Beauty & Personal Care · Q3 2026

12 of 13 published

Category	What I found	Cuts	Increases	Date
Hand soaps	The weak end of the series: price effects exist in both directions, at roughly a fifth of what the strong categories show, in a market that answers in weeks.	0.19[0.03–0.47]	0.24[0.08–0.42]	22 Sept 2026
Beard oils	A small, slow niche: cuts work modestly, increases show no demonstrable effect at all, and the median competitor answer takes five days.	0.50[0.22–0.86]	0.21[−0.22–0.57]	15 Sept 2026
Fragrances (women)	The strongest price response in the series to date: a full staircase in both directions, on the biggest shelf measured so far.	1.11[0.97–1.25]	0.93[0.77–1.10]	8 Sept 2026
Fragrances (men)	The first category with a demonstrable segment order: the expensive shelf dances to price, the cheap shelf barely moves — in both directions.	1.00[0.82–1.20]	0.78[0.61–0.97]	1 Sept 2026
Conditioner	A symmetric category with one demonstrable gradient underneath: the more expensive the bottle, the harder a price increase hits.	0.54[0.42–0.66]	0.50[0.35–0.66]	25 Aug 2026
Shampoo	Shampoo reacts weakly to price overall. Premium responds clearly, the mid segment barely at all, and budget price increases showed no measurable rank cost.	0.40[0.28–0.55]	0.36[0.24–0.48]	17 Aug 2026
Hair oils	Price barely matters here: a 10% discount typically buys 3–6% of rank, an increase costs 2–5%.	0.47[0.34–0.61]	0.35[0.21–0.50]	17 Aug 2026
Face sunscreen	Both directions move rank by less than the price change itself; increases cost roughly half of what cuts gain.	0.69[0.51–0.95]	0.55[0.41–0.69]	17 Aug 2026
Face moisturisers	A big category that reacts mildly in both directions — and raising the price costs less rank than an equal discount earns.	0.84[0.64–1.05]	0.80[0.64–0.97]	17 Aug 2026
Face cleansers	Price works the same at €8 as at €40 — no segment stands out in this category.	0.62[0.50–0.74]	0.56[0.43–0.68]	17 Aug 2026
Eye creams	The most expensive skincare category is also where discounts work best: cuts move rank roughly one for one.	1.03[0.88–1.21]	0.80[0.65–0.95]	17 Aug 2026
Face serums	The more expensive the serum, the better discounts work: premium responds clearly, budget barely.	0.90[0.72–1.09]	0.88[0.72–1.04]	17 Aug 2026
