Philip Kingsley Pure Blonde Booster Colour-Correcting Weekly Shampoo 250ml is a once-a-week purple toning shampoo designed to neutralise brassy yellow and warm tones in blonde, grey, silver, platinum and highlighted hair. Violet micro-pigments cool the tone without leaving a blue or purple tint, while a conditioning base of lavender oil and trace minerals helps protect the hair from drying out — a common pitfall of harsher purple shampoos.
About Philip Kingsley
Philip Kingsley was a British trichologist who founded his eponymous London hair clinic in 1957, working with everyone from Audrey Hepburn to Cate Blanchett. The brand built its reputation on diagnosing and treating scalp and hair concerns rather than simply styling — and the Pure Blonde Booster is a trichology-led take on the now-widespread purple shampoo category.
Key ingredients
- Violet Micro-Pigments (Ext. Violet 2) — the cool toning agent that neutralises brassiness; deposits evenly without staining.
- Magnesium Aspartate, Zinc Gluconate and Copper Gluconate — mineral complex that supports clean tone deposition.
- Lavender Essential Oil — calms the scalp and helps replenish natural oils in dry hair.
- Polyquaternium-10 and Guar Hydroxypropyltrimonium Chloride — conditioning agents that improve combability and shine.
- Decyl Glucoside and Cocamidopropyl Betaine — milder, gentle surfactants that cleanse without stripping.
Key benefits
- Neutralises brassy yellow and warm tones in blonde, grey and silver hair
- Clarifies and brightens the hair, leaving it looking cool, clean and radiant
- Hydrates and conditions — less drying than many purple shampoos
- Suitable for highlighted, bleached, platinum and naturally blonde hair
- Trichologist-developed formulation
Who it's for
Best suited to anyone with blonde, grey, silver, platinum or highlighted hair that is becoming brassy, yellow or warm over time. Particularly useful as a once-a-week toning treatment between salon appointments. Not for daily use — too frequent application can cause an unwanted cool blue or lavender tint, especially on lighter, more porous hair.
How to use
- Wet the hair thoroughly with lukewarm water.
- Apply a generous amount of shampoo and lather into a rich foam.
- Leave on the hair for 1–3 minutes, depending on how brassy the hair is and how cool you want the result.
- For more intense toning, leave for up to 5 minutes — but watch the colour carefully on very pale or porous hair.
- Rinse thoroughly.
- Follow with your usual conditioner. Use once a week alongside your regular shampoo routine.
