Both ranges target severely damaged hair, but they work at different structural levels. Absolut Repair (Série Expert) delivers intense surface repair with proteins and gold quinoa, restoring strength, texture, and shine. Absolut Repair Molecular goes deeper, rebuilding broken internal bonds at a molecular level — making it the recommended choice for hair that has undergone repeated chemical services or extreme mechanical damage.

For clients experiencing hair thinning and hair fall, Serioxyl is the dedicated L'Oréal Professionnel solution — it densifies the hair fibre and prolongs the hair growth phase. For broader scalp concerns such as excess oiliness, dryness, or sensitivity, Scalp Advanced (Série Expert) offers targeted protocols for each scalp profile, restoring balance without compromising hair quality.

Metal Detox (Série Expert) is specifically formulated to neutralise metal accumulation within the hair fibre — a primary cause of colour deviation and breakage during chemical services. It can be used as a pre-service treatment before a colour or bleach service to stabilise the formula, and as an at-home maintenance system to protect colour longevity between appointments.

Vitamino Color Spectrum (Série Expert) Professional Purple Neutralizing Shampoo is your everyday brass-buster — formulated specifically to counteract unwanted yellow undertones on blonde or pre-lightened hair. It combines purple dyes with caring agents: the professional-tailored purple dyes neutralize and color-correct undesired yellow undertones, while the range's caring agents help maintain hair's condition.

L'Oréal Professionnel offers two options within its colour care portfolio. Vitamino Color (Série Expert) shields the cuticle with antioxidant complexes to prevent colour fade, protecting vibrancy for up to 8 weeks — suitable for all colour-treated hair. Vitamino Color Spectrum, the more advanced formula, uses Ferulic Acid and Citric Acid (2.5%) to lock in "glass shine" and maintain vibrancy across five dimensions — shine, vibrancy, contrast, tone, and brightness — for up to 100 days, making it the go-to upgrade recommendation for longer-lasting results.

Curl Expression (Série Expert) is L'Oréal Professionnel's dedicated range for wavy, curly, and coily hair. It combines intense hydration with frizz control and definition, adapting to varying curl textures. The range includes a rich cream-in-shampoo, a lightweight leave-in hydrator, a long-lasting intense moisturising cream, and a defining gel — allowing stylists to build a customised curl ritual for each client.

Serioxyl Advanced Densifying Shampoo (Série Expert) is engineered specifically for fine, flat hair that is linked to thinning. Its lightweight formula leaves hair densified and more volumious. For styling options, the L'Oréal Professionnel Tecni.Art volume range includes mousses and sprays designed to lock in root lift after a blow-dry service.

Liss Unlimited (Série Expert) delivers long-lasting smoothness and anti-humidity protection for unruly, coarse, or frizz-prone hair. Keratin Alpha Sleek (Série Expert) transforms hair for up to 2 weeks of smooth, frizz- and volume-controlled results, delivering long-lasting smoothness while preserving hair integrity. It controls frizz and volume for a sleeker, more manageable finish, with instant shine. For clients seeking a more transformative in-salon treatment, X-tenso Moisturist — the L'Oréal Professionnel permanent smoothing system — provides up to six months of sleek, aligned hair, with dedicated at-home maintenance products to prolong the result.

The SteamPod 4 is L'Oréal Professionnel's professional steam straightener, designed to smooth and style with precision while minimising heat damage. It works in synergy with the Steampod Smoothing Milk and Steampod Smoothing Anti-Frizz Treatment, which provide thermal protection and a polished finish. For everyday heat protection across all hair types, the Tecni.Art All-in 1 Performer and Pro Longer styling lines includes dedicated thermal protectors suitable for use with all heat tools.
