Give roots a lift and strands a fuller-looking finish with Act+Acre Stem Cell Thickening Foam For Volume + Fuller-Looking Hair (120ml), a lightweight styling foam that combines volume with scalp care. This innovative bi-phase formula is infused with clinically backed 2% Apple Stem Cells to help support the scalp’s natural hair growth cycle, while caffeine and an amino acid complex hydrate and energise the scalp. Sarcosine and prebiotic inulin help support scalp balance. For visible volume, hydrolyzed rice protein and corn starch coat each strand, adding body and flexible hold, while jojoba oil helps leave hair feeling soft, not greasy. Designed for early-stage thinning, this multitasking foam helps create thicker-looking, lifted hair while supporting your scalp-care routine.

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
Stem Cell Thickening Foam For Volume + Fuller-Looking Hair is a leave-in 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 shine. The ingredients doing most of that work are Simmondsia Chinensis Seed Oil, Pentylene Glycol and Propanediol. The list runs to 56 ingredients, 14 of which carry a role we recognise for hair.
How it cleanses
It is sulfate-free: the cleansing is done by Decyl Glucoside, milder surfactants that leave more of the hair's own oil behind.
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
It carries a moderate amount of protein — Hydrolyzed Corn Starch, Hydrolyzed Rice Protein and Arginine — enough to firm up damaged lengths without dominating the formula.
On the scalp
For the scalp itself the formula carries Caffeine. On an oily scalp the richer ingredients here can read as greasy at the roots.
Build-up and porosity
Nothing in the list is the kind of ingredient that accumulates on hair.
Where it goes
It is a leave-in: applied after washing and not rinsed out. Shake well to activate the bi-phase formula. Apply 2–4 pumps to damp scalp and roots. Distribute evenly throughout hair using hands or comb. Leave in. Air-dry for soft lift or blow-dry for added fullness and volume.
What it is not for
Nothing in this formula is aimed at volume / lightweight, curl definition, color protection and build-up avoidance — 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.
