Product Insights
The durable 7-oil black-blue hair dye 909 is a permanent hair coloring product that delivers a deep black-blue shade while incorporating a blend of seven conditioning oils. Its formulation mixes synthetic oxidative colorants, which provide long-lasting pigment, with nourishing oils such as argan, jojoba and coconut that aim to restore moisture and reduce post-color brittleness. Nevertheless, the inclusion of traditional hair-color chemicals like ammonia and para-phenylenediamine can cause scalp irritation or allergic reactions for sensitive users, and the plastic-cardboard packaging offers limited environmental benefit.
Comparative Analysis
Positioned as a long-lasting black-blue hair dye enriched with seven conditioning oils, it appeals to consumers seeking vivid, durable colour while keeping hair softness, setting it apart from standard dyes that lack added moisturizing agents.
