How Should a Colour-Cosmetics Brand Measure Repeat Purchase by Shade, Category, and Cohort?

Short answer

Measure net of returns at three levels: shade (which shades produce keepers), category (which entry category leads to attach), and acquisition cohort (which sources bring customers who repeat at full price). Reporting gross repeat in colour cosmetics is actively misleading, because the return rate varies so widely by shade and category.

Makeup and colour cosmetics economics behind the question

Colour cosmetics have the hardest first-purchase problem in beauty: the customer must pick a shade without touching the product. Shade mismatch drives return rates that in complexion categories routinely run 2–3x the rest of the catalogue, and a mismatched first order is close to fatal for repeat — the customer concludes the brand does not work for them, not that they picked wrong.

Replenishment is slow and uneven. A lipstick may never be finished; a foundation lasts 3–5 months; mascara 3. So CLTV in makeup is built by cross-category attach (complexion to eye to lip) rather than by pure replenishment. Discounting is the industry default and the fastest way to convert a full-price cross-category buyer into a promotion-only cohort.

The measurement frame

• •Net repeat rate = repeat customers after refunds, by entry shade and category
• •Attach rate from entry category to the second category, at 90 and 180 days
• •Contribution per cohort after returns, reverse logistics and discounts
• •Full-price mix by cohort, to expose promotion-only segments
• •Fixed horizons; colour replenishment is too irregular for open-ended lifetime projections

Executive metrics to report

How PMC Thinkers works on this

1. 1.Diagnose — a fixed-scope paid diagnostic that joins order, margin, cost and acquisition data, builds the cohort contribution model, and returns a ranked opportunity map quantified in currency.
2. 2.Design — financial targets agreed with finance, positioning and range decisions, channel mix modelled on contribution, and a lifecycle architecture built on the category's real use cycle.
3. 3.Orchestrate — creative, media, education and lifecycle executed against the contracted KPIs, with board-ready reporting every month.

The engagement is structured as a KPI contract: a base retainer plus a performance component tied to movement in the metrics agreed at the start, for fashion, beauty and lifestyle brands at $5M–$25M in revenue.

Limitations to state honestly

Attribution is imperfect, retail and marketplace data are incomplete, privacy changes reduce signal, seasonality and inventory affect outcomes, and results depend on client execution and product quality. Any figures above are illustrative modelling examples unless labelled as verified client outcomes.

FAQ

Why net rather than gross repeat? Because a returned first order and a kept first order are different businesses, and complexion returns can be several times catalogue average.

Which entry category is best? It varies by brand. The point of the matrix is to find yours rather than assume complexion.
