DISPERSE BLUE 377

Description

Disperse Blue 377 is a synthetic dye commonly used in haircare products, particularly in temporary and semi-permanent hair colorants. This azine-based compound is known for its vibrant blue hue and its ability to adhere to hair fibers without permanent alteration of the hair structure. The dye molecule is designed to penetrate the hair cuticle and deposit color within the cortex, resulting in a temporary change in hair color.

The efficacy of Disperse Blue 377 is attributed to its low molecular weight, which allows for better penetration into the hair shaft. It is often combined with other dyes to create various shades and tones in hair coloring products. This dye is particularly effective on pre-lightened or naturally light hair, providing intense blue tones that can last through several washes.

While Disperse Blue 377 offers vivid color results, it's important to note that it may cause skin or scalp irritation in some individuals. As with all hair dyes, patch testing is recommended before full application. The longevity of the color can vary depending on hair porosity, frequency of washing, and exposure to environmental factors such as sunlight and chlorine.
