Ranked Top 5 (UK Availability)
Quick Notes for UK Shoppers
- Technique tip (repeated across UK reviews): Focus shampoo on the scalp, massage well, and apply conditioner only to mid-lengths and ends.
- Use a stronger clarifying option (OUAI or L’Oréal Professionnel) 1–2 times a week and a milder daily wash the rest of the time.
- Budget standout: Monday Haircare is hard to beat for performance-to-price.
- Premium/luxury feel: Kérastase or OUAI.
- If you also have dandruff, consider Vichy Dercos (normal-to-oily version) as a strong alternative.
Prices fluctuate with sales (especially on Lookfantastic and Amazon), so check current offers. All of these are currently stocked across major UK retailers. If you have specific preferences (e.g., sulphate-free only, fine hair, colour-treated, or a tight budget), I can refine the list further.
