Kérastase Nutritive Nectar Thermique is a luxurious leave-in heat protectant cream specially formulated for dry and sensitized hair, delivering intense nourishment and thermal protection up to 230°C while its rich, creamy texture melts into strands to seal in moisture, eliminate frizz, and create a silky smooth finish that lasts all day. Enriched with Irisome Complex and nourishing actives, this 150ml primer works as a pre-styling treatment that shields hair from blow-drying, flat ironing, and curling tools, leaving every strand visibly softer, shinier, and more manageable with each use.
