Is Dexe Black Hair Shampoo natural?

Could you please elaborate on whether the Dexe Black Hair Shampoo is formulated with natural ingredients? I'm particularly interested in understanding its content, such as whether it contains any synthetic chemicals or preservatives. Additionally, I'm wondering if the shampoo is cruelty-free and if its production process adheres to sustainable practices. Finally, it would be helpful to know if there are any user reviews or testimonials that discuss the shampoo's effectiveness and naturalness. Thank you for your assistance in clarifying these points.
