As we age, hair doesn’t just turn grey – it usually becomes thinner, more brittle and duller, too. The right care routine can visually take a few years off, and that’s exactly where the patented hair protection system pH Plex comes in, repairing and stabilizing the hair structure from the inside out. In this article, we pair the ten anti-aging tips from Fudge brand expert Jonathan Andrew with how pH Plex specifically supports each one.
Why does our hair age?
Over the years, hair loses density, elasticity and shine – grey hair also dries out faster, making it look brittle and lacklustre. Chemical treatments such as colouring or bleaching make the problem worse: they raise the hair’s natural pH from a healthy 4.5–5.5 to over 10, roughening the cuticle and causing breakage . It’s precisely this damage that makes hair look older than it is.
What is pH Plex and how does it work?
pH Plex is a globally patented hair protection system made in Germany, based on the natural active ingredient malic acid (INCI: Sodium Malate, Malic Acid), an alpha-hydroxy acid found in all life forms . Unlike many care products, pH Plex works not just on the surface but on a molecular level inside the hair: malic acid bonds to all 21 amino acids of the hair protein keratin and reconnects broken amino-acid bridges like a zipper . At the same time it rebalances the pH, closing the cuticle – the result is more shine and less frizz.
The system consists of three coordinated steps:
- Step 1 – protect: a liquid concentrate mixed into hair colour or bleach to protect the internal hair bonds during chemical treatment.
- Step 2 – repair: a creamy intensive treatment that repairs the hair structure after treatment and restores the natural pH.
- Step 3 – stabilize: a weekly at-home treatment that maintains shine and smoothness between treatments.
The 10 anti-aging tips – and how pH Plex complements them
The following ten tips are based on the recommendations of Fudge brand ambassador Jonathan Andrew, complemented by the targeted use of pH Plex.
1. Regular trims and high-quality care
Regular trims and high-quality care products are the foundation of healthy-looking hair. As a weekly at-home treatment, pH Plex Step 3 strengthens hair from within and reduces the breakage that forces extra trims.
2. Refresh colour with darker tones
A slightly darker tone adds shine in autumn and looks more youthful. If you colour, mix pH Plex Step 1 (4 ml per 30 g of colour) directly into the formula – with no colour shift or extended processing time, as the pH is precisely matched.
3. The right anti-aging cut (the bob)
A versatile shoulder-length bob is considered the ideal anti-aging cut because it can be worn curly, straight or wavy. To help the cut hold its shape, pH Plex provides a stable, elastic hair structure with defined bounce.
4. Less is more when styling
In winter, hats and scarves mess up product-heavy hair, so rely on a primer before blow-drying rather than lots of hairspray. pH Plex strengthens from within, without weighing hair down with heavy silicone layers.
5. A trendy fringe for a fresh face
A slightly longer fringe can be styled flexibly and creates a youthful, fresh look. Smooth, shiny hair – supported by the weekly pH Plex 3 treatment – makes a fringe fall more elegantly.
6. Styling products as make-up for the hair
A shine spray or serum polishes lengths and ends, because healthy hair looks younger. Since pH Plex closes the cuticle through pH balance, the shine comes from the hair itself – the serum only amplifies the effect.
7. A leave-in after every wash
Grey hair dries out quickly, so a nourishing leave-in spray after every wash is recommended. Interestingly, the manufacturer says pH Plex 1 & 2 can also be used as a leave-in to refresh dull hair after colouring.
8. Experiment with your hairstyle
Relaxed styles such as a messy bun or braid instantly look younger. Resilient, breakage-resistant hair – a core effect of strengthened amino-acid bridges – holds up better to such styling.
9. Silver shampoo for grey and bleached hair
Silver shampoos neutralize unwanted yellow and brassy tones and give grey an elegant look. As a complement, the weekly pH Plex 3 treatment stabilizes the structure stressed by bleaching.
10. Heat protection, moisture and hair oil
Heated indoor air and frequent blow-drying stress the hair – heat protection, a moisturizing shampoo and a little hair oil on the ends all help. pH Plex is heat-reactive and provides additional protection against heat-styling damage while preserving shine despite intense heat.
pH Plex even without colouring: the intensive treatment
A common misconception: pH Plex doesn’t only work in combination with hair colour . For a standalone intensive treatment (“Fortissimo application”), mix Steps 1 and 2 in a bowl, apply to damp hair, leave on for 5–10 minutes and rinse out with warm water. This treatment is especially suited to heat-stressed, dry or brittle hair – exactly the issues that characterize ageing hair.
pH Plex for every hair type
According to the manufacturer, pH Plex is suitable for every hair type – from fine to curly, natural to chemically treated .
| Hair type | Benefit of pH Plex | Application tip |
|---|---|---|
| Fine hair | Strengthens from within without weighing down, more volume and elasticity | 1 sachet of Step 3 weekly, optionally shampoo again |
| Curly hair | More bounce, less frizz, more stable curl shape | Gently squeeze curls after rinsing, don’t rub |
| Coloured/bleached hair | Protection during colouring, longer-lasting colour intensity | Always mix Step 1 into the colour, never apply neat |
pH Plex vs Olaplex: the difference
Both systems repair damaged hair from within, but rely on different active ingredients and approaches .
| Aspect | pH Plex | Olaplex |
|---|---|---|
| Core active | Malic acid (Sodium Malate) | Bis-Aminopropyl Diglycol Dimaleate |
| Mechanism | Bonds to all 21 amino acids, pH control | Repairs broken disulfide bridges |
| At-home use | All steps available | Mainly No. 3; No. 1 & 2 usually in-salon |
| Special feature | Natural active, fragrance-free, vegan | Established market leader |
| Price | More affordable | Higher-priced |
Conclusion
Anti-aging for hair is mainly about preserving shine, strength and elasticity – through cut, colour, styling and, above all, high-quality care. pH Plex complements each of these tips by repairing hair on a molecular level, balancing the pH and stabilizing its natural structure – whether as protection during colouring or as a standalone intensive treatment for stressed, more mature hair.
