FSS Vegan Keratin OS

FSS Vegan Keratin OS is a next-generation, oil-soluble keratin alternative designed to deliver the performance of hydrolyzed animal keratin with the sustainability and ethics of plant-based innovation. This active is created through the enzymatic hydrolysis of chickpea, lentil, and quinoa proteins, fermented using Lactobacillus to create low molecular weight oligopeptides (~1 kDa) that effectively penetrate and condition the hair shaft.

Keratin makes up over 90% of the hair fiber, but its large molecular size limits direct delivery in conventional treatments. By mimicking keratin’s key amino acids — such as cysteine, methionine, lysine, and glutamic acid — and dispersing them in a nourishing apricot oil base, FSS Vegan Keratin OS helps replenish the hair’s hydro-lipid layer, reduce breakage, restore shine, and protect against styling or environmental damage.

Unlike standard hydrolysis processes, the fermentation-based hydrolysis used here is mild, eco-friendly, and traceable, resulting in a cleaner, more sustainable peptide profile that supports both hair fiber integrity and scalp health.

MADE OF:

FSS Vegan Keratin OS is composed of hydrolyzed quinoa, chickpea, and lentil peptides, created via plant fermentation, and delivered in apricot kernel oil. It is non-GMO, gluten-free, vegan, and ideal for use in oil-phase or anhydrous hair care systems.

Scientifically Proven:

💧 Hair Hydration Power: Gravimetric analysis confirmed that FSS Vegan Keratin OS retains moisture in hair strands comparably to animal-derived keratin. It acts as an occlusive, forming a protective barrier that prevents water evaporation — keeping hair hydrated and healthier over time.

🧪 Transepidermal Water Loss Reduction: In a 24-hour TEWL study, FSS Vegan Keratin OS significantly reduced water loss from the skin. After just 1 hour, it decreased TEWL by 46.93%, outperforming the base lotion, which only showed a 12.98% reduction. After 24 hours, TEWL was lowered by 39.55% compared to the base lotion and by 39.05% versus the untreated control — confirming its barrier-reinforcing properties.

🌿 Enhanced Moisturization: A moisturization assay demonstrated that FSS Vegan Keratin OS consistently outperformed both base lotion and untreated controls. After 8 hours, skin moisture increased by 48.00%, compared to 36.62% with the base lotion. This effect continued through 24 hours, with a 17.91% increase in moisture compared to untreated skin.

💆‍♀️ Salon-Tested Hair Benefits: In a half-head study, shampoo containing 2.0% FSS Vegan Keratin OS improved cleansing, smoothing, and wet combability. When used in conditioner, it enhanced smoothing, dry and wet combability, anti-frizz, overall feel, shine, and hydration — showing noticeable improvements over the control.

🧴 Cleansing & Hydration in One: In a cleansing balm study, 5.0% FSS Vegan Keratin OS improved product efficacy by increasing cleansing performance while also providing added hydration to the skin. This dual function supports its use as a moisture-boosting ingredient in oil-based cleansers.
