A latest study discovered that a healthy immune system can stimulate the hair growth. They found the linked between the immune system cells, macrophage and the skin stem cells. The study was done by a team of scientists from the Spanish National Cancer Research Centre.
The study author Mirna Perez-Moreno says that earlier, in their previous study, they identified the activation phase of resting skin stem cells. This is actually the phase when hair growth occurs.
After their previous study, they conducted this new study separately on some mice, and observed that the macrophage cells are linked in the activation of hair follicle stem cells in the healthy skin.
The author Mirna Perez-Moreno mentioned that she and her team tested on the other cells of the immune system to rule out if they are involved in the hair growth.
