Salon-exclusive since 1909 — Serie Expert, Metal Detox and Tecni.Art.

L'Oréal Professionnel is the salon division of L'Oréal Group, founded in Paris in 1909 by the chemist Eugène Schueller — the company began as a hair-colour business and has been developing professional colour and care technology ever since. In Canada it is a salon-exclusive brand, and ProHair.ca is an authorized retailer.

What we stock here is the professional care and styling side of the brand. Serie Expert is the core care system, split by concern: Absolut Repair and Absolut Repair Molecular for damage, Vitamino Color and Vitamino Color Spectrum for colour, Curl Expression for curls and coils, Scalp Advanced for the scalp, Serioxyl Advanced for thinning hair, Pro Longer for long hair and worn ends, Liss Unlimited for frizz, Blondifier and Silver for blonde and grey, and Inforcer for breakage. Alongside it sit Metal Detox — the range built around L'Oréal's Glicoamine molecule, which targets metal particles left in hair by tap water — and Tecni.Art, the professional styling line.

Almost every Serie Expert shampoo, conditioner and mask is sold in more than one size on this page: a retail bottle, a 500 ml, a 1.5 L back-bar litre and, on several lines, a 500 ml or 1 L eco-refill pouch. Those are the same formula at a very different price per millilitre, which is the single biggest way to buy this brand well. We also carry the Steampod 4.0 steam straightener and the AirLight Pro dryer.

Absolut Repair & Absolut Repair Molecular

Absolut Repair & Absolut Repair Molecular

The two damage-repair systems, and they are not the same thing. Absolut Repair resurfaces the outside of the fibre with protein and gives instant softness. Absolut Repair Molecular is sulfate-free and works with a peptide bonder that re-links broken bonds inside the fibre — it is the one for bleached and severely compromised hair, and it comes with a leave-in mask and a pre-treatment.

Metal Detox

Metal Detox

Built around Glicoamine, a small molecule that targets the metal particles tap water deposits inside hair — the reason colour can go dull and bleach can break hair unexpectedly. The shampoo, mask, leave-in cream, concentrated oil and professional pre-treatment spray all work on the same principle. Use it before a colour service and as everyday maintenance if your water is hard.

Vitamino Color & Color Spectrum

Vitamino Color & Color Spectrum

Vitamino Color is the everyday colour-protection system with resveratrol and UV filters. Vitamino Color Spectrum is the newer, higher-shine tier — it adds a Glass Shine serum, a richer mask, and a purple shampoo that neutralises brass on blonde and highlighted colour. Both run from a 300 ml retail bottle up to a 1.5 L litre.

Curl Expression

Curl Expression

A full curl system rather than a single cream. Two different cleansers — a Moisturizing Cleansing Cream for dry curls and an Anti-Residue Cleansing Jelly for build-up — then a Moisturizing Mask for waves and looser curls or a Rich Moisturizing Mask for coils, plus the 10-in-1 Cream-in-Mousse, the Curl Activator Jelly and the Curl Reviver water mist for day-two curls.

Blondifier & Silver

Blondifier & Silver

Two different blonde jobs. Blondifier is the care line for lightened and highlighted hair — the Gloss shampoo, mask and a 400 ml Rinse Treatment lamination for gloss. Silver is the neutralising purple line for grey, white and silver hair, in shampoo and conditioner. If your goal is toning rather than care, Silver or the Spectrum Purple Shampoo is the one you want.

Scalp Advanced & Serioxyl Advanced

Scalp Advanced & Serioxyl Advanced

Scalp Advanced treats the scalp as skin: an Anti-Oiliness dermo-purifier with a clay masque, an Anti-Discomfort dermo-regulator for sensitivity with an Intense Soother leave-in, and an Anti-Dandruff dermo-clarifier. Serioxyl Advanced is the density range — a thickening shampoo and the Denser Hair Serum, also sold as a 3-month program.

Pro Longer, Inforcer & Liss Unlimited

Pro Longer, Inforcer & Liss Unlimited

Three targeted Serie Expert lines. Pro Longer uses amino acids and lemon extract to rebuild thin, worn ends so length looks fuller — with a 400 ml Rinse Treatment lamination and a 15 ml Ends Filler ampoule. Inforcer is the anti-breakage line with biotin for fine hair that snaps. Liss Unlimited is the anti-frizz smoothing system, with a primrose-oil blow-dry oil.

Tecni.Art

Tecni.Art

The professional styling line, 14 products deep here and all at one simple price.

Frequently Asked Questions

What is the difference between Absolut Repair and Absolut Repair Molecular?
They repair in two different places. Absolut Repair works on the surface of the hair — protein and a resurfacing complex that smooth the cuticle, so hair feels soft immediately. Absolut Repair Molecular is sulfate-free and uses a peptide bonder to re-link broken bonds inside the fibre, which is a slower, structural repair. If your hair is dry and rough, Absolut Repair is enough. If it is bleached, elastic when wet, or breaking, go Molecular — and use the Rinse-Off Serum or the Leave-In Mask with it, because the line is designed as a system.
Do I actually need Metal Detox, or is it marketing?
It depends on your water. L'Oréal's research found that copper and iron from tap water accumulate inside the hair fibre, and that those metal particles react during colouring and bleaching — which is why the same formula can behave differently on two clients. Metal Detox uses Glicoamine to target them. If you are on hard or well water, if your colour goes dull faster than it should, or if you are about to have a lightening service, it is worth it. If you are on soft municipal water and do not colour, you can skip it.
Is the 1.5 L back-bar bottle the same product as the retail bottle?
Yes — same formula, salon packaging, no pump included. On most Serie Expert lines the 1.5 L costs roughly the same as two 500 ml bottles while holding three, so it is the cheapest way to buy a shampoo you use daily. Buy the matching pump separately: we stock a 1.5 L pump, a 750 ml conditioner pump, and a 750 ml/1 L pump. If you go through less than about a litre a year, the 500 ml is the more sensible buy — an opened litre sitting for two years is not a saving.
What are the refill pouches, and are they worth it?
Several lines — Absolut Repair, Absolut Repair Molecular, Metal Detox and Vitamino Color Spectrum — now come as a 500 ml or 1 L eco-refill pouch. It is the same shampoo in a flexible pouch instead of a rigid bottle, meant to be poured into the bottle you already own. They cost less per millilitre than the equivalent bottle and use far less plastic. The only catch is that you need an empty bottle to decant into, so buy the bottle first and the pouch after.
Which purple product should I use — Silver, Blondifier or Spectrum Purple Shampoo?
Silver is the neutralising line for grey, white and silver hair, and it is the strongest toner of the three. Vitamino Color Spectrum Purple Shampoo is for blonde and highlighted colour that is going yellow, and it doubles as colour care. Blondifier is not primarily a toner at all — it is the care and gloss line for lightened hair, so use it when blonde is dry and dull rather than brassy. Purple only cancels yellow; if your problem is orange, you need a blue toner, which this brand does not make in retail care.
Is Serie Expert sulfate-free?
Some of it. Absolut Repair Molecular is sulfate-free, and so are the Curl Expression cleansers. Most of the other Serie Expert shampoos are not. L'Oréal Professionnel does not build the range around a sulfate-free claim — it formulates for the concern instead. If sulfate-free matters to you, Molecular and Curl Expression are the two lines to look at, and the Curl Expression Anti-Residue Cleansing Jelly is the one clarifying wash in the range.
How does L'Oréal Professionnel compare to Kérastase and Matrix?
All three are L'Oréal Group brands at different tiers. Matrix is the accessible professional tier, L'Oréal Professionnel sits above it, and Kérastase is the luxury tier sold through a smaller set of salons. In practice L'Oréal Professionnel is the technical middle — the same laboratory research as Kérastase, in bigger bottles at a lower price per millilitre, with a much wider back-bar range. If you want a litre of a genuinely professional shampoo, this is the brand to buy it in.
Is ProHair.ca an authorized L'Oréal Professionnel retailer?
Yes. We have supplied Canadian salons and stylists since 1996 and source L'Oréal Professionnel through authorized Canadian distribution, so every bottle is current Canadian stock with Canadian labelling — not grey-market or expired inventory. Orders ship from Canada with free shipping over $120.
