Unbreakable Care™ Thickening Conditioner

Strengthen, protect, and create fullness in your hair with Nexxus Unbreakable Care™ Thickening Conditioner, designed to weightlessly nourish and visibly thicken each strand for overall fullness, body, shine, and strength. Our breakthrough formula creates millions of light, micro-thickening bonds between strands that add shape and structure to hair while conditioning, building lasting volume, and creating visible fullness.

Product Details

  • Designed exclusively for fine hair, this thickening conditioner prevents breakage and creates weightless volume. Strands are strengthened and protected from within to give you fuller, thicker-looking hair. Light enough for daily use.
  • Benefits can be reactivated between washes for hair that’s easy to style and hard to break.
  • Designed to treat and strengthen hair fiber’s inner core from root to tip, helping prevent breakage, reduce fall out, and leave hair visibly fuller.
  • Our ProteinFusion™ Blend is carefully formulated with Advanced Keratin Protein, Biotin, and Collagen Amino Acids – ingredients all high in Arginine, which provides 2x more inner-core strengthening properties.
  • Totally free of dyes and parabens. Safe for color-treated hair.
  • Our three-step system includes the Anti-Breakage Shampoo, Thickening Conditioner, and our Root Lift Thickening Spray that works together to build fullness and reduce up to 97% of hair loss from breakage vs. non-conditioning shampoo.

Start with Unbreakable Care™ Shampoo. Then spread the Unbreakable Care™ conditioner through wet hair and rise. To complete the look, style with Unbreakable Care™ Root Lift Thickening Spray.

Did you know that fine or thin hair breaks 10x faster than any other hair type? Our Nexxus scientists analyzed various underlying causes of breakage and discovered that fine hair has a smaller inner core and 40% less protein than thick hair. This insight drove the design of our Unbreakable Care collection, aimed at addressing the causes of hair loss due to breakage for all fine and thin hair textures. This formula features an exclusive micro-thickening technology that creates weightless, thickening bonds between strands, adding shape for maximum fullness. The result is stronger, fuller, thicker-looking hair and less hair on your comb, brush, or pillow!
