Exosomes are small, extracellular vesicles derived from stem cells, rich in proteins, lipids, and genetic material essential for cellular communication and repair. In hair restoration, exosomes act as powerful messengers, delivering signals that rejuvenate the scalp environment, stimulate hair follicle activity, and promote the natural hair growth cycle. This non-surgical approach reactivates dormant follicles, supports the regeneration of active ones, and fosters a healthier scalp, making it an advanced, effective solution for combating hair thinning and loss.
