About this product
Uso Obrigatório Shampoo
Mandatory use, as the name says: TRUSS's Uso Obrigatório shampoo cleanses brittle, dehydrated hair gently with monoi oil while Nano Reconstruction rebuilds the fibre and leaves a lasting protective film, as the first step of the reconstruction routine.
Uso Obrigatório means "a must" in Portuguese: it is TRUSS's line for damaged, dry hair, with immediate reconstruction, deep hydration and protection from everyday damage. Its floral-fruity scent comes with a technology that keeps releasing fragrance through the day on contact with the air.
The new Uso Obrigatório shampoo cleanses brittle, dehydrated hair gently and effectively. Enriched with monoi oil, it brings immediate reconstruction, a shield against damage, flexibility and softness, while Nano Reconstruction penetrates deep into the cuticle and rebuilds the fibre by forming a long-lasting protective film. With the full Uso Obrigatório routine, up to 87% less breakage (compared with hair washed with a shampoo without conditioning agents).
Why you'll love it
- A gentle cleanse for brittle, dehydrated hair
- Immediate reconstruction from the first wash
- Less frizz, less breakage and colour that fades less
- A floral-fruity scent that keeps releasing through the day

Frequently asked questions
Which products complete the Uso Obrigatório routine?
After this shampoo, spray the TRUSS Uso Obrigatório Reconstructor Spray, then use the TRUSS Uso Obrigatório Conditioner or, 1 to 3 times a week, the TRUSS Uso Obrigatório Hair Mask. Finish with a few drops of the TRUSS Uso Obrigatório Reconstructing Hair Oil.
Do I need the whole line to see results?
It works on its own from the first wash. The up-to-87% reduction in breakage is measured with the shampoo, reconstructor and conditioner or mask used together.
Does it contain sulfates?
Yes: sodium laureth sulfate and TEA-lauryl sulfate, which give it a rich lather.
