Born in salons and perfected by science, each Nexxus system is crafted with proteins extracted from nature's most precious ingredients. Nexxus uses advanced scientific methods to identify the protein needs of hair, and we create highly effective custom formulas. Nexxus Diametress Conditioner targets weakened hair fibers and uses its advanced conditioning technology to help boost volume and body. By creating a protective barrier, this hair thickening conditioner, which is enriched with Concentrated Elastin Protein and Green Tea Extract, nourishes and moisturizes hair while also working to strengthen and volumize. When used with the rest of the Nexxus Diametress Regimen, it can even increase the diameter of hair strands by 17% for noticeable volume and thicker-looking hair that retains natural movement. Nexxus recommends: Use this Nexxus volumizing conditioner as Step 2 in the Luscious Volume Collection to reawaken fine and flat hair with beautiful resiliency. Step 1: Wash your hair with Nexxus Diametress Volume Shampoo. Work it into a lather and rinse. Step 2: Smooth and press the creamy Nexxus Diametress Volume Conditioner onto wet hair and wait 3 minutes before rinsing out thoroughly. Step 3: Finish with Nexxus Diametress Leave In Conditioning Cr�me or Nexxus Lavish Body Gel Spray. Apply either product evenly throughout damp hair, comb, and style as required.
