How do you use Dexe shampoo?

Could you kindly elaborate on the steps involved in utilizing the Dexe shampoo? I'm quite curious about its application process. Would it be similar to the regular shampoo I'm accustomed to? Or does it have any specific instructions that I should be aware of? I'm also interested in knowing if there are any pre-shampooing rituals or post-shampooing care tips that are recommended for maximizing its effectiveness. Could you please provide a detailed description of how I should use this shampoo to ensure the best results?
