L'Oréal

Q: What's the difference between L'Oréal Paris and L'Oréal Professionnel?

Same parent company, different channel and different formulation strength. Professionnel is made for salon use — that's why the shampoos come in 1500ml and the colour comes as numbered shades rather than boxed kits.

Q: How do I read a L'Oréal hair colour number?

Depth before the point, tone after it. 1 is black, 10 is lightest blonde; the tone digits tell you the reflect. If you're colouring at home and unsure, the tone is the part to ask a stylist about.

Q: Which L'Oréal shampoo for hair damaged by bleach?

Absolut Repair Molecular, ideally after the Molecular pre-treatment. Add Metal Detox if you're on hard water.

Q: Is Série Expert worth it over supermarket shampoo?

For chemically treated hair, usually yes — the concentrations and the bond-repair chemistry are genuinely different. For healthy untreated hair the gap is much smaller than the price difference suggests.

Q: Do you have L'Oréal makeup or Revitalift?

Not in this collection — it's L'Oréal hair. For makeup see Makeup, and for facial skincare Skincare.

L'Oréal Professionnel salon haircare and colour, including Majirel hair colour by shade number, Absolut Repair and Molecular for damaged hair, and Metal Detox for colour and bleach.
