Swim Strong Shampoo Bar
A strengthening shampoo bar formulated specifically for hair exposed to salt, chlorine and sun. Rice protein rebuilds the hair shaft; seaweed restores shine and elasticity. Works as both shampoo and body wash. One bar equals roughly 50 washes.
Leave-In Hair Conditioner — 6 fl oz
Apply to damp hair — no rinsing needed. Detangles instantly, adds shine, and prevents the brittleness that regular swimming causes. Non-greasy. All hair types.
Nourishing Body Lotion — 8.5 fl oz
Fast-absorbing and silky — replenishes moisture stripped by salt and chlorine. Proprietary antioxidant blend with shark-free squalane. No greasy residue. The final step in the post-swim routine.

Swim Strong Shampoo Bar + Leave-In Conditioner + Nourishing Body Lotion — the complete post-swim routine for people who care what goes back into the water. Reef-Safer™. USDA BioBased.
Most shampoos strip
what swimming already takes.
Salt, chlorine and UV exposure strip protein and moisture from hair every time you swim. Most shampoos compound the damage with harsh detergents. Stream2Sea Swim Strong is built to cleanse and replenish at the same time.
Rice protein rebuilds hair strength from the inside
Each wash deposits rice protein into the hair shaft, helping to restore the strength that chlorine and salt deplete. With regular use, hair feels stronger and less prone to breakage — not just clean.
Seaweed restores shine and elasticity
Wakame and other seaweed extracts are rich in minerals and vitamins that restore elasticity and shine to hair damaged by daily water exposure. The lightweight lather rinses cleanly without leaving residue.
Ocean Bound Plastic Certified bottles
Every conditioner and lotion bottle is Ocean Bound Plastic Certified — made from plastic recovered before it could reach the ocean.
Four botanicals.
One antioxidant core.
Every Stream2Sea hair and body formula is built around the same four-ingredient antioxidant blend — chosen to protect, nourish and restore hair and skin when sun, salt and chlorine take their toll.
Biodegradability — tested where it actually matters
Most biodegradability testing happens in sewage treatment plants under controlled lab conditions. Stream2Sea tests in both freshwater and saltwater environments — because that is where these products actually end up when swimmers shower at dive sites, on boat decks and at outdoor rinse stations. The formula breaks down completely within 30 days in real-world water conditions.
Wash. Condition. Nourish.
A complete post-swim or post-dive routine in three products — takes under five minutes.
Rinse first
Rinse hair and skin with fresh water to remove the bulk of salt or chlorine before washing.
Before washingBar shampoo and body wash
Lather one of the Swim Strong bars and massage through hair and over the body. The rice protein deposits into the hair shaft with every wash. Rinse well.
Swim Strong BarLeave-in conditioner
On damp hair, apply Leave-In Conditioner and finger comb through evenly. No rinse needed, especially if you're about to dive.
Leave-In ConditionerBody lotion
Apply Nourishing Body Lotion to damp skin while pores are still open. Fast-absorbing — no greasy finish, no residue.
Body Lotion“I was watching people wash their hair on the deck of a liveaboard — fragrant suds streaming directly into the water over a pristine coral reef. That image is why Stream2Sea exists. Not just the sunscreen slick coming off the snorkelers below. The shampoo. The body wash. The lotion. Everything we put on our bodies eventually reaches the water. Every formula I make has to be able to answer for that.”
What swimmers and divers are saying
“It lathers up quickly with a lot of lather and my hair does not smell like chlorine, which is the best! I swim in an indoor pool every other day.”
“This by far is the best leave in conditioner that is reef safe, smells fantastic, and leaves your hair silky smooth after a day in the ocean. A must have item after scuba diving.”
“It's thinner consistency so a little goes a long way. It's quickly absorbed and smells like mild sweet coconut. So mild that I don't have to worry about my pets and their sensitive noses.”
“I am so grateful I found this product, it saves my salt and wind damaged hair from being on the boat. Keeps split ends at bay and prevents tangles, keeping my hair maintenance easy.”

What swimmers ask us most
How does the Swim Strong bar differ from the other shampoo bars?
The three bars share the same rice water protein and antioxidant base but are each formulated for a different hair concern. Swim Strong includes peppermint to gently cleanse swimmers' hair and help it feel strong and resilient after the water. The Naturally Naked bar is completely fragrance-free — no essential oils, no botanical fragrance — and is formulated for sensitive skin or anyone who prefers an unscented wash. The Color Protect bar is formulated to preserve color-treated hair.
Is the Swim Strong Bar formulated for all hair types?
Yes. The Swim Strong bar is a mild, balanced formula that works for straight, wavy and curly hair. For fine hair, use a small amount and focus on the scalp. For thicker or coarser hair, allow the lather to work through to the ends. Pair with the Leave-In Conditioner for best results, especially if your hair is regularly exposed to salt or chlorine.
Is the Swim Strong bar suitable for color-treated hair?
Yes, though if color preservation is your primary concern the Color Protect bar is specifically formulated for that. Swim Strong is color-safe and will not accelerate color fade, but its formulation is optimised for strength and resilience rather than color longevity.
Is the conditioner and lotion the same formula as the 32 fl oz sizes?
Yes — exactly the same formula, same concentration, same USDA BioBased and biodegradable standard. The 6 fl oz conditioner and 8.5 fl oz lotion are the standard full-size retail bottles. All bottles are Ocean Bound Plastic Certified.
What does Reef-Safer mean on the shampoo bar?
“Reef-safe” is an unregulated marketing term — any brand can use it with no testing required. Stream2Sea uses Reef-Safer™ because every ingredient is evaluated against published aquatic toxicity data.
Your daily routine.
Without the daily guilt.
