Strengthening Routine - In&Out
Discover the Fortifying Protocol, specially formulated to strengthen the hair fibre and protect hair from external aggressors.
This complete protocol helps to reduce breakage while revealing hair that is stronger and visibly healthier.
The Strengthening Shampoo gently cleanses hair thanks to its delicate lather, without a rough feel.
The Fortifying Conditioner instantly detangles hair and improves its slip without a greasy finish.
The Fortifying Serum coats lengths without weighing them down and provides suppleness and softness.
Thanks to a dual ex vivo & in vivo study, the Fortifying Protocol helps make hair up to 64x more resistant and reduces brushing-related breakage by up to -60%*. Hair appears stronger, more resilient and better protected day after day.
Tested and approved, it acts as a true protective shield for the hair fibre while providing softness, hydration and lightness to hair.
