A narrative review on subcutaneous injection components used for alopecia
1Department of Acupucture and Moxibustion, College of Korean Medicine Kyung Hee University, Kyung Hee University Hospital at Gangdong, Seoul, South Korea.
Background:
Studies reporting the development and effectiveness of topical agents for alopecia are available. However, it was difficult to demonstrate a direct advantage of subcutaneous injection rather than topical application. Since existing articles lack information, future studies are needed to solve these problems and to narrow the knowledge gap.
Aims:
Present article is aimed to review of the possible materials used in subcutaneous injection for alopecia with a hope for better guiding the analytic application and further evaluating the effective component for alopecia management.
Methods:
A wide range of clinical articles was retrieved using electronic databases to determine the possible components used in subcutaneous injection and their potential mechanism of action.
Results:
Eight components from 19 articles were found to be used for alopecia via subcutaneous administration.
Conclusions:
The current study illuminated the curative effects of possible substances and discussed the efficacy of subcutaneous injections.
