So what is Purple Shampoo and How can it help?

There are quite a few reasons your gray hair can turn yellow or get dull and dingy.

Gray or white hair, which contains little or no pigment, sometimes gets yellow because it picks up pigments from the environment; for example, if you use a yellowish shampoo or conditioner, rather than a clear one, a trace of the color might be deposited on your hair. 

Chlorine and other chemical residues in water, sunlight, and even oils from the scalp can also give gray or white hair a yellowish cast, says David H. Kingsley, PhD, a hair and scalp specialist in New York City. If your water is very chlorinated, install a water filter in your shower; wear a hat when you’re in the sun; and be sure to wash your hair regularly (Monroe, V., 2009).  

So what does purple shampoo have to do with this?

Purple shampoo is primarily designed to counteract unwanted yellow or brassy tones in lightened or gray hair.

The science behind purple shampoo lies in color theory. Purple is opposite yellow on the color wheel, which means they neutralize each other when combined. Gray hair with yellow tones can be toned down or neutralized by using purple shampoo because the purple pigments in the shampoo counteract the yellow tones, restoring a cooler, more neutral shade to the hair.

Purple shampoo does not dye your hair! It acts as a toner, depositing cool violet pigments to counteract the harsh warm yellow or brassy tones peeking through. Regular use of purple shampoo can help keep unwanted brassiness at bay and maintain a consistent cool tone in gray hair.

For those who dye their hair gray or silver, purple shampoo can help extend the time between colorings by neutralizing any yellow tones that may appear as the color fades or as hair grows out.

Depending on the intensity of the yellow tones and the desired result, frequency of use may vary—be sure to read the instructions on the bottle, or ask your hairdresser. It’s typically recommended to use purple shampoo once or twice a week or as needed to maintain the desired tone without overdoing it.
