The Immune System’s Secret Role in Hair Growth
Your immune system isn’t just a defense force—it’s also a repair team. Regulatory T cells (T-regs) have been proven to activate hair follicle stem cells by releasing special growth signals like TGF-beta3. These signals tell stem cells to wake up and rebuild the follicle. When T-regs move freely and function properly, hair growth increases. But stress, poor health, and inflammation can limit their activity. Supporting immunity through nutrition, sleep, and scalp health helps T-regs do their regenerative job.
