Fiabila brings nail expertise to hair care with dual-use keratin serum

Fiabila is extending its over 50 years of nail care expertise to hair care with the launch of its keratin-powered Nail’N’Hair Milky Serum. The multi-use formula leverages Fiabila’s experience with nail keratin care, applying it to hair fibers.

The launch is said to reflect the growing convergence of hair and nail care. Following broader trends in the personal care industry, both segments are increasingly “skinified,” applying principles of skin care to their respective beauty categories.

Personal Care Insights sits down with Candice Jagut, marketing and innovation director at Fiabila, to discuss how the “skinification” trend has informed the serum’s utilization of keratin, the serum’s individual benefits, and its dual-use packaging.

Keratin for hair and nails 

The Nail’N’Hair Milky Serum was created to tap the growing “skinification” and “scientification” trends.

Alongside using skin care principles for other categories, personal care is also seeing heightened demand for clinical backing and scientific credibility.

“‘Skinification’ encourages the transfer of recognized care ingredients across beauty categories, and ‘scientification’ leverages Fiabila’s longstanding expertise in keratin-based nail care,” says Jagut.

“As both nails and hair are keratin-rich structures, the objective was to create a single formula suitable for both uses while maintaining a lightweight milky texture and a convenient application gesture.”

The dual-purpose serum also caters to the demand for clean beauty. According to Fiabila, it is formulated with 96% naturally derived ingredients and uses ceramides, omega fatty acids, marine algae amino-peptides, and argan oil for nails, cuticles, and hair.

Jagut tells us that the serum was developed with consumer feedback. She says the participants communicated 100% overall satisfaction, 93% softer and smoother nails and cuticles, and 93% less brittle hair after two weeks of use.

Jagut clarifies that the reported benefits reflect the efficacy of the Fiabila formula and that results would need to be reassessed on any customized brand version.

Packaging ergonomy

The dual-use formula targets keratin-rich hair and nails.

The Nail’N’Hair Milky Serum is packaged in a compact, travel-friendly, dual-use, airless pack made from recyclable polypropylene to help protect the formula.

“The packaging was designed as a complement to the formula and its dual-use positioning for nails and hair,” says Jagut. “It ensures precise dispensing, a high product dispensing rate, and reduced product waste. The integrated applicator enables intuitive, direct application on nails, cuticles, and hair.”

Industry-wide “skinification”

The “skinification” trend has been taking over hair, nails, and even oral care. Consumers are seeking skin care level efficacy in their products, leading brands to turn to skin care practices for inspiration.

Personal Care Insights spoke to Berg+Schmidt at In-cosmetics Global 2026 about the BergaCare Hair Care range, which includes scientifically validated actives and functional materials designed to offer “skinified” care from the scalp to the ends of the hair fiber.

Berg+Schmidt stated that the shift toward “skinification” reflects a broader market evolution. Consumers are increasingly viewing their hair and scalp health as an extension of their skin care routine, seeking out ingredients that offer long-term benefits rather than temporary aesthetic fixes.

Earlier this week, we sat down with the CEO and co-founder of Ossa Care, Dr. Camille Zenobia, to discuss “skinification” in oral care. Ossa Care’s portfolio focuses on oral health, gum microbiomes, and oral mucosa. She told us “skinified” oral care focuses on supporting and restoring mouth microbiomes rather than taking a bacterial attack approach. We also discussed the benefits of traditional skin care active ingredients in supporting tissue and periodontal aging.

“We’re not competing with heritage toothpaste; we are replacing it by introducing a category that didn’t exist: mucosal wellness for the mouth,” said Zenobia.
