Nexxus Diamtress Volume Shampoo for Fine, Flat Hair — 13.5 oz, silicone-free lift & elastin protein

Nexxus Diamtress Volume Shampoo is a salon-grade, silicone-free formula designed to boost volume by increasing the diameter of fine, flat hair strands.

This shampoo from Nexxus combines green tea extract with concentrated elastin protein to create a richer, reparative lather that adds lift and movement without weighing hair down. Formulated specifically for fine or limp hair, Diamtress Volume gently cleanses while targeting the cuticle and strand profile to help hair appear fuller and more resilient. It’s suitable for everyday use and pairs well with a volumizing conditioner or styling products for extra hold and shape.

How does this shampoo create more visible volume?

The formula focuses on increasing each hair strand’s diameter and restoring elasticity, which collectively produce fuller-looking hair. Instead of coating hair with heavy silicones, it uses concentrated elastin protein to support strand structure and green tea extract for lightweight nourishment.

• Elastin protein enhances strand resilience and thickness.
• Green tea extract provides antioxidant support without buildup.
• Silicone-free base prevents weighty residue that flattens fine hair.
• Creates a fuller look by improving strand body and movement.

Will it work on color-treated or chemically processed hair?

Nexxus Diamtress Volume Shampoo is formulated to be gentle enough for hair that’s been colored or lightly processed, though results can vary based on treatment history. It cleanses while helping reinforce weakened strands, making it a practical choice when you want lift without harsh cleansing agents.

• Safe for most color-treated hair when used as directed.
• Supports strand strength after light chemical services.
• Avoids heavy silicones that can dull color or weigh hair down.

How should I use it for best results on limp hair?

Apply Nexxus Diamtress Volume Shampoo to wet hair, massage into the scalp and lengths, then rinse thoroughly—repeat if hair is especially oily or product-laden. Follow with a lightweight volumizing conditioner, concentrating on mid-lengths and ends, and style with root-lifting techniques for maximum impact.

• Use daily or several times a week depending on oiliness and styling frequency.
• Pair with a volumizing conditioner for balanced moisture and lift.
• Blow-dry with a round brush or use root-boosting products for extra lift.

What kind of scent and texture can I expect?

The shampoo has a rich, salon-style texture that foams well to carry away impurities while feeling luxurious during use. Fragrance is typically light and clean, designed to leave hair smelling fresh without overpowering scented styling products.

• Rich lather that rinses clean without heavy residue.
• Light, fresh scent that complements styling products.
• Silicone-free consistency that maintains hair movement.

Who is this for: Nexxus Diamtress Volume Shampoo is made for people with fine, flat, or limp hair who want lift and improved strand body without heavy fillers. It's ideal for anyone seeking salon-quality volumizing results at home, including those with color-treated hair looking to add movement and thickness without sacrificing gentle care.
