Bumble and bumble Seaweed Hydrating Shampoo — 8.5 oz Sulfate-Free, Lightweight Hydration for Fine to Medium Hair

Bumble and bumble Seaweed Hydrating Shampoo is a gentle, sulfate-free cleanser that rinses away oil and product buildup while helping rebalance scalp moisture and leave hair feeling clean and hydrated.

This lightweight shampoo is formulated with a trio of sea-derived botanicals—Royal Sugar Kelp, Pacific Sea Kelp, and Green Microalgae—designed to refresh hair and support scalp hydration without heavy residue. The formula is 93% naturally derived and color-safe, making it a good daily option for fine-to-medium hair textures and anyone wanting a milder wash that won’t strip natural oils. Clinical testing alongside the Seaweed Conditioner showed a high rate of improved scalp hydration after three uses, indicating its suitability for routines focused on scalp health and manageable strands.

How does this shampoo clean without drying out my hair?

The Seaweed Hydrating Shampoo uses gentle surfactants instead of harsh sulfates, so it effectively removes dirt, oil, and styling residues while preserving natural moisture. Seaweed-derived ingredients add lightweight conditioning compounds that soften without coating or weighing down fine strands.

• Sulfate-free cleansing agents that lift buildup gently
• Royal Sugar Kelp and Pacific Sea Kelp deliver minerals and humectant-like benefits
• Formulated to rinse clean without heavy silicones
• Color-safe formulation for dyed hair maintenance

Will this work for my hair type—curly, wavy, straight or fine?

Yes: the shampoo is intentionally lightweight, so it suits fine-to-medium hair and performs well on straight, wavy, and many curly textures. It refreshes scalp hydration while keeping strands bouncy and manageable rather than limp or greasy.

• Fine-to-medium hair benefits from balanced moisture without weight
• Wavy and curly hair gains gentle cleansing that preserves natural pattern
• Daily washers can use it without over-drying
• Color-treated hair stays protected with a color-safe formula

What are the key active ingredients and how do they help?
