Shampoo is the step most people over-think and under-match. What it actually does is remove oil, product and dirt from the scalp — everything else on the bottle is secondary. The main variable is the surfactant system: sulphates such as SLS clean thoroughly and lather well, while sulphate-free formulas clean more gently and suit colour-treated or curly hair, at the cost of a less satisfying lather. The picks below are shampoos available on Amazon UK ranked on customer rating weighted against review volume. This is a category where price correlates weakly with results, and several of the best-rated options sit under £10.

Shampoo is a scalp product. Choose it for how oily or dry your scalp is, and use conditioner and masks to look after the lengths — those two ends of the same hair often need opposite things.
Gentler cleansing helps colour last and suits curls, but on a very oily scalp or with heavy silicone products it may not clean thoroughly enough, leaving hair limp after a day.
They strip build-up from styling products and hard water, which is useful roughly monthly. Used as an everyday shampoo they will leave most hair dry.
Look for zinc pyrithione, ketoconazole or selenium sulphide. A shampoo marketed for flaking without one of those is a moisturising shampoo with a marketing angle.
This category ranges from 200ml to over a litre. The cheapest bottle is frequently the most expensive per wash, so it is worth dividing before deciding.
