Shampoo For Oily Hair Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Nizoral is the best-performing shampoo for oily hair brand in July 2026, moving 150,000 units across 2 ASINs for 42.9% of Top 10 volume. TRESemmé follows with 40,000 units (11.4%), ahead of Neutrogena on 30,000 units (8.6%).

With 9 brands splitting the Top 10 and 62.9% of volume sitting with three of them, this is a concentrated shelf — the leaders hold multiple listings or one very high-velocity ASIN, so a new entrant competes against established review moats rather than an open field. Average selling prices among the leaders run from $7.79 to $23.17, 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, 3 ASINs forced its way in: B076JK8PXX booked 40K units at $10.74, with ▲ 100.0% MoM change.

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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
