Applying which technique before styling can help create a longer-lasting hairstyle?

1. Hair serum application

2. Heat protectant application

3. Hair spray application

4. Mousse application

The correct answer is: Heat protectant application

Applying a heat protectant before styling is essential for creating a longer-lasting hairstyle. Heat protectants serve a critical function in guarding the hair against damage caused by high temperatures during styling processes, such as blow-drying, curling, or straightening. When applied, these products form a barrier against heat, which can help maintain hair integrity, reduce frizz, and improve overall texture. This protective layer allows for more effective styling without compromising the hair’s health. Healthier hair is generally easier to manage and style, resulting in a longer-lasting finish. Additionally, heat protectants often contain conditioning ingredients that can help the hair remain smooth and shiny, contributing to a more polished appearance that endures through the day. While other techniques like applying hair serum or mousse can contribute to the styling process, they don't focus on the primary goal of protecting hair from heat damage, which is crucial for longevity in hairstyling. Hair sprays are usually utilized for finished looks to hold hairstyles in place but do not play a role in preparing the hair for the heat of styling tools.
