Deep Conditioning Hair Mask Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

K18 is the best-performing deep conditioning hair mask brand in July 2026, moving 50,000 units across 1 ASIN for 20.8% of Top 10 volume. Marc Anthony follows with 40,000 units (16.7%), ahead of Elizavecca on 30,000 units (12.5%).

Volume is spread across 10 brands, with the top three holding 50.0% 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 $6.99 to $29.00, 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, 2 ASINs forced its way in: B01I2ZQJSG booked 30K units at $6.99, with ▲ 200.0% MoM change. On the growth side, B0GXXCY7Q5 leads positive momentum with ▲ 566.7% MoM growth on 4K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
