Kerastase Miracle Reshapable Heat Blow Dry Lotion - with long wear hold. Couture Styling L'incroyable Blowdry from the Kérastase is a magical cream for all hair types that enables flexible heat styling. Repeated makeovers are no problem with heat-activated micro waxes. At the same time, the hair is protected from heat and is optimally malleable. The hairdo looks lively and mobile. The exceptional micro-waxes in L'Incoyable Blowdry Crème melt when heated and wrap themselves around the hair fiber so that the hair can be styled. By applying heat again, the hair can be shaped again without having to apply the cream again.
