Coloured hair often becomes porous, especially after repeated dyeing, and is therefore particularly susceptible to damage. In many cases, the porosity also causes it to lose colour pigments much more quickly and fade. Schwarzkopf Professional pH 4.5 Colour Freeze Conditioner was developed to prevent this effect. This conditioner cleans and cares for coloured and porous hair intensively and very gently at the same time. It detangles the hair, improves combability and manageability and ensures that the hair and scalp regain their natural pH value. Schwarzkopf Professional pH 4.5 Color Freeze Conditioner is free from artificial colourants and contains no silicones or parabens. The conditioner is also vegan and therefore free from animal ingredients. It smoothes the hair surface and ensures a naturally silky shine.Improves the colour retention With Schwarzkopf Professional pH 4.5 Color Freeze Conditioner, you can revive dull hair colours in no time at all and improve the colour retention of your colouring by up to 90 percent for up to 30 washes. The optimum pH value of 4.5 ensures that the hair and scalp are rebalanced and thus better protected against external influences. Apply to damp hair after shampooing, leave on for 2 minutes and then rinse out.
