The present invention also relates to a method for dyeing and / or lightening keratinous fibers, such as hair. STATE OF THE ART

[0002] Many people have long sought to change the color of their hair, and in particular to dye it, for example, to cover up their white hair.

[0003] The dyeing product may comprise at least one dye composition and at least one developer composition. For best results, the dye composition and the developer composition may be placed respectively in a multi-compartment package and mixed immediately before use.

[0004] When using hair dye products, especially for home use, consumers often expect ease of application. Foam dye products are becoming very popular due to their ease of application. However, it is difficult to obtain a foam dye with balanced performance in terms of good foaming and stability.

[0005] Therefore, there is a need for stable foam dyeing products having balanced performance in terms of good foamability and stability.

[0006] The formulation of environmentally friendly cosmetic products, which are designed and developed taking environmental issues into account, is becoming a major objective in an effort to meet global challenges.

[0007] It is therefore essential to propose more sustainable compositions, preparation processes and ingredients to address these environmental concerns.

[0008] In this context, it is important to develop new cosmetic compositions with a better carbon footprint, in particular by promoting the use of renewable raw materials and / or materials with a good carbon index. naturalness and / or materials of natural origin, and more particularly, materials of plant origin, while reducing the use of petrochemical compounds. Summary of the invention

[0009] The inventors have discovered that such a need can be satisfied by the cosmetic composition according to the present invention.

[0012] B) a developer composition comprising: i. at least one surfactant.

[0013] According to a second aspect, the present invention proposes a method for dyeing and / or lightening keratinous fibers, comprising:

[0014] - the mixture of the colorant composition and the developer composition mentioned above immediately before use;

[0015] - the application of the resulting mixture to the keratinous fibers; and

[0016] - rinsing the mixture off the keratinous fibers with water, optionally washing the keratin fibers with shampoo before rinsing the keratin fibers with water.

[0017] The inventors discovered that the cosmetic composition produces a high volume of foam and good foam stability when applied to keratinous fibers, preferably hair. Furthermore, the cosmetic composition according to the invention exhibits good stability over time.

[0018] The present invention also relates to the use of the cosmetic composition according to the invention as described above for dyeing and / or lightening, preferably dyeing, keratinous fibers, in particular human keratinous fibers such as hair.
