Which product is commonly used to lock in styling results?

Hair spray is commonly used to lock in styling results due to its formulation designed to provide hold and longevity to hairstyles. When applied to styled hair, hair spray creates a thin, protective layer around the strands, which helps to maintain the desired shape and volume throughout the day. The ingredients in hair spray often include polymers that provide a strong grip without making the hair feel stiff or sticky, allowing for flexibility while still keeping the style intact even in varying conditions such as humidity or wind.

Conditioner, leave-in treatments, and serums, while beneficial for hair health, moisture, and shine, do not provide the same level of hold required to secure a specific style. Conditioners primarily focus on nourishment and detangling, while leave-in treatments are intended to maintain moisture and manageability. Serums often aim to enhance shine or reduce frizz but do not typically provide the structural support needed to lock a style in place. This makes hair spray the product of choice for ensuring that hair looks styled and polished throughout the day.
