Biotop 101 Create Top Coat Spray is a humidity-resistant pre-styling spray that creates a smooth, controlled base and helps a style stay frizz-free for longer.
Polysilicone-29 forms an invisible film around the hair fibre that helps block humidity, which is what keeps frizz and flyaways down. The spray is light and leaves no visible residue, so the hair keeps its softness and movement.
Spray evenly on damp or dry hair before styling, focusing on frizz-prone areas and the mid-lengths and ends, then blow-dry or style. Biotop lists it as vegan.
