Is this gel-cream colorant suitable for sensitive or chemically treated hair?

The formula is ammonia-free and contains conditioning ingredients like glycerin, which can be gentle on hair, but it also includes strong dyes such as P-Phenylenediamine and Resorcinol, as well as fragrance allergens, so users with sensitive scalps or previously treated hair should perform a patch test first.

What role does P-Phenylenediamine play in the gel-cream colorant and why is it used?

P-Phenylenediamine is the primary oxidative dye molecule that reacts with hydrogen peroxide to develop permanent color; it provides deep, lasting shades, especially in dark brown tones, but it is a known sensitizer and can cause allergic reactions in some individuals.

How should the product be applied and are there any controversial ingredients to be aware of?

Mix the coloring cream with the developer as instructed, apply to dry hair, leave for the recommended time (typically 30-45 minutes), then rinse and follow with the included shampoo; be aware that the formula contains controversial ingredients such as P-Phenylenediamine, Resorcinol, Methylchloroisothiazolinone, Methylisothiazolinone, and fragrance components like Limonene and Linalool, which may cause irritation or allergies.

Product Insights

The Gel Creme Colorant No.30 is an ammonia-free, dark-brown hair-color gel-cream sold in 50 ml cartons and plastic packaging, available at U Express in France. It combines a coloring cream, a peroxide developer and a gentle shampoo, with conditioning agents such as glycerin and oleic acid for smoothness. However, the formula also includes strong oxidative dyes (P-Phenylenediamine, Resorcinol), surfactants (Sodium Laureth Sulfate) and a preservative mix (Methylchloroisothiazolinone, Methylisothiazolinone), as well as fragrance allergens (Limonene, Linalool, Citronellol), which may irritate sensitive scalps.

Comparative Analysis

Compared with standard permanent hair dyes, this product differentiates itself by offering an ammonia-free three-step kit (color cream, developer, shampoo) tailored for deep brown tones, appealing to DIY users seeking salon-level results while competing with conventional dyes that often rely on ammonia for pigment lift.
