Should you use blue shampoo on gray hair?

White Scribbled Underline

Nope. Skip blue and green shampoo on gray hair.

Why? It's simple color theory.

Color Theory 101

When we look at the color wheel, we know that yellow + red make orange and red + blue make purple, etc.

Yellow + Blue = GREEN

When someone with yellow-y gray hair uses a blue shampoo, guess what color you are going to get? That’s right. GREEN! Blue shampoo is not designed to be used on gray hair; its function is to neutralize orange tones in brown hair.

Purple Shampoo Neutralizes Brassy Tones

y Now

Purple shampoo is the best toner to use when it comes to gray hair because it neutralizes brassiness caused by heat styling, medications, product buildup, sun, salt, chlorine and environmental pollutants.

Purple shampoo is designed for lighter hair.

Purple shampoo will only work for gray hair that is a level 8 or higher (which in this case, means lighter), so if you have darker gray hair or dark hair with just a few grays, purple shampoo may not work for you.
