The Treatment
Polynucleotides for Hair
Polynucleotides for hair are a regenerative scalp injection that works on the tissue quality of the scalp, the environment in which hair grows. They do not regrow lost follicles, but they support the conditions follicles need to remain healthy: hydration, circulation, and resilient tissue.
Hair density is not only about the follicles, it is about the tissue they sit in. A thinning scalp environment cannot support strong hair, no matter how good the genetics. Polynucleotides are one of the few treatments that address the scalp at this biological level, making them a foundational layer within a regenerative hair plan.

About
What it is, how it works.
How it works
Tiny amounts of polynucleotide solution are placed just beneath the scalp's surface across the area being treated. Over the following weeks, they support the scalp's own repair cells, helping the local environment around the follicle behave more like younger, healthier tissue.
Why it matters
Hair density is not only about the follicles, it is about the tissue they sit in. A thinning scalp environment cannot support strong hair, no matter how good the genetics. Polynucleotides are one of the few treatments that address the scalp at this biological level, making them a foundational layer within a regenerative hair plan.
