Bumble and bumble Seaweed Hydrating Conditioner — 6.7 fl oz Lightweight Daily Moisture for Fine to Medium Hair, Reduces Frizz

Bumble and bumble Seaweed Hydrating Conditioner is a lightweight, plant-forward daily conditioner that hydrates strands, smooths frizz, and helps balance scalp moisture for fine-to-medium hair.

This conditioner pairs nutrient-rich sea botanicals with a mostly natural, vegan formula to give hair manageable softness without weighing it down. Designed to be used alone or after the Seaweed Shampoo, it targets scalp and strand hydration while remaining color-safe and suitable for regular washing routines.

How does this conditioner hydrate hair without making it heavy?

The formula relies on lightweight sea-derived extracts—Royal Sugar Kelp, Pacific Sea Kelp, and Green Microalgae—that attract and hold moisture without coating the hair in heavy oils. Conditioning agents are balanced so fine-to-medium hair gains slip and smoothness while retaining natural movement.

• Light-texture emulsion that detangles without weight.
• Seaweed extracts that support moisture retention.
• Formulated for daily use and quick rinse-out.

Will it reduce frizz and improve scalp hydration?

Yes — when used as a regimen with the Seaweed Shampoo, clinical testing reported improved scalp hydration for most participants after three uses. The conditioner helps smooth the hair cuticle to reduce surface frizz while contributing to overall scalp comfort.

• Clinical test: 91% showed scalp hydration improvement when paired with Seaweed Shampoo.
• Cuticle-smoothing ingredients to minimize frizz and flyaways.
• Color-safe formulation suitable for treated hair.

How should I use it for best results on fine, wavy, or curly hair?

After shampooing, apply a small amount from mid-lengths to ends; leave in briefly, then rinse. For extra hydration, comb through with a wide-tooth comb and leave for a couple of minutes before rinsing. Use daily or as needed depending on your washing routine and hair density.

• Use sparingly on roots to avoid buildup for fine hair.
• Work more product into dry ends for medium-dry or curly textures.
• Pair with Seaweed Shampoo for clinical-backed scalp hydration benefits.

What is in the formula and is it natural or vegan?

The conditioner is made from 97% naturally derived ingredients (ISO 16128) and is vegan, featuring a trio of sea botanicals along with gentle conditioners and color-safe agents. It avoids heavy petroleum-derived silicones, favoring plant and mineral-based materials that are kinder to scalp and strands.

• Key botanicals: Royal Sugar Kelp, Pacific Sea Kelp, Green Microalgae.
• Vegan and largely plant-derived (97% natural origin per ISO 16128).
• Formulated to be color-safe for treated hair.

Who is this for: This conditioner is aimed at people with fine to medium hair textures who want daily hydration and smoother, less frizzy hair without heaviness. It also fits those who wash hair frequently, prefer vegan and largely naturally derived products, or want a color-safe, sea-botanical approach to scalp and strand moisture. If you have very coarse or extremely dry hair, you may prefer a richer treatment; otherwise, this is an easy daily option to maintain lightweight softness and scalp balance.
