Exosomes are extracellular vesicles that carry bioactive molecules, including growth factors, proteins, lipids, and mRNA, which play a crucial role in intercellular communication and tissue regeneration. They are naturally produced by cells and act as a delivery system to transfer these bioactive molecules to target cells.

​

Exosome hair treatments work by creating a regenerative environment that accelerates follicle activation, promotes stem cell proliferation, reduces inflammation, and delivers growth-promoting factors to the scalp. By stimulating the dermal papilla, dermal sheath, and hair follicle stem cells, exosomes enhance hair follicle health and stimulate the growth of thicker, stronger hair. This results in improved hair density, reduced hair loss, and a more youthful appearance of the scalp.

​

Exosomes facilitate hair restoration through their ability to deliver critical growth factors, activate stem cells, modulate gene expression, reduce inflammation, and extend the anagen phase of the hair cycle.

​

Exosomes' Impact on Hair Cycle Phases:

​

• Anagen Phase (Growth): Exosomes promote the activation and maintenance of hair follicles in the anagen phase, which is the active growth phase. Growth factors in exosomes such as FGF, VEGF, and IGF stimulate follicular cells to proliferate and increase hair shaft production.

​

• Catagen Phase (Regression): Exosomes help prevent the premature onset of the catagen phase, where hair growth ceases, and the follicle begins to shrink. By modulating the dermal papilla and activating growth pathways, exosomes keep hair follicles in the anagen phase longer, reducing hair shedding.

​

• Telogen Phase (Resting): The telogen phase, or resting phase, can last for several weeks to months. Exosomes help to shorten the telogen phase by reactivating dormant hair follicles and promoting a shift back to the anagen phase, encouraging new hair growth.

The initial application of exosomes will be done via microneedling. After microneedling creates the tiny channels in the scalp, the exosome serum applied enhance the healing process. The exosomes enter these micro-channels and penetrate deeper into the scalp, promoting faster recovery, better absorption, and more efficient tissue repair.
