How to Use:
Apply to wet hair and work into a rich lather. Leave on for 1–3 minutes, then rinse thoroughly. For more intense toning, leave on for up to 5 minutes. Use 1–2 times per week or as needed, depending on your desired level of toning. Follow with Nº.5P Blonde Enhancer™ Toning Conditioner for maximum toning and conditioning benefits. 

Pro Tip: Purple shampoo is best used as a toning treatment—not necessarily your everyday shampoo. Start with a shorter processing time and increase gradually if you want more neutralization.

Best For: Blonde, highlighted, lightened, and gray hair that looks dull, yellow, or brassy and needs a brighter, cooler-toned finish.
