Why does porosity matter for colour results?

Uneven porosity is one of the most common reasons colour results are inconsistent — high porosity areas absorb more pigment and can go darker or more intense, while low porosity areas resist colour uptake. By equalising porosity levels before colour application, the Osmo IKON Porosity Equaliser gives the colour a more even surface to work with, helping to achieve consistent, predictable results from roots to ends. The pH restoration step is equally important — hair that has been processed or chemically treated often has a disrupted pH, and rebalancing this before colour application helps the colour penetrate more effectively and last longer. It's an essential pre-colour step for anyone working with colour services on damaged or porous hair.

How do you use it?

Apply evenly to clean, towel-dried hair before colour application, leave for a few minutes to allow the formula to work, then apply colour as normal. Find the full Osmo professional range and complete selection of colour service products on site.
