Blue Shampoo vs Purple Shampoo

Blue and purple shampoos help maintain vibrant hair color. They counteract unwanted yellow or brassy tones in blonde, gray, and white hair. This article explains the difference between these two specialized shampoos and helps you choose the right one.

Understanding the Color Wheel

The color wheel helps us understand how color correction works. Colors opposite each other on the wheel neutralize one another. Yellow sits opposite purple, and orange sits opposite blue. This principle guides how blue and purple shampoos work.

Purple shampoo neutralizes yellow tones, primarily affecting light blonde, silver, platinum, and gray hair colors. Yellow is often the unwanted hue that appears in these colors as they lighten or fade. Purple shampoo helps these shades stay brighter and truer to their intended color, preventing them from looking dull or brassy. It can also refresh highlighted or bleached hair.

Blue shampoo, on the other hand, addresses orange tones that often appear in brunette hair after lightening or dyeing. Blue pigments counteract orange, keeping the hair color rich and vibrant. Common use cases include preserving richer browns and counteracting orange hues that might develop in dark blonde hair.

Target Hair Colors for Blue Shampoo

Blue shampoo primarily benefits those with light brown to medium brown hair. Individuals who lighten their naturally darker hair or dye it shades of brown often use blue shampoo. The shampoo helps manage orange tones, a common side effect of lightening dark hair. Lightened brown hair usually develops unwanted warmth over time, and blue shampoo corrects this color shift. Its consistent use maintains the desired brown shade and avoids brassiness.

Certain shades of dark blonde hair can benefit from blue shampoo as well. It targets orange tones that sometimes appear in these hair colors. For these cases, blue shampoo offers a gentler approach compared to purple shampoo, which might over-correct and add unwanted purple hues.

Target Hair Colors for Purple Shampoo

Purple shampoo works best on light hair colors. It benefits blondes, particularly those with very light shades like platinum and silver. The violet pigments counteract yellowing, a common issue with these shades. Gray and white hair also often benefit from purple shampoo. These hair colors can develop yellow tints from environmental factors like minerals in water or product buildup. Purple shampoo neutralizes these yellow tones and maintains a clear, bright appearance. Those with highlighted or bleached hair can use purple shampoo to refresh their color and reduce brassiness.

While usually associated with lighter shades, purple shampoo can sometimes benefit those with light to medium brown hair. In these cases, it works to brighten highlights and add dimension. However, use it sparingly, as overuse on darker hair may lead to a purplish tint.

How to Use Blue and Purple Shampoos

Both blue and purple shampoos require specific application methods for best results. First, wet your hair thoroughly. Then, apply the shampoo evenly throughout, ensuring complete coverage of the areas you want to treat. Lather the shampoo and allow it to sit for the recommended time, typically between 2-5 minutes depending on the product and your hair’s needs. The product packaging usually provides detailed instructions regarding application time.

Overusing either shampoo may cause unwanted discoloration. Start with shorter durations and gradually increase if necessary. Monitor your hair’s response to the shampoo. If you see excessive blue or purple hues, reduce the application time or frequency. Always rinse your hair thoroughly after using a color-correcting shampoo. Follow with a moisturizing conditioner to replenish hydration and maintain hair health.

Choosing the Right Shampoo

Choosing between blue and purple shampoo depends on your hair color and the specific tone you want to correct. If your light to medium brown hair has unwanted orange tones, select a blue shampoo. If you have blonde, gray, silver, or highlighted hair with yellow tones, choose purple shampoo. Use a color wheel as a visual guide. Identify the unwanted color in your hair and choose the shampoo with the opposing color.

Consult a hair professional if you are unsure. They can help determine the right shampoo for your hair type and color. Experimentation and observation are key. Pay attention to how your hair responds to each shampoo. Adjust the frequency and duration of application as needed to achieve optimal results and maintain your desired hair color.
