Colour-treated hair — whether you’re bleached blonde, highlighted, balayaged, or freshly dyed — has fundamentally different needs from virgin hair. The colouring process opens the hair cuticle to deposit or remove pigment, leaving strands more porous, fragile, and prone to fading. Use the wrong shampoo and you’ll lose weeks of colour in a single wash.
These are the best shampoos for blonde and colour-treated hair available in South Africa in 2026 — tested for colour retention, brassiness control, and overall hair condition.
Why Regular Shampoo Is the Enemy of Colour-Treated Hair
Standard shampoos contain sulphates (sodium lauryl sulphate or sodium laureth sulphate) — powerful detergents that strip oils from the scalp and hair. For colour-treated hair, sulphates aggressively wash out the artificial pigment molecules deposited during colouring, causing:
- Rapid colour fade — especially with reds, violets, and blue-blacks
- Brassiness on blonde and highlighted hair — as the warm undertones in hair oxidise and the toner washes out
- Increased porosity and dryness — as the cuticle stays raised rather than sealed
- Brittleness and breakage — colour-treated hair is already more fragile at the bond level
The solution: sulphate-free shampoos formulated specifically for colour retention, plus — if you’re blonde — a purple or blue toning shampoo to neutralise brassiness.
Best Shampoos for Colour-Treated Hair in South Africa
1. Redken Color Extend Shampoo
Best for: All colour-treated hair types — the gold standard

Redken Color Extend is formulated specifically for colour-treated hair and remains one of the top-recommended options by South African colourists. The sulphate-free formula seals the cuticle around deposited colour molecules and contains a protein system that repairs bonds weakened by the colouring process. Colour stays true for measurably longer between salon visits.
Key ingredients: Protein complex, colour-extending actives
Sulphate-free: Yes
Best for: All colour types from highlights to all-over colour
2. Schwarzkopf Bonacure Color Freeze Shampoo
Best for: Vivid, vibrant colour that fades quickly
Schwarzkopf Professional’s Color Freeze technology literally “freezes” the colour molecules inside the hair shaft, extending vibrancy and slowing the oxidation process that causes fading. The low-pH formula seals the cuticle shut, locking colour in from every angle. Particularly effective for reds, violets, and fashion colours that notoriously fade fast.
Key ingredients: Color Freeze complex, low-pH formulation
Sulphate-free: Yes
Tip: Rinse with cool water after every wash — heat is colour’s worst enemy
3. OGX Fade Defying + Orchid Oil Shampoo
Best for: Everyday colour protection at an accessible price

OGX Fade Defying is South Africa’s most accessible salon-quality colour-care shampoo. Orchid oil is rich in antioxidants that prevent colour oxidation — the main reason hair goes brassy or dull between treatments — while the sulphate-free formula keeps colour-deposited molecules intact. Lightweight, non-stripping, and safe for daily use.
Key ingredients: Orchid oil, antioxidants, UV filter
Sulphate-free: Yes
Price point: Mid-range
Best Shampoos Specifically for Blonde Hair in South Africa
Blonde and highlighted hair has an additional challenge: brassiness. As artificial toner and gloss wash out, the warm yellow and orange undertones in the hair become exposed, making blonde look dull, yellow, or brassy. A purple or blue toning shampoo deposits tiny amounts of violet pigment to neutralise these warm tones and restore brightness.
4. Redken Color Extend Blondage Shampoo
Best for: Platinum, icy, or highlighted blonde
Redken Blondage is the definitive purple shampoo for blonde hair in South Africa. The ultra-concentrated violet pigment neutralises yellow and brassy tones from the first use — dramatically brightening blonde between salon visits. Use 1–2 times per week (not every wash, as overuse can deposit too much purple). Works on platinum, ash, golden, and highlighted blonde — as well as on grey hair to brighten and remove yellowing.

Key ingredients: Ultra-concentrated purple pigment, protein complex
Sulphate-free: Yes
How to use: Leave on for 3–5 minutes before rinsing. 1–2× per week maximum
5. Schwarzkopf Bonacure Color Freeze Silver Shampoo
Best for: Silver, platinum, and very light blonde hair
Schwarzkopf’s Silver Shampoo is a favourite in South African salons for platinum and silver-toned blonde clients. The silver-enriched toning formula removes brassy, yellow, and orange undertones while simultaneously locking in colour with the Color Freeze system. More intense than most purple shampoos — excellent for platinum and icy blonde but better used once a week only on lighter shades.
Key ingredients: Silver pigment, Color Freeze complex
Sulphate-free: Yes
Best for: Platinum, silver, and ash blonde
6. Joico Color Balance Purple Shampoo
Best for: Golden and warm blonde tones that need gentle brassiness control
Joico’s Color Balance Purple Shampoo is a gentler toning option for blondes who want brassiness control without the risk of over-toning. The SmartRelease technology delivers conditioning argan oil, rosehip oil, and hydrolysed keratin alongside the purple pigment — making it one of the most hair-healthy toning shampoos on the South African market.

Key ingredients: Purple pigment, argan oil, rosehip oil, hydrolysed keratin
Sulphate-free: Yes
Best for: Warm golden blonde and strawberry blonde
How to Wash Colour-Treated Hair to Preserve Colour Longer
- Wait 48–72 hours after colouring before your first wash — the colour needs time to fully oxidise and set inside the hair shaft
- Wash less frequently — every 3 days is ideal for colour-treated hair; daily washing dramatically accelerates fade
- Use cool or lukewarm water only — hot water opens the cuticle and leaches colour out
- Use a colour-protecting conditioner on every wash — and a deep conditioning mask weekly
- Protect from UV exposure — South Africa’s intense sun accelerates colour oxidation significantly
- Rinse thoroughly — shampoo residue left on colour-treated hair traps minerals from SA’s tap water, contributing to dullness and brassiness
How Often Should You Use Purple Shampoo?
For most South African blondes: once or twice a week is ideal. Using purple shampoo every wash can over-deposit pigment and leave hair with a violet or grey cast — particularly on lighter platinum shades. A good routine is: purple shampoo twice a week, colour-protecting sulphate-free shampoo for remaining washes.
If your hair feels dry or brittle after purple shampoo, follow immediately with a deep conditioner. Toning shampoos can be drying — the condition of the hair is as important as the colour.
