Should You Be Turning to Exosomes for Hair Growth?

June 9, 2026

I am always looking for ways to grow thicker, healthier hair. On top of dermarolling my hairline and wearing red-light hats, there’s one skin-care ingredient that’s quietly making the crossover to hair care that I can’t stop thinking about: exosomes.

One of the buzziest regenerative skin-care ingredients, exosomes are what Ronda Farah, MD, associate professor in the department of dermatology at the University of Minnesota, describes as “communication vehicles” in our bodies. “They are similar to tiny cars delivering messages between cells,” Farah says. “Exosomes can contain proteins, DNA, RNA, and other signaling molecules that may influence how cells behave.”

And if something can help with our skin health, then it must also be good for our hair. Hair care is skin care, after all, and when you take care of your scalp, you give your hair the healthiest environment to thrive. At least that’s the train of thought when it comes to exosome hair therapy. “The buzz with exosomes is that it carries a much larger and more potent payload,” says Raphael Gonzalez, PhD, scientific adviser at Exora. “This means that payload can be multiple factors that can serve the hair well.”
