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

2% Stem Cell Scalp Serum For Thicker-Looking Hair 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, frizz control and protein & strength. The ingredients doing most of that work are Glycerin, Butylene Glycol and Aloe Barbadensis Leaf Juice. The list runs to 24 ingredients, 9 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.

Protein

There is a small amount of protein in the list: Collagen.

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 one or two pipettes directly to clean, damp or dry hair along the hairline and parting. Massage into scalp evenly. Leave on and do not rinse. Use daily for best results.

What it is not for

Nothing in this formula is aimed at scalp soothing, oil control, volume / lightweight and curl definition — 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.

Working for it

  • No sulfate detergents
