SKU: HYDRO-SHAMPOO-BAR
Hydrate Shampoo Bar
Your hair drinks it up and still feels thirsty.
It goes rough between washes. It tangles at the ends. You have found the water it needs and it does not seem to hold on to any of it.
This bar was made to wash and soften in the same step. Creamy, low-foam, poured by hand in San Diego, and concentrated so it ships without a plastic bottle.

Left out on purpose
Synthetic fragrance, sulfates, soap, silicones, parabens, and dyes. Each one left out on purpose.
- The cleansing systemSodium cocoyl isethionate, sodium lauryl sulfoacetate, and caprylyl/capryl glucoside. Coconut-derived, sulfate-free and soap-free, at a pH of 4.8 to 5.2. Sodium lauryl sulfoacetate reads like a sulfate and is not one. It is a sulfoacetate, a larger molecule that stays on the surface of the hair rather than penetrating it, which is the difference that matters.
- The buttersCocoa butter, kokum butter, and sugarcane-derived squalane. They cushion the lengths while the bar cleanses.
- The slipA small amount of behentrimonium methosulfate, which is the conditioning ingredient. It is why the comb moves through afterward.
- Holding moisturePanthenol and betaine hold moisture at the strand, so hair feels hydrated once it dries rather than only while it is wet.
- For the scalpA little centella asiatica, in for how it leaves a reactive scalp feeling.
- Reach for it when youWash hair that is dry, dehydrated, or rough between washes. Have a scalp that reacts easily. Would rather keep a plastic bottle out of the routine.
- ScentLavender and geranium essential oils. Soft, herbal and a little green. It lifts in the steam and leaves with the rinse, so it does not stay in your hair through the day. Never synthetic fragrance. The unscented bar is fragrance-free and essential-oil-free, with no fragrance material of any kind in it.
- A harder bar than the one beforeThat was the reason for the reformulation. A bar that softens in the shower is the thing people give up on.
- Where it sits in your routineWash with this, then follow with the Hydrate Conditioner Bar through the lengths.
Why it washes the way it does
This is a soap-free bar. It cleanses with sodium cocoyl isethionate, a coconut-derived surfactant, at a pH of 4.8 to 5.2.
It lifts oil and buildup and leaves the scalp’s own oils where they are. That is the same starting point as the rest of the Nervous System Skincare™ line, which is to give the skin you are washing less to react to.
Full ingredient list · scented
Sodium Cocoyl Isethionate, Stearyl Alcohol, Aqua (Water), Sodium Lauryl Sulfoacetate, Cetearyl Alcohol, Caprylyl/Capryl Glucoside, Squalane, Behentrimonium Methosulfate, Panthenol, Betaine, Theobroma Cacao (Cocoa) Seed Butter, Garcinia Indica (Kokum) Seed Butter, Hydrogenated Coconut Oil, Centella Asiatica Extract, Sodium Isethionate, Lavandula Angustifolia (Lavender) Oil, Gluconolactone, Tocopherol, Pelargonium Graveolens (Geranium) Oil, Sodium Benzoate, Linalool, Citronellol, Geraniol.
The last three names are fragrance allergens naturally present in the lavender and geranium oils, so the formula is still twenty ingredients.
The unscented bar is the same formula with the lavender and geranium left out, and its own list is printed on its label. It carries no benzyl alcohol anywhere, so it is fragrance-free and essential-oil-free.
Because we prioritize freshness and small-batch production, the list above may occasionally vary from your packaging. The ingredient list printed on your bar always reflects the exact formula inside.

Sodium lauryl sulfoacetate is a sulfoacetate, not a sulfate. The scented bar is lightly scented with lavender and geranium essential oils. Choose your option at checkout.
Why there is water in a bar
Aqua sits third on the list, which surprises people who expect a bar to be dry. Some of it is what the surfactants arrive in, and some is added during the pour so the bar sets the way it should. Water is also why the bar is preserved, with gluconolactone and sodium benzoate. A bar that sits wet in a shower needs a preservative, and we would rather name ours than leave it out and hope.
What you notice
- In handFirm and smooth, with a little give at the surface once it is wet.
- LatherCreamy and low-foam. It builds slowly and stays close to the scalp.
- While you washCushioning. Hair feels slippery rather than squeaky.
- After rinseSoft, with enough slip to comb wet hair through.
- Once drySmooth at the lengths. Movement, without a coated feeling.
How to use it
1
Wet hair and bar
Wet your hair thoroughly and run the bar a few times over your scalp and lengths, or work it between wet hands.
2
Massage into a lather
Massage the creamy, low-foam lather into your scalp with your fingertips rather than your nails. The foam stays low. That is the bar working.
3
Rinse well
Rinse thoroughly with warm water until the water runs clear.
4
Follow with conditioner
Follow with the Hydrate Conditioner Bar through the lengths.
5
Let it dry
Stand the bar on a draining dish out of the shower stream and let it dry fully between washes. This is part of how the bar keeps, so it is worth doing every time.
The other half of the wash
The Hydrate Conditioner Bar is the one for the lengths, where the hair is oldest and the tangles start.
Straight answers about barsBuildup, the transition period, hard water, and whether it goes soft
Most people arrive at a shampoo bar with a bad story about one. Waxy hair, weeks of adjustment, a vinegar rinse they were told was mandatory. Those are fair worries and they have a specific cause, so here are the answers in plain terms.
Will it leave buildup?
No. The film people describe comes from soap, which is alkaline and reacts with the calcium and magnesium in tap water. There is no soap in this bar. It cleanses with sodium cocoyl isethionate at a pH of 4.8 to 5.2, so there is nothing in it that can form that film.
Does my hair have to go through a transition period?
No. Those adjustment weeks belong to soap, while your scalp and your water work through the film above. There is no film here, so there is nothing to wait out. The first wash is what the bar does.
Do I need an apple cider vinegar rinse?
No. An ACV rinse exists to bring alkaline soap back down the pH scale. This bar already sits at 4.8 to 5.2, so a rinse has nothing to correct. Use one if you like how it feels on your hair. You do not need it to make this bar work.
Will it strip my hair?
Washing removes oil, and that is what washing is for. The question is how much and how roughly. There are no sulfates and no soap in this bar, and squalane, cocoa butter and kokum butter go through the wash with it, so hair feels cushioned rather than tight.
Is sodium lauryl sulfoacetate a sulfate?
No, and the name is the reason people ask. Sodium lauryl sulfoacetate is a sulfoacetate. Sodium lauryl sulfate is a sulfate. They read alike and behave differently: the sulfoacetate is a larger molecule that stays on the surface of the hair and scalp, where the sulfate is small enough to penetrate. That is the difference behind the sulfate-free claim.
Why is there so little lather?
Foam and cleansing are two different things. These surfactants were chosen for how gently they wash rather than for how much they foam, so the lather stays creamy and low. Your hair is getting clean at that lather.
Will it work in hard water?
Yes. Hard water is a problem for soap, for the reason above. The cleansers in this bar do not react with hard water minerals, so the bar washes and rinses the same way whatever comes out of your tap.
Is it gentle enough for colour-treated hair?
The two things that matter for colour are sulfates and pH. This bar has no sulfates and sits at 4.8 to 5.2, which is the acidic side. We have not run colour-fastness testing, so we are not going to tell you it protects your colour. We will tell you exactly what is in it, and you can decide.
Will the bar go soft?
This bar was reformulated to be harder. That was the point of the change, because a bar that softens in the shower is the thing people give up on. The fat phase was rebuilt around stearyl alcohol, which melts higher than the alcohol it replaced, so the bar holds its shape at shower temperature.
It still needs to dry. Stand it on a draining dish out of the shower stream and it will stay firm. A bar left sitting in water softens whatever it is made of.
How many washes will I get?
That depends on your hair length, how often you wash, and whether the bar dries out between times. We have not printed a wash count, because ours would not be yours.
Allergens and sensitivityEvery ingredient named, and who each one matters to
I formulate for skin that reacts to almost everything, including my own. So I build for less, and I name all of it. Here is everything in the bar, written for anyone with a specific allergy.
Coconut-derived materialsAcross the whole cleansing system
Sodium cocoyl isethionate, caprylyl/capryl glucoside and hydrogenated coconut oil are all coconut-derived. Coconut runs right through the cleansing system rather than sitting in one line, so anyone avoiding it should know that before reading further.
AquaThird on the list
Water is what makes a preservative necessary. The system here is gluconolactone and sodium benzoate, and there is no benzyl alcohol anywhere in this bar.
Cocoa & Kokum Seed ButtersTree-derived
Both are tree-derived, named here for anyone with a specific tree allergy.
Centella Asiatica ExtractApiaceae family
In the Apiaceae family, alongside carrot and celery.
TocopherolNon-GMO · sunflower-derived
A light sunflower and ragweed (Asteraceae) consideration for anyone watching that family. Never soy.
SqualaneSugarcane-derived
Sugarcane rather than olive, so there is no olive in the bar.
Lavender & Geranium OilsScented bar only
They bring linalool, citronellol and geraniol, which are named in the ingredient list for that reason. The unscented bar carries none of them.
This is a reformulated barWhat is no longer in it
The previous version contained colloidal oatmeal, coconut milk, marshmallow root, and ylang ylang oil. None of those are in it now. If you bought the old bar for the oat, or avoided it because of the oat, please read the list above.
That is everything in the bar. Nothing hidden, nothing implied. If a particular ingredient gives you pause, patch test a small area first. You know your body best.
Community accessIncluded free with your purchase

Please note
Formulated for reactive, easily-overwhelmed skin. We suggest a patch test on the inner forearm, left 24 hours, before wider use.
For external use only. Keep out of the eyes, and rinse with water if contact occurs. Stand the bar on a draining dish and let it dry between uses. If irritation occurs, discontinue use.
