Price and performance correlate weakly in grooming — but not randomly. There are categories where the premium product is demonstrably better engineered (shavers, where motor and foil quality decide comfort), and categories where the £12 pharmacy option embarrasses the £60 one (cleansers, almost universally).
The rule we apply: pay up where the product touches you daily and the engineering is hard — shavers, mattresses, styling tools. Save where the chemistry is commoditised — cleansers, basic moisturisers, SPF. The products below are the ones that justify their premium under that test.
Daily-contact engineering: the shaver that decides how every morning starts, and the styler you touch every day for a year per tub.
