His deductive reasoning, keen observation skills, and ability to solve complex cases make him a formidable detective. However, there are many other fictional detectives who are also considered highly intelligent, such as Sherlock Holmes and Hercule Poirot. Ultimately, the title of "smartest detective" is subjective and can vary depending on individual opinions and the specific criteria used to measure intelligence. **

The order of shampoo, conditioner, and treatment can vary depending on individual hair care needs. However, a common order is to first shampoo the hair to cleanse it, then apply conditioner to moisturize and detangle, and finally use a treatment product for specific hair concerns such as deep conditioning or repairing damage. It's important to consider your hair type and specific needs when determining the best order for your hair care routine. **
