Before giving a chemical wave, the hair should be?

Blow-dried
Analysed and shampooed
Straightened
Moisturized

The correct answer is: Analysed and shampooed

Before giving a chemical wave, it is important to first analyze and shampoo the hair. This is because when applying a chemical wave, the hair should be free of any product build-up or residue which may impact the effectiveness of the chemical solution. While blow-drying, straightening or moisturizing the hair may be part of some people's haircare routine, they are not necessary steps before giving a chemical wave and may potentially affect the results. Therefore, it is important to clean and prepare the hair by analyzing and shampooing it before giving a chemical wave.
