A New Approach to Hair Biology

8T3 Essentials Hair Serum is built on more than 25 years of research into soluble CD83 (sCD83), a naturally occurring glycoprotein studied for its role in immune signaling and regenerative processes.
Supported by more than 60 peer-reviewed publications, this research forms the scientific foundation for a topical approach designed to support the scalp environment where hair growth begins.

  • A New Approach to Hair Biology

    8T3 Essentials Hair Serum is built on more than 25 years of research into soluble CD83 (sCD83), a naturally occurring glycoprotein studied for its role in immune signaling and regenerative processes.

    Supported by more than 60 peer-reviewed publications, this research forms the scientific foundation for a topical approach designed to support the scalp environment where hair growth begins.

  • Understanding the Role of sCD83

    Research led by Prof. Dr. Alexander Steinkasserer, a leading immunologist in CD83 biology, has explored how sCD83 interacts with the biological environment surrounding the hair follicle.

    This work focuses on pathways involved in:

    • Immune signaling
    • Regenerative activity
    • Signaling and regenerative potential of the scalp

    Together, these factors help shape the environment in which hair follicles function and may influence hair density over time.

  • The Origins of CD83 Research

    The study of soluble CD83 (sCD83) did not originate in hair biology. For more than 20 years, research has focused on its role in dendritic cells and broader cellular signaling processes, particularly in contexts where immune balance is disrupted. Early work explored how the two CD83 molecules (mCD83 and sCD83) regulate immune-related environments, how they induce immune tolerance as well as resolution of inflammation, which has been the subject of extensive laboratory and translational research.

  • Notably, peer-reviewed studies have examined CD83 in areas such as cellular response coordination and tissue-level signaling, contributing to a growing body of knowledge around its broader biological relevance. (see e.g. Royzman et al., 2022 Front. Immunol.; Sinner et.al. 2023, Nat. Commun.; Royzman et al., 2025, Adv. Exp. Med Biol.; Hollard et al., 2026 Wound Repair Regen.)

    This foundational research provides context for its continued study in adjacent biological systems, including the scalp environment.

  • Implications for Hair Thinning

    Hair thinning is not driven by a single mechanism.

    While hormones play a role, the condition of the scalp environment—including inflammation and cellular signaling—also contributes to how hair follicles behave.

    Research on sCD83 has explored both inflammation-associated and non-hormonal pathways, supporting a broader, non-systemic approach to hair biology.

  • Preclinical Research and Early Observations

    Findings from preclinical models of androgenetic alopecia (AGA) and alopecia areata (AA) have demonstrated activity across multiple pathways relevant to the hair follicle environment.


    In early observational settings, topical application has been associated with improvements in measures including hair count, density, and thickness.

    Controlled clinical research is ongoing. In early human and internal observations, twice-weekly use over 3 to 4 months was associated with an average 44% improvement.

  • From Immunology to Follicular Observation

    The connection between sCD83 and hair follicle biology emerged during preclinical research not originally focused on hair. Researchers observed changes in the local environment, including improved tissue quality and wound repair. Interestingly, the observed increase in the number of hair follicles was a serendipitous finding.

    This unexpected discovery prompted further investigation into how the same underlying biological pathways might relate to the scalp. While research is ongoing, these observations helped extend a well-established area of study into a new application, informing the development of a topical approach centered on the scalp environment and hair growth.

  • Preclinical Insights

    In laboratory and preclinical settings, research on sCD83 has evaluated:

    • Localized distribution near follicular structures
    • Interaction with immune signaling pathways
    • Regenerative processes relevant to the follicular environment

    These findings continue to inform ongoing research and formulation development.

  • A Targeted, Non-Systemic Approach

    8T3 Essentials is designed for localized, topical application directly to the scalp. This approach focuses on supporting the biological environment at the hair follicle—where thinning may begin—without systemic exposure.

  • By aligning with research into inflammation-associated and non-hormonal pathways, it represents a different way to approach scalp health and hair density.
