Hair Treatment Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Nizoral is the best-performing hair treatment brand in July 2026, moving 100,000 units across 1 ASIN for 21.3% of Top 10 volume. Nutrafol follows with 90,000 units (19.1%), ahead of K18 on 50,000 units (10.6%).

Volume is spread across 10 brands, with the top three holding 51.1% 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 $16.88 to $88.00, 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, 3 ASINs forced its way in: B01I2ZQJSG booked 30K units at $6.98, with ▲ 200.0% 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
