Best Dr Groot Hair Thickening Serum Brands on Amazon US — Top 3 Brand Sales Concentration (July 2026)
Nutrafol is the best-performing dr groot hair thickening serum brand in July 2026, moving 90,000 units across 1 ASIN for 32.1% of Top 10 volume. WEEM follows with 70,000 units (25.0%), ahead of MARYRUTH'S on 40,000 units (14.3%).
With 9 brands splitting the Top 10 and 71.4% 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 $34.95 to $88.00, which frames the price band a competing listing has to justify.

Trending Dr Groot Hair Thickening 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: B0GQJWBFZ6 booked 10K units at $39.99, with ▲ 11.1% MoM change. On the growth side, B0FPLWRD1Y leads positive momentum with ▲ 700.0% MoM growth on 8K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
