What it actually does.
Where most leave-in serums coat the strand and call it a day, Finish Serum repairs from inside. The KIB peptide migrates into damaged cuticle gaps; squalane mimics your hair's natural lipids; niacinamide reinforces protein bonds. The result is the polished finish you want — without the silicone build-up that gradually suffocates roots.
It works under heat tools, over braids, on second-day hair. A little goes a long way: 2-4 pumps for shoulder-length, 5-6 for longer.
Four steps,
once you've got the rhythm.
Warm in palms
Pump 2-4 drops into clean palms. Rub them together for 5 seconds — body heat activates the squalane.
Apply mid-shaft down
Smooth through the lower 2/3 of your hair. Avoid roots — Finish Serum is for the ends, not the scalp.
Comb through
Wide-tooth comb to evenly distribute. The serum is invisible when properly absorbed.
Style and forget
Heat-protective up to 230 °C / 450 °F. Use on dry days as touch-up to tame frizz.
Five actives,
nothing extra.
Full INCI on the label, no hidden fragrance complex, no greenwashed marketing. Here's exactly what's in the bottle and why.
KIB Peptide™ complex
Migrates into cuticle gaps and reinforces from within. Same active as Booster Oil — different delivery system.
Squalane (olive-derived)
Mimics natural sebum. Restores shine without weight. Non-comedogenic on scalp areas you accidentally touch.
Niacinamide
Reinforces protein bonds within the shaft. Improves tensile strength under mechanical stress (brushing, styling).
Argan oil
Rich in tocopherols and oleic acid. Smooths the cuticle, adds the polished finish.
Vitamin E (mixed tocopherols)
Protects squalane from oxidation. Extends shelf life without synthetic preservatives.
Real people, real timelines.
My split ends are quieter
"I have very long, very bleached hair. After 6 weeks of using this 3-4 times a week, my ends look way less crispy. I trimmed an inch and the new look held — usually I'd be wrecked again in a week."
Replaced 2 products
"I was using one serum for shine and another for heat protect. This does both. My bathroom shelf is now actually pretty."
Subtle, takes patience
"I expected a 'wow' moment — there wasn't one. Just consistent gloss week after week. After 6 weeks I realised my hair looks better in photos. Subtle but real."
