An edge booster spray bottle is a type of spray bottle that is designed for use in hair styling. It is typically used to provide extra hold and control to the hair, especially around the edges and hairline. This can be particularly helpful for achieving a sleek, polished hairstyle.

Edge booster spray bottles typically contain a styling product such as a gel, wax, or pomade that is used to hold the hair in place. The spray bottle allows for easy application of the product to the hair, allowing the user to target specific areas such as the edges and hairline. The product is then worked into the hair with a brush or comb to create the desired style. Some edge booster spray bottles may also contain ingredients that can provide additional benefits such as nourishing the hair and scalp or adding shine to the hair.

It's important to check the ingredients of the product in the spray bottle before use, as some may contain harsh chemicals that can cause scalp irritation or hair damage.
