Microagulhamento como possível terapia capilar para pacientes com síndrome pós-Covid

Abstract

INTRODUCTION: Microneedling, a technique that uses fine needles to create microlesions in the skin, has been shown to be a therapeutic alternative for hair recovery in patients with post-COVID alopecia. Studies indicate that post-COVID syndrome can trigger hair loss, leading to the need for effective interventions. OBJECTIVES: The main objective of this study was to describe the protocols for the use of microneedling in the treatment of hair loss associated with post-COVID syndrome, as well as its advantages and disadvantages. METHODOLOGY: This study was developed as a descriptive and exploratory bibliographic review, with a qualitative approach in several virtual health databases with the descriptors: “microneedling”, “Post-COVID Syndrome”, “telogen effluvium”, “post covid hair loss”, “telogen effluvium” and “microneedling”, including articles in full, published in Portuguese and English, in the period between 2020 and 2024. RESULTS: The results showed that most of the studies reviewed reported significant improvements in hair density and health after microneedling treatment. The technique induces microlesions that promote a beneficial inflammatory response, stimulating blood circulation and cell regeneration in the scalp. Although the data suggest the efficacy of microneedling, the lack of adequate control groups in many studies limits the ability to generalize the results. FINAL CONSIDERATIONS: Microneedling has proven to be an effective and safe intervention for the treatment of alopecia related to post-COVID syndrome, contributing to hair revitalization and improving patients' quality of life. However, the final considerations highlight the need for further research, with larger samples and control protocols, to deepen understanding of the technique's mechanisms of action and its application in other hair health conditions. Only with more rigorous research will it be possible to establish clear guidelines for the use of microneedling as a robust and reliable therapy.
