Nexxus Diamtress Volume Shampoo for Fine, Flat Hair — 13.5 oz, Silicone-Free, Elastin Protein

Nexxus Diamtress Volume Shampoo is a salon-grade, silicone-free cleanser designed to gently lift fine, flat hair and boost strand diameter for visible movement and body.

If your hair tends to lie flat at the roots or looks limp through the day, this Nexxus formula targets weightless volume without heavy silicones. Blended with Green Tea Extract and concentrated elastin protein, the shampoo cleanses while supporting the structural fullness of each fiber so styles hold better and hair feels bouncier. It is crafted to work into a routine with conditioners and styling products that maintain lift and manageability.

How does Nexxus Diamtress add volume without weighing hair down?

The shampoo uses a lightweight, rich formula that avoids heavy silicones and focuses on ingredients that subtly thicken and lift each hair strand. By cleansing impurities and adding structural protein, it lets hair move more freely from the root. The result is detectable body without residue or stiffness.

• Silicone-free base prevents buildup that flattens fine hair
• Concentrated elastin protein supports strand structure
• Green Tea Extract contributes to a fuller-looking diameter per fiber
• Rinses clean for easier styling and longer-lasting lift

When should I use this shampoo in my routine?

Use Diamtress as your primary cleansing step whenever you want lightweight volume—daily or several times a week depending on oiliness and styling needs. Follow with a compatible lightweight conditioner or a volumizing treatment to keep the mid-lengths and ends nourished without losing lift at the roots.

• Apply to wet hair, lather, then rinse thoroughly
• Ideal before volumizing conditioners or root-lifters
• Works well ahead of blow-drying or air-drying for added body

What ingredients are responsible for the thicker look and feel?

Key actives include Green Tea Extract and concentrated elastin protein, chosen to enhance the apparent diameter and resilience of individual hairs. These components combine with a salon-grade cleansing system to remove excess oil and product residue so the hair reads as fuller and more movable.

• Green Tea Extract for strand-supporting properties
• Concentrated elastin protein to help reinforce hair structure
• Formulated without silicones to avoid weighing fine hair down

Will this shampoo work with colored or chemically treated hair?

Diamtress is formulated as a gentle volumizing cleanser compatible with many color and chemical routines, but pairing it with color-care products is recommended if you prioritize color longevity. For highly porous or recently treated hair, use a complementary conditioner to restore softness while preserving lift.

• Gentle cleansing suitable for many color-treated hair types
• Follow with a nourishing conditioner for treated ends
• Test with color-safe products if color retention is a top concern

Who is this for: Nexxus Diamtress Volume Shampoo is designed for people with fine, limp, or flat hair who want salon-style volume without heavy build-up. It suits anyone seeking a silicone-free volumizing cleanser that pairs easily with styling tools and treatments to maintain lift, movement, and a natural-feeling finish.
