Active Concepts has launched AC ExoRoot, an active ingredient designed to target ‘hair span’ - the biological foundation that supports the time hair stays healthy, resilient, and visibly vital.
By reframing hair care as a wellness ritual, hair has become a visible biomarker of internal balance and long-term health rather than a surface-level concern.
AC ExoRoot begins with Chlorella vulgaris, a resilient microalga known for its adaptive strength.
In nature, Chlorella absorbs sulfur from its surroundings to build the amino acids and antioxidants that sustain its vitality.
Through biotechnology, AC ExoRoot recreates this process under controlled, sulfur-rich conditions, enhancing the algae’s natural sulfur content and optimizing amino acid synthesis.
AC ExoRoot promotes hair longevity via the amino acid-rich biology of Chlorella vulgaris that supports key biological biomarkers that maintain scalp homeostasis and hair growth signaling.
It supports hair span by leveraging the sulfur-rich peptides from Chlorella vulgaris to support a prolonged hair growth cycle.
In addition, it helps scalp pro-ageing by supporting fibroblast function and extracellular matrix integrity to maintain long-term resilience.
“Hair growth sits largely outside cosmetic regulation, with true regrowth claims tightly restricted and largely confined to minoxidil,” said an Active Concepts spokeswoman.
“This leaves beauty brands boxed into a narrow choice: rely on a single drug pathway or avoid growth claims altogether, creating a biologically real yet commercially underserved space,” she added.
“AC ExoRoot transforms this limitation into opportunity by unlocking synergistic performance where minoxidil alone falls short.”
