HC YELLOW NO. 10

Description

HC Yellow No. 10 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 imparting vibrant yellow to golden hues to hair. Unlike permanent dyes, HC Yellow No. 10 does not penetrate the hair shaft deeply, instead coating the hair's surface and gradually washing out over time.

The molecule's structure allows it to adhere to the hair cuticle without causing significant damage, making it a popular choice for those seeking temporary color changes or highlights. HC Yellow No. 10 is often combined with other dye molecules to create a range of warm tones, from honey blonde to rich auburn.

While generally considered safe for use in hair products, some individuals may experience allergic reactions. It's advisable to perform a patch test before application. The ingredient is regulated by cosmetic authorities in various countries, with specific concentration limits set to ensure consumer safety. HC Yellow No. 10's efficacy can be influenced by factors such as hair porosity, previous chemical treatments, and natural hair color.
