GIOVANNI Biotin & Collagen Strengthening Shampoo — 24 oz Vegan, Volumizing & Hydrating

GIOVANNI Biotin & Collagen Strengthening Shampoo is a vegan, cruelty-free volumizing shampoo formulated with biotin, collagen, and hyaluronic acid to help strengthen, thicken, and hydrate hair.

This 24 oz salon-size bottle from GIOVANNI combines biotin and collagen with moisturizing hyaluronic acid to improve hair texture and body without harsh chemicals. The formula is Leaping Bunny certified and designed for everyday use on all hair types. It aims to boost volume and manageability while supporting visibly fuller-feeling strands.

How does this shampoo make hair feel thicker and fuller?

The blend of biotin and collagen in the formula supports the appearance of thicker hair by coating and plumping each strand for more noticeable body. Hyaluronic acid helps retain moisture so hair looks smoother and less prone to frizz, which enhances the perception of density. Regular use creates a cleaner, more volumized foundation before styling.

• Biotin and collagen work together to thicken and smooth each strand.
• Hyaluronic acid restores hydration for bounce and reduced frizz.
• Lightweight lather cleanses without weighing hair down.
• 24 oz size offers extended use for consistent results.

Will this shampoo work for my hair type and color-treated hair?

GIOVANNI formulated this shampoo to be suitable for all hair types, including fine, curly, straight, and color-treated hair. Its gentle, non-harsh ingredients aim to preserve natural vibrancy while improving texture. For color-treated hair, follow with a conditioner formulated for color protection to maintain shade longevity.

• Safe for fine, medium, and coarse textures.
• Gentle enough for chemically treated and colored hair.
• Use with complementary conditioner for best color care.

What makes this product vegan and eco-conscious?

This shampoo is labeled vegan and Leaping Bunny certified, ensuring no animal-derived ingredients and cruelty-free testing. GIOVANNI emphasizes natural and organic components and avoids harsh sulfates and questionable additives, aligning with eco-chic haircare values. The packaging size supports fewer replacements, reducing waste over time.

• Vegan formula with plant-forward ingredients.
• Leaping Bunny certified cruelty-free standard.
• Free from harsh chemical detergents that can strip hair.

How should I use it to get the best results?

Apply a quarter-sized amount to wet hair, then gently massage into scalp and through lengths to create a light lather. Rinse thoroughly and repeat if needed; follow with a nourishing conditioner to seal moisture and enhance softness. For added volume, apply a lightweight leave-in or root lifter on damp hair and style as usual.

• Massage into scalp for circulation and even distribution.
• Rinse well and pair with conditioner to lock in hydration.
• Use consistently for visible texture and volume improvements.

Who is this for: This 24 oz GIOVANNI Biotin & Collagen Strengthening Shampoo is ideal for anyone seeking vegan, salon-quality cleansing that adds body and hydration—especially those with fine or limp hair wanting fuller texture, people who prefer cruelty-free products, and users who need a larger bottle for home or family use.
