Biolage Smooth Proof Serum is a lightweight treatment that hydrates dry strands and tames frizz, helping hair become more manageable and radiant with natural-looking shine.
Ideal for unruly, frizz-prone hair, this serum softens and smooths without heaviness, making everyday styling easier and delivering a sleek, polished finish from morning to night.
How to use: After washing, apply 1–2 pumps to palm and distribute through damp hair, focusing on mid-lengths and ends. Style as usual. For targeted control, smooth a small amount onto dry sections to tame flyaways without weighing hair down.
