HC YELLOW NO. 3

Description

HC Yellow No. 3 is a synthetic hair dye ingredient widely used in semi-permanent and temporary hair coloring products. This water-soluble compound belongs to the azo dye family and is known for its ability to impart vibrant yellow to golden hues to hair. HC Yellow No. 3 is particularly effective in creating warm blonde shades and enhancing golden tones in brown hair.

The molecule's structure allows it to penetrate the hair shaft partially, resulting in color that gradually fades over multiple washes. This characteristic makes it suitable for consumers seeking temporary color changes or those who prefer to experiment with different hair shades frequently. HC Yellow No. 3 is often combined with other dye molecules to create a wide range of color options.

While generally considered safe for use in hair dyes, some individuals may experience skin sensitization or allergic reactions. As with all hair dye ingredients, it is recommended to perform a patch test before full application. HC Yellow No. 3 is approved for use in hair dye formulations by regulatory bodies in many countries, including the European Union and the United States, with specific concentration limitations to ensure consumer safety.
