Biolage Thermal Active Setting Spray – Heat Protection & Hold 250ml Hair type_Medium Leave in for 5-10 minutesHeat protection that also sets the style. The Thermal Active Setting Spray does two jobs in the step where most people only do one: it shields the hair from the heat of a dryer, iron or wand, and it sets the shape you're creating as it dries. Sprayed on damp hair before blow drying it gives the style something to hold onto, so the result lasts longer than the styling session did and the fibre takes less damage getting there. 250ml.
