Abstract: The scalp microbiome has emerged as an important factor in maintaining cutaneous homeostasis and follicular health. Recent advances in genetic sequencing technologies have enabled the identification of a complex microbial community composed of bacteria, fungi, viruses, and mites that coexist in balance with the host. Alterations in this microbial composition, known as dysbiosis, have been associated with several dermatological diseases, including androgenetic alopecia, alopecia areata, and seborrheic dermatitis. This study aimed to review current scientific evidence regarding the influence of the scalp microbiome on alopecias, addressing pathophysiological mechanisms, microbial alterations observed in major hair disorders, and future therapeutic perspectives. A narrative literature review was conducted using PubMed, Scopus, and Web of Science databases between 2019 and 2026. The analyzed studies demonstrated that changes in microbial diversity may influence inflammatory, immunological, and metabolic processes related to hair growth. It is concluded that the microbiome represents a potential therapeutic target in modern trichology, although further studies are required to establish its clinical applicability.
