L'Oreal Professionel

L'Oreal Professionel Serie Expert

A complete haircare system that treats the hair's molecular structure from the core to the surface, delivering high performance results to maintain and preserve beautiful hair between salon visits.

Molecular Precision Technology
Série Expert’s unique molecular precision technology and innovative formulas allow the products to effectively target the three different zones of the hair fiber: the suface, the cuticle and the cortex, which is the very heart of the hair strand.

Zone A - THE SURFACE
This is the external part of the hair, the only part you can actually see. Too much styling or brushing can damage the tiny scales that make up the hair’s surface, which can make it look dull and lifeless. Série Expert works on Zone A to give the hair’s surface enhanced shine and smoothness.

Zone B - THE CUTICLE
The cuticle is made up of inter-cellular cement that holds the scales of the hair strand together. Heat, pollution and other external forces can weaken the hair by damaging those scales. Série Expert targets Zones A and B to help strengthen the hair and increase resistance to everyday aggressors.

Zone C - THE CORTEX
The cortex is at the heart of the hair and is the most important part to care for. It makes up about 90% of the hair fiber and if damaged, can become exposed and weak which leads to breakage. Série Expert targets Zone C and helps to fortify the hair fiber.
