Insider information from our blonde experts:

• Monitor the bleach as it works on the hair and finish the process when a clear blonde shade has been achieved
• Remember that the scalp’s heat plays a role in the lightening process. Roots of the hair lighten faster than lengths and ends
• Protect the scalp: never use peroxide concentrations exceeding 6% to lighten roots
• We recommend pastel-coloration with Koleston Perfect or other Wella Professionals colour products
