Such a result means the product has been applied to very damaged bleached hair. Purple and patchy results from use of Lilac Grey indicate porosity and compromised hair health. Therefore, you should use Precolour Protein Porosity Spray throughout to fill the hair and strengthen. Washing the hair once or twice in a clear, cleansing shampoo will remove any purple or patchy tone. Lilac Grey can then be applied again but do make sure you saturate the hair (throughout) prior to application with Precolour Protein Spray. Doing this will fill any gaps in the hair, equalise porosity and ensure that Lilac Grey deposits throughout the hair evenly.
