Bumble and bumble Seaweed Hydrating Shampoo — 33.8 fl oz Liter, Lightweight Color-Safe Scalp Hydration for Fine to Medium Hair

Bumble and bumble Seaweed Hydrating Shampoo is a lightweight, color-safe cleanser formulated with seaweed extracts to remove buildup while helping balance scalp moisture.

This shampoo blends nutrient-dense marine botanicals with a gentle surfactant system to lift dirt, oil, and styling residue without leaving hair feeling stripped. It’s crafted for everyday use and designed to feel weightless on fine-to-medium strands while delivering scalp-hydrating benefits. The formula is safe for color-treated hair and offers a fresh, uplifting scent that layers well with styling products.

How does this shampoo hydrate the scalp without weighing hair down?

The formula uses a trio of marine-derived botanicals—Royal Sugar Kelp, Pacific Sea Kelp, and Green Microalgae—that help condition the scalp and hair surface without heavy oils. Lightweight cleansing agents clear impurities so the seaweed extracts can help retain surface moisture. Results from controlled testing showed improved scalp hydration for most participants when used with the matching conditioner.

• Royal Sugar Kelp: supports moisture-retention at the scalp.
• Pacific Sea Kelp: nourishes hair cuticles for smoother feel.
• Green Microalgae: lightweight conditioning at the surface.
• Gentle surfactants remove buildup without harsh stripping.

Will this shampoo work for color-treated or daily-washed hair?

Yes—this Seaweed Shampoo is labeled color-safe and formulated to be gentle enough for frequent washing. Its lightweight profile makes it a good option for people who shampoo daily or who want to preserve color vibrancy while clearing residue. Pairing with the Seaweed Conditioner enhances hydration and manageability.

• Color-safe formula protects treated hair tones.
• Lightweight feel prevents limpness on fine hair.
• Designed for daily or regular cleansing routines.

How should I use the liter bottle and what about dispensing?

This product comes in a 33.8 fl oz liter-size bottle; the dispenser pump is sold separately. For best results, apply to wet hair, lather gently at the scalp, then rinse thoroughly. Use with the matching Seaweed Conditioner to maximize scalp hydration and improve detangling.

• Apply to thoroughly wet hair and massage into the scalp.
• Rinse completely and follow with Seaweed Conditioner.
• Purchase a compatible liter pump for easier dispensing.

What does it smell like and how does scent perform with styling?

The fragrance is crisp and refreshing, with top notes of apple and leafy greens and subtle accents of mint, pineapple, and white woods. It’s formulated to be light so it doesn’t compete with leave-in products or heavy styling fragrances. The scent lingers subtly on hair without becoming overpowering.

• Top notes: crisp apple and leafy greens.
• Accents: mint leaf and pineapple for brightness.
• Base: white woods for a clean, balanced finish.

Who is this for: Bumble and bumble Seaweed Hydrating Shampoo suits people seeking a gentle, everyday cleanser that removes oil and product buildup while supporting scalp moisture—especially those with fine-to-medium hair or anyone washing frequently. It’s also appropriate for color-treated hair and users who prefer lightweight, botanical-based formulations with a fresh scent.
