A $4.5 Million Bet on Biotech Hair Fibre
Biotech beauty start-up Ruka Hair has secured USD 4.5 million (approx. RM21.3 million) in fresh funding to scale its lab-grown hair extensions, signalling that investors see real commercial potential in biotech hair fibre. The round was co-led by Freedom Trail Capital and Henkel Ventures, joined by Big Issue Invest, Backed VC and several strategic angel investors, including Olympic sprinter Dina Asher-Smith. Co-founders Tendai Moyo and Ugo Agbai launched Ruka in 2020, building a brand around the needs of textured hair consumers with products spanning human hair extensions, wigs and styling essentials. This new capital is earmarked for expanding retail distribution, bolstering manufacturing capacity and supporting a planned 2026 entry into the US market. For investors, the appeal lies not only in Ruka’s community-led brand but in its proprietary collagen-based fibre platform, which promises a cleaner alternative to both human and plastic-based synthetic hair.
How Lab-Grown Collagen Protein Hair Works
Ruka’s flagship innovation, Synths 2, is a patent-pending, lab-grown fibre made from collagen protein designed to behave like real hair. Unlike conventional synthetic extensions that rely on plastic polymers, this biotech hair fibre is biodegradable and hypoallergenic, and is made without plastic or carcinogenic materials. The technology is engineered specifically for curls, coils and kinks, addressing a segment of the market often underserved by legacy extension materials. Ruka has also filed a patent for shape-memory fibre technology, aiming to create collagen protein hair that can hold styles, bounce back after manipulation and maintain its performance over time. Behind the scenes, the company is investing in research and development, toxicology studies and manufacturing processes, while emphasising customer education. The result is a new class of lab-grown hair extensions that seek to match the look, feel and styling versatility of natural hair without the ethical and environmental compromises.
Sustainable Hair Alternatives Amid Supply Chain Scrutiny
The rise of lab-grown hair extensions comes as the beauty industry faces mounting pressure over transparency and sustainability. Human hair sourcing has long been dogged by ethical questions and opaque supply chains, while plastic-heavy synthetic hair contributes to waste and can cause irritation for some wearers. Ruka’s collagen protein hair aims to navigate this trade-off by offering sustainable hair alternatives that prioritise safety and biodegradability. Co-founder Tendai Moyo emphasises that consumers should not have to choose between aesthetics, health and values, positioning Ruka as a brand that addresses all three. By situating itself at the intersection of material science and textured hair care, the company offers an example of how biotech can be used to redesign everyday beauty products. If successful, this model could encourage broader shifts away from resource-intensive or ethically complex materials in the wider hair extensions category.
Henkel Ventures and the Mainstreaming of Biotech Beauty
Henkel Ventures’ participation in Ruka’s funding round underscores how established conglomerates are increasingly treating biotech beauty as a strategic priority. Henkel, the group behind well-known hair brands like Schwarzkopf and Got2b, is bringing technical, safety and regulatory expertise to Ruka’s lab-grown hair platform. Investment principal Tobias Botenwerfer highlights Ruka’s disciplined execution and clear consumer focus, while Freedom Trail Capital frames the brand as a community-built business with the potential to reshape an entire category. This blend of venture capital and corporate backing suggests that lab-grown hair extensions are moving beyond niche experiment and into the realm of scalable innovation. The trend mirrors developments in other sectors, such as lab-grown meat in food, where biotech has begun to disrupt traditional supply chains. As standards and testing frameworks solidify, biotech hair fibre could become a foundation for future hair care and styling products.
From Early Adopters to Global Expansion
Ruka’s latest funding round is explicitly geared toward scaling its lab-grown hair extensions beyond early adopters and into mainstream retail channels. The company plans to ramp up production of Synths 2, support a 2026 push into the US and deepen its presence in global markets, building on existing placements at retailers such as Selfridges. Alongside its biotech hair fibre, Ruka is expanding a broader ecosystem of styling products and tools tailored to different curl patterns and textures, positioning itself as a category-defining brand for textured hair care. Freedom Trail Capital notes that Ruka has grown through an authentic community rather than viral hype, a factor investors see as critical for long-term resilience. As consumer awareness of sustainable hair alternatives grows, lab-grown collagen protein hair could transition from novelty to default choice, reshaping expectations around performance, ethics and environmental impact in the hair extensions space.
