What is reverse shampoo ?
Reverse shampooing involves applying a treatment to the lengths of the hair before shampooing, then washing over it. The idea is not to add more nourishment, but to create a protective layer between the hair fiber and the shampoo, and to rinse away the excess instead of letting it weigh down the hair.
- The treatment is applied to dry or damp hair, before washing.
- It is then washed off by the shampoo, not rinsed out on its own
- The method is also called pre-poo or pre-shampoo oil bath
Reverse shampooing isn't exactly revolutionary: it's simply a pre-shampoo oil treatment with an English name. What interests me is that it addresses a real problem—fine hair weighed down by conditioners. But when applied to very dry hair, it deprives it of the care it truly needs.
Who is reverse shampoo suitable for?
It's designed for fine, flat hair that quickly becomes weighed down and loses all volume as soon as conditioner is left on the lengths. It's also suitable for oily hair with roots that get greasy quickly, and for those who enjoy oil treatments but struggle to rinse them out properly. On thick, very dry, or porous hair , the method is counterproductive: the shampoo removes some of the conditioning the hair fiber needed.
How do you do a reverse shampoo?
The protocol consists of three parts:
- Apply the treatment to the lengths and ends only, never to the roots
- Leave on for ten to twenty minutes, on dry or slightly damp hair
- Then wash with a pH 5 shampoo, massaging the scalp with your fingertips.
- Rinse thoroughly with lukewarm water, without applying any further skincare products afterwards.
- Untangle on damp hair, points towards the roots
A conditioner is still possible at the end of the routine if your hair needs it — but in that case, reverse shampooing doesn't add much.

"Impressive. I've only been using it for a month and I'm shocked: the scent is divine, the texture perfect. And from the very first application, my hair is thicker, fuller, and stronger."

Discover the solutionLe protocol for fine hair that retains volume
Reverse shampooing addresses a symptom— weighed-down lengths—but volume is primarily achieved at the roots. The scalp is exfoliated to remove the sebum that weighs down the roots, a pH-5 wash is used with a formula designed for fine hair , and rich treatments are reserved for the ends. In this respect, reverse shampooing becomes a comfort adjustment rather than a quick fix.
