Nexxus Diametress Volume Conditioner for Fine, Flat Hair 13.5 oz — Elastin Protein & Lightweight Body

Nexxus Diametress Volume Conditioner is a salon-formulated, protein-enriched conditioner that strengthens and adds body to fine, flat hair for visibly thicker-looking strands.

Created from salon research and advanced ingredient science, this Nexxus conditioner targets fragile hair fibers to deliver lightweight nourishment and fuller-looking results. Formulated with concentrated elastin protein and green tea extract, it helps protect and condition without weighing hair down. Use as the second step in the Diametress regimen after the matching volumizing shampoo, and follow with a leave-in product for best styling performance.

How does this conditioner add volume without leaving hair heavy?

The formula focuses on rebuilding and coating each strand with a lightweight protective layer that boosts diameter rather than saturating hair with heavy oils. This approach maintains hair’s natural movement while creating perceptible body. The result is fuller-looking hair that still feels soft and bouncy.

• Concentrated elastin protein helps reinforce weak fiber structure for thicker-feeling strands.
• Green tea extract adds antioxidant-rich moisture without weight.
• Advanced conditioning technology seals cuticles to lock in lightweight nourishment.

When and how should I use Nexxus Diametress Volume Conditioner in my routine?

Use this product as Step 2 after cleansing with Nexxus Diametress Volume Shampoo. Apply to wet hair, smooth through from mid-lengths to ends, allow a short processing time, then rinse to reveal conditioned hair ready for styling. Pair with the brand’s leave-in crème or body gel spray for added manageability and volume hold.

• Step 1: Shampoo with Nexxus Diametress Volume Shampoo and rinse thoroughly.
• Step 2: Apply conditioner evenly and leave on for about three minutes before rinsing.
• Step 3: Finish with Nexxus leave-in products for styling and lasting lift.

What visible differences can I expect with regular use?

When used consistently within the Diametress system, this conditioner helps increase each hair strand’s diameter for a more substantial appearance. Users often notice easier styling, improved manageability, and hair that appears fuller while retaining natural movement and shine.

• Targets weakened fibers to reduce limpness and boost body.
• Helps increase strand diameter for thicker-looking hair.
• Leaves hair smoother and easier to comb or style without stiffness.

Is this product suitable for my hair type and concerns?

This conditioner is formulated specifically for fine, flat, or limp hair that needs lightweight strengthening and volume. It’s ideal if you want to add body without sacrificing softness or movement. Avoid if you require heavy hydration for severely dry, coarse hair, as the focus here is volume and light conditioning.

• Best for fine, thin, or flat hair seeking more body and resilience.
• Works well with color-treated and normal hair that becomes limp.
• Not intended as an intensive moisturizing treatment for very dry, coarse hair.
