The Disturbed Microbial Niches of Itchy Scalp

The researchers reported that platelet-rich plasma treatment increased hair growth in androgenic alopecia patients, potentially by altering scalp microbiota composition, including increased Cutibacterium and decreased Staphylococcus and Lawsonella.

This review discusses the role of cutaneous and intestinal microbiota in the development of alopecia areata, summarizing current literature without reporting new clinical results.

This study found that the scalp microbiome was more diverse in alopecia areata patients than in healthy controls, and distinctive microbial profiles may be linked to disease severity and prognosis.

This study found that men with androgenetic alopecia have different scalp biophysical characteristics in androgen-sensitive areas compared to non-sensitive areas and healthy controls.

This review highlights that scalp pruritus is a complex condition with various underlying causes, making it a challenge to diagnose and manage effectively. It emphasizes the need for comprehensive patient evaluation, history-taking, and personalized treatment strategies to address quality of life impacts.

This study observed that dandruff in Indian women is associated with a distinct scalp microbiome, including specific bacterial and unknown Malassezia species, with implications for nutrient homeostasis and cell-host adhesion pathways.

This paper proposes a systematic approach to evaluating scalp itch using the SCALLP acronym and highlights the importance of classifying cases based on the presence of dermatological lesions and hair loss, but it reports no new clinical findings.

This review discusses the neurobiology and proposed mechanisms of scalp itch, but it does not report new clinical findings, highlighting the need for further research in this area.
