Active Concepts reframes hair care around longevity with “hairspan” ingredient launch

Active Concepts has released a longevity ingredient targeting “hairspan,” a term that describes the biological foundation that supports hair’s vitality. The personal care ingredients company is reframing hair care as a wellness ritual. 

AC ExoRoot supports the time hair stays healthy and resilient. Active Concepts outlines that hair has become a visible biomarker of internal balance and long-term health rather than a surface-level concern. The new ingredient aims to offer more than growth claims and instead “finally gives brands something meaningful to say beyond them.” 

“For decades, success in hair care has been defined by visible regrowth and the appearance of hair. Hairspan challenges that by shifting the focus to the long-term health and resilience of the scalp and follicle. When longevity becomes the goal, success is measured by whether the biological environment that supports hair is being preserved over time, not just short-term changes in appearance,” Bernice Pimentel, technical marketing specialist at Active Concepts, tells Personal Care Insights. 

“This reframing gives brands a more credible way to innovate and helps consumers think of hair care as a wellness ritual, rather than a reaction once loss becomes visible.”

Using microalgae for hair

AC ExoRoot extends hair longevity by supplementing scalp biology, an approach Active Concepts calls the next frontier of hair care. 

AC ExoRoot begins with Chlorella vulgaris, a resilient microalgae 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.Hair care is shifting toward longevity framing. 

Encapsulated within protein-stabilized vesicles, these sulfur-rich enhanced biomolecules form a complete biochemical network designed to restore balance and extend the “hairspan.” 

Within the follicle, sulfur has been known to reinforce keratin structure and antioxidant defenses, while amino acids can promote collagen synthesis to help maintain scalp firmness and extracellular matrix integrity. By supporting the scalp microenvironment, AC ExoRoot helps prolong the anagen phase, the active growth stage of the hair cycle, and preserve the hair’s natural rhythm of regeneration. 

The process is also developed through a closed-loop, renewable process.

Going beyond the limits

Hair growth sits largely outside the bounds of cosmetic regulation, with substantiated regrowth claims tightly restricted to minoxidil. The ingredient is a widely used, US FDA-approved over-the-counter medication for male and female pattern hair loss, supported by decades of clinical research demonstrating its ability to stimulate hair regrowth.

That evidentiary dominance, however, has narrowed the field for beauty brands, leaving a biologically credible but commercially underserved space with few ingredients meeting the regulatory and scientific thresholds for regrowth claims. 

“Hair growth is one of the most tightly regulated areas in beauty, leaving brands with two constrained options: rely on a single drug-based pathway centered on minoxidil, or avoid growth claims altogether. In both cases, meaningful differentiation is limited, leaving minoxidil-based brands competing within the same mechanism and non-drug brands largely excluded from the growth conversation,” says Pimentel.

Active Concepts says AC ExoRoot transforms this limitation into an opportunity by unlocking synergistic performance that minoxidil alone cannot deliver. Hairspan reframes scalp health as long-term wellness. 

“AC ExoRoot creates a third path through hairspan by focusing on follicle longevity and scalp resilience rather than regrowth. By improving follicle signal receptivity, it works synergistically with minoxidil to support more robust biological responses, while also giving non-drug brands a credible, longevity-driven way to participate in the hair growth conversation without making regrowth claims,” explains Pimentel.

Hair care longevity

Longevity has shifted hair care from a problem-reacted-to into a practice that Active Concepts commits to. 

“When we start thinking about hair through that lens, the conversation moves away from fear of loss and toward preservation, intention, and long-term care,” says Pimentel.

She continues that longevity reframes aging as something for beauty companies to care for rather than fight against. In hair care, that mindset leads to a focus on preserving hairspan rather than chasing short-term results.

“Right now, hair care is still largely driven by quick wins and visible change. Over the next five to 10 years, I think product development and consumer expectations will move toward more holistic, ritual-driven approaches that support the biological markers of hair aging, like cellular senescence, inflammaging, oxidative stress, growth signaling, and hair shaft elongation. The real measure of success won’t be overnight change, but how well hair ages alongside us,” Pimentel concludes.
