The Science While human exosomes are being studied for their regenerative properties and show promise for stimulating new hair growth, their therapeutic use is limited by sourcing, purity, safety, and regulatory concerns.


The Nutrafol innovation team has overcome these limitations with exosomes from a botanical source. Nutrafol engineered a method for isolating Plant-Derived Exosome-like Vesicles (PDEVs) from the seeds of the same Ashwagandha plant used in Nutrafol Hair Growth Nutraceuticals to produce Ashwagandha Seed Exosomes.


Of all of its parts, the seeds of the Ashwagandha plant (Withania somnifera) are the most potent source of plant exosomes, which signal the plant to grow. These novel Ashwagandha Seed Exosomes deliver activated, bio-compatible plant material topically to help promote cell renewal on the scalp. Nutrafol is the only hair serum with this patent-pending and proprietary technology.

Growth Activator pairs Ashwagandha Exosome technology with clinically effective botanical extracts that include Green Tea and Pea Sprouts, plus Sea Buckthorn and Moringa to nourish the scalp, minimize visible breakage, and activate thicker-looking, stronger-feeling hair.



In safety studies3 the daily application of this hair serum formulated with Ashwagandha Exosomes was very well tolerated and showed no irritation, sensitization, or signs of intolerance.
