The science of protein in Nexxus’ new thickening, anti-breakage range

Protein science advancements now address numerous hair concerns, with the latest focus on fine, fragile strands. This is key for those looking to thicken hair.

Having fine hair often means struggling with styles that lack density and are prone to breakage, leading to volume loss. NEXXUS addresses this by using the power of protein for hair repair and damage prevention. Since hair is 90% keratin, a fibrous protein, replenishing it in strands that have lost protein from heat or environmental damage is a logical solution. However, effective treatment requires more than just any standard protein application.

Key takeaways

• Protein is the foundation: Since hair is 90% protein, replenishing it is a direct way to repair damage and fortify fine, fragile strands against breakage.
• Arginine strengthens the core: This specific amino acid delivers superior strengthening benefits to the weaker inner core of fine hair, effectively reducing breakage.
• Instant thickness is achievable: Advanced densifying technology creates weightless micro-bonds between hair strands, resulting in visibly thicker hair from the first use.
• A full system maximizes results: Using a shampoo, conditioner, and root-lifting spray together provides comprehensive care for stronger, fuller-looking hair.

The best protein for fine hair

The NEXXUS Unbreakable Care Range was specifically formulated for fine and fragile hair, which is ten times more prone to breakage due to a smaller inner core. Through protein analysis, NEXXUS scientists found that the amino acid arginine provides nearly double the core-strengthening benefits. The NEXXUS Unbreakable Care Shampoo, Conditioner, and Root Lift Thickening Spray feature a PROTEINFUSION blend with regenerative keratin protein. This blend penetrates the hair's core to restore bonds and resilience, creating a protective barrier. It is combined with collagen, biotin, and spirulina, which enhance strength, flexibility, and shine for overall hair and scalp health.

Haircare that thickens, instantly

Hair thinning can have many causes, but volume loss from damage-induced breakage is significant. The Unbreakable Care Shampoo and Conditioner utilize advanced densifying technology to create millions of weightless, micro-thickening bonds between strands for visibly thicker hair after one use. For enhanced results, use the Unbreakable Care Anti-Breakage Root Lift Spray, which weightlessly thickens every strand by +3.4%. This creates the feeling of having an extra 3,000 strands of fuller, thicker hair.

Ingredients that boost hair volume

A combination of repairing ingredients provides the best protein treatment for fine hair. Nexxus’ PROTEINFUSION blends are unique in every range, customized for specific hair needs. In the Unbreakable Care Range, NEXXUS combines advanced regenerative keratin protein with collagen, biotin, and spirulina. These protein-rich ingredients are known for their ability to boost fine strands. Using this sulfate-fee, three-product strong system with gentle styling practices will help you achieve fuller, thicker-looking hair.

Achieve thicker, stronger hair with protein science

For those with fine, fragile hair, achieving lasting volume and strength no longer has to be a challenge. By leveraging targeted protein science, it is possible to address breakage and lack of density at their source. The NEXXUS Unbreakable Care system, featuring a specialized PROTEINFUSION blend with arginine, offers a direct solution. It works to repair damage, build resilience from within, and instantly create visible thickness. Adopting a complete, protein-focused regimen is the key to unlocking stronger, fuller, and healthier-looking hair.
