The format
How it works
A weighted vessel you buy once. Concentrate refills you buy forever.
01 — Buy the vessel once
Heavier than it needs to be, because weight is the argument.
- Size
- 180 × 62 MM
- Body
- Borosilicate laboratory glass
- Collar and base
- Brushed 316 surgical steel
- Price
- $65, once
02 — Refills come by post
Slim enough to post through a letterbox. No courier, no box.
- Vial
- 30 ML aluminium
- Size
- 95 × 26 MM
- Mailer
- Flat paper sleeve, batch number only
03 — Mix it
Pour to collar. Fill to line. Shake once.
The instruction is the object: one line, etched into the glass at 200 ml.
- Concentrate
- 30 ML
- Water
- 170 ML
- Makes
- 200 ML
04 — Use it
About two months. Then the next vial.
Use no more than two products at once. More actives means more irritation, not more result.
05 — What to throw away
Most shampoo is water. You already have water.
- Vial
- Metal recycling
- Sleeve
- Paper recycling
- Tissue, stickers, sachets
- None sent
- Refill weight
- 40 G, not 400
- Conventional shampoo
- 80% water
Start with the vessel.
