how it works

1 · POUR IT OUT
Tip the shell over your hand. What comes out is ordinary liquid shampoo — there is nothing to work into a lather first and nothing to get used to.

2 · WASH YOUR HAIR
Exactly as you always have. The shell goes back on the shelf between washes, still full.

3 · THEN WASH WITH THE SHELL
When the shampoo is gone the shell is a bar of body soap. Leave it somewhere it can drain — it wears down only where water hits it.
THE SCENT
how it smells
creamy, warm and familiar
coconut milk · vanilla pod
Sweet, but not dessert. It lingers a little after the shower and then lets go.

I thought it would melt in the shower
Honestly, I thought the bottle would disappear way too fast. It didn't. I used the shampoo normally and the soap bottle lasted until I was basically done with the shampoo. Such a clever idea.
Emily
They actually ran out together
I was curious to see if this would really work. The shampoo ran out and the soap bottle was basically gone at the same time. No empty plastic bottle left. Pretty satisfying.
Megan
Love it
Love it. The shampoo feels great and I love not having another plastic bottle in my shower.
Sarah
So good
Really nice shampoo. Lathers well, smells great and leaves my hair feeling clean without feeling dry. And the bottle being soap is just genius.
Ashley
Didn't expect this
I bought it because the concept looked cool, but I actually really like the shampoo. It feels like a normal liquid shampoo, which was important to me.
Lauren
The bottle surprised me
I thought the soap bottle would get soft and fall apart in a few showers. It really doesn't. It wears down slowly and mine lasted until the shampoo was almost finished.
Jessica
Such a simple idea
Why are we still throwing away shampoo bottles? This makes so much sense. Good shampoo, nice scent and nothing left to throw away afterwards.
Rachel
I'm impressed
Was honestly expecting the bottle to be more of a gimmick. It isn't. The shampoo is really good and the soap bottle actually works.
Madison
Would buy again
Used the whole bottle and really enjoyed it. Hair feels clean and soft, and I love that there was no plastic bottle at the end.
Taylor
Love the concept
I love this. The shampoo is good, but watching the bottle slowly disappear in the shower is weirdly satisfying.
Olivia
My favorite part
The shampoo is great, but my favorite part is definitely the bottle. You use it as soap and eventually there is literally nothing left.
Hannah
No plastic bottle
This is probably the first shampoo I've bought where I actually looked forward to finishing it. Usually you're left with an empty bottle. Here, you just keep using the bottle as soap.
Katie
Actually works
I was skeptical about the whole soap bottle thing, but it actually works. The shampoo lasts and the bottle doesn't just melt away after a few showers.
Amanda
Very happy with it
Really happy with this shampoo. It lathers nicely, smells good and my hair feels fresh after washing. Will definitely get another one.
Morgan
Simple and smart
Good shampoo. Great idea. No plastic bottle. That's pretty much it.
Brittany
Obsessed
Okay, I love this. The shampoo is great and the bottle disappearing as you use it is such a cool touch.
Nicole
Better than expected
I honestly expected to like the idea more than the actual product. Turns out I really like both.
Samantha
No complaints
Really good shampoo and the bottle is such a smart idea. Would recommend.
Chloe
I need another one
Finished mine and immediately wanted another. That probably says enough.
Courtney
So clever
The fact that the shampoo and the bottle actually run out together is brilliant. No waste and no weird leftover bottle sitting in the shower.
Erin
Just love it
Love the shampoo. Love the bottle. Love that there's nothing left to throw away.
Alexis
My shower looks better
Not going to lie, I mostly bought it because it looked cool. Now I actually want all my bathroom products to come like this.
Kayla
No more shampoo bottles
This is such an easy switch. Same liquid shampoo routine, just without the plastic bottle. I didn't have to change anything.
Mia
Would recommend
Great shampoo, lovely smell and such a clever bottle. Really happy with it.
Jennifer
frequently asked questions
There is an opening under the cap. Tip it over your hand and it pours, the way any bottle of shampoo pours. Nothing to unscrew, nothing to squeeze.
