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

Native is the best-performing giovanni shampoo brand in July 2026, moving 30,000 units across 1 ASIN for 34.5% of Top 10 volume. OUAI follows with 14,000 units (16.1%), ahead of Olaplex on 10,000 units (11.5%).

With 9 brands splitting the Top 10 and 62.1% 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 $19.78 to $68.00, 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, B0BD2SKVTJ leads positive momentum with ▲ 66.7% MoM growth on 5K units, with B000YDYXBK close behind at ▲ 50.0% MoM on 300 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
