Blonde & colour protection.
What this actually is
Blonde is the most expensive colour to achieve and the most fragile to keep, and both facts have the same cause. Lightening works by opening the cuticle and removing natural pigment from the cortex. What is left is a hair fibre that is structurally more porous than it started — it takes water in faster, loses it faster, and holds toner less well.
Brassiness is the usual complaint and it comes from two directions. Underlying warm pigment gets exposed as the hair lifts, and it becomes more visible as toner fades. Then the environment adds its own: UV oxidises the hair, hard water deposits minerals, and chlorine and iron do the rest. Irish hard water is a genuine factor here, not an excuse.
Purple shampoo is the standard answer and it is routinely misused. It deposits violet pigment to neutralise yellow — it is a toner, not a treatment, and it does nothing for the condition of the hair. Used too often it dulls blonde and can leave a grey or lilac cast on very light hair. Once or twice a week is plenty.
The rest is protection: moisture, bond support, heat discipline and a hat in strong sun.
A routine that suits it
Where we would start. Build it up one step at a time rather than all at once.
- Wash
Colour-safe and sulphate-light, in lukewarm water. Hot water opens the cuticle and toner leaves with it.
What we use - Tone
Purple shampoo once or twice a week, not every wash. It corrects colour, it does not condition.
- Condition
Lightened hair is porous and needs more moisture than it did before, every single wash.
What we use - Seal and protect
An oil on the ends, heat protectant always, and a hat in strong sun — UV is what turns blonde brassy.

Frequently asked
- How often should I use purple shampoo?
- Once or twice a week at most, and less if your blonde is very pale. It deposits violet pigment to cancel yellow — it is colour correction, not conditioning, and using it every wash tends to dull the blonde and can leave a grey or lilac cast. If your hair looks flat rather than bright, you are probably overusing it.
- Why does my blonde go brassy so quickly?
- Three things usually stacking up: warm pigment underneath becoming visible as toner fades, UV oxidising the hair, and minerals in hard water depositing on a porous fibre. Irish hard water genuinely contributes. Cooler water, a UV-aware product in summer and a clarifying wash occasionally will each buy you time between salon visits.
- Is it worth using a bond builder at home?
- For lightened hair, generally yes — it supports the internal structure that lifting weakened, and it is one of the few home products with a real mechanism behind it. It is not a substitute for moisture, though. Blonde needs both: bond support for strength, conditioner for flexibility. Use one without the other and the hair either snaps or goes limp.
