Hair follicle stem cells are cells that live in hair follicles for a long time and produce hair for us for life  Hair follicle stem cells absorb glucose from the blood and undergo metabolism, and glucose becomes pyruvate  A part of these pyruvate is transported by the cell into the mitochondria  In the mitochondria, pyruvate is used  Further metabolism can provide energy for cells  Another part of pyruvate will undergo subsequent changes in the cells to produce new metabolites-lactic acid, which can activate hair follicle stem cells and make hair grow faster
Lactic acid provided by drugs can directly act on hair follicle stem cells
 According to this, researchers have It is believed that increasing the content of lactic acid through drugs can treat hair loss
