GIOVANNI Biotin & Collagen Strengthening Shampoo — 24 oz, Vegan, Color-Safe Volume Boost

GIOVANNI Biotin & Collagen Shampoo is a salon-grade, vegan shampoo designed to strengthen and add noticeable volume while being gentle on color-treated hair.

This full-size 24 oz bottle combines biotin and collagen with botanical actives and hyaluronic acid to refresh strands, improve texture, and support a fuller-looking finish without harsh sulfates or animal testing. Formulated to work on all hair types, it cleanses while promoting manageability and is suitable for daily use or as part of a thicker-hair routine.

How does this shampoo build strength and improve texture?

The formula pairs biotin and collagen to help firm and smooth each strand, helping hair feel stronger and appear thicker. Hyaluronic acid adds humectant properties that help retain moisture, reducing the roughness that can make hair look thin and frizzy.

• Biotin supports hair resilience and surface smoothness.
• Collagen helps improve strand body and thickness perception.
• Hyaluronic acid locks in hydration for softer, more pliable hair.
• Sulfate-free approach maintains natural oils and color.

Will it add volume without weighing hair down?

This shampoo is formulated to lift the hair shaft and enhance natural body so styles look fuller without residue. Lightweight cleansing agents remove buildup while conditioning ingredients maintain slip for easy detangling.

• Volumizing actives boost lift at the roots and along the shaft.
• Fast-rinsing texture prevents heavy film on fine hair.
• Gentle surfactants preserve natural bounce and movement.
• Safe for color-treated hair, reducing premature fade from harsh cleansers.

Is this shampoo eco-friendly and cruelty-free?

Yes — GIOVANNI emphasizes eco-conscious, salon-quality formulations. The product is vegan, Leaping Bunny certified, and made without animal testing, reflecting a commitment to sustainable beauty standards.

• Vegan formulation with plant-derived ingredients.
• Leaping Bunny cruelty-free certification.
• Free from aggressive sulfates and unnecessary harsh chemicals.
• Large 24 oz size reduces packaging waste per use.

How should I use it for best results?

Massage a palm-sized amount into wet hair and scalp, work into a lather, then rinse thoroughly. For best results, follow with a complementary GIOVANNI conditioner or treatment to seal moisture and enhance shine.

• Apply to wet hair and focus on the scalp for cleansing.
• Rinse and repeat if hair is particularly oily or product-heavy.
• Follow with a conditioner aimed at strengthening or volumizing.
• Use regularly to maintain healthier-looking texture and volume.

Who is this for: GIOVANNI Biotin & Collagen Shampoo is ideal for anyone seeking a vegan, salon-quality cleaner that strengthens strands and boosts volume—especially those with fine, limp, or color-treated hair looking for improved texture without harsh detergents. It’s also a good pick for shoppers prioritizing cruelty-free, plant-forward formulations in a generously sized bottle for frequent use.
