A non-oxidising colour (direct acting true semi-permanent and temporary colours) can be applied directly after the first shampoo. Oxidising colours (tints, bleach, quasi-permanents) can be used either 2 days before the service or 2 days afterwards. It is usually best to highlight prior and full head colour after the treatment.
