BC Bonacure pH 4.5 Color Freeze Silver Micellar Shampoo is a violet-pigmented, sulfate-free shampoo formulated for blonde, grey, white, or lightened hair that's developing brassy yellow or warm undertones. Schwarzkopf Professional's pH 4.5 Balancer Technology (lactic acid and calcium hydroxide) resets hair to its optimal pH to help slow color fade, while a violet dye deposits a subtle blue-violet tone with each wash to counteract warmth and add a cool, cendré shimmer. A vegan-keratin blend of soy and wheat amino acids helps fill gaps in the hair's outer layer for added strength and shine.

Massage into wet hair and scalp, leave for one to two minutes to let the toning pigment take effect, then rinse thoroughly and follow with a Color Freeze conditioner. The sulfate- and paraben-free cleansing base makes it gentle enough for regular use, but because it's built specifically for cool-toning, hair without a yellow/warm undertone to correct may end up looking ashier than intended.
