Metal Detox Pre-Shampoo by L’Oréal Professionnel is designed to treat the hair from vulnerability to water and metals including chemical processing, heat styling & UV exposure.

Enriched with patented 2% Glicofiller technology, this intensive pre-shampoo treatment coats the fibre and refills micro-breaks both on the surface and deep inside the cortex, preventing the excess absorption of copper found in water.

Hair feels intensely moisturised & plumped so that even the most porous, damaged hair feels incredibly soft, smooth, and full-bodied.

This lightweight, concentrated gel with a fresh citrus & musky wood scent requires zero development time, layering directly under shampoo to eliminate an extra rinsing step and limit water consumption.

The results deliver:

• Refills up to 1 million hair micro-breaks in 1 use¹
• Anti-porosity protection²

Up to:

• 99% less hair breakage in 1 use³
• 72 hours of nourishment, smoothness & softness⁴

Separate wet hair into two sections. Work the product through the lengths and ends for 1-2 minutes until a light lather appears - do not rinse. In a layering technique, apply the Metal Detox Shampoo directly over the top. Then, rinse and follow with the routine.
