A New Approach to Hair Biology

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
Unlike many hair care formulas that rely on hormone-related ingredients, 8T3 Essentials is hormone-free by design. It's formulated based on research into scalp condition and supports the look and feel of healthier, fuller-appearing hair over time.

Preclinical Research and Early Observations
Preclinical and early-stage research on sCD83 has explored its relationship to scalp condition. This research informed the formulation of 8T3 Essentials for the US market as a cosmetic product.
From Immunology to Follicular Observation
This research into sCD83 and scalp condition informed the development of a topical formulation designed for the look and feel of fuller-appearing hair.
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. 8T3 Essentials is designed for localized, topical application directly to the scalp, 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.
