Top 20 Haircare & Styling Best Sellers on TikTok Shop United States — March 2026

TL;DR

Haircare on TikTok Shop US in March is a $42.4M category at +16.3% MoM — same two-headed structure that dominates the chart in subsequent months but on a heavier base. RootLabs' $30 Be Bodywise Hair Density Roll-On Serum holds #1 at $2.16M (+14.5% MoM) — single-SKU revenue 2.3x larger than the #2 spot and the chart's anchor. BASED runs the same five-SKU formation it owns the rack with: #2 the $34 Shower Duo ($919k), #4 the $15 Texture Powder, #5 the $15 Leave-in Conditioner, #7 the $15 Hair Clay, #8 the $30 Texture & Hold Duo — half the top 10. medicube US Store's $34 Rosemary PDRN Scalp-to-Hair serum at #3 ($715k) extends the Korean PDRN molecule from skincare into scalp territory, and Bask and Lather Co takes two seats (#6 the $111 Healthy Hair Bundle holding the premium ceiling, #10 the $16 Scalp Stimulator Hair Growth Oil at the entry price). DS Laboratories' $36 Spectral Men's Hair Density Serum at #9 closes the chart as the only male-targeted hair-density SKU. Signal: this is the structural template that haircare runs on month after month — RootLabs at #1, BASED's 5-SKU formation right behind, and Korean PDRN slipping into scalp care.
