L'Oréal Professionnel is the professional arm of L'Oréal Group — the world's largest beauty company — and one of the most iconic professional haircare brands in history. Founded in France in 1909, L'Oréal Professionnel has been at the forefront of professional colour and haircare innovation for over a century, developing many of the technologies that the entire industry relies on today.
The brand's professional product portfolio spans colour systems (Majirel, INOA, Dia Light), care collections (Serie Expert, Metal Detox), and treatment services. The Serie Expert line covers virtually every hair concern from moisture and repair to curl care and scalp health — each with its dual-action Pro-Keratin + Incell technology.
At ProHair.ca, L'Oréal Professionnel Serie Expert represents one of the most accessible yet genuinely professional care ranges we carry. It's a brand trusted by thousands of Canadian salons and delivers consistent, reliable results for every hair type.

Frequently Asked Questions
What is Pro-Keratin + Incell technology?
Pro-Keratin + Incell is L'Oréal Professionnel's dual-action technology: Pro-Keratin reinforces the outer cuticle layer while Incell strengthens the inner cortex. Together, they build hair health from inside out.
What is Metal Detox and who needs it?
Metal Detox was developed after L'Oréal research found that metal deposits (copper, iron) in hair from water and colour build up over time, causing unexpected damage during subsequent colour or bleach. Metal Detox removes these metals before colour services to prevent breakage.
Is L'Oréal Professionnel better than Matrix?
Both are excellent brands owned by L'Oréal Group. L'Oréal Professionnel is the premium professional tier, positioned higher than Matrix. L'Oréal Pro has more technical colour systems and premium care lines. Matrix is the accessible professional tier with a broad range. Both are excellent — choice often depends on budget and desired outcome.
Which Serie Expert line is best for everyday colour care?
Vitamino Color is ideal for everyday colour care — it protects vibrancy and provides UV defense. For very dry colour-treated hair, Absolut Repair is the stronger repair option.
