Leave-in scalp serum

Fuller-looking hair starts at the scalp

A lightweight, water-based serum you massage into the scalp once a day and leave in. The Ordinary formulated it with several peptide and plant-extract complexes and high-solubility caffeine to improve the look of hair thickness, fullness and density.

What is in the formula

Several complexes work together: pea sprout extract, European larch with green tea and zinc, apigenin and oleanolic acid with biotinoyl tripeptide-1, acetyl tetrapeptide-3 with red clover, and Chinese skullcap with soy and wheat germ, plus high-solubility caffeine.

Density at the root

Used daily, it helps visibly improve hair density at the root for more volume, and helps combat the look of thinning by making strands look denser. Massaged in with the fingers, it can help improve microcirculation to the scalp.

Light enough for every day

The water-based formula absorbs easily with no greasy residue. It is silicone-free, alcohol-free, vegan and gluten-free, with a pH of 4.80 to 5.80, and The Ordinary says it suits all hair types.

How to use

A few drops on the scalp, once a day

Massage a few drops thoroughly into a clean, dry scalp once daily, ideally at bedtime. It is a leave-in treatment, so do not wash your hair or scalp after applying it. Use it only as directed, on unbroken skin.

  • Try it on your forearm first.
  • If irritation occurs, rinse and stop.
  • Keep direct acids for another time.
