If you iron your hair and want maximum volume, CHI Iron Guard will be your new best friend. This is a firm-hold hairspray that gives you maximum protection against the highest heat. I like to mist my hair in sections and then brush my hair thoroughly to avoid having crunchy locks. You will notice a severe sticky stiffness when you first apply this product, don't stress. Once you brush through the product, it disappears into the hair completely. This hairspray is my favourite way to protect my hair and ensure my styles hold without sacrificing my volume.
