Nutrafol Launches Strand Serum to Combat Hair Breakage

NEW YORK, Sept. 30, 2026 /CourierPR/ -- Nutrafol, the leading dermatologist-recommended hair growth supplement brand, has expanded its comprehensive hair health approach with the launch of Strand Serum, the company’s first clinically tested, physician-formulated serum dedicated to strand health. This new innovation aims to strengthen and protect hair against breakage, addressing one of the most common concerns among people experiencing hair thinning.

Strand Serum is designed to deliver 6X stronger hair and reduce breakage by up to 83% over time, according to clinical testing. The serum also reduces split ends by 62% and achieves 85% frizz reduction for up to 72 hours. Additionally, it protects hair from heat damage up to 450°F, making it a versatile addition to any hair care routine.

The science behind Strand Serum starts with porosity, hair's ability to absorb and retain moisture. High-porosity hair has a lifted, damaged cuticle that leaves strands more vulnerable to breakage, frizz, dryness, and split ends. Strand Serum supports hair's porosity by sealing damaged, porous areas along the strand for smoother hair. This can lead to strengthened hair fibers, improving resilience to breakage and protecting visible length.

Strand Serum is powered by the following ingredients: - Milk Thistle Seed Extract to help strengthen the hair cortex - Wild Olive Extract derived from stem cells and helps hair feel soft and moisturized, while visibly sealing split ends - Hemisqualane, a sugarcane-derived silicone alternative, replenishes protective lipids and helps defend against breakage - Rosehip Fruit Extract, derived from the fruit of roses grown in Spain and full of vitamins, antioxidants, and fatty acids

Nutrafol prioritizes clinical rigor, evaluating 36 ingredient candidates across 54 formula iterations and 18 preclinical studies before assessing the final formula for efficacy and safety. The vegan formula is color-safe, extension-safe, and formulated without parabens, phthalates, silicones, sulfates, or synthetic fragrance. Consumer testing included the full range of hair types (1A, 4C), including chemically treated, color-treated, and chemically straightened hair.

Beginning today, Nutrafol subscribers can shop Strand Serum exclusively through the myNutrafol app ahead of its broader launch on October 6. Strand Serum will then be available on Nutrafol.com, through Nutrafol's expansive network of haircare and healthcare professionals, and on Amazon for $54 (30 mL/90-day supply).
