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.
Why Buy From ProHair?
ProHair.ca is an authorized Canadian L'Oréal Professionnel retailer. We carry the complete Serie Expert collection with free shipping over $99.99.
