Kerastase Conditioner Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

K18 is the best-performing kerastase conditioner brand in July 2026, moving 50,000 units across 1 ASIN for 33.6% of Top 10 volume. Pureology follows with 20,000 units (13.4%), ahead of Moroccanoil on 10,000 units (6.7%).

Volume is spread across 10 brands, with the top three holding 53.7% between them. No single label controls the shelf, which usually leaves room for a well-differentiated listing to take share without outspending an incumbent. Average selling prices among the leaders run from $29.00 to $38.00, which frames the price band a competing listing has to justify.

Based on July 2026 data, this shortlist surfaces the two kinds of ASIN worth keeping an eye on — the ones that just broke into the Top 10, and the ones growing fastest month over month. Specifically, one ASIN forced its way in: B0G3D8F18H booked 10K units at $33.00, with ▲ 0.0% MoM change. On the growth side, B0DWCGX8L2 leads positive momentum with ▲ 100.0% MoM growth on 2K units, with B09HR5KSR8 close behind at ▲ 25.0% MoM on 50K units.

The two signals carry different weight. A fresh entrant means share has already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date. A steep growth rate works as the earlier warning: it marks demand that is still compounding, usually a month or two before the ranking catches up to it.
