Shimmer Lights is a popular brand of purple shampoo that promises to banish brassy tones and enhance the brightness of blonde, gray, and silver hair. It has become a go-to solution for many people looking to maintain their desired hair color. Have you ever wondered how this magical purple shampoo works? In this article, we will delve into the science behind Shimmer Lights’ number formula and unpack the mysteries of this product.

Before we dive into the nitty-gritty of the science, let’s first understand why purple shampoo is needed in the first place. Hair, especially blonde, gray, and silver hair, tends to develop unwanted brassy or yellow tones over time. This can happen due to a variety of reasons such as exposure to sunlight, chlorine in swimming pools, and the natural oxidation of hair dye. Purple shampoo, like Shimmer Lights, contains violet pigments that help neutralize these brassy tones, resulting in a cooler and brighter hair color.

Now, let’s explore how Shimmer Lights’ number formula works its magic. The “number formula” refers to the concentration of violet pigments in the shampoo. Different formulations of purple shampoos might have different numbers, indicating varying concentrations of violet pigments. Shimmer Lights offers different formulas (often denoted as “Original,” “Silver Lights,” or “Blonde and Silver”) to cater to the specific needs of different hair types.

The violet pigments present in purple shampoo work on the principle of color theory. According to color theory, colors that lie across from each other on the color wheel are complementary, meaning they cancel each other out. In the case of hair, violet is the complementary color of yellow and orange. Therefore, when you apply purple shampoo containing violet pigments, these pigments neutralize the brassy or yellow tones by canceling them out optically, leaving you with a cooler and brighter hair color.

Now that we understand the science behind how Shimmer Lights number formula works, let’s dive into some frequently asked questions about purple shampoo:

1. How often should I use purple shampoo?
– It is recommended to use purple shampoo once or twice a week, depending on your hair’s level of brassiness.

2. Can I leave purple shampoo on my hair for too long?
– Leaving purple shampoo on your hair for too long might result in a slightly purple or gray tint. However, this effect is temporary and can be resolved by washing your hair with regular shampoo.

3. Will purple shampoo work on other hair colors besides blonde, gray, and silver?
– Purple shampoo is specifically formulated for blonde, gray, and silver hair colors, as these are more prone to developing brassy tones. It might not have the same effect on other hair colors.

4. Should I apply purple shampoo on wet or dry hair?
– It is best to apply purple shampoo on wet hair as it helps lather and distribute the product more evenly.

5. Can purple shampoo dry out my hair?

– Yes, purple shampoo can be used on naturally blonde hair to enhance the brightness and combat any developing brassy tones.
