Strand-Strengthening Hair Serums

Nutrafol's Strand Serum Strengthens Hair from Cortex to Cuticle

Nutrafol is expanding its approach to hair health with Strand Serum, a physician-formulated treatment designed to protect existing growth from breakage. Its DualFusion Complex uses a water phase that penetrates the hair cortex alongside an oil phase that seals the cuticle, targeting damage from within and along the surface. The serum is designed to improve porosity, strengthen vulnerable fibers and protect against heat damage up to 450°F. Clinical testing also showed reductions in breakage and split ends over time.

The launch allows Nutrafol to address the hair journey beyond supplements and scalp care by adding strand protection to its portfolio. For the brand, this creates another complementary step that can encourage multi-product routines among existing customers. Subscriber-first access, followed by distribution through Nutrafol, Amazon, professionals and an Ulta Beauty-exclusive kit, also supports broader trial and cross-channel sales.
