Travel Dry Shampoo Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

K18 is the best-performing travel dry shampoo brand in July 2026, moving 30,000 units across 2 ASINs for 25.9% of Top 10 volume. Moroccanoil follows with 28,000 units (24.1%), ahead of MONDAY HAIRCARE on 20,000 units (17.2%).

With 6 brands splitting the Top 10 and 67.2% 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 $6.97 to $36.00, 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. On the growth side, B07J18ZL6P leads positive momentum with ▲ 233.3% MoM growth on 2K units, with B0F67KS3K1 close behind at ▲ 100.0% MoM on 20K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
