TLDR Methylene blue helps hair growth by protecting hair stem cells from stress.
The study explores methylene blue's (MB) protective effects on hair follicle stem cells (HFSCs) against oxidative and metabolic stress, enhancing hair regeneration. MB improves HFSC survival and function by reducing reactive oxygen species and activating the β-catenin signaling pathway, crucial for hair growth. It also synergizes with minoxidil, a common hair growth stimulant, to further enhance β-catenin activation. However, vitamins A and C do not enhance MB's effects and may reduce its benefits. While MB shows promise as a therapeutic agent for hair loss, the study lacks participant details, and further in vivo research is needed to confirm these findings and establish clinical dosing.
