Best Hair Serum Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Mielle Organics is the best-performing hair serum brand in July 2026, moving 40,000 units across 1 ASIN for 22.2% of Top 10 volume. COLOR WOW follows with 30,000 units (16.7%), ahead of The Ordinary on 30,000 units (16.7%).
Volume is spread across 9 brands, with the top three holding 55.6% 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 $9.94 to $30.00, which frames the price band a competing listing has to justify.

Trending 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, 2 ASINs forced its way in: B09P8FYJJL booked 10K units at $10.49, with ▲ 11.1% MoM change. On the growth side, B07J55YHGD leads positive momentum with ▲ 50.0% MoM growth 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
