What are cytokines?
Cytokines are small proteins involved in cell signaling that regulate immune responses, inflammation, and tissue repair throughout the body.
In the scalp, certain pro-inflammatory cytokines can disrupt the hair growth cycle and contribute to hair loss, particularly in autoimmune or inflammatory conditions.
Red light therapy may help balance cytokine activity by reducing inflammatory signaling and promoting a more favorable environment for healthy hair growth.
