Exosomes, such as those used in the Purasomes range, are microscopic, naturally occurring messenger particles derived from stem cells. In hair restoration treatments, these exosomes are applied to the scalp to deliver a concentrated blend of growth factors, peptides, and signaling molecules directly to the hair follicles. This bioactive communication helps “wake up” dormant follicles, reduce inflammation around the scalp, and support a healthier environment for hair growth. By stimulating cellular repair and encouraging the natural hair cycle, Purasomes exosomes can promote thicker, stronger, and more resilient hair over time. The treatment is typically used alongside microneedling or other scalp therapies to enhance absorption and maximise results, offering a modern, regenerative approach to improving hair density and overall scalp health.
