Bumble and bumble Seaweed Hydrating Shampoo is a lightweight, sulfate-free cleanser that removes dirt and buildup while helping balance scalp moisture for fine to medium hair.

This gentle shampoo combines marine botanicals and green microalgae to cleanse without stripping natural oils. Formulated from 93% naturally derived ingredients and designed to work well with daily washing routines, it helps refresh strands and scalp while supporting color-treated hair. Clinical testing alongside the Seaweed Conditioner showed improved scalp hydration for most participants after a few uses. The texture is light and easy to lather, making it suitable for fine-to-medium textures and for anyone who wants a hydrating yet non-heavy wash.

How does this shampoo hydrate without weighing hair down?

The formula uses a trio of sea botanicals—Royal Sugar Kelp, Pacific Sea Kelp, and Green Microalgae—to deliver moisture and nutrients while lightweight surfactants gently lift away oil and product residue. Instead of heavy oils or silicones, these marine-derived ingredients help retain hydration at the scalp and strands.

• Royal Sugar Kelp helps bind moisture to hair and scalp.
• Pacific Sea Kelp provides lightweight nutrient support.
• Green Microalgae contributes antioxidants and conditioning benefits.
• Sulfate-free surfactants cleanse without aggressive stripping.

Will it work for color-treated or chemically processed hair?

Yes—this shampoo is color-safe and formulated to be gentle on treated hair. Its mild cleansing system removes styling product and excess oil while preserving color vibrancy when used as part of a color-care routine.

• Color-safe formula protects hair tone and shine.
• Removes buildup that can dull color over time.
• Lightweight conditioning avoids film that might affect color payoff.

How should I use Seaweed Hydrating Shampoo for best results?

• Rinse completely to avoid residue buildup.
• Use with the Seaweed Conditioner 2–3 times weekly or as desired for daily washers.
