Ruka’s USD 4.5 Million Funding Round Puts Lab-Grown Hair in the Spotlight
Biotech beauty brand Ruka Hair has secured USD 4.5 million (approx. RM20.7 million) in new funding, a clear sign that lab-grown hair extensions are moving from niche experiment to serious category contender. The round was co-led by Freedom Trail Capital and Henkel Ventures, with additional backing from Big Issue Invest, Backed VC and several strategic angel investors, including athlete Dina Asher-Smith. Founded in 2020 by Tendai Moyo and Ugo Agbai, Ruka has built a loyal community by addressing long-standing concerns over how traditional hair extensions are sourced and how safe they are to wear. This fresh capital will support expansion of its lab-grown hair products, bringing biotech hair fibre into more salons, retailers and online carts worldwide. For consumers, that means more choice beyond synthetic plastics or human hair whose origins can be hard to verify.

Inside Synths 2: The Collagen Protein Fibre Rethinking Extensions
At the core of Ruka’s innovation is Synths 2, a patent-pending lab-grown hair extension material made from collagen protein fibre. Unlike traditional synthetic hair, which is usually plastic-based, this biotech hair fibre is engineered to look, feel and perform like real hair while remaining biodegradable and free from plastic and carcinogens. The fibre is also hypoallergenic, a major advantage for wearers who experience irritation from conventional braiding hair. Designed for curls, coils and kinks, Synths 2 aims to mirror the texture and movement of textured hair, offering a more natural blend and styling experience. Ruka has also filed a patent for shape memory fibre technology, which could help styles hold their form for longer while still moving like natural strands. In practical terms, collagen protein hair points to a new era of lab-grown hair extensions that prioritise both performance and wearer comfort.
Why Biotech Hair Fibre Matters for Sustainability and Ethics
Lab-grown hair extensions like Ruka’s Synths 2 respond to growing demand for sustainable hair alternatives that do not compromise ethics or quality. Traditional human hair extensions raise questions around sourcing transparency, labour conditions and supply chain traceability. Plastic-based synthetic hair, while more accessible, typically relies on petrochemicals and can shed microplastics, adding to environmental concerns. By contrast, Ruka’s collagen-based biotech hair fibre is biodegradable and produced in a controlled environment, reducing reliance on opaque supply chains and plastic-heavy materials. The brand positions its extensions as safer and more consistent in quality, with toxicology and performance testing built into development. While no single product solves every sustainability challenge, biotech-driven collagen protein hair shows how innovation can reduce some of the trade-offs between style, ethics and environmental impact—especially for consumers who wear protective styles frequently and in high volumes.
Big Beauty’s Backing Signals Market Confidence in Lab-Grown Solutions
Henkel Ventures’ participation in Ruka’s funding round is more than a financial boost; it is a signal that major beauty industry players see biotech hair as a serious long-term bet. Partnering with Henkel gives Ruka access to deeper technical and safety expertise, which is crucial as the category pushes toward clearer standards and rigorous testing. Freedom Trail Capital highlights Ruka as a brand that grew through community, not hype, and now has the potential to reshape an entire category through biotechnology. With Ruka already stocked in prestige retailers such as Selfridges and preparing for broader global roll-out, this investment accelerates lab-grown hair extensions from early adopter status toward mainstream visibility. For everyday consumers, the message is clear: biotech hair fibre is no longer a futuristic concept, but a credible alternative that large investors expect to become a staple in textured hair care.
What Ruka’s Expansion Means for Everyday Hair Routines
The newly secured funding will help Ruka scale production of its lab-grown fibre platform and expand internationally, making biotech hair products easier to access for more people. Beyond braiding hair, the company is building a broader ecosystem: from hair gels to hair perfumes, its styling products are formulated to balance hold, shine and hair health, complementing its collagen protein hair extensions. As Synths 2 becomes more widely available, consumers who rely on protective styles will gain another option alongside human hair and plastic-based synthetic bundles. Over time, increased production could bring more textures, colours and style-specific fibres designed to better support curls, coils and kinks. While pricing, availability and salon adoption will ultimately shape how fast the market shifts, Ruka’s latest move suggests that lab-grown hair extensions are set to play an increasingly visible role in everyday hair routines.
