alopecia are evaluated through clinical examination and dermoscopic analysis.

Diagnostic approaches include hair pull testing, trichoscopic imaging, laboratory assessment of hormonal and nutritional status, and biopsy when scarring conditions are suspected. Understanding root causes allows clinicians to design targeted interventions rather than symptomatic treatment alone.

Therapeutic strategies range from topical growth stimulants and systemic medications to regenerative approaches such as platelet-rich plasma and low-level laser therapy. Nutritional optimization and stress management are recognized as supportive components of holistic trichologic care.

Emerging research into stem cell activation and follicular regeneration continues to expand therapeutic potential. By combining scientific rigor with individualized planning, trichology empowers dermatologists to restore scalp health, preserve follicular integrity, and improve patient confidence.
