you are not giving up your shampoo. same liquid, poured the same way - only the bottle changes.

THE CLEANSER

Sodium cocoyl isethionate

made from coconut fatty acids. Aveda uses the same one instead of sulfates.

IN THE CURLS FORMULA

  • flaxseed
  • quinoa proteina hydrolysed plant protein
  • guarguar gum, made cationic. hair's surface is negatively charged.
  • glycerina humectant, which means it holds water. the most used moisturising ingredient in cosmetics.

most shampoos are more alkaline than your hair. in one study, 62 of every 100 tested were above 5.5. above that, the surface of the hair roughens and strands catch on each other. this one is 5.0 to 5.2.

NOTHING ELSE

  • sulfates
  • parabens
  • silicones
  • microplastics
  • plastic

how it works

POUR IT OUT

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.

WASH YOUR HAIR

2 · WASH YOUR HAIR

Exactly as you always have. The shell goes back on the shelf between washes, still full.

THEN WASH WITH THE SHELL

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.

the scent is the soap. the shampoo inside smells of what it's made of.

HOW IT FEELS

A dense, creamy lather from a solid marble shell. Hair first, then the bottle becomes your body soap. 200 ml · a full bottle of shampoo, plus the soap it comes in, about 50 washes at 4 ml. Shell and shampoo are designed to run out together.

WHAT THEY SAID ABOUT IT

  • 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

  • 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

  • Really happy with this shampoo. It lathers nicely, smells good and my hair feels fresh after washing. Will definitely get another one.

  • 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.

i took sapone to shark tank at 17. walked out with a deal.
