Do exosomes help create new hair follicles or does it just put thinning hair into anagen phase again?

Exosomes primarily help put thinning hair back into the anagen phase, promoting hair growth and thickening existing hair rather than creating new hair follicles. However, based on my experience, combining exosomes with PRF, PDO threads, and low-level laser therapy offers the best chances to stimulate new hair follicles and promote hair growth.

Exosomes stimulate existing follicular and epidermal  cells through intercellular signaling. This can induce follicles into the anagen stage as well as transform dormant stem cells into new follicular units. Exosomes have shown some effect on bald areas. However, The result is not uniform and seems to be dose-related. Not all Exosomes have the same composition and functional ability. It's important to pick a provider that uses a well-documented, safe product.

There is no evidence that Exosomes can stimulate new growth in a Class 7 patient. The hair follicles in a bald man are largely dormant.
