Smoothing sprays are hair care products designed to reduce frizz and enhance shine. They typically contain ingredients like silicones, oils, and conditioning agents that help to coat the hair strands, making them appear smoother and more manageable. These sprays can be used on wet or dry hair and are often applied before styling or as a finishing touch. Many people use smoothing sprays to achieve a sleek look, especially those with curly or wavy hair. They can also protect hair from humidity and heat damage, making them popular among individuals who frequently use styling tools like hair straighteners or curling irons.
