About this product

A lightweight scalp serum for thinning hair, built around 5% Capixyl, caffeine, biotin, rosemary and saw palmetto.

Re:GRO Scalp Serum goes where hair actually starts: the scalp. It is a non-sticky, fast-absorbing serum with a cool, fresh finish that will not weigh hair down or leave it greasy, so you can use it on clean or day-two hair and style as usual.

What's inside

  • 5% Capixyl: a peptide and red clover complex studied for supporting fuller-looking, denser hair
  • Caffeine: wakes up the scalp and supports circulation to the follicles
  • Biotin: helps reduce brittleness and breakage
  • Rosemary, castor and pumpkin seed oils: long-used botanicals that nourish the scalp
  • Saw palmetto: a traditional botanical for scalp and hair support

Who this is for

  • Early thinning, a widening part or a receding hairline
  • Shedding after pregnancy, stress or illness
  • Weak, breakage-prone strands, including color-treated, chemically treated or extended hair
  • Tension from tight hairstyles
  • Dry or oily scalps

How to use

Part hair into sections and apply the serum directly to the scalp, focusing on thinning areas. Massage in with your fingertips for a minute and leave in; do not rinse. Use at least four times a week. Give it a full 12 weeks of steady use (about three bottles) to judge results. For best results, pair it with the Re:GRO Anti-Thinning Shampoo and Conditioner. If you are pregnant or breastfeeding, check with your doctor first.
