Viviscal Hair Growth Supplement For Women Market Report: Sales Volume, Market Share, Leading Brands & Market Trends

Nutrafol is the best-performing viviscal hair growth supplement for women brand in July 2026, moving 140,000 units across 3 ASINs for 29.8% of Top 10 volume. Vital Proteins follows with 120,000 units (25.5%), ahead of WEEM on 70,000 units (14.9%).

With 7 brands splitting the Top 10 and 70.2% 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 $22.32 to $88.00, 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, B09HTHWQ45 leads positive momentum with ▲ 50.0% MoM growth on 3K units, with B0DVBKH321 close behind at ▲ 25.0% MoM on 10K 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already changed hands — an incumbent gave up its place to make room, so any competitive set drawn up a month ago is now out of date.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.
