Hair That Looks Great.
Oceans That Stay Clean.
You care about what goes into your body — and what goes into the water. Stream2Sea shampoo bars deliver a rich lather that actually cleans without stripping — with dramatically less packaging waste and zero compromise on your values.
Replace your shampoo bottles.
The average person goes through 11 shampoo bottles a year. Most end up in landfill or waterways. And conventional shampoo formulas contain chemicals that are actively harmful to coral reefs and marine life. Stream2Sea shampoo bars solve the packaging challenge and are rigorously tested and ridiculously effective.
One bar = 2–3 liquid bottles
Each Stream2Sea bar lasts up to 80 washes — saving money, space in your bag, and plastic from the planet.
No compromise on performance
Rich, creamy lather. Genuinely clean hair. Not a downgrade — an upgrade with a conscience.
Formulated by ocean scientists
Founded by marine biologist Autumn Blum. Every ingredient is evaluated against aquatic toxicity data — not just what looks good on a label.
How to make the switch
Going from liquid to bar takes one wash. Here's all you need to know.
Wet your hair
Thoroughly soak hair with warm water to open the cuticle and prep for lather.
Rub the bar
Glide the bar from root to tip 3–5 times, or lather in hands and apply directly.
Massage & lather
Work into a rich lather. Your scalp will love the clean ingredients.
Rinse thoroughly
Rinse well, let the bar dry on its tray, and enjoy hair that's truly clean.
Find the one made for you
Whether you swim every day, have a sensitive scalp, or want to protect your color — there's a bar built for your life.
Swim Strong
After every dive, your hair is fighting chlorine, salt, and sun damage. Swim Strong removes all of it while restoring strength and softness. Your post-swim ritual, sorted.
Naturally Naked
Fragrance-free and stripped back to essentials. No dyes, no perfume, no extras — just what your hair actually needs. Calm, balanced, and beautifully clean.
Color Protect
Color fades because most shampoos are too harsh. Color Protect is enriched with botanicals that lock in vibrancy, add shine, and keep your color looking fresh longer.
Choose your formula
All bars are $14.95 — that's less than most liquid shampoos, and they last 2–3x longer.
Swim Strong Shampoo Bar
Removes chlorine, salt & sun damage. Restores softness and strength after every swim, surf, or dive.
Naturally Naked Shampoo & Body Bar
Pure, fragrance-free, and minimal. Leaves hair fresh, soft and balanced — nothing extra, just what your hair truly needs.
Color Protect Shampoo Bar
Locks in vibrancy and shine while protecting color from fading. Your hair stays as bold and bright as you are.
They made the switch
"I was skeptical at first — I've tried bar shampoos before and they left my hair feeling like straw. This is completely different. My hair is soft, clean, and honestly looks better than when I was using my $30 salon shampoo."
"As a diver I'm in salt water almost every day. Nothing was getting rid of that salt-damaged, crunchy feeling — until I found Swim Strong. Game changer. I've already converted three people in my dive club."
"My scalp is super sensitive and I've been hunting for a shampoo without fragrance or harsh chemicals for years. Naturally Naked is it. Finally something that works without causing irritation. I won't go back."
You'll love it. Or we'll make it right.
We stand behind every bar we make. If you're not completely satisfied, reach out and we'll sort it out — no awkward returns, no small print.
Still on the fence?
Why do you say "Reef-Safer" instead of "reef-safe"?
Because "reef-safe" is an unregulated marketing term with no scientific standard behind it. Any brand can print it on a bottle. Stream2Sea was founded by marine biologist Autumn Blum, who actually knows what goes into the water — and what it does when it gets there. Reef-Safer is our term for formulas that have been evaluated against real aquatic toxicity data. It means something. "Reef-safe" doesn't.
Will a shampoo bar actually clean my hair as well as liquid?
Yes — and often better. The common concern is that bars leave residue or feel different. Stream2Sea bars are formulated to produce a rich lather and rinse completely clean. The adjustment period (if any) is usually 1–2 washes while your scalp recalibrates from sulfate-heavy liquid shampoos.
How long does one bar actually last?
Up to 80 washes, which is roughly equivalent to 2–3 bottles of liquid shampoo. The key is letting the bar dry fully between uses — that's what the tray is for. A wet bar stored in a puddle will dissolve faster.
What makes Stream2Sea different from other "reef-safe" brands?
Stream2Sea was founded by a marine biologist. Every ingredient is evaluated for its impact on coral, fish, and marine ecosystems — not just labeled reef-safer for marketing purposes. The formula is free from oxybenzone, octinoxate, microplastics, and other known marine toxins — and every ingredient is evaluated against aquatic toxicity data before it goes in.
I have color-treated hair. Will a bar strip my color?
The Color Protect bar is specifically formulated to be gentle on color-treated hair. It's sulfate-free (sulfates are the primary cause of color fading) and enriched with botanicals that help lock in vibrancy. Many customers report their color lasting noticeably longer after switching.
Is the Naturally Naked bar really fragrance-free?
Yes — no added fragrance of any kind, including "natural" fragrance which can still cause reactions in sensitive individuals. The bar has a very faint natural scent from the ingredients themselves, but nothing added.
Can I use these for travel?
Absolutely. No liquids, no leaks, no TSA baggage worries. One bar fits in any carry-on and won't explode in your toiletry bag. The Travel Tin is designed specifically to keep your bar dry and protected on trips.
Ready to wash with a clear conscience?
Join thousands of swimmers, divers, travelers and conscious consumers who've made the switch. Your hair will thank you. So will the reef.
No waxy buildup. Less waste. Just clean hair.
