Purple shampoo is a colored shampoo specifically produced for people with blonde to white or gray hair for toning or covering yellowing hair that can be caused by heat damage, mineral buildup, sun damage, and chlorine damage. This shampoo contains a dye that is known as Violet #2. Purple is opposite yellow on the color wheel, so it helps cover or hide yellow tones.

Water or chemicals like bleach and chlorine can damage light hair and turn its colors brassy and yellowed. Whether you are a natural blonde, have dyed your hair a lighter color, or have recently gone gray, purple shampoo can restore more natural and glossy color to your hair.

Be patient when using purple shampoo. Although you may see some results at first, it can take several treatments to see a substantial change in your hair color. Essentially, the purple shampoo will deposit a small amount of violet pigment into your yellowy hair. Enjoy your cool-toned blonde!
