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

OCuSOFT is the best-performing lash shampoo brand in July 2026, moving 13,000 units across 2 ASINs for 23.6% of Top 10 volume. STACY LASH follows with 12,000 units (21.8%), ahead of EMEDA on 11,000 units (20.0%).

With 7 brands splitting the Top 10 and 65.5% 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 $9.49 to $18.87, 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: B0D17T3R43 booked 3K units at $8.99, with ▲ 200.0% MoM change. On the growth side, B0B17FGH7Z leads positive momentum with ▲ 100.0% MoM growth on 200 units, with B0CFPYKMGB close behind at ▲ 100.0% MoM on 200 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
