How to use it
Massage through wet hair, then rinse, and follow with the Bust Your Brass conditioner. Avoid contact with eyes.
How often depends on your blonde. For natural blondes in summer, platinum, highlights, balayage and color-treated hair, use it every other wash; platinum hair showing brassiness can use it every wash until the tone you want returns. Gray hair can use it every wash, or alternate washes with The Kure line, such as the Kure strength repair wash.
If your hair turns too cool or nears violet, cut back for a week or two. If brassiness creeps back, add one use per week.
