Spray is a popular styling product that can be used to add texture, hold, and shine to hair. The amount of time that spray should stay in the hair depends on a number of factors, such as the type of spray used, the desired look, and the hair type.
For everyday looks, using a light-hold spray is often enough to keep hair in place. A light-hold spray should be applied evenly throughout the hair and allowed to dry naturally. Depending on the hair type, light-hold spray may need to be reapplied after a few hours to maintain the desired style.
For more formal looks, a medium-hold or strong-hold spray may be necessary. Medium-hold spray should be applied in layers, usually focusing on the areas that need the most hold. Once the desired look has been created, the spray should be set with a blow-dryer or curling iron. Medium-hold spray should stay in the hair for 12-24 hours.
Finally, strong-hold spray should be used for more intricate styles and can provide all-day hold. Strong-hold spray should be applied in thin layers, focusing on the areas that need the most hold. After the desired look has been achieved, the spray should be set with a blow-dryer for maximum hold. Strong-hold spray can typically stay in the hair for up to 48 hours.
In general, it is best to avoid using too much spray, as this can cause the hair to become stiff and brittle. Furthermore, it is important to use the right type of spray for the desired look, as different types of spray provide different levels of hold. With the right product and application technique, spray can provide long-lasting hold and style to any hairstyle.
