The Seaweed Bath Co. Volumize Shampoo — Lavender Scent, 12 oz, Seaweed + Barley Protein for Fuller, Lightweight Body

Seaweed Bath Co. Volumize Shampoo is a lavender-scented, plant-forward thickening shampoo formulated with sustainably harvested Atlantic seaweed, green algae, barley protein and argan oil to help hair look fuller while maintaining softness and shine.

Built around ocean-derived botanicals, this 12‑ounce bottle combines nutrient-rich seaweed and green algae with barley protein to create lift and body for normal to fine hair. The formula is scented with lavender for a relaxed shower experience and includes argan oil, aloe and vitamin E to support manageability and moisture. It’s vegan, cruelty‑free, and free from sulfates, parabens and gluten; the bottle is partially made from post‑consumer recycled plastic.

How does this shampoo add volume without weighing hair down?

The shampoo uses barley protein and green algae to coat and thicken individual strands, creating the appearance of fuller hair without heavy silicones. Lightweight emollients like argan oil and aloe help keep hair soft rather than stiff, so lift at the roots lasts while hair remains touchable.

• Barley protein: fortifies strands and increases diameter.
• Green algae: provides nutrients that support body and texture.
• Argan oil and aloe: moisturize without heavy residue.
• Sulfate-free base: cleanses gently to preserve natural volume.

Is this safe for color-treated or sensitive scalps?

The gentle, sulfate-free formula is suitable for color‑treated hair and designed to minimize stripping of dye. With calming lavender and aloe, it’s formulated to be mild, though anyone with a specific scalp condition should patch-test or consult a professional.

• Color-safe: cleanses without aggressive sulfates.
• Soothing ingredients: aloe and vitamin E help comfort the scalp.
• Cruelty-free and vegan: Leaping Bunny certified.
• Free of parabens and gluten for fewer common irritants.

What does sustainably harvested seaweed bring to the formula?

Sustainably harvested Atlantic seaweed contributes trace minerals and polysaccharides that support hair texture and scalp health. The brand sources seaweed with attention to environmental practices and partners with marine conservation efforts, reflecting a commitment to ocean stewardship.

• Atlantic seaweed: nutrient-dense botanical for thicker-feeling hair.
• Environmentally mindful sourcing: supports marine conservation initiatives.
• Complementary botanicals: green algae and barley protein enhance effects.
• Packaging focus: bottle contains 50% post-consumer recycled plastic.

How should I use this shampoo for best results?

Work a small amount into wet hair, concentrating at the roots to encourage lift and then through the lengths to cleanse and condition. Rinse thoroughly and follow with a conditioner suited for fine or color-treated hair; use daily or as needed for maintenance.

• Apply to wet hair and massage into scalp and roots.
• Rinse well and pair with a lightweight conditioner.
• Use regularly to maintain volume and shine.
• Suitable for men, women and children with normal to fine hair.

Who is this for: Seaweed Bath Co. Volumize Shampoo is aimed at anyone with fine, limp or normal hair who wants noticeable lift without heavy build-up, and who prefers plant-forward, cruelty-free personal care. It’s a good fit for color-treated hair, shoppers seeking environmentally conscious ingredients and people who enjoy a calming lavender scent during their routine. If you need a clinical scalp treatment or have severe sensitivity, consult a specialist before use.
