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.

Hair oils
Price barely matters here: a 10% discount typically buys 3–6% of rank, an increase costs 2–5%.

Face moisturisers
A big category that reacts mildly in both directions — and raising the price costs less rank than an equal discount earns.
