Osmo Ikon Porosity Equaliser is a leave-in treatment which actively rebalances the natural pH of hair to equalise its porosity after a chemical or lightening service. It not only improves hair condition, but also creates a clean canvas for you to work your magic with optimum colour application.

It's formulated with green tea extract and prickly pear oil to help hair stay healthy, reducing static and adding gorgeous shine and condition.

To use, simply bleach or chemically treat hair as normal. Then shampoo, rinse and finally spray Osmo Porosity Equaliser over towel-dried hair. You can also apply it again after colouring to aid restoration of normal pH levels.

Comes in a 250-ml pump bottle.
