King Brown Thickening Serum 120ml

A leave-in scalp serum rather than a styling product. It goes onto the scalp, not through the hair, twice a day, and stays there — which makes it the anchor of the King Brown thickening routine rather than an add-on to it. 120ml in a pump bottle, so the dose is easy to keep consistent.

What's in it

• Procapil® — a complex of oleanolic acid, biotin and apigenin.
• Trichogen™ — panax ginseng root extract with amino acids and vitamins including biotin and niacinamide.
• Arginine — an amino acid, included alongside the two complexes.

How to use it

Two to three pumps directly onto the areas of concern, morning and night. Massage it thoroughly into the scalp so it absorbs properly rather than sitting on the surface, and leave it in — it isn't rinsed out. Consistency matters far more here than quantity.

Worth knowing

This is a topical cosmetic for external use only. It is not an oral or prescription treatment, and it isn't a substitute for one. If thinning is a real concern for you, it's worth speaking to a doctor as well.
