Professional Hair Treatments 2026: The 5 Protocols to Offer in Your Salon
Professional hair treatments 2026 are emerging as a genuine differentiator for salons across French-speaking Switzerland. Between the new acidic treatments rich in disulfide bonds, the boom of the glossy lived-in routine, and client demand for clean beauty formulas, the in-chair treatment offering has been completely reinvented. These professional hair treatments 2026 are no longer simple extras billed in passing: they are becoming a standalone service, valued between 35 and 90 CHF depending on the protocol. This guide presents the 5 major families of professional hair treatments 2026 to add to your salon menu, with protocols, reference brands, and real profitability for a Swiss salon.

Why professional hair treatments 2026 change everything in the salon
A salon that doesn’t offer a structured treatment menu is today missing out on 20 to 30% in additional revenue. Clients aged 25-50, the main profitable segment, arrive in the chair with hair weakened by repeated colouring, balayage, and heat styling tools. They expect a diagnosis, a named protocol, and a visible result. Professional hair treatments 2026 meet this demand with targeted actives: rebuilding disulfide bonds, sealing the fibre, mirror shine. They also drive loyalty: a client who sees the difference after an acidic in-chair treatment comes back every 4 to 6 weeks, sometimes independently of a colour service. Reference groups such as Kérastase or Olaplex publish precise in-chair protocols: an excellent foundation for structuring your offering.
Family No. 1: bond-building treatments
The bond-building treatments within professional hair treatments 2026 remain the go-to reference for repairing fibre damaged by lightening or relaxing. These protocols target the disulfide bonds broken inside the hair and durably rebuild them. The must-have brands: Olaplex N°0 + N°3 in-chair, K18 Peptide Prep, and Wella Plex. Allow 15 to 25 minutes of processing time for a full protocol and an in-chair rate of 45 to 75 CHF, billable on top of the colour service. The client immediately feels a denser touch, hair dries more easily, and colour lasts longer. These professional hair treatments 2026 are essential for any lightening service or light balayage.
Family No. 2: glossy acidic treatments
A major novelty among professional hair treatments 2026: the rise of low-pH acidic treatments (3 to 4) that seal the hair cuticle and create a spectacular mirror effect. Here are the protocols to know:
| Product | Processing time | Main effect | In-chair rate |
|---|---|---|---|
| L’Oréal Pro Metal Detox | 10 min | Neutralises metals, glossy | 35-50 CHF |
| Kérastase Acidic Bonding | 5-10 min | Sealing and shine | 40-60 CHF |
| Redken Acidic Bonding Concentrate | 10 min | Strengthens, glossy | 40-55 CHF |
| Wella Color Motion | 3-5 min | Colour fixation, shine | 30-45 CHF |
The secret of these professional hair treatments 2026: they’re applied in just a few minutes at the basin, without excessively extending service time. It’s an ideal treatment to add systematically to every colour service.
Family No. 3: intensive hydrating treatments
For dry, coily, curly, or simply summer-dehydrated hair, the hydrating treatments among professional hair treatments 2026 bring suppleness and manageability.

The go-to references in-chair: Kérastase Nutritive Masquintense, Davines NouNou, Shu Uemura Essence Absolue. Standard protocol: applied after a technical shampoo, 10 to 15 minutes of processing under a steamer, rinsed with lukewarm water. Recommended in-chair rate: 40 to 65 CHF. These professional hair treatments 2026 are perfect at the start of autumn or the end of summer, periods when demand naturally peaks.
Family No. 4: scalp treatments

Family No. 5: glossy finishing treatments
The last essential family of professional hair treatments 2026: glazes, serums, and finishing oils that seal in the result after blow-drying or styling. These are short treatments (2 to 5 minutes) with very high perceived value that radically transform the client’s final Instagram photo.
