What this product is

Written from the ingredient list. Where it describes how a formula behaves, that is inferred from what the ingredients are and where they sit in the list, not measured.

Overview

Microbiome Cooling Scalp Serum is a serum from Act+Acre, aimed at fine hair, straight hair and wavy hair. On the evidence of its ingredient list, the formula works on moisture, scalp soothing and frizz control. The ingredients doing most of that work are Propanediol, Pentylene Glycol and Niacinamide. The list runs to 24 ingredients, 8 of which carry a role we recognise for hair.

How it feels on hair

The formula reads as lightweight: humectants lead and there is little in the way of heavy oil or silicone, so it should not weigh fine hair down. There are no silicones in the list. The formula leans to moisture rather than protein.

On the scalp

For the scalp itself the formula carries Niacinamide, Panthenol and Menthol.

Build-up and porosity

Nothing in the list is the kind of ingredient that accumulates on hair.

Where it goes

It is a treatment step: after shampooing, left on, then rinsed out. Apply 1-2 pipettes onto clean scalp. Massage into scalp evenly. Leave on and do not rinse. Use it daily post wash or whenever needed.

What it is not for

Nothing in this formula is aimed at protein & strength, volume / lightweight, curl definition and color protection — not a fault, just the shape of what is in the bottle, and the reason one product rarely covers a whole routine. No ingredient here is one we recognise as supporting hair growth. Reducing breakage and growing hair are different things, and this formula's evidence is for the first.
