Best The Ordinary Hair Serum Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
The Ordinary is the best-performing the ordinary hair serum brand in July 2026, moving 370,000 units across 6 ASINs for 77.1% of Top 10 volume. Mielle Organics follows with 40,000 units (8.3%), ahead of MARYRUTH'S on 30,000 units (6.3%).
With 5 brands splitting the Top 10 and 91.7% 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 $9.94 to $38.95, which frames the price band a competing listing has to justify.

Trending The Ordinary Hair Serum Products — Growth Leaders & New Top 10 Entrants
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: B0DK6W7RPS booked 20K units at $9.99, with ▲ 100.0% MoM change. On the growth side, B0GGQMYLXM leads positive momentum with ▲ 100.0% MoM growth on 6K units, with B07J55YHGD close behind at ▲ 50.0% MoM on 6K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
