In the hairdressing trade, staff costs account for roughly 57 percent of turnover, while the net profit margin sits at only around 7 percent — which makes chair time the single most decisive lever for salon profitability. Industry reports confirm that rising wages and competitive pressure continue to squeeze margins, so every avoidable idle minute directly erodes earnings. Even small process steps — fetching supplies, mixing formulas, re-checking pH — can add 10 to 15 minutes per appointment, a cost that hits discount and premium salons alike.
The Hidden Time Killer: Extra Processing Times in Classic Bond Builders
Many competing bond builders on the market either require an adjustment of the oxidant, a reformulation of the colour mix, or additional processing time because their pH formulation deviates from the natural chemical environment of the colour or bleach. This mismatch can cause colour shifts and slows down the salon workflow, adding several minutes to every service. Extrapolated across 8 to 12 colour services per day, this represents a substantial loss of productive capacity at the styling chair.
pH 9.0 – Perfectly Matched to Colour and Bleach
pH Plex 1 is the only plex product worldwide formulated at pH 9.0 — exactly matching the typical pH environment of hair colour and bleach. Because bleaches operate in the pH 9 to 12 range and hydrogen peroxide only oxidises reliably in an alkaline environment, pH Plex 1 slots seamlessly into the existing formulation without any chemical interference. The result: no colour shift, no extended processing time, and no disruption to the salon’s established workflow.
Application Without Losing a Single Minute
pH Plex 1 (Protect) is added directly to the finished bleach or colour mixture — one sachet or one pump stroke (2 ml) per 30 g of prepared bleach paste. The processing time and temperature of the bleach must not and need not be changed, because the concentrate keeps the pH of the mixture stable. Step 2 (Repair) then lowers the pH to around 5.0 and seals the cuticle, with a moderate processing time of just 5 to 10 minutes.
The Economic Impact: More Clients Per Day
If a competing plex system adds even 10 minutes of extra processing time per colour service, six daily colour appointments already translate into a full hour of unused chair capacity. With an average salon turnover of around EUR 125,000 per year and a profit margin of roughly 19 percent, that hour feeds straight into free cash flow. With pH Plex 1 the workflow stays identical to the familiar colour process — so the salon effectively gains capacity without any additional effort.
Chair Utilisation Example
| Scenario | Time per colour service | Services / 8 hours | Additional capacity |
|---|---|---|---|
| Competitor plex with +10 min processing | 70 min | 6.9 | – |
| pH Plex 1 with no extra time | 60 min | 8.0 | +1 client/day |
One extra client per day and chair, across 250 working days, equates to 250 additional services per year — at an average of EUR 100 per colour treatment, a meaningful revenue lever.
Quality Without Compromise
Alongside the time savings, pH Plex binds all 21 amino acids of keratin, whereas classic systems such as Olaplex only address cysteine. The scientific foundation is provided by the proteomics study by Adav et al. (2025) in the Journal of Cosmetic Dermatology, which clearly documents the protection against alkaline damage. Stylists therefore benefit twice over: higher chair utilisation and demonstrably better hair quality for the client.
Takeaway for Salon Owners
Anyone looking to scale colour revenue needs a bond builder with uncompromising pH compatibility — because every extra minute of processing time costs real money. pH Plex 1 integrates seamlessly into the existing workflow, changes neither the oxidant nor the formulation, and enables measurably more clients per day with the same team size.
